4. WIRING 

This chapter describes wiring cautions, terminal configuration and connections. 

4.1 Wiring Cautions 

! 

WARNING 

To prevent electric shock or instrument failure, do not turn on the power until all 

the wiring is completed. 

• To avoid noise induction, keep communication signal wire away from instrument power line, load 

lines and power lines of other electric equipment. 

• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise 

filter. 

− Shorten the distance between the twisted power supply wire pitches to achieve the most effective 

noise reduction. 

− Always install the noise filter on a grounded panel. Minimize the wiring distance between the 

noise filter output and the instrument power supply terminals to achieve the most effective noise 

reduction. 

− Do not connect fuses or switches to the noise filter output wiring as this will reduce the 

effectiveness of the noise filter. 

• Power supply wiring must be twisted and have a low voltage drop. 

• For an instrument with 24 V power supply, supply power from a SELV circuit. 

• A suitable power supply should be considered in the end-use equipment. The power supply must be 

in compliance with a limited-energy circuits (maximum available current of 8 A). 

• Use the solderless terminal appropriate to the screw size (M3).

5. SETTING 

5.3 COM-JG Initial Setting 

To perform communication between a PLC and controller (SRZ), the following items must be set to 

COM-JG. These settings are configured using the configuration tool of the PLC. 

Preparations and an overview of the settings are explained below. 

[COM-JG initial setting items] 

• Controller address 

• Number of continuous accesses 

• Continuous accesses enable selection 

• Static data read/write range 

• Transmission wait time of controller communication 

For the concrete setting method of using the PLC configuration tool, see 8.5 PLC Tool 

Setting (P. 69). 

• Setting preparations 

To configure the COM-JG initial setting items, controller communication must be disabled using the 

DIP switches. 

Change DIP switch No. 7 to ON (controller communication disabled) on the left side of the COM-JG. 

ON 

DIP switch 

ON 

1 2 3 4 5 6 7 8 

OFF 

ON: Controller communication

When you have completed the initial settings of the COM-JG, be sure to return DIP switch 

No. 7 to OFF (controller communication enabled). 

• Setting overview 

• Controller address (required setting) 

This is required in order to make the COM-JG recognize the address of each controller (SRZ 

module). Controller addresses can be obtained automatically by switching DIP switch No. 4. 

For controller address auto obtain, see 5.4 Controller Address Auto Obtain Methods 

(P. 19). 

IMR01Y35-E2 17

5. SETTING 

• Number of continuous accesses (elective setting) 

Each module in the controller (SRZ) has multiple channels, and thus in the case of a 4-channel 

type Z-TIO module, four data areas (data parameters) must be retained for each communication 

item. However, the number of continuous accesses setting can be configured to allow 

communication with just one data area (data parameter) per communication item regardless of the 

number of channel. 

In a static data request, a combined total of up to 40 read and write items can be 

communicated. 

The factory set value for the number of continuous accesses is “4,” and thus when the 

controller (SRZ) configuration consists only of 4-channel type Z-TIO modules, the 

setting does not need to be configured. 

For information on the number of continuous accesses, see also • Number of 

Continuous Accesses (P. 63) in 8.4 Contents Check of COM-JG Initial Setting. 

• Continuous accesses enable selection (elective setting) 

When the communication items of a static data request contain both channel-based data and 

module-based data, the number of continuous accesses setting must be disabled for module-based 

data. 

When only channel-based data is communicated, this setting is not necessary. 

For information on the continuous accesses enable selection, see also • Continuous 

accesses enable selection (P. 64) in 8.4 Contents Check of COM-JG Initial Setting. 

• Static data read range (elective setting) 

When a communication item is specified in a static data request, a read or write request is 

normally sent to the same Modbus register address of all connected controllers (each module of 

the SRZ). 

For example, when a Z-TIO module and a Z-DIO module of an SRZ are connected and a 

communication item of the Z-TIO module is read, the data of the same Modbus register address 

in the Z-DIO module as the communication item specified in the Z-TIO module is read. However, 

because the contents of the Modbus register addresses of the Z-TIO module and the Z-DIO 

module are different, different data is read from each. 

To avoid having unnecessary data read, the range of data that can be communicated for the same 

module type can be assigned. 

This setting is not necessary when the controller consists only of modules that are the 

same type. 

For information on the static data read range, see also • Static data read/write range 

(P. 66) in 8.4 Contents Check of COM-JG Initial Setting. 

