2.3.7 Communication operation
Using the PU connector or RS-485 terminal, you can perform communication operation from a personal computer
etc. When the PU connector is connected with a personal, FA or other computer by a communication cable, a user
program can run and monitor the inverter or read and write to parameters.
For the Mitsubishi inverter protocol (computer link operation), communication can be performed with the PU
connector and RS-485 terminal.
For the Modbus RTU protocol, communication can be performed with the RS-485 terminal.
