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.
