4.2.3 Creating a PROFINET IO System
Requirement
Configuring PROFINET IO Devices
You have arranged a module rack in the station window, and it is now opened
(slots in the rack are visible).
PROFINET IO Controller
You can use the following devices as an IO controller:
• A CPU with an integral or insertable PROFINET interface (integral, such as
CPU 317-2 PN/DP)
• A CP along with a CPU (e.g. CP 443-1 Advanced connected to a suitable
S7-400-CPU)
• A PC station (e.g. with CP 1612)
Procedure
1. In the "Hardware Catalog" window, select an IO controller (e.g. CPU 317-2
PN/DP).
2. Drag-and-drop the module to a permissible row in the module rack. The
"Properties – Ethernet Node" dialog box then opens.
Here you can do the following:
- Create a new Ethernet subnet or select and existing one
- Set the properties for the Ethernet subnet (such as the name)
- Set the IP address of the IO controller
3. Confirm the settings with "OK"
The following symbol appears for CPUs with an integral IO controller:
This symbol is the "peg board" for the IO devices in the IO system.
External IO Controllers
CPs that can be used as external IO controllers support numerous options for
communications. As such, they are not "predetermined" for use as IO controllers.
If you use an external IO controller (e.g. CP 443-1 Advanced), then you have to
insert an IO system after inserting the IO controller (context menu command:
"Insert PROFINET IO System").
