Therefore,the inverter can be set as a slave to communicate with the marter (such as PLC and PC) which has the same communicatinport and protocol; also, user can use a inverter as the master to communicate with several inverters produced by ourcompany via RS485 port to realize multi-machine linkage. Besides, you can connect the RS485 port to remote keyboard torealize remote operation.This inverter support MODBUS-RTU,the following is the particular instruction for the inverter’s communication protocol.7-2.7-2.7-2.7-2.InstructionInstructionInstructionInstructionofofofof communicationcommunicationcommunicationcommunicationprotocalprotocalprotocalprotocal7-2-17-2-17-2-17-2-1....CommunicatingCommunicatingCommunicatingCommunicatingmodemodemodemodeInverterInverterInverterInverterasasasasaaaa slaveslaveslaveslaveFig.Fig.Fig.Fig.7777－1111 NetworkingNetworkingNetworkingNetworking diagramdiagramdiagramdiagramofofofof inverterinverterinverterinverterMulti-deviceMulti-deviceMulti-deviceMulti-devicelinkagelinkagelinkagelinkageFigFigFigFig 7777----2222NetworkingNetworkingNetworkingNetworking diagramdiagramdiagramdiagramofofofof multi-devicemulti-devicemulti-devicemulti-devicelinkagelinkagelinkagelinkage7-2-7-2-7-2-7-2-2222....CommunicationCommunicationCommunicationCommunicationmodesmodesmodesmodesThe inverter can be used as both master and slave in RS485 net. If it is used as a master, it can control other inverters madeby our company to realize multi-machine linkage.If it is used as a slave, PC or PLC can be set as a master to control it. Theconcrete communication modes are shown below:(1) (1) The inverter is a slave in the network. It communicates in ‘point to point’ mode. The inverter will not responseto the command sent by the master via broadcast address. |
