1. MPI – LAN Ord. No. 9352 - LAN 


1.1. Description 

The MPI – LAN cable connects the computer with a MPI - or a Profibus - interface 

(PLC) by using a TCP/IP network. 

1.2. System requirements 

Operating systems 

- Windows 98 + SE/ME/NT/2000/XP 

Software 

- PLC – programming software (e.g. PG2000, Step© 7, S7 for Windows, 

Microwin) 

- PLC - VCom software (see chapter 6) 

Hardware 

- Network interface card (NIC) 10/100MBit installed in the computer. 

The NIC must provide a RJ – 45 interface. Older network interface card types are often 

using BNC interfaces. 


1.3. Connection possibilities 

MPI – LAN directly connected to the computer. 


MPI – LAN connected with the computer using a switch or hub. 


MPI – LAN Connection possibilities with operator panel 


1.4. Installation 

Hardware 

Connect the MPI – LAN cable (short side) with the MPI interface (9 pins) of the S7 - 

PLC. The network connector from the long side of the cable (RJ – 45) should be 

connected as described: 

MPI – LAN cable to computer: 

Connect the network connector from the MPI cable to the network card interface (RJ 

– 45) of your computer. 

MPI – LAN cable to switch/hub: 

Connect the network connector of the MPI cable to the uplink port of your switch/hub. 

If you are using an auto - negotiated switch you can put the network connector into a 

free port of your choice. 

MPI – LAN with a operator panel: 

Connect the cable of the operator panel with the PPI/MPI/PROFIBUS – interface of 

the PLC. Connect the MPI – LAN cable (short side/9 pin plug) with this interface 

(PPI/MPI/PROFIBUS) so that both cables (MPI – LAN and Operator Panel) are 

plugged into one interface. 

Connect the MPI – LAN with the network as described above. 

There must be a serial communication with the operator panel if this op is new/used at 

the first time. Therefore connect your operator panel with the serial COM interface of 

your computer. After the communication has been running successfully the panel is 

ready to be connected to the PLC. 

The PLC supports the cable with power. The cable provides an alternative power 

supply interface which can be connected by a 24V/DC adapter (screw clip or a MPI – 

net adapter). As soon as the cable is supported with power it shows its software 

version on the display and begins to test its internal components. 

Software 

To communicate with the PLC, please install the PLC - VCom software, as described 

in chapter 6.2. 

You also need programming software (e.g. PG 2000, Step© 7, S7 for Windows, 

Microwin) to work with the PLC.

please click on properties. 


12. In the properties of the channel unit you 

can see all „available connections”. 

Choose the newly created one and click 

again on „Properties”. Now you can see 

all the variables which has been 

created for this connection. In fact this 

connection is a new one so there will be 

no variable in the list. To add a new 

variable click on „New”. 

13. Now set up the name of the variable 

(e.g. „S7LAN_MW0”) and other 

configuration data. Our example has 

the following configuration: Name: 

„S7LAN_MW0“, Data type: „unsigned 

16 - Bit value“, Length: „2“, Address: „MW0“, Format adaptation: 

„WordToUnsignedWord“. Click on „Choose” beside the Address to define the 

address from the variable. Example configuration: The data area from the variable 

is set to „Mark“ and the address is set to „Word”. The edit box „MW“ is set to „0”. 

14. Confirm all open dialogs with „OK“. 

15. The connection needs to know which network interface card it should use to send 

data via the Ethernet. Open the „System parameters“ dialog from the context 

menu (right click on TCP/IP). 

16. Choose the registry card „Unit“ and set the „logical device name“ to your network 

interface card (usually the name of the NIC begins with a „TCP/IP - > „).

h. Microwin v4.0 using the PPI Multimaster mode 

Please be sure that the interface configuration is correct as described 

in point b 

The PPI Multimaster mode has been developed for the purpose that multiple devices 

can communicate parallel with one PLC. The following steps describe how to 

configure this mode. 

1. The cable must be set to PPIMulti mode. Therefore go to the „Config” menu. 

2. Set it to „PPIMulti“ with the cursors of the cables case and press return to confirm 

this configuration. The menu „Messages” (first menu) displays now „PM“ in the 

first line. 

3. Now you have to set the PG/PC interface. You can do this by using the Microwin 

software. Start the Microwin software. 

4. Click on „Set PG/PC Interface“ at the left side of the applikation window. See the 

picture on the right for further details. 

5. Choose the entry „PC/PPI cable(PPI)“ and click on „Properties”. 

6. In the registry path „PPI“ you can for example the „HSA“. 


7. In the registry path „Local Device“set the COM Port („Connection to”) to the one 

provided by the PLC VCom software. 

8. Confirm your settings with „OK“ and click on „Communications” above the „Set 

PG/PC Interface” Button you have used before. 


9. Click on „Double click to Refresh „. Now the software is searching for the PLC. 

10. If the PLC could be found the dialog changes as shown in the picture below: 




1. Start the „S7 for Windows” software by using the link on your 

desktop or use the link in your start menu (standard is 

„Programs\S7 for Windows\S7 for Windows“) 

2. Choose File - >Preferences... to configure the communication 

configuration between the computer and the PLC. 

3. A new dialog appears which provides to set up a lot of 

configuration data about the communication with your PLC. 

