First Scan Bit: New to Mitsubishi

[Conor 4]

Hi guys, I dont normally post on the Mitsubishi forum, but I have a question for you guys. In AB there is normally a first scan bit I am working with a Mitsubishi FX-1S, and cant find the First Scan bit instruction. Basically I would like to make sure that if my machine is powered down mid cycle that when it is powered back on that it completes a purge sequence. I would normally use a first scan bit. Any help on this would be great Thanks, Conor

This is not an intsruction, it's a special bit marker with M8001 address.

Inntele, Correct me if I am wrong, but isn't m8002 first scan? I'm going off memory but I believe it is M8000 = Always on (run contact), M8001 = Always off, M8002 = On for first scan only. Dave

Hi guys, Just checked the manual again. M8000 is Always ON PLC Run M8001 is Always Off PLC Stop M8002 is Initial Pulse (NO) M8003 is Initial Pulse (NC) Of course I was looking for first scan, and they call is Initial Pulse At ;east with your help I was able to find the special bits M8000 etc Thanks again
