I have a technical question.
I have a chiller that contains 3 controllers inside its control
panel. Those controllers are daisy chain connected through Modbus/RTU (RS485) loop end with PLC (as a Modbus master controller).
It is required to control /monitor the chiller signals via BMS.
So, if I consider the DDC (BMS Panel) as Master controller, and the chiller controllers are slaves, shall I override (remove the network wires from) Modbus chiller PLC master controller, and consider the other three controllers as slaves?
please support me.
Thanks and regards,
Mohammad.
