Figure 3.16 - The above architecture shows an illustrative example of the hardware used in
the CPU-700-E3R redundancy.
- Two Ethernet paths
- Two MB-700 modules allow complete redundancy
- Two CPUs with main and backup roles
- A RIO module scans the MODBUS variables.
Note: The I/O modules are only included in the racks where the RIO module is present.
