Maybe also good to know that you could use the CODESYS installer to switch between gateways. - open the CODESYS installer - Select the (hamburger) menu - Select Settings - Select Services Then select the Gateway you would like to use.

Update: it seems that the license is detected by CODESYS on my computer but not detected by the runtime on my device. I'm using Codesys control for raspberry pi in the latest version 4.11.0.0 Is there something to do to correct this ?

Seems that the Wago Target does not support the licensing. Either use PFC200 SL from CODESYS Store or ask the Wago support for help.

sorry I missed to say how to do this just update the runtime. (extract latest debian package out of the CODESYS package) but 8n this case an update all to the latest version including CODESYS is probably the easiest option now.

Maybe check: - The library manager, are you maybe missing some libraries - Tools - CODESYS installer: update the CODESYS Visualization and Visualization support - Project - Project environment: maybe you need to update the visualization profile

Is it possible to do non-formal invocation of function blocks in CODESYS? I get an error when I try, see the attached pic. Also attached a pic from IEC 61131-3 describing non-formal invocations.

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

Compared to the Codesys 3.5 SP19 Patch 1 version, the context menu on a Trace object no longer works. So I can no longer run the Downloader Trace command. Do any options need to be enabled with the new version? Best regards Roberto Caponi

Hi all, is it possible to use object instances that are not instantiated by codesys itself, e.g. have been defined in UA-Modeler ? When I browse the plc with UA-Expert I see those instances, but I have not seen information in codesys or the web if these are writable in codesys. So far, I am under the impression, that it is not possible, but would like to hear from others. Also, is it correct, that it is not possible to create references inside codesys ? Thanks in advance and kr

hello. After installing the latest version of codesys (3.5.20) from codesys installer, I had a problem. All my devices disappeared. Both PLCs and IO modules and network devices disappeared from my list. I browsed through the Windows files and I can find them in the programdata/codesys/devices folder. The files remain there, but they are not available within codesys (same error in all installed versions) which in this case are 3.5.16 and 3.5.19. Does anyone know how I can reimport or resynchronize my devices folder again? Thanks

CODESYS IDE is not a modern IDE. Its interface is ugly, its operation is not user-friendly, its functions are lacking, its feedback is slow, and its development is not good enough. In fact, CODESYS is a helpless choice under the current situation. But this situation will not last long. For example, SIMATIC AX is a strong competitor of CODESYS, which is more open and inclusive.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
