Post by bjarne-pagaard on Global Variables ^{CODESYS Forge talk (Post)}
Old thread, I know - but it still has good answers. I would like to add a bit of info to it, as I was having a problem that lead me to this thread, but didn't give an exact answer. I am porting a project to a different PLC architecture. (Wago PFC300) A GVL named 'GVL' in the POUs section of my project was shadowed by a PLC-specific library in the Application->Library Manager. So all the existing references in the device specific code to 'GVL.something' would not resolve. Right-clicking the GVL in the code and 'Go to definition' would point me to the library in the Application Library Manager. All I had to do from there, was right-click the library, and set the property 'Only allow qualified access to all identifiers' in the library.

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff
