Guys;
Factory A:
I have 5 compressors running with ABB inverters. The inverters have modbus RTU built-in. They are monitored and controlled by HC900 via modbus RTU communication.
Factory B:
I have 2 compressors (stand-by) operating with Danfoss softstarters (also have modbus RTU built-in). They are controlled by ML50 so far via modbus RTu communication.
The distance between factory A and factory B is about 100 meter (open air).
The question is: how can I connect both factories into one controller i.e. the HC900. I wish to switch on the starter(s) if the compressors in factory A are overloaded.
HC900 still has Ethernet and RS232 ports. ML50 only has RS232 port.
Thanks guys,
Keith