• Static data write range (elective setting) 

Same as the static data read range. 

• Transmission wait time of controller communication (elective setting) 

This setting is normally not necessary.

5. SETTING 

5.4 Controller Address Auto Obtain Methods 

To allow the PLC and COM-JG to communicate, the COM-JG must be made to recognize the address 

of each controller (the module addresses of the SRZ). 

Although the PLC configuration tool can be used to configure settings to make the COM-G recognize 

the controller addresses, the DIP switches can be set to have the settings configured automatically. 

For setting method using the PLC configuration tool, see 5.3 COM-JG Initial Setting (P. 17), 

8.4 Contents Check of COM-JG Initial Setting (P. 61) and 8.5 PLC Tool Setting (P. 69). 

• Procedure 

This procedure assumes that the controller (SRZ) communication settings have been 

completed. 

To execute controller address auto obtain, DIP switch No. 7 on the left side of the COM-JG 

must be set to OFF (controller communication enabled). 

1. Set DIP switch No. 4 on the left side of the COM-JG to ON (auto obtain ON). 

Set the controller communication speed with DIP switch Nos. 1 and 2. 

Set the controller communication speed to the same value as the controller (SRZ) setting. 

For the DIP switch setting, see 5.2 DIP Switch Setting (P. 16).

2. Connect the power wiring and the wiring between the COM-JG and the controllers (SRZ). 

There is no need for the COM-JG to be connected to the PROFIBUS when controller 

address auto obtain is executed. 

IMR01Y35-E2 19

5. SETTING 

3. When the power is turned on, controller address auto obtain starts. 

While auto obtain is in progress, the RUN lamp of the COM-JG blinks. 

The obtained addresses are stored in “Controller address” in the COM-JG initial setting items. 

“Controller address” has 31 address spaces, Nos. 1 to 31 [equal to the maximum number of 

controller (SRZ) connections], and the obtained addresses are stored in order from No. 1 

beginning from the lowest-value address. 

The COM-JG checks each controller (SRZ) address against addresses 1 to 99. For this 

reason, a certain amount of time is required to complete auto obtain (up to about 90 

seconds). 

4. When controller address auto obtain is finished, the RUN lamp of the COM-JG stops blinking 

and lights steadily. 

5. Turn off the power and return DIP switch No. 4 on the left side of the COM-JG to OFF (auto 

obtain OFF).

The data in controller addresses 6 to 31 will be “0” (No controller connected). 

The controller address of a Z-TIO module will be the value (decimal) set in the address 

setting switch plus “1.” The controller address of a Z-DIO module will be the value 

(decimal) set in the address setting switch plus “17.”

6. PROFIBUS COMMUNICATION 

6.1 PROFIBUS System Configuration 

For system configuration with PROFIBUS-DP protocol, have to offer the communication information 

about each slave for a master in the form of electronic device data seat (GSD file). 

A manufacturer of PLC (master) has prepared configuration tool for a system configuration of 

PROFIBUS. By combining all GSD files of the slaves to be connected, the configuration tool creates a 

master parameter record containing all pertinent data for the bus system. The configuration of a 

PROFIBUS system is enabled by downloading these data to a master.

6.2 PROFIBUS Communication Data 

6.2.1 Data types and data length of communication data 

• Data access types 

• Static data read/write 

• Dynamic data read/write 

• Error state register 

• Write permission flag register 

• Write control flag register 

• Communication data length 

A maximum of 170 bytes can be read or written. 

• Static data request

40 items (Read items+Write items) 

The communication items which can be specified: 

Data of the 7. COMMUNICATION DATA MAP (P. 28) 

• Dynamic data request 

The communication items which can be requested: 

Data of the 7. COMMUNICATION DATA MAP (P. 28) 

The number of communication items becomes as follows depending on the number of 

connection channels. 

[Read data] Number of static read data × Number of connection channel a × 2 + 

Number of dynamic data × 6 + 12 b ≤ 170 

[Write data] Number of static write data × Number of connection channel a × 2 + 

Number of dynamic data × 6 + 11 c ≤ 170 

a Total number of continuous accesses 

b (Error state register: 1 byte)+(Write permission flag register: 1 byte)+(Write control flag register: 10 bytes) = 12 

c (Write permission flag register: 1 byte)+(Write control flag register: 10 bytes) = 11 

Number of connection channels Number of static data * 

1 channel Maximum of 40 items for both read and write. 