4. Choose the first registry card „Interface“ (standard) and set up the configuration 

data as descriped below: 

� Area: „Preferences from:“ � PC 

� Area: „PLC Type:“ � S7 

� Area: „Protocol:“ � MPI - Umsetzer 

� Area: „Serial Port:“ � Choose the virtual COM port which has been 

created by PLC - VCom (e.g. „COM 4”). 

� Area: „Baud Rate“ � Choose the speed you want to use at the bus (e.g. 

„115200“) 

� Area: „MPI Converter:“ 

o Activate the checkbox „Only Master at the Bus“ if you have only one 

PLC in the bus. 

o Leave the fields „ S7W MPI Address“ and „MPI Address PLC“ as it is. 

o The number in the listbox „Max MPI Address“ must be higher than the 

PLC with the highest station address in your MPI bus. Otherwise every 

PLC which is higher than this number will not been seen (e.g. if there is 

only one PLC in your bus „15“ is more than enough). 


5. After the software is configured and the PLC - VCom is 

connected with the PLC, please click „Select PLC” in the 

area „MPI Converter“. A new dialog appears where you 

can select the desired PLC. While this dialog opens you 

can see right now (in the bottom right of the task bar) the 

green blinking PLC VCom icon . This means that the 

software is already talking to the PLC. 

6. The dialog displays all the PLCs that can be found in your MPI bus. Select the 

desired one and confirm with „OK”. 

7. Close the preferences dialog by pressing the „OK“ button. 

8. Back in the main window press the „PC Block List“ button for 

testing the new established communication configuration. 

9. Please wait a moment for the software to read the desired blocks 

from the PLC. The blocks will be displayed in the listbox below 

the menu bar (see picture to the right). 

The communication between the software and your PLC is 

established. 

If you had any trouble up to this point go ahead in chapter 8.1 

Frequently Asked Questions. 


1.6.4. Merge two PLCs together by using a network 

By merging two PLCs together you will be able to transfer data from one PLC to 

another. Merging PLCs together is only possible with two S5/S7 PLCs or one S5 PLC 

connected with a S7 PLC. 

Each MPI – LAN cable can establish up to 8 connections. A S5 - Gateway up to 2. 

For this example we have merged a S7 with a S5 PLC. 

As an interface between S7 and S5 the MPI – LAN cable and the S5 – Gateway 

module have been used. 

MPI – LAN Configuration 

The MPI – LAN cable can be configured by using the Web interface (see chapter 3.1) 

or by using the keys on the device.

“500k“, “1,5M“, “3M“, “6M“, “12M“. 

HINT: The baud rates “3M“, “6M“ and “12M“ can only be configured by cable. These higher baud rates 

(from “3M” to “12M”) will be overwritten by the PC. To get sure that this will not happen configure (in 

the cables menu) “Lock” in the sub menu “Data”. (This sub menu is also described at the bottom of the 

next page) 

- Master 

In the case that the cable is connected with only one passive station, configure 

“Master” to the cable to determine that the cable is configuring itself. In all other 

cases please configure “Multimaster“ to the cable. 

- local No 

Changes the station number of the cable. Hexadecimal values of “00“ to “7E“ are 

available. 


- HSA 

HSA stands for Highest Station Address. Configure the highest station number to the 

cable which is connected to the MPI bus. Possible values: “from PC“, “15“, “31“, “63“, 

“126“. 

If you are using “from PC“ the cable takes the PG configuration. 

- Profile 

Select “Standard“ to use the standard PROFIBUS mode. “DP“ (Decentral Peripherie), 

“DP/FMS“ (Field Message System) and “MPI“ (Multi Point Interface) are deviations of 

the PROFIBUS standard.

power, and lengthen only signals Ltg_A and Ltg_B 1:1. Be sure to put the shield on 

the SUB – D plug. Also be sure to use terminating resistors where applicable (at the 

bus ends).

The S7 – LAN module easily connects the PC with a MPI or Profibus interface by 

using a TCP/IP – Network. 


Operating Systems 


Software 

- SPS – programming software (e.g. PG2000, Step© 7, S7 for Windows, 

Microwin) 


Hardware 

- Network Interface Card (NIC) 10/100MBit 

The NIC must provide a RJ – 45 interface. Older network interface card types are 

often using BNC interfaces. 



S7 – LAN directly connected with the PC. 


S7 – LAN connected to the PC by using a switch or hub. 


S7 - LAN connection possibilities with a operator panel 



Hardware 

The S7 – LAN module will be plugged in to the PLC directly. The PLC can be 

connected with the module by using a network device as decribed below: 

S7 – LAN to Switch/Hub 

Connect the S7 – LAN module with the switch/hub by using a standard patch cable. 

If you are using a crosslink cable so connect this one into the uplink port of your 

switch/hub. In the case that you are using a switch with the auto – negotiating 

function you can put the network cable into a port of your choice. 

S7 – LAN to PC 

The module gets connected with the PC directly by using a crosslink cable. 

S7 – LAN with a operator panel 

The cable of the panel must be plugged into the PPI/MPI/PROFIBUS interface of the 

PLC. Plug the S7 – LAN between the panel and the PLC (in the same interface). 

Connect this module with the network as described above. 

There must be a serial communication with the operator panel if this op is new (used 

at the first time). Therefore connect your operator panel with the serial COM interface 

of your computer. After the communication has been running successfully the panel is 


Power is taken out of the PLC. 

Software 

To start a communikation with the PLC, please install first the PLC - VCom software. 

(Install description can be found in chapter 6.2). 

