Hello everyone, Looking for some help. My program keeps getting hung up when I am storing #40 and #60 into MI 1. Can anybody take a look at this and see what I'm missing? I could only attach the subroutine as it was too big. Thank you so much, Scott scott_ladder.vlx
hi there I was debugging a program on a V700 over a direct connected Ethernet link to the PLC and laptop while debugging eventually visilogic would randomly close with the attached error screen I could easily restart visilogic and reconnect the link to continue debugging so more of an inconvenience than anything any help would be appreciated
I'm a new user of Ladder Logic and M91 PLC's. I'm trying to debug a program I have uploaded off of an old PLC. I understand that in U90 there is no way to force input/output states. Considering this how can you check that your logic is correct? E.g. how can I check that a certain combination of inputs will cause a change of state or particular output? [i don't consider a red flow of logic sufficient, especially as I can only see it for the power on state.] Thanks