16 channels Maximum of 5 items for both read and write. 

31 channels Maximum of 2 items for both read and write. 

* Calculated with the number of dynamic data equal to 0. The 10 bytes of the write control flag register 

for read data and the 10 bytes of the write control flag register for write data can be omitted. 

6.2.2 Static data request 

• Static data is that which is always read/written from/to the PROFIBUS master such as the PLC. The 

data item is selected by the configuration tool such as the PLC. 

• As the Modbus register address is directly specified, data items of all the controllers connected to the 

COM-JG can be selected. 

• When static data is requested, 1-word (2-byte) data is used for both read and write. 

As the static data register address is set when system configured, it is not required to create a 

sequence program for static data assignment. 

22 

IMR01Y35-E2


6.2.3 Dynamic data request 

• Dynamic data is that which is freely read/written from/to the PROFIBUS master such as the PLC. 

The data item is freely selected by the sequence program. 

• As the Modbus register address is directly specified, data items of all the controllers connected to the 

COM-JG can be selected. 

• When dynamic data is requested, 3-word (6-byte) data is used for both read and write.

− For data read, the current value of relevant communication item is stored. 

− For data write, the current value of relevant communication item is stored. 

If the written data is valid, the written value is returned. 

If the written data is invalid, the present (before data write) value is returned. 

When the data is written, there is a delay in rewriting the data in this 

register as the COM-JG updates the register after rereading the data on 

the controller.

IMR01Y35-E2


6.2.4 Registers assigned to PLC 

Set the register area after the GSD file is read to the configuration tool for the PLC. 

The static data request read, static data request write and dynamic data request registers are set to the 

register area. 

In addition to the above register area setting, the following data is set at the beginning of the register. 

• Read register: Error state (1-byte), Write permission flag (1-byte), Write control flag (10-byte) 

• Write register: Write permission flag (1-byte), Write control flag (10-byte) 

• Error state register 

The first read only 1-byte register consists of bits of error state.

• Instrument error 

In case of the following either, become an error. 

− None of the controllers is connected. 

− COM-JG is hardware abnormally. 

If an instrument error occurs, the RUN lamp at the front of COM-JG flashes (flashes slowly.) 

• Time-out error 

Successive communication time-out occurring twice in the same controller after PROFIBUS is 

initialized causes a time-out error. Communication continues even during the time-out error and 

recovers with no time-out error when the communication returns to normal. 

Time-out time: 3 seconds 

IMR01Y35-E2 25


• Controller communication valid/invalid 

Interlocked with dip switch No. 7 at the side of the COM-JG. 

Factory set value of dip switch No. 7: OFF (0: Controller communication valid) 

• Controller communication initialization 

Indicates the controller communication initialized state when the power is turned on and at this state 

invalidates the data on each communication item. 

• Write permission flag register 

Data may be written by static data request depending on the PLC even if the PLC is not in the RUN 

state. In order to prevent this, the COM-JG is provided with the 1-byte flag register. 

Only when the flag value in this one byte corresponds to “0FH” (hexadecimal), data is written to each 

controller. 

The operation of writing a hexadecimal value of “0FH” to the write permission flag 

register is necessary for both static and dynamic data requests. 

• Write control flag register 

This register controls whether data writing is “permitted” or “not permitted” for each requested word. 

Permitted or not permitted is set by bit for each requested word of a static data write request. 

0: Not permitted 

1: Permitted 

The write control flag register allocates a static data write request for 10 bytes of data with each byte 

containing 8 words, and sets the bit for each word to “permitted” or “not permitted.” 

[Example] Write “permitted” or “not permitted” state when the value of the first byte of the write 

control flag register is A5H (hexadecimal) 

A5H (hexadecimal) = 10100101 (binary)

The write control flag register is only effective for writing of static data requests. 

If you do not need to set write “permitted” or “not permitted” for each word, this setting can 

be omitted.

IMR01Y35-E2


6.3 Processing of Numeric Data Values 

Numeric data values used via communication with the PLC and processed by COM-JG include those 

with and without decimal points and also those with minus signs. 

• For numeric data value without decimal point 

If there is no decimal point, the value is processed as it is. 

In parameters which only have ON or OFF status, 1 = ON, 0 = OFF. 

[Example] 

A signal wire for temperature input is disconnected and the burnout state occurs. 

→ Read value corresponding to communication item address 0021 (burnout state monitor): 

1 (Hexadecimal number: 0001H) 

• For numeric data value with decimal point 

The decimal point is omitted. 

