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.
