According to programming manual terminals XD2D is just for Drive-Drive connection, not for Drive-PLC.

Dear Friend,
it Only connect with other controller ( Compressor controller) via RS485 ( 3-wire ), and the ABB driver will be run follow with speed request from controller transfer to ABB driver. Not with PLC.
Please advise me.
Regards.

It doesn't matter what you connect to this port, unless it's ABB drive.