[Example 1] 

When temperature measured value of controller is 120.5 °C 

→ Read value corresponding to communication item address 0000 [measured value (PV)]: 

1205 (Hexadecimal number: 04B5H) 

[Example 2] 

When temperature measured value of controller is 130 °C 


130 (Hexadecimal number: 0082H) 

• For numeric data value with minus sign 

The value is expressed as a 2’s complement value which is obtained by subtracting the minus value 

from the hexadecimal number 10000H. 

[Example 1] 

When temperature measured value of controller is −1 °C 


Hexadecimal number: FFFFH 

(10000H − 1 = FFFFH) 

[Example 2] 

When temperature measured value of controller is −2.5 °C 


Hexadecimal number: FFE7H 

(10000H − 25 = 10000H − 19H = FFE7H) 

The original minus value can be found by revising the WORD value to the INT value on the 

sequence program side.

Communication includes both “Normal setting data” and “Engineering setting data”. 

During RUN (control), the attribute of engineering setting data is RO. To configure 

engineering setting data, the RUN/STOP switch must be set to STOP (control stopped). 

Z-TIO module: Normal setting data No. 1 to 83, 

Engineering setting data No. 85 to 207 

Z-DIO module: Normal setting data No. 1 to 13, 

Engineering setting data No. 15 to 28 

The Engineering setting data should be set according to the application before setting any 

parameter related to operation. Once the Engineering setting data are set correctly, those 

datas are not necessary to be changed for the same application under normal conditions. If 

they are changed unnecessarily, it may result in malfunction or failure of the instrument. RKC 

will not bear any responsibility for malfunction or failure as a result of improper changes in 

the Engineering setting.

8.4 Contents Check of COM-JG Initial Setting 

The contents of the COM-JG initial settings vary depending on the module configuration, number of 

communication items, and communication content. For this reason, before using the PLC 

configuration tool (Programming Software STEP7) to configure each setting, the module 

configuration, number of communication items, and communication content required in the COM-JG 

initial settings must be checked. 

In this example, five communication items are set for the following module configuration. 

• Module configuration

IMR01Y35-E2



• Overview 

To allow the PLC and COM-JG to communicate, the COM-JG must be made to recognize the address 

of each controller (the module addresses of the SRZ). 

Controller addresses can be obtained automatically by COM-JG DIP switch switching, or controller 

addresses can be set using the PLC configuration tool. 

• Setting contents 

Set each controller address (SRZ module address) in order from “No. 1 controller address” to “No. 31 

controller address.” 

Data range: 1 to 99 (0: No controller connected) 

The COM-JG will not access controller address numbers following an address whose set 

value is “0: No connected controller.” 

[Example] 

COM-JG initial setting item Set value 







When No. 4 is set to “0: No connected 

controller”, settings for No. 5 and after 

are invalid (“17” in No. 5 is invalid). 

In this case, the number of connected 

controllers is three. 

• Setting of usage example 

In this example, the DIP switches switching of COM-JG are set so that controller addresses are 

automatically obtained. Addresses are not set in the programming software STEP7. 

For controller address auto obtain, see 5.4 Controller Address Auto Obtain Methods 

(P. 19). 

“Controller address” setting 







No. 1 to No. 4 correspond to the 1st to the 4th module. 

No modules are connected for No. 5 to No. 31, and thus 

when addresses are automatically obtained, these are set 

to “0: No connected controller.” 


The controller address of a Z-TIO module will be the value (decimal) set in the address 

setting switch plus “1.” The controller address of a Z-DIO module will be the value 


IMR01Y35-E2 63



• Overview 

For a 4-channel type Z-TIO module, four register addresses will be allocated for one communication 

item, for example when the Modbus register addresses of the measured value (PV) are 0000H to 

0003H. When these are set using the PLC configuration tool, four items must be specified as static 

data request items. However, if “Number of continuous accesses” is set to “4,” the static data request 

item for all four channels can be set by simply specifying the item of the first register address. 


For each module (No. 1 to No. 31), set the number of data of the communication item selected by the 

static data request. 

Data range: 1 to 85 (Factory set value: 4) 

In a static data request, a combined total of up to 40 read and write items can be 

communicated. 

The factory set value for the number of continuous accesses is “4,” and thus when the 

controller (SRZ) configuration consists only of 4-channel type Z-TIO modules, the setting 

does not need to be configured. 

