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 com-
puter 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 Mod bus RTU protocol, communication can
be performed with the RS-485 terminal. (Refer to section 6.23.)
