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

Post by kevinrn on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
Hello community, I just want to inform you about our plans and the current status of automating the build process for CODESYS libraries. So it might be helpful for some people who are in the same situation. Background story: I am a software engineer at powerIO GmbH, normally I use high level languages for the products we develop and offer. Sometimes I work with my team on CODESYS libraries, which can also be found in the CODESYS store. Most of the time I spend with them on architecture tasks and tasks that are not directly related to our products. Every time I see the manual processes for releasing a library etc., I am very surprised about this time intensive process. Current situation: I know there has been a scripting interface for years. CODESYS Git was released a few years ago, but the scripting interface was only released a few months (weeks?) ago. We developed a pseudo-automated solution a few months ago, but it was all very hacky. So now there is a better Git implementation and also more modularization and installation options. For example, the CODESYS installer has a full CLI, which makes it very convenient to install CODESYS installations headless. Plans: I think it's the right time to develop a better automation solution. Most of our software projects are hosted on Github and we use Github actions very intensively for other software projects. Therefore, we have decided to use Github for our CODESYS library projects as well. Following tasks should be implemented in automation for CI/CD tasks: - Automated setup of CODESYS installation (Already released: https://github.com/marketplace/actions/setup-codesys-installation) - Checkout CODESYS libraries - Execute tests scripts - Sign CODESYS libraries - Extract Library documentation - Create CODESYS package - Sign CODESYS package Side Note: - This is mainly a side project, and we do not provide support for the CI/CD part. - This topic is here to help and also to get help from other software engineers. - This project and idea is not prioritized as I am currently the only one working on it and I hope it will help us and also others and increase productivity. - We are putting this out there as an organization, but priorities can change quickly and the CI/CD tasks I am developing are mostly done in my spare time. So please don't expect this to happen in a short time or even be fully completed. I would be very happy if some ppl will join the development process and might be open to discuss some technical details for this. I hope this topic is not to off-topic, but I think the CI/CD part is very important today and it can increase a lot of quality and push productivity. Thanks :)

I have library projects which has few function blocks. I have assigned security to each FB. I want to protect them and user can only be able to use it without viewing the code inside. What kind of file I should send to user? Is it compiled library file?

Post by correo0269 on Problems with Raspberry Pi - IoDrvGPIO library ^{CODESYS Forge talk (Post)}
I am trying to create a new proyect using the Raspberry Pi 4.11.0.0 package with Codesys 3.5 SP20, I am able to communicate with the Raspberry and start the runtime application but when I create a new proyect I have these errors. When opening the library manager of the proyect the library of the IoDrvGPIO is used so I dont really know whats happening.

The SM3_Drive_ETC_Beckhoff_EL70xx library has descriptors for the EL7031, EL7041 and EL7047 but not the EL7037? Is there another library that has the one I need?

Post by abrarsk on Download libraries of old versions ^{CODESYS Forge talk (Post)}
You can download the missing libraries by clicking on the "Download Missing Libraries" button. However, if you were unaware of this and accidentally downloaded the latest version of the library from the Library Repository, you may need to uninstall it first to avoid conflicts.

In fact, specifying to use SM3_Basic library in version 4.14 fixes the issues, choosing 4.16 raises the same issues. (Library Manager > Place Holder > Double click on SM3_Basic > Show all versions)
