Overlapping rungs error in CX-Programmer ver.9

7 posts in this topic

Hello, everyone, I'm trying to build simple program in CX-Programmer. When I start the Compile tool it shows me this:

Compiling...
[PLC/Program Name : NewPLC1/NewProgram1]
[Ladder Section Name : Section1]
ERROR: Rung 0 - Overlapping Rungs.
[Ladder Section Name : END]


What is the meaning of this error, what causes it appear and what to do so it does not manifest anymore? Thanks!

This are two pics which represent the program. In fact it takes only one rung (0). I'm wondered  how could rungs overlap, it's only one!

I think CXP is complaining because the SBN instruction immediately follows the SBS instruction (no main program content). Try adding a do nothing rung after the SBS and see what happens.

The problem is there. You can not put all this in the same rung like that.

If you want to regroup many lines in the same rung, put an Always On Flag (CF113) between them and the left bar.