Also you will need a software to work with the PLC (e.g. PG 2000, Step© 7, S7 for 

Windows, Microwin).

connection is a new one so there will be 

no variable in the list. To add a new 

variable click on „New”. 

13. Now set up the name of the variable 

(e.g. „S7LAN_MW0”) and other 

configuration data. Our example has 

the following configuration: Name: 

„S7LAN_MW0“, Data type: „unsigned 

16 - Bit value“, Length: „2“, Address: „MW0“, Format adaptation: 

„WordToUnsignedWord“. Click on „Choose” beside the Address to define the 

address from the variable. Example configuration: The data area from the variable 

is set to „Mark“ and the address is set to „Word”. The edit box „MW“ is set to „0”. 

14. Confirm all open dialogs with „OK“. 

15. The connection needs to know which network interface card it should use to send 

data via the Ethernet. Open the „System parameters“ dialog from the context 

menu (right click on TCP/IP). 

16. Choose the registry card „Unit“ and set the „logical device name“ to your network 

interface card (usually the name of the NIC begins with a „TCP/IP - > „). 

17. Confirm with „OK“. 

Now you are able to start the communication. Stop it by pressing 


To clean up errors faster the WinCC Software offers a tool named „Channel 

Diagnosis”. This tool analyses all connections from your WinCC software. For 

demonstration purposes please stop the newly started connection from your WinCC 

explorer. 

18. Start the software „Channel Diagnosis“ using your link in the start menu.

established. 




2.6.3. Direct communication using TCP/IP with Step7© v5.3 (CP 

mode) 

This communcation does not need a simulated virtual COM port (PLC – VCom is not 

needed). A direct connection will be established to your network device. The CP 

mode is also called ISO protocol or RFC1006. 

At the moment it is not possible to exchange a CP completely. 

This descritption needs an existing project. Please read the Step 7 manual for more 

information about creating new projects. 

1. Execute the Step 7 software by using the link on your 

desktop or use the link in your start menu. 

2. Open your existing project and start the „Set PG/PC 

Interface...“ dialog by using the menu „Options“. 

3. In the listbox „Interface Parameter Assignment 

Used:“ choose „TCP/IP - > XXX“. The „XXX“ stands for 

the network interface card you want to use. Confirm 

your input with „OK“. 

6. 

4. Back in the main 

window call, by 

using the menu 

„Options“, 

„Configure 

Network“. 

A new window 

appears. 

5. This window 

shows the available devices and busses (in 

this example there is a PLC „CPU 315“ with 

the station address “2” using the “MPI” bus). 

For the Step 7 software version 5.2 you need the SIMATIC NET 

package, 

otherwise the Step 7 software will not show the desired entries 

(TCP/IP, etc.) because it is not supported. 

The Step 7 software version 5.3 has this package included after 

installation. 


7. In the explorer „Selection of the network“ choose 

„Subnets“ and do a double click on „Industrial Ethernet“. 

The left part of the window should change like the picture 

(below) shows. 

8. Now add a dummy PLC which will be used for the CP mode 

later. In the explorer „Selection of the network“ choose 

„SIMATIC 300“ from the branch „Stations“ to add a new virtual 

PLC. This takes effect to the left part of the window (see picture 

below). A rectangle with a orange (not always orange) marked 

area is shown. 

9. This is our dummy PLC which is called 

„SIMATIC 300(2)“. Change this with a right 

click on the object. From the context menu 

choose „Object Properties...“ to open the 

“Object Properties“ dialog. 


10. Type in the edit box “Name“ the 

new name of the PLC (e.g. “Dummy 

PLC for CP mode“).Confirm the new 

name with a click on “OK“. 

The rectangle should be updated 

by the application. 

11. In the explorer “Selection of the network“ choose the branch “Stations” and from 

there choose the object “PG/PC“. The graphical presentation will be extended 

with a „PG/PC(1)“ object. 

13. The “Properties - PG/PC“ dialog offers the 

possibility to create new interfaces. 

Therefore choose the registry card 

“Interfaces“. With the registry card 

“Interfaces” opened click on “New…”. 

14. Select 

“Industrial 

Ethernet“ from 

the selection 

box and confirm with “OK“. 

12. To configure the newly created 

object perform a right click on the 

„PG/PC(1)“ object and in the context 

menu choose “Object Properties…“. 


15. Now configure the IP address and the subnet mask from your computer (e.g. IP 

address: „192.168.2.106“, subnet mask: „255.255.255.0“). Before confirming with 

“OK” choose “Ethernet(1)“ as the subnet you want to use. 

16. The dialog “Properties – PG/PC“ should have two interfaces added to his list. 


17. Select the registry card “Assignment“ and mark “Ethernet port(1)” by using the list 

“Configured Interfaces:”. In the list “Interface Parameter Assignments in the 

PG/PC:“ choose “TCP/IP - > XXX“. “XXX“ stands for the network interface card 

you want to use. 

18. Assign the active connection to the device. 

19. If this warning message appears just ignore it. 

Press “OK”. 

20. Be sure to activate the 

checkbox “S7ONLINE 

Access:”. 

Confirm the dialog with “OK“. 


21. Because of your “PG/PC(1)” configuration the graphical presentation should have 

changed (as shown in the picture below). The yellow marked connection (green 

line) between “PG/PC(1)“ and „Ethernet(1)“ shows that the assigned interface 

(„Ethernet(1)“) from the “PG/PC(1)“ object is used for the „S7ONLINE - Access“. 

22. Now “Save and Compile…” your configuration by using 

the menu “Network“. The option “Compile changes 

only“ is good enough for our purpose. 

23. A small window appears with a lot of error and warn 

messages. Do not panic that is part of the plan. As you 

can see in the graphical section the “Dummy PLC for 

CP mode“ has a red marked area. This signals that this 

object is currently not working. To solve this problem 

perform a double click to the “Dummy PLC for CP mode“ or perform a right click 

to the object and choose “Open Object”. 


24. A new window opens (the hardware configuration). On the right you can see the 

hardware explorer where you should choose “Rail“ from the branch „SIMATIC 

300“ - > „RACK - 300“. The picture below shows how the window should appear 

after you have added the “Rail”. 

25. In the hardware explorer open the branch: “SIMATIC 300“ - > “CPU - 300“ - > 

“CPU 312“. From there double click on “6ES7 312 - 1AD10 - 0AB0“. The 

application is now adding this cpu to your rail. The view should have changed as 

shown below. 


26. In the hardware explorer mark “V2.0“ from the branches “SIMATIC 300“ - > 

“Industrial Ethernet“ - > “CP 343 - 1“ - > “6GK7 343 - 1EX11 - 0XE0“ and select 

one of the green slots at the bottom left (see the dark green marked slot). Now 

rapidly click twice on “V2.0“ to add the object to your rail. 

27. Before the application can add 

the object to your rail you have to 

configure it. Therefore set, in the 

registry card “Parameters” of the 

new dialog, the IP address of the 

used S7 – LAN module (e.g. 

“192.168.1.55“) and select 

“Ethernet(1)“ in the list “Subnet:” 

(the newly created interface). 

The subnet mask should fit to the 

given IP address 

(e.g.“255.255.255.0“). Confirm 

with “OK“. 

HINT: In our example we used a computer with the IP address 192.168.2.106 and a S7 – LAN module 

with the IP address 192.168.1.55. Because of the different subnets (red marked numbers) of the 

devices a direct communication cannot be established. To solve this problem you can change the 

subnet mask from the computer to 255.255.252.0. Now the computer is available for exact three 

subnets 0, 1 and 2. Read the chapter 8.1 “Frequently Asked Questions“ for further informations. 


28. Right click on “CPU 312“ in 

the bottom left sector and in 

the context menu choose 

“Object Properties…”. 

29. In the dialog “Properties – CPU 312 - (R0/S2)“ press the “Properties…“ button. In 

the new dialog you can assign the MPI address to the CPU and choose the 

subnet the CPU should use. Select the “MPI(1)” “Subnet:” we have created in the 

steps before. The address (e.g. “10”) of the CPU should be the only one in the 

entire network. Also be sure that the next higher address is also free for use (it 

will be used later for the CP object). Save your configuration with “OK”. 

30. Perform a right click on the 

“CP 343 - 1“ object you have 

created in the steps 27 and 

28. Choose “Object 

Properties…” from the 

context menu. 


31. Another property dialog will open. Set the name of the CP object to “S7 – 

LAN“ (optional). Also set the MPI address which should be exact one station 

higher than the address you have given your “CPU 312“ in the step 30 (e.g. 

„10“ has been set for the “CPU 312“ object. So “11” has been the only right 

address for the CP object). Confirm with “OK”. 

32. „Save and Compile…“ the hardware configuration and the network configuration. 


33. After you have saved the network configuration the graphical presentation of the 

devices and busses should appear as shown in the picture below. As you can see 

there are no more red marked sections. 

The following description assumes that you are already involved in configurating the 

S7 – LAN module. 

If you have any trouble in the following steps please read chapter 2.6 „Operating 

instructions“. 

33. The last thing you have to do before the connection is established is to configure 

the S7 – LAN module. You can access the configuration menu vai web browser. 

In the address bar you must enter the S7 – LAN IP address. Press the “Enter” key 

to start the web based configuration menu. 

You do not know the S7 - LAN IP address? In this case you can use the PLC – 

VCom software to determine the S7 – LAN IP address. Tip: The “Configuration“ dialog 

shows every connected device (to the computer or the network). See chapter 6 “PLC 

– VCom“ for detail. 

34. Choose the desired language in the first site and click on “CP - Mode” in the 

second site. The only option you can configure for the CP mode is the 

“Destination - PLC”. You can set “255”. In this case the S7 – LAN module 

connects automatically to the directly connected PLC. If you are using the 

IPS7Link software you could set the station address of the PLC CPU which is 

connected directly to your S7 – LAN module (in this example “2”). Or type in the 

station address of the PLC CPU which you have configured in step 30 for the 

“CPU 312” (e.g. “10“). 

35. In the menu “MPI/PROFIBUS“ set the “Locale Station Address” which you have 

configured to your CP object in the step 32 (e.g. “11”). 

36. Back in the main application window (the SIMATIC Manager) set the real existing 

PLC into “Online” state. Therefore just click on “Online” in the menu “View”. 


37. To test the communication open the branch of 

your real existing PLC (e.g. “SIMATIC 300(1)”). 

The branch below the PLC is the CPU Type (e.g. 

“CPU 315“). A additional red symbol is displayed 

next to the standard CPU symbol. Open this 

branch, too. The next branch you should open is 

named as „S7 Program“ (e.g. “S7 Program(3)”). 

Finally click on “Blocks” to get a complete list of 

available blocks from your PLC. 

As soon as the blocks are shown, right beside the device explorer, the CP 

communication with the PLC over the S7 – LAN module is established. 

HINT: It is not possible to establish a normal communication and a CP communication at the same 

time. If you do so only the CP mode should work properly because it has a higher priority. 


2.6.4. Merge two PLCs together by using a network 

By merging two PLCs together you will be able to transfer data from one PLC to 

another. Merging PLCs together is only possible with two S5/S7 PLCs or one S5 PLC 

connected with a S7 PLC. 

Each S7–LAN module can establish up to 8 connections. A S5 - Gateway up to 2. 

For this example we have merged a S7 with a S5 PLC. 

As an interface between S7 and S5 the S7 – LAN and the S5 – Gateway module 

have been used. 

S7 – LAN Configuration 

Call the configuration site S7 on S5/S7 Bridge of the S7 – LAN module. The following 

page will appear. 

HINT: You have to buy the S7 on S5/S7 license to see this page. Otherwise there will be a page with 

the notice that you haven’t bought the license. 

Connection-type 



DB Active (*1) Establishes the connection by using the TCP protocol. 

DB Passive (*1) Waits until another device establishes the connection with it. 

S7 Active (*2) Establishes the connection by using the TCP protocol 

S7 Passiv (*2) Waits until another device establishes the connection with it. 

(*1) DB Active and Passive are using, for data exchange, the function block FC 55 (send) and FC 56 

(receive). 

(*2) S7 Active and Passive are using for data exchange a special bridge function. 

Station-number 

Defines the locale communication partner. This station must be in the same MPI bus 

as the S7 module. 

Data-block 

Determines the data block which is used for communication. 

Data-word 

Determines the memory range which is used for communication. At least 32 byte for 

each connection. 

IP-Address 

Enter the IP address of the partner which should be connected with the S7 module. 

You can enter the IP address of a S5 – Gateway to establish a connection to an S5 

PLC. 


TSAP 

Every connection must be unique. To identify a unique connection you have to enter 

the Transport Service Access Point. Both devices must have the same TSAP. Length 

must not exceed 16 characters. 

Poll time 

The module has to read data frequently from the partner. To minimize the traffic on 

the network you can rise up this poll time. Every unit delays the polling for 10 

milliseconds. For example 20 units delays the module to read every 200 milliseconds 

from his partner. Notice that a high value slows the communication down. 

If you would like to establish a connection with a S5 Gateway you should set the S7 

module to be the active partner (setting DB Active as connection type). Also be sure to 

set the poll time between 60 and 100 units because the PG port cannot send data 

faster.

2. In the main page select the desired language to go on with the configuration 

pages. 

3. If a password for general access is defined, you are asked for it. 

On the top of the window you can see the unselected menus (gray background) and 

the selected menu (green background). The configurations are listed up below of the 

menu hyperlinks and are marked with a yellow background. The button “Save” is 

displayed below the configuration part and is always on the left. 

Content 

Set up the main configuration part of the cable. 

Operating System 

Displays the current operating system version. 

Name 

Enter the name of your MPI cable 


TS-Function 

Switches the TeleService function “ON“ or “OFF“. 

use BUS-Configuration from PC 

Select “YES“ if you want the cable to take the configuration from the PC. 

Booting 

This configuration sets the mode of the cable. 

The following booting modes are available: 

Booting mode Description 

Automatic Selects the used mode automatically. 

MPI/PROFIBUS Use this for the standard MPI/PROFIBUS configuration. 

PPI 9K6 PPI mode with 9600 baud. 

PPI 19K2 PPI mode with 19200 baud. 

PPI MMaster PPI mode. There are more than 1 Master devices in the bus. 

Special Special mode offers you the possibility to configure the used bus 

configuration by yourself. 

Protocol-Type 

Select the protocol version that should be used to communicate on the bus. 

Protocol-Type Description 

Automatic Selects the protocol type automatically. 

V5.1 Faster than v5.0 

V5.0 (old) More stable than v5.1. 

The following configuration is only available with the booting option set to “Special”. 

In the case that you are using another booting option this parameters will be ignored. 

Baudrate (only when Booting Special) 

Set the desired speed on the bus. 

Databit (only when Booting Special) 

Defines how many usable bits will be transferred per block. A high value speeds up 

the connection. 

Parity (only when Booting Special) 

To make the transfer more checkable you can set the parity. 

Stopbit (only when Booting Special) 

Configure how many stop bits should be send per block. A high value could make the 

communication more stable. 

Network 

Special configurations are needed in the network. On this page they can be set more 

comfortable. 

DHCP-Client 

Since the version 1.68 you can start a DHCP client for the MPI – LAN cable. In this 

case the IP address of the cable is set automatically. Requires a DHCP server. If 

there is no DHCP server in the network the cable sets the IP address automatically to 

a standard value. 


IP-Address 

To make the module recognizable in the network you have to set the IP address. 

This address consists of four numbers separated by a point. Each number can be a 

value between 0 and 254. It has to be unique which means that the IP address does 

not appear more than 1 times in the whole network. Ask your system administrator 

for a usable IP address for the cable. 

SubNet-Mask 

The format of the subnet mask is identical to the format of the IP address. It 

describes the subnet (IP address range in the network) of your cable. In the picture 

above it is set to 255.255.255.0 which means that the cable is a member of the 

subnet 1 (third number of the IP address). 

