Intelligent PROFINET IO device with S7-300 CP
7.2 Configuration (STEP 7 V5.5)
Configuring and commissioning S7 CPs for Industrial Ethernet
126 Configuration Manual, 09/2013, C79000-G8976-C182-13
Note
The IP address of the PROFINET IO device and the IP address of the PROFINET IO
controller must be located in the same IP subnet.
Requirement for configuration in STEP 7
● A PROFINET IO controller must exist in the STEP 7 project.
● The I/O system must have been created already:
Beside the PROFINET IO controller module, you can see the connector symbol for the
PROFINET IO system:
Step 1: Configuring the PROFINET IO device in the I/O system
1. From the "PROFINET IO" > "I/O" > "SIMATIC S7-CP" > ... folder in the hardware catalog,
select the CP type you want to configure as an IO device.
2. Select the device version according to the information in the device-specific part of the
manual for your CP type.
Note
With the Advanced CP, you will need to select
different versions depending on the
intended mode (RT or IRT communication).
3. Connect the CP to the PROFINET IO system (drag & drop).
4. Insert input and output modules with the required IO data length (1 to a maximum of 240
bytes) in the PROFINET IO device.
The following figure shows the configuration table of an S7-400 station as a PROFINET
IO controller. Here, for example, the PROFINET IO device was fitted with 3 modules for
process inputs (I address) and 3 modules for process outputs (Q address).
