Configuring Io Devices As Optional - Siemens SIMATIC ET 200AL System Manual

5.9.2.2

Configuring IO devices as optional

Requirements
● IO controller supports configuration control for IO systems, for example CPU
1516-3 PN/DP as of firmware version 1.7
● STEP 7 V13 SP1 or higher
● The rules (Page 241) for the establishment and operation of a standard machine project
have been considered.
Procedure
To configure an IO device as optional IO device, proceed as follows:
1. Create a project.
2. Configure an S7-1500 CPU firmware version V1.7 or higher as IO controller.
3. Configure the required IO devices and assign the IO devices to the IO controller.
4. Configure the port interconnection between the devices.
Note
A port interconnection between the devices of the IO system is mandatory for IO systems
to be customized with the user program. Otherwise, no order would be defined for the
interconnected IO devices. The following settings are possible for the partner port:
• Specific partner port of an IO device (selection via the "Partner port" drop-down list in
• "Setting partner port by user program" (selection via the "Partner port" drop-down list
5. Select the IO device you want to mark as optional.
6. Select the area "PROFINET interface [X1]" > Advanced options".
7. Enable the "Optional IO device" option.
8. Repeat steps 5 to 7 for all IO devices to be configured as optional.
9. Load the configuration onto the CPU.
