CHAPTER 12 PROGRAM EXAMPLES
12.1.6 Redundant CPUs and GM1 Function Block service
This section describes an example of Function Block service between two FEnet I/F modules
composed of communication redundancy. The system ([Figure 12.1.57]) configuration shows
the example that realizes the network duplication by using two FEnet I/F module between a
redundancy CPU and a GM1 CPU.

[Figure 12.1.57] Redundancy system configuration
The program method for a redundancy CPU is the same as the existing method but the single
CPU makes the program by using the redundancy Function Block. The table below describes
the example to send the data by using TCP/IP and the data contents for communication.