Gateway-Address 

For the reason that the cable can receive requests from other subnets you can define 

a gateway. The format is identical to the format of the IP address. Usually the 

gateway is another computer or a router which routes the received packets to 

another subnet. 

RFC1006 

Also known as CP-Mode (CP = Communication Processor) 

Destination-PLC 

Enter the PLC number of the device you want to communicate with directly. The 

value 255 defines that the MPI – LAN cable takes the PLC it is connected with. 

S7-Subnetz-ID 

This ID marks the used bus unique. Enter the S7-Subnet-ID of the bus where the 

MPI – LAN cable is connected with. 

Busparameter 

You could choose if at connection start the BUS-Parameter are determined 

automaticaly or if the configuration from the S7/MPI-LAN is used (See 

MPI/PROFIBUS). The Automatic is only possible when one of the PLC’s is cyclic 

distributing the Bus - parameters. 

State 

In this bloc you see if at minimum one RFC1006 communication is active and on a 

per channel basis the connected IP-address and PLC. Errors are also displayed here. 


MPI/PROFIBUS 

The MPI/PROFIBUS needs specific configurations, too. This configurations are listed 

up on this page. 

Baudrate 

Sets the speed of communication. Alternatively you can set it to the option “From 

PC“ (takes the configuration from the PC) or “Automatic“ (selects the baud rate 

automatically). 

Highest Station Address 

Enter the maximum station address. A high value slows down the communication. 

Local Station Address 

Enter the station address of the cable. This number must be unique and has to be 

smaller than the number in the Highest Station Address field. 

Profile 

Select “Standard“ to use the standard PROFIBUS mode. “DP“ (Decentral Peripherie), 

“DP/FMS“ (Field Message System) and “MPI“ (Multi Point Interface) are deviations of 

the PROFIBUS standard. 


TUNING 

In this dialog some functions are inserted which could not be inserted in the other 

dialogs. 

Set to Default 

The configuration of the S7/MPI-LAN is erased and set to default. 

There will be an Query to acknowledge the erase, keep in mind that the IP-address 

of the S7/MPI-LANs is changed to the default-address 192.168.1.56 and additionally 

the DHCP-Client is activated. 

Change language of WebSide to 

Click on the link to change the used language of the WebSide to German. 

Restart 

The S7/MPI-LAN is restarting straight after the receive of the click, so no response is 

possible to send. 


Display 

In this Dialog you could remotely access the Menü of the display. The usage is 

exactly the same as when you are using the built in Keyboard. With „Display“ a 

refresh of the LCD-Display is done. 

S7 an S5/S7 Bridge 

This configuration page makes it possible to define connections with other PLCs for 

data exchange. The MPI – LAN cable supports up to 8 connections. 

HINT: You have to buy the S7 on S5/S7 license to see this page. Otherwise there will be a page with 

the notice that you haven’t bought the license. 

Connection-type 



DB Active (*1) Establishes the connection by using the TCP protocol. 

DB Passive (*1) Waits until another device establishes the connection with it. 

S7 Active (*2) Establishes the connection by using the TCP protocol 

S7 Passiv (*2) Waits until another device establishes the connection with it. 

(*1) DB Active and Passive are using, for data exchange, the function block FC 55 (send) and FC 56 

(receive). 

(*2) S7 Active and Passive are using for data exchange a special bridge function. 

Station-number 

Defines the locale communication partner. This station must be in the same MPI bus 

as the MPI cable. 

Data-block 

Determines the data block which is used for communication. 

Data-word 


Determines the memory range which is used for communication. At least 32 byte for 

each connection. 

IP-Address 

Enter the IP address of the partner which should be connected with the MPI cable. 

You can enter the IP address of a S5 – Gateway to establish a connection to an S5 

PLC. 

TSAP 

Every connection must be unique. To identify a unique connection you have to enter 

the Transport Service Access Point. Both devices must have the same TSAP. Length 

must not exceed 16 characters. 

Poll time 

The cable has to read data frequently from the partner. To minimize the traffic on the 

network you can rise up this poll time. Every unit delays the polling for 10 

milliseconds. For example 20 units delay the module to read every 200 milliseconds 

from his partner. Notice that a high value slows the communication down. 

If you would like to establish a connection with a S5 Gateway you should set the cable 

to be the active partner (setting DB Active as connection type). Also be sure to set the 

poll time between 60 and 100 units because the PG port cannot send data faster. 

More information about connecting two PLCs you can read in chapter 1.6.4. 

VarSteuern 

With this Option you could access up to 16 variables of PLC’s which are connected 

on the same MPI/Profibus as the S7/MPI-LAN. In the Demo version is only a single 

operand possible. 

If a password for VarModif defined, you encounter a password check at access to 

this Dialog, if the password is wrong or not inserted the modification of operandvalues 

is not permitted. With the Button on the bottom of values you could reread the 

status value. If the PLC is not accessible or the operand could not be read the Text is 

colored red and displayed a corresponding error message. 

According to the Display format the Modify value is inserted, erroneous inputs are 

ignored and not transferred to the PLC. The transfer of the value is started with the 

buttons “->” on the right side. Only one of the modified value is transferred, after 

transfer the status values are reread and displayed.

Hardware 

The S5 – LAN module will be plugged in directly on the S5 PLC. Use the network 

interface as described below: 

S5 – LAN to switch/hub 

Connect the network cable of the S5 LAN module to the switch/hub. If you are using 

a crosslink cable, connect this cable to the uplink port of the switch/hub. If you are 

using an auto - negotiating switch you can put the network cable to a free port of your 

choice. 

