13.6.1 Setting up the connection of the Open User Communication with the redundant
S7-1500R/H system
Introduction
The S7-1500R/H redundant system can communicate with other devices via Open User
Communication.
You set up the connections in the user program, e.g. via the "TSEND_C" instruction. The
S7-1500R/H redundant system does not support configured connections.
You can either set up the connections either via the device IP addresses or via the system IP
addresses of the PROFINET interfaces.
Open User Communication via a system IP address of the redundant system S7 1500R/H
If you set up the connection via a system IP address, then communication always takes
place via the primary CPU.
Recommendation: Always use a system IP address for Open User Communication.
