Open User Communication via a device IP address of the redundant system S7 1500R/H
In redundant mode, the redundant system can establish or terminate connections and send
or receive data via every device IP address.
If you set up the connection via a device IP address, then communication takes place via the
associated CPU. In the event of the failure of the CPU, then the entire communication via the
device IP addresses of this CPU fails.
Setting up a connection via a system IP address
The following describes how to establish a connection to another CPU via a system IP
address of a PROFINET interface of the redundant S7 1500R/H system.
You set up the connection in the user program of the redundant system S7-1500R/H with a
TSEND_C instruction. You create a corresponding TRCV_C instruction in the user program
of the other CPU.
The procedure is described using the example of a TCP connection between the
S7-1500R/H redundant system and a CPU 1516-3PN/DP.
Requirements
A redundant system S7 1500R/H, e.g. 2 CPUs 1513 1PN
System IP address of the PROFINET interface X1 is enabled.
CPU 1516-3PN/DP
The PROFINET interfaces X1 of the CPUs 1513R and the PROFINET interface X2 of the
CPU 1516-3PN/DP are located in the same subnet.
