CSE-H55N does not support multi-connection. If the communication between HMI and Mitsubishi is just via a RS422 driver based protocol (not Modbus), you can choose from the following topologies: Topology 1: <img src="https://www.eztcp.com/en/support/qna_files/200731-topology-1.jpg"> Topology 4: <img src="https://www.eztcp.com/en/support/qna_files/200731-topology-4.jpg"> Note that, topology 4 is ONLY useful in case the physically distance between HMI devices are long.
