mb coil or output won't go to set mode

[pesi78]

Hello,

I have an issue I have made a new ladder routine "NO LIMITS" with soubrutine "TEST 1" but I' can't put output or coil or MB to high mode. I can set it only mannualy othervise won't work. I have also looked that output or MB in not used in no other place.  Any suggestions for this problem?

1.  Make sure you're calling the subroutine.  The fact that you bit doesn't go on with a SET coil hanging on the rail indicates the logic isn't being solved.

2.  Never, ever, ever use a NO contact with a toggle coil output.  The result will be a bit that chatters with every other scan.  Use a positive transitional instead.