S5 – LAN to computer 

Use a crosslink cable to connect the S5 LAN module with the computer, directly. 

Power is taken of the PLC. Alternatively the module can take the power of a 24V/DC 

external power supply (if the PLC does not have a 24V/DC power supply e.g. AG - 

95U and AG - 100U). 

HINT: Do not use the 24V output of the AG on a AG - 90U.

established. 




4.6.4. Direct communication with WinCC 6.0 

This communication uses the H1 - ISO - on TCP protocol. Also called RFC1006 

protocol. It is used in the S5 world of Siemens to communicate via ethernet with the 

CP 1430 TCP. Therefore you have to enter the TSAP and SSAP. The S5 - LAN 

module accepts every name for SSAP and TSAP. 

This protocol does also fit with WinCC (choose S5 TCP/IP Layer 4). 

HINT: If you want to use this protocol you have to configure 102 as S5 - Server - Port to the S5 - LAN 

module. 

The configuration part of the S5 – LAN module is descripted as a short version from 

now on.More information about configurating the S5 – LAN module you can find in 

chapter 4.6 „Operating instructions“. 

1. First start the S5 – LAN Manager by using the link in your start menu. 

2. Press the button „Suche im lokalem Netz“ and select the S5 – LAN module which 

should be used for the communication with WinCC. 

3. Use the button „Einstellungen“ to open the configuration dialog. Set the „S5 - 

Server - Port“ to „102“. 

4. Confirm your configuration with „OK“ and close the program with “Beenden”. 

5. Next step is setting up the PG/PC interface to configurate a useful assignment. Go 

to the control panel and click on “Set PG/PC interface “. 

6. Search in the “Access Point of the Application” 

for “TCP_IP:“. If this entry is available go ahead 

with step h otherwise choose „“. 

7. This dialog offers you the possibility to add a 

new access point. Set the name of the “New 

Access Point” to „TCP_IP:“ and set the 

“Description” (e.g. „WinCC S5 - LAN (TCP/IP)“) 

you want to set. Click on “Add“ and “Close“ the 

dialog. 


8. Select the network interface card you want to 

use and choose in „Access Point of the 

Application“ this entry: “TCP_IP: � 

TCP/IP � XXX“. ”XXX” stands for your network 

interface card. Save the configuration with “OK“. 

9. Now start WinCC 6.0. Create a new project or 

open a existing one. 

10. In the explorer (on the left) you can see 

some content of your project. Also there is the 

“Tag Management”. Click with the right mouse 

key on “Tag Management“ and in the context 

menu choose “Add new driver...“. 

11. Choose the communication driver “SIMATIC S5 Ethernet Layer 4.CHN“. Get 

back to the program with “Open”. The “Tag Management” has changed because of 

that. 

12. Expand the branch “SIMATIC S5 ETHERNET LAYER 4“ and perform a right 

click on “S5 - Transport (TCP/IP)“. In the context menu choose “New connection...“. 

13. In the properties dialog you can set the name of the connection (e.g. “S5 – 

LAN“) and use the button “Properties“ to set the “IP address“ from the S5 – LAN 

module for this connection. 


14. In the section „READ - Function“ activate “Fetch Active“. Both section are 

containing “Local TSAP“ and “Remote TSAP“ as parameters. You can configure 

these parameters as you wish. Confirm the connection parameters with “OK“. 

15. Back in the main window you should a the new branch in “S5 - Transport 

(TCP/IP)“ from “SIMATIC S5 ETHERNET LAYER 4”. 

The settings for a direct communication with WinCC are finished. 


4.6.5. S5 – Gateway communication 

Requirements: S5 - LAN Manager 

Supported since firmware version 0.44 of the S5 - Gateway. 

Only the connection type “ISO - on - TCP” is supported by the S5 - Gateway. Only 2 

connections are possible! 

1. Start the S5 - LAN Manager and search for your S5 - Gateway module. As soon 

as it is found select it and click on the button “S5 - Gateway - Verbindung”. A 

dialog appears where you can set up the gateway connection. 

2. In the lower part of the dialog you will find the connection list where you select the 

connection you want to edit. 

3. At the top of the dialog a edit box called “Name:” allowes you to give the 

connection a logical name. 


4. Below set up the position of the “Konfigurations - Datenbausteins“ (configuration 

datablock). Therefore just set the position of the datablock (DB) to the left edit box 

(e.g. “1” for DB1). Then set up the starting point which specifies when the 

configuration area starts (the edit box is called “ab DW”). 

5. Set the connection type list box (its called “Verbindungs - Typ“ in the dialog) to 

“ISO - on - TCP - Verbindung“. This connection type uses the TCP - Port 102. 

6. The polling cycle (ms) specifies the elapsed time until the S5 - Gateway reads and 

checks the configuration area wether something has to be done. If this box is set 

to zero the configuration area will be read without making a break. 

7. Only the IP address of the member (“Partner”) can be set in the address part 

(“Adressen”). The IP address of the S5 - Gateway you have to can set as known 

by using the S5 - LAN Manager (see chapter 6.4). 

HINT: If 0.0.0.0 is set as member IP address the IP address will not be checked on connection start up. 

In this case every device which knows the TSAP (see Point 9) of the S5 - Gateway can establish a 

connection. 