As a basic rule, the “Number of continuous accesses” is set to the number of channels used 

for each module. However, when only module-based data (such that one module has only 

one data item) is set in the static data request (for example “Digital input (DI) state” of the 

Z-DIO module), set the “Number of continuous accesses” to “1.” 


In this example, there are other modules in addition to a 4-channel type Z-TIO module, and thus the 

number of continuous accesses setting is required.

No. 1 to No. 4 correspond to the 1st to the 4th module. 

No. 4 (Z-DIO) has 8 channels, however, the data 

specified for the Z-DIO module is all module-based 

data, and thus “1” is set. 

No. 5 to No. 31 are not connected, and thus the settings 

remain at “4,” the factory set value. 

No. 1 to No. 31 correspond to No. 1 to No. 31 

of "Controller address" in the COM-JG initial 

setting items. 

64 

IMR01Y35-E2



• Overview 

The “Number of continuous accesses” is set for each controller (module), and thus when “4” is set, 

each communication item of a module accesses four channels. However, some of the communication 

items, such as “RUN/STOP transfer,” have only one data item per module. If four channels of data are 

requested for this type of data, unnecessary register addresses will be accessed, and thus the “Number 

of continuous accesses” setting should be disabled for module-based data. 


Select whether or not the number of continuous accesses setting is enabled for each communication 

item selected in a static data request. 

When the number of continuous accesses setting is disabled, read and write are only performed with 

respect to one register of the selected communication item. 

Select enable/disable for each communication item of a static data request by bit. Eight items (eight 

bits) is one byte, and thus the maximum of 40 items (Groups 1 to 40) is set using five bytes. 


Groups 1 to 40 are divided into five sets of eight groups each, and enable/disable 

continuous access is set by bit for each group. 

Bit data 0: Continuous accesses disabled 

1: Continuous accesses enabled 

When only channel-based data is communicated, this setting is not necessary. 


In this example, both module-based data and channel-based data are communicated, and thus the 

continuous access enable select setting is necessary. 

Read and write of a static data request are set as shown below. 

• Read item: Z-TIO module: Measured value (PV), Set value (SV), RUN/STOP transfer 

Z-DIO module: Digital input (DI) state, RUN/STOP transfer 

• Write item: Z-TIO module: Set value (SV), RUN/STOP transfer

Among the previously discussed communication items, there are three module-based items: 

RUN/STOP transfer (Z-TIO), digital input (DI) state (Z-DIO), and RUN/STOP transfer (Z-DIO). For 

read and write of these items, disable the number of continuous accesses setting.

Groups 9 to 16, Groups 17 to 24, Groups 25 to 32, and Groups 33 to 40 do not use this setting, and 

thus the factory set value of 255 (all enabled) should remain unchanged.

• Overview 

The static data read/write range can be set to prevent the reading of unneeded data and the writing of 

incorrect data. 

When a communication item is specified in a static data request, a read or write request is normally 

sent to the same Modbus register address of all connected controllers (each module of the SRZ). 

For this reason, when modules that have different Modbus register addresses are connected and a 

communication item is specified, the wrong data may be read or data may be written to other than the 

intended communication item (depending on the module). 

For example, when a Z-TIO module and a Z-DIO module of an SRZ are connected and a 

communication item of the Z-TIO module is read, the data of the same Modbus register address 

in the Z-DIO module as the communication item specified in the Z-TIO module is read. However, 

because the contents of the Modbus register addresses of the Z-TIO module and the Z-DIO 

module are different, different data is read from each. 

Example Z-TIO module: 006DH → RUN/STOP transfer 

Z-DIO module: 006DH → DO minimum ON/OFF time of proportioning cycle 

To avoid having unnecessary data read, the range of data that can be communicated for the same 

module type can be assigned. 


Five channels each can be set for read and write. This means that five different types of Modbus 

register addresses can be handled. 

For each channel, set the number of connected modules that have the same Modbus register address 

and the number of communication items. 


The “Number of connected modules” is set in the upper hexadecimal byte, and the 

“Number of communication items” is set in the lower byte. 

This setting is not necessary when the controller consists only of modules that are the same 

type. 

For Modbus register address of the SRZ, see 7. COMMUNICATION DATA MAP (P. 28). 

IMR01Y35-E2 67



In this example, the Modbus register addresses of the connected Z-TIO and Z-DIO modules each have 

different contents, and thus the static data read/write range setting is required. 

