Control Expert 16.0 Ladder Display

[David-B]

Is there a way to control the appearance of a section of ladder logic. This is my first time using Control Expert or the Modicon 340. The Data contains three parts (Comment, Address, and name) is it possible to limit the display so that only the name and comment get displayed? Is it possible to only display name without the word project (just PE02_1 and not Project.PE02_1). Can the comment be multi-lines of say 15 characters on each line?

Have you considered using Function block diagram instead of Ladder. Ladder has always been a bit 'clunky'

For digital logic it is easy to read and comment

Here is an example of a self resetting latched alarm - this would probably involve multiple rungs in ladder

And for analog calculations I think it is easy to trace how a calculation is performed

If you go to Tools> Project Settings> Program > Languages> LD> Mixed Display, you can customize how many lines are available for comments, the symbol, and the address:

Is your section inside of a DFB (AOI)? That's the only place I know of where you need to reference variables external to the DFB as PROJECT.x.y.z If you don't like that, you'll have to add an input or in/out pin to your DFB and insert the variable that way.

I like Function Block because I can see more of the logic on the screen than I can with ladder. It is also faster to code than ladder. I only use ladder with Rockwell because Rockwell doesn't have a complete instruction set in all the different languages. Control Expert  is just a superior programming package.

Thank You! it did not occur to me to set the number of lines to zero.

I couldn't disagree with your opinions more. I am 70 years old and have been writing PLC code for over 35 years. Function block programming has been around for a long time yet 80% of all PLC programmers still prefer Ladder logic. So far my experience with Control Expert has been fairly poor, although I'll admit I'm going thru a bit of a learning curve. If Control Expert were so great it would be the popular choice for companies using PLC equipment, but its not.

you right!
