DELTA PLC VFD Modbus Communication

This video explains the Delta L Series VFD and Delta DVP-10SX PLC modbus communication in detail. The communication between the plc and the VFD is through the 2 wires SG+ and SG- which are used for transmit and receive. Many devices can be connected in daisy chain network in this communication differentiated by station address included in each modREAD and modWrite command. In this example in am able to control the start and stop operation of the VFD through PLC Modbus commands. I am also able to access the parameters of the VFD like current frequency, etc through the modREAD Command. In case you have any queries please feel free to leave your comments.