To enable static data read/write access by module, it is recommended that a table be created that shows 

the correspondence between communication item groups and controller addresses. 

For one type of module, set the valid data range to one channel for read and one channel for write.

8.5 PLC Tool Setting 

This section explains the procedures for using the programming software STEP7 to configure settings. 

8.5.1 Setting procedure 

• COM-JG initial setting 

The procedure for configuring COM-JG initial settings is explained below. 

Before configuring COM-JG initial settings, be sure to set DIP switch No. 7 to ON 

(controller communication disabled). After you have completed the COM-JG initial 

settings, be sure to return DIP switch No. 7 to OFF (controller communication enabled).

8.5.2 General procedures 

When configuring either COM-JG initial settings or communication item settings, first follow the 

general procedures below. 

Registering a GSD file is only performed when configuring COM-JG initial settings; it is not 

necessary when configuring communication item settings. 

• Creating a new project 

When configuring communication item settings, you can save the project that you created 

when configuring COM-JG initial settings under a different name. This will enable you to 

omit “PLC master setting” and “Register a COM-JG.” 

1. Start programming software STEP7. 

2. Select the menu command File → New…, and creating a new project. 

In this example, the project name is “COM-J.” 

When configuring communication item settings, use a different project name than the 

project name you used for COM-JG initial settings.

This concludes the general procedures. 

IMR01Y35-E2 81


8.5.3 COM-JG initial setting 

The following four items are set as COM-JG initial setting items. 



• Static data read range 

• Static data write range 

Repeat the following procedure [from Data parameter setting (P. 82) to Monitor and modify of 

variable (P. 96)] for each initial setting item. The example below explains how to set the “Number of 

continuous accesses.” 

See 8.4 Contents Check of COM-JG Initial Setting (P. 62). 

• Data parameter setting 

1. Double-click “COM-JG” registered to set each controller (SRZ) communication item. 

Double-click 

82 

IMR01Y35-E2


2. Set the number of data of the communication item in “Number of Channel” in “Device-specific 

parameters.” In this example, “4” is set for the “Number of continuous accesses” (because there 

are four modules). 

For “Continuous access enable selection,” “Static data read range,” and “Static data write 

range,” set “5.” 

Sets “4” 

3. Set the number of read/write items to “Group read/write allocation.” 

In this example, the number of read items set to 1, and the number of write items, to 39. 

The number of items that can be set by the COM-JG is 40 maximum including both read 

and write items. 

If you are setting “Static data read range” and “Static data write range” at the same time, 

set 2 read items and 38 write items. 

Sets as 1 read item and 

39 write items 

IMR01Y35-E2 83


4. Set read and write items in order from “Group 1 ID (base ten).” 

The set value sets the Modbus register address of the controller (SRZ) connected in a decimal 

number. In this example, make the setting as follows. 

Read item: Group 1 ID (base ten): 65024 (No. 1 Number of continuous accesses) 

Write item: Group 2 ID (base ten): 65024 (No. 1 Number of continuous accesses) 

Because the number of read items is set to “1,” a read item can only be set for Group 1 ID 

(base ten). Write items must be set for Group 2 ID (base ten) and following groups. 

Blank items will be the factory set value “65535.” 

For Modbus register address of COM-JG initial setting items, see 7.5 COM-JG Initial 

Setting Items (P. 57). 

Set “65024: No. 1 Number 

of continuous accesses” as 

the read item. 

Set “65024: No. 1 Number 

of continuous accesses” as 

the write item. 

5. After the allocation of data parameters is finished, click “OK.” 

84 

IMR01Y35-E2


• Configuration setting 

1. Select “COM-JG” and then set the write permission flag register. 

Select “Write permission” from the hardware catalog and then drag and drop it to the COM-JG 

rack detail window. 

Always set “Write permission” regardless of the contents of communication items. 

In addition, always set “Write permission” to the first line. 

In this example, the error state register (“Error state”) setting is omitted. If you set the 

error state register (“Error state”), be sure to set it on the first line. (“Write permission” 

will be on the second line.) 

In the COM-JG initial settings, the write control flag register (“Write control”) is not 

used. 

Drag & drop 

IMR01Y35-E2 85


2. Set the number of the word of static data. 

Read/writes, data length of one item become a single word. 

