Configuring ET 200SP

Introduction
In the S7-1500H redundant system the devices communicate in a PROFINET ring via MRP.
Define the media redundancy role of the devices.
Assign the I/O modules for the various automation tasks in the three tunnel sections to the
three ET 200SP distributed I/O systems.
Set the watchdog time for each ET 200SP. If you set a higher watchdog time, then a failure
of the IO device on interruption of the PROFINET ring can be avoided.
Defining MRP role for ET 200SP in the PROFINET ring
Proceed as follows to define the media redundancy role for the ET 200SP distributed I/O
systems as devices in the ring:
1. In the network view of STEP 7, select PROFINET interface X1 of one of the two CPUs.
2. In the Inspector window, navigate to "Properties" > "General" > "Advanced options" >
"Media redundancy".

3. Click the "Domain settings" button.
