Newbie here, so apologies in advance.
In short, we are using a Redlion DA30D to read/write values from an Allen Bradley SLC 5/04. Communications are through RS-232 (DF1).
We aren't having any issues reading values from the PLC, but we are not able to write to the PLC.
We've implemented this setup on a few other machines without this issue, but these machines previously had an AB HMI connected to DF1 whereas this machine did not, so I'm assuming that there may be some channel configuration change needed?
