Connecting Relays: Alarm, Fault

 

If used, connect the relay output(s) to equipment that will be triggered by each relay. 

Note:

     Take care to ensure proper wiring for intended function: normally open and / or 

normally closed. 

3.6   Connecting Ethernet Gateways 

Connect the Ethernet output from the controller to the gateway(s). 

Note:

    If multiple gateways are in use, their Ethernet ports may be daisy chained or an 

optional Ethernet switch can be used to connect all gateways and the controller 
onto the same local subnetwork. 

Connect the Modbus cable to the gateway output as depicted below.
