Find ALL unused elements

[Ausman]

Hi all,

In Visilogic I am requesting that in Edit/FindElements we get the ability to find all unused elements in one search.  In complex programs during development I can't be alone in losing track of things that have been tried, need modification and eventually turn into unused elements.  Although this "shouldn't" happen, in the real world it does.  Pencil work can only do so much!

I wouldn't care if it took a little while to run through a simple loop covering everything it finds supposedly used within all the operand tables, as it would save vastly more time than going through thousands of elements manually!

cheers,

Aus

Which elements are not being found under View / Operands Not Referenced in Project?

[Ausman]

HI Flex,

I have always found Operands Not Referenced to bring up things that are actually used in the program, and therefore don't use it.  See attached pic. 

But, right click on an operand in the list and do a Find "X" and it will correctly identify those that aren't used at all, but only one at a time.  I would like one click to find all of them.

cheers,

Aus

Well, that's frightening. I use that frequently and had no idea I was at risk of removing an operand that was in use. Not horrible, I suppose, since it's only removing the description. It sounds like there may be a bug in that routine.

Ahh....but Flex, check the next jpg out.

To demonstrate, I deleted the description of MB0 and in doing so it also dropped the Use tick.    It now doesn't appear in the Operands not Referenced box, but it is still in use in the program.  You are right, there is a bug, I've never thought of complaining because I just resigned myself to never use it!

Mostly I keep track of things, but occasionally during further mods I come across an element that doesn't make sense, then discover it isn't in use and was part of a previous method of doing something.  These are the elements I want to completely see in one overview that will help me clean things up.

So send the bug with the project to the support.

Hi Saragini,

I cannot send the projects as they are proprietary and am exploring the issue at present to find a definite cause.   I made a simple project to test things and it all worked fine.

In the projects where the problem is evident, it seems to be related to items on HMI screens where addressing/referencing has been changed to a new location and the old one reused for another aspect.  But I have run out of time for now so will advise further when I can spend a bit more time on it and hopefully pin it down.

cheers,

Aus
