Wiring of Communication Terminals
PLC or PC is used for master control, with the inverter as the slave, which are connected through RS485. It can realize single master and single slave communication or single master and multiple slaves communication. With the increasing connection units, the communication system becomes more easily to be interfered, so it is suggested to connect wires as follows (see Annex for communication protocol):