8. Configure to both devices the TSAP (Transport - Service - Access - Point). This 

one consists of 16 characters and identificates the connection. This will be 

needed to identify a connection to a IP address which has more than one 

connections running. 

HINT: Since firmware version 0.45 of the S5 - Gateway every device can use any TSAP to establish a 

connection if the member TSAP is not set (TSAP - Length (“Länge”)= 0). Therefore the member just 

needs to know the IP address and the TSAP of the S5 - Gateway. 

9. The communication is compatible to the “ISO - on - TCP - Verbindung“ connection 

of the CP343 - 1. In this case only the required connections of the S7 - CP343 - 1 

has to be configured. Set the TPDU - size (Transport - Protocol - Data - Unit) to 

512. So you have specified that the maximum package size which can be received 

or transmitted is 512. 

HINT: The communication to the S5 PLC will be set up by using the PG interface. On the PG interface 

a baudrate of 9600 Bit/s is used. Of course this needs longer run times for protocols. For that reason 

be sure that the member is not too fast by sending data to the S5 - Gateway module. Otherwise a 

order jam is possible. An sending interval of at least 600ms (we suggest 1000ms) is required by a data 

amount of 256 Byte. 

Finally the S5 - Gateway communication is set up.

modules. It makes it possible to connect with other PLCs.. More detailed 

information about the dialog elements you will get in chapter 4.6.5 S5 – 

Gateway communication. 

To send a firmware file (see point 5) you have to load this file first. Do this with 

the button Load firmware file. A dialog to choose the desired firmware file 

appears. These firmware files have the extension *.bin for binary. Choose the 

desired one and confirm with OK. Now firmware spezific information will be 

shown in the section Firmwareinfo.

activated. Choose the module you want to update and press this button to 

send the firmware. 

Hint: It is highly recommended that you only update your module if there are any problems or you 

have got any important information to do so. 

While sending the firmware file to the module do not disconnect the module from the 

power supply or the network. Doing so will cause a crash and there will be the danger 

that the module will not work correct.

This must not be changed at all. 

S5 - Server - Port 

TCP/IP – Port number. This port controls the S5 - LAN - LINK protocol/VIPA – 

protocol. 

DHCP/AutoIP 

If this box is active the module searches on start up a DHCP – Server. If no server 

can be found after 3 tries (can take some seconds), the module searches for an IP – 

address of the „Auto - IP“ address range. 

auto Subnet 

If active, the module is calculating the subnet – mask automatically. For example the 

valid subnet – mask for 192.168.0.80 is 255.255.255.0. In this case the dialog 

element Subnet – Mask can be empty. 

IP - Adresse 

The IP – address can be typed in here. (If “DHCP/AutoIP” is not active).

Here you can change the subnet – mask. If you enter 0.0.0.0 the „auto Subnet“ – 

routine is used. 

Default - Gateway 

The IP – address of the router (if you are using the LAN – module on a router). 

Take care that the IP – address of your cable/module (does not matter which LAN - 

device) is corresponding with the IP – address of your computer and is only given for 

the specified device. If you are not sure which IP – address to use ask your network 

administrator.

8. Troubleshooting 

8.1. Frequently Asked Questions 

Q: When connecting to a cable this error message appears. Why? 

A: The meaning of this error message is that the subnet mask (defined by your 

computer) defines a too small area for use. The IP address from your computer 

uses an bigger area than defined by the subnet mask. In fact that the subnet 

mask masks this IP address out, the cable cannot be recognized. 

There are two ways for solving this problem: 

1. Solution: Change the IP address from your computer so that it is in the area 

defined by the subnet mask. To make this example connectable we had to 

change the IP address of the computer to 192.168.001.100. 

2. Solution: Alternatively you can rearrange the defined area of the subnet mask, so 

that the IP address from your computer can be recognized by the cable. In this 

example we need to change the subnet mask to 255.255.252.000 (the 002 of the 

computer IP address is meaningful, because the 2 is binary 10, so the subnet 

mask masks this IP out because of 255. To correct this mistake we have to 

rearrange the area of the subnet mask by changing the second value of the right 

to 252. Binary this is 11111100 (you remember the 002 (binary 10) ). With this 

subnet mask active we arranged the valid IP address area from 192.168.000.XXX 

to 192.168.003.XXX. 


Q: My cable is connected with the SPS by using the COM – port but the 

communication is not running or stops after a couple of hours. 

Both are returning the same error messages if an 

error occured. 

This error codes will be described below: 

A: It is possible to test the COM – port. 

Therefore start the PLC – VCom 

application and right click on the icon in the 

top left corner of the dialog (see pricture to 

the right). Choose „Info über PLCVCOM...“. 

The Info – dialog appears (right picture). 

Right click on the PI – Logo (lower half of the 

dialog) to start the following dialog. 

Now you can test the COM – port. 

If this error message comes up please check your cable 

connection with the COM – port. 

Configure the COM – port to the edit – box 

„Zugriff auf“. It must be the one which has the 

cable connected to it. 

Click on „1x“ to connect with the COM – port. 

Click on „DL“ (All time access) to loop this 

connection until an error occurs. 

If this one appears the COM – port is ready but the 

application got a wrong answer from the PLC or the 

cable. 

This one describes that your COM – port is not avaiable. In 

this case be sure that no other program is using the COM – 

port. If no one does be sure your COM – port is working 

fine
