square D programming console


Thread Starter



Well, my new job is off to a bang, as I programmed back an old square D PLC with the console. We had the program backed up in the laptop, but the serial port is fried. So, I pulled up the program, and entered it in with the console. This is the old style console I was originally trained on in tech school in 94. It is just arrows, no 'and' 'or' 'load' as such. I managed to remember that you have to do a check on every line, and stubled across the fact that you have to load, load to get the line into memory.

Would like to learn more, in case they want me to modify the program in the future. I was able to figure out how to enter in program, but not able to figure out how to edit.

Thanks in advance.
