C.11.4 OPC UA TCP host port redundancy with redundant CIU 888s and data
synchronization between host systems
In this configuration, both CIU 888s in the redundant configuration are
connected to the Honeywell Experion PKS ((see FIGURE C-8)) and to
other Modbus TCP/IP hosts. The CIU 888s are connected to Experion
FTE Networks via FTE A & FTE B ports. CIU 888s acts as non-FTE
nodes on FTE network. Each ethernet port has its own unique IP
address and is configured in Modbus TCP/IP hosts for communication.
Also, LAN ports can be connected to LAN network which can further be
accessed by other Modbus TCP/IP client host systems.
