Post by pietrobalint on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi micik, I am not sure I am using well the code, because I checked the directory and there is no retains.ret file. Now I deleted the code from my project and the values are still works as persistant variables after ssh reboot it seems to me they retain as their previous value. So I am a bit confused, maybe 4.12.0.0 Raspberry Pi SL solved the persitent variable problem...

Post by respl on IFM EXOR Network variable Error ^{CODESYS Forge talk (Post)}
We are connected IFM CR711S to Exor EX710. We are exchanging data using network variables. Both devices are configured on same project so no need to use file source. When tested application it works fine. But after 3 months same application not working. We are able to send data from CR711 to EX710 but data from Ex710 to CR711s works only for one scan when we cold reset CR 711S. Can somebody help to find out error.

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by marciohogenelst on stablish CAN communication through the PC's USB port ^{CODESYS Forge talk (Post)}
I'm using Codesys v3.21SP4 on my PC via ControlWin to establish CAN communication through the PC's USB port. The software works fine. The CAN/USB converter works fine and is validated. However, there is no communication. Which folder and file should be modified to allow the CAN/USB converter to work and thus achieve the connection? Converter used: PCAN-View Information not yet processed: Access the folder: C:\Program Files (x86)\3S CODESYS\GatewayPLC\CODESYSControl.cfg Uncomment the line: Component.5=CmpPCANBasicDrv Any help would be appreciated.

Post by ouzago on ERROR C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
When I created a new project in CODESYS using the "Standard Project" template and then added a Visualization, I was receiving the C0138 error during compilation. This issue persisted even with a new, completely empty project. A Quick and Effective Solution (My Method): After many attempts, I solved the problem as follows: From the File -> New Project menu, I selected the "HMI Project" template directly, instead of the "Standard Project" template. After creating the project with this template, I added my POUs, Tasks, and programs (e.g., Ladder, ST). Using this method, the project compiled successfully without any errors. So, my question is: are there any other solutions besides this method?

Post by spice on WebVisu Recipe Save/Load ^{CODESYS Forge talk (Post)}
I'm currently reworking the controls on a cnc press brake and wanted to load various recipes as programs to run. I'm using a 2d array of REALs to store the X and Y coordinates as well as some other program parameters in a recipe. I'd like to store all of the recipes on a computer used as the HMI that way the text files can be edited and uploaded offline. I'm using Automation Directs P2CDS-622 Can this be done through webvisu? If not would a license for Codesys HMI SL on the computer allow me to accomplish this? I've attached the Project File Thanks, Spice

no need to activate application composer. It is part of the licensefree part.
