Posted 27 Aug 2015 Hello to all; thank you for this very interesting website. I was just reading a programm of a machine and I noticed the " P_Off" flag preceding a MOV instruction. I wander how a falg which is always Off can activate an output. Can someone tell me how this flag work? or a doc which describe the behavioural of this flag. Hope to read you soon Best regards.

Posted 27 Aug 2015 The chances are that someone inserted the P_Off contact to disable that MOV instruction. My guess would be it is a leftover line from initial testing. Share this post Link to post Share on other sites
