Connecting and setting HMI

• Connect the LHMI to the relay either directly from the main unit port X1.1 to
the relay's X0/HMI port or through station network from the main unit port X1.1
to the relay's Network 1 port. The HMI's service port X1.2 is intended for local
service access to the relay using PCM600 or the WHMI.
• Always connect the SHMI through the station network.
• Depending on the planned network topology communication, adapt the HMI
settings to establish communication between the relay and the HMI. The service
port settings must be set correctly to allow access to the relay either directly or
through the station network.
