Studio 5000 copy bool variables

Hi,

I have a maybe simple question but I don´t know a solution so far..

I have a UDT which contains a lot of BOOL variables. Now i want to copy a few of these BOOL variables to another UDT. How this can be done in Studio5000? The COP instruction don´t work for BOOL.

Thanks for your help!

You just have to do them one at a time with XIC/OTE in ladder, or the assignment operator := in structured text.

Sure this is possible. But this are more than 200 bits and handle them in XIC/OTE is quite a lot of work.
Is there no possiblitiy to copy them with an instruction?

You could do it in excel & paste in...
Or an Add-On instruction.

But perhaps, your structures need looking at to suit what you are trying to do.?
I'm not sure if you can alias a UDT attribute, but that would still involve a lot of work as well,

BOOLs are BOOLs and they just don't behave like INTs or DINTs. Blame the IEC 61131-3 committee.

You might be able to copy the whole UDT to a DINT array, then copy just those sub-elements the contain the BOOL elements into the new UDT. But that's going to require very careful examination of the UDT structure and will malfunction if somebody changes the structure of either UDT in the future.

Doing large numbers of XIC/OTE or assignment operators is tedious, but it's manageable. You could wrap up the code inside an AOI or just call a subroutine at an appropriate time instead of dropping a big chunk of code inside your automation code.

I recently did a project with 90 identical actuators, so I had many programs that relied on brute force code to do the same thing again and again.

One tool that saved me huge amounts of time was Notepad++, a text editor with a lot of very good search/replace and automation tools.

I was able to copy-paste one rung from RSLogix 5000 into NP++, then duplicate it 90 times, increment the array number using the Column Editor feature, then paste it back into RSLogix 5000 as Neutral Text and create 90 new rungs, all while online in RUN mode.

Sure, it was brute force, but once I got the hang of it I could do 90 similar rungs in a minute or two with no errors or typos.

One thing you could do is create a nested UDT of the BOOL tags you need to update in the destination, and use that same UDT in the source.

Then a COP will work.

For a large number of assignments, I generally use Structured Text.
Clean, simple, easy cut & paste.
Much better IMHO then 200 rungs of ladder.