Number of read words = Number of communication items × Number of read items 

= 4 × 1 = 4 

Number of write words = Number of communication items × Number of write items 

= 4 × 1 = 4 

Select “Static input word” and “Static output word” from the hardware catalog and then drag and 

drop it to the COM-JG rack detail window. 1/2/4/8/16 words are available. 

In this example, the number of data of “Number of continuous accesses” is “4” (there are four 

modules) and the number of read and write items is one each. Thus four words are set for both 

read and write. 

Always locate “Static input word” above “Static output word” on the rack detail 

window. 

Select and then set the number of word of the COM-JG initial setting from among 1, 2, 4, 

8 and 16 words so that the total number of words becomes the same as “Number of 

communication items × Number of read (or write) items.” 

For example, if “Number of communication items × Number of read items.” Corresponds 

to five words, select one word and four words. 

Select the number of 

the word of read data, 

and do drag & drop 


the word of write data,

3. Set the number of the word of static data. 

Read/writes, data length of one item become a single word. 

• Number of read words = Total number of words of each static data read range channel 

Number of words of static data read range channel 

= Number of communication items in static data read range channel (continuous access enabled) × 

Number of connected channels* in static data read range channel + 

Number of communication items in static data read range channel (continuous access disabled) × 

Number of modules in static data read range channel and in number of connected channels 

• Number of write words = Total number of words of each static data write range channel 

Number of words of static data write range channel 

= Number of communication items in static data write range channel (continuous access enabled) × 

Number of connected channels* in static data write range channel + 

Number of communication items in static data write range channel (continuous access disabled) × 

Number of modules in static data write range channel and in number of connected channels 

* The number of connected channels is the total number of continuous accesses. 

If there are no static data read/write range settings, all ranges are read/write ranges. 

In this example, the number of static data words is set based on the following conditions. 

Number of channels (total number of continuous accesses): 11 

Number of read items [Group 1 to 5 ID (base ten)]: 5 

Number of write items [Group 6 to 8 ID (base ten)]: 3 

Number of continuous accesses: No. 1 Number of continuous accesses: 4 

No. 2 Number of continuous accesses: 4 



Continuous accesses enable selection: Continuous accesses enable selection 1 to 8: 35 

(Group3, 4, 5, 7, 8 are invalid) 

Continuous accesses enable selection 9 to 16: 255 




Static data read range: Static data read range CH1: 771 (0303H) 

Static data read range CH2: 258 (0102H) 

Static data read range CH3: 0 



Static data write range: Static data write range CH1: 770 (0302H) 

Static data write range CH2: 257 (0101H)

Calculate the number of words of static data from the above table. 

Number of words of static data read range CH1 

= Number of communication items in static data read range channel (continuous access enabled) × 

Number of connected channels in static data read range channel + 

Number of communication items in static data read range channel (continuous access disabled) × 

Number of modules in static data read range channel and in number of connected channels 

= 2 × 10 + 1 × 3 = 23 (Number of “◦” in the table) 

Number of words of static data read range CH2 


Number of read words = 23 + 2 = 25 words 

and 

Number of words of static data write range CH1 

= Number of communication items in static data write range channel (continuous access enabled) × 

Number of connected channels* in static data write range channel + 

Number of communication items in static data write range channel (continuous access disabled) × 

Number of modules in static data write range channel and in number of connected channels

cannot be written. 

The data specified in a 

static data request 

cannot be read or 

cannot be written. 

The number of words set in the 

configuration is less than the 

number of data set in the data 

parameters. 

The group setting and the group 

read/write allocation setting in 

the data parameter settings do 

not match. 

• The order of the write items is 

opposite the order of the read 

items. 

• A group without a read/write 

allocation is set. 

Make sure that the number of data set in the 

data parameters is the same as the number of 

words set in the configuration. 

The number of data set in the data 

parameters is determined by the combination 

of the following items. 

• Number of channel 

• Number of setting Group 


See the equation for calculating the number 

of read/write words on the previous page. 

Make sure the group setting matches the 

group read/write allocation setting in the data 

parameter settings. 

[Example] 

When the number of channels is “1” and 

the group read/write allocation setting is 

10 reads / 30 writes: 

• Groups 1 to 10 are read items and Groups 

11 to 40 are write items. 

• When the number of read request words is 

“5,” Groups 1 to 5 will be read-requested, 

but Groups 6 to 10 will not be 

read-requested. 

• When the number of write request words is 

“5,” Groups 11 to 15 will be 

write-requested, but Groups 16 to 40 will 

not be write-requested.
