RS-485 communications with FX1N PLC and a VFD

[Amst]

Hello, I'm trying to delve a little into rs-485 communications for a couple projects of mine.
Until now I've been using a delta vfd and a delta plc so the communication wasn't an issue, but now I'm trying to use a delta vfd(VFD-EL-W) with a mitsubishi plc(FX-1N).
I can't seem to understand how the data transfer works, I can establish the connection but I'm struggling with reading/writing data into the VFD itself.

Is it original FX or clone? What communication card you are using?

Hi Amst,

Change the communication Parameter(09) in the Delta drive as per manual and Check the Page no: 128 to read and write address list to program in Mitsubishi PLC.
