[Highlighted line in GX Developer]

It's a while since I came across 'yellow' code.

In my case it was incomplete lines. (no OUT instruction and such)

 

I looked at the ladder in 'list' and could see it was scrambled gobbledy gook.

I deleted the incomplete ladder and all was well.

 

Change the view to 'list' and see what you have

 

Thank you, this is exactly what I was looking for!

I am now able to edit these rungs and find out the problem.

 

Thanks again!

Usually it is code that cannot be converted to the plc you are using - or corrupt lines.

You usually have to delete this part to get rid of the yellow

So there is no way to view it?

Thank you for your reply.

Working in GX Developer Version 8.107M, some of the code that I have been working with seems to be hidden.  It appears that the lines turn highlighter yellow, keeping me from viewing code.  I've looked into this and cannot find a solution.  Does anyone know how to expand the code?

Thank you.
