hi there, long time reader, first time posting.
I have a Micrologix 1200 and when I added a RTC to the PLC it started smoking a bit. I pulled the clock and tested all my outputs. My discrete signals and AI card are fine. My AO card is causing problems. The software detects the AO card and everything looks as it should in the ladder logic, but the card is not sending out an actual 4-20mA sig or a 0-10VDC sig (using my multimeter). I replaced the card thinking it was damaged, but the same problem exists with the new one. Has anyone experienced anything like this? Any tips?
