Hi

The problem is on screen, I programming only in LAD. I can't download program to Jazz. When I try Properties:  Run-time error '6': Overflow and U90Ladder close.

Where is bug?

Thanks

I haven't looked at your program, but the error message says it all for me.  Please look at the help files, use Index to find Input, then look at Positive Transition Contact where you will find info about the total number allowed (255) and a whole host of relevant information.  Likely the main relevance is in the section about "Decreasing the number......"

Also, and probably the main culprit, your screenshots show 2 I/O actions in the one ladder rung, which might also be the issue.  Separate things out.  There is no $ charge for the number of ladder rungs.....use a new rung for each thing you are doing.

I would also initially do a full download of an empty program and a full reset and clear of the plc.

cheers,
