Hey all.
I’m curious to see if it’s possible to change a message instruction in a MicroLogix 1100 (or any other AB PLC/PAC) from a read to a write and/or vice versa. It would be a message instruction reading from / writing to a SLC type device. I can change the data table address in the target device (using either a move or sequence) but I can’t find any information as to what the file for the “communications command” is.
Anybody ever done this and/or know what file it is (and if you can access it)?
