Posted 13 Dec edited. One thing I noticed is that by assigning linx as node 1 or node 2 etc, the processor seems to be recognized longer than with linx at node 0. Posted 7 Dec I selected the com port and set device to PLC-CH0 and tried to auto configure but it failed baud and parity test.

Posted 6 Dec I tried to connect with DF-1 but no luck. Tomorrow morning I am going to disconnect thr dataliner and see gradley it makes a difference, but the machine is in use right now. The processor only has a DB-9 connector on it.

I mis-spoke in my previous post when I said DB-9 serial.
I did try it at They can’t communicate using DF1 protocol. As far as it being the cable I can connect with several other plc-5’s with no issues.
