Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Post by fkoenig on Codesys Control Win 64 3.5.21.0 KNX unaufgelöste Referenzen ^{CODESYS Forge talk (Post)}
Hallo Herr Schwellinger, ich habe in Codesys die KNX Datei nach ETS exportiert und in der ETS eingefügt. Leider lässt sich in der ETS nicht die physikalische Adresse zuweisen. Den Programmier Button wird im KNX Stack betätigt, doch leider wird diese nicht quittiert und die physikalische Adresse zugewiesen. Woran kann dies liegen? Anbei habe ich Ihnen der Device Log. Viele Grüße, Koeni

Post by timvh on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Yes, you are right. I think the help is pretty clear: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_library_development.html It helps you to find errors in the source code of your library if you want to create a library which is using pointers and you want to use your library on 32 and/or 64 bit platforms.

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

Hello We started with the new design of Codesys, through a "CODESYS Control Standard S" license. However, after installing the license, connecting, etc. (without any problems), we cannot get the program into the PLC with entries that we have not seen before. Is there anyone who has also experienced this? Better yet, does anyone have the solution?

Hey, ist es nicht möglich die WagoApp Biblitoheken in zusammenhang mit dem Codesys Control for Win zu nutzen? Wenn ich so eine Bibliothek im Projekt habe, lässt sich das Programm nicht auf das Device Control for Win nicht laden. Entferne ich die Bibliotheke geht es ohne Probleme. Hat damit schon jemand Erfahrung gemacht? Viele Grüße!

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Post by jdjennings1962 on Is there any support for I2C on Raspberry Pi? ^{CODESYS Forge talk (Post)}
Hello, our team is able to use Raspberry Pi on CODESYS, but we purchased two peripherals that utilize I2C and we cannot figure out how to access these devices in CODESYS. But they are working using Python. Does anyone have a suggestion or an existing library that might help support this? Thank you, Jeff

Post by timvh on when going online, stuck on "Syncing file "visuelemsdatetime.tl_datetime.txt" ^{CODESYS Forge talk (Post)}
I don't know the root cause... But what could help to continue when it seems to hang, is stop the CODESYS (communication) Gateway. Go to the Windows SysTray, find the icon for the Gateway and then stop it and start it again. This will interrupt the connection between CODESYS and your controller.

Hey guys, I'm currently developing a Codesys application for an offline Linux device. I can easily set up the license for ONE device using my Windows PC, but what happens if I need to produce a thousand devices? Is there any method to automate license insertion? I have already generated a dpkg installer for deploying the Linux control application to multiple targets. Thanks,

Post by timvh on Codesys SVN ^{CODESYS Forge talk (Post)}
Minimum version is 3.5 SP19 Patch 3. See https://store.codesys.com/en/codesys-git.html But you could ask your PLC vendor if it is possible to program their PLC's which have Runtime version SP16 with development version 3.5 SP19 or higher (should normally be possible, but with Safety PLC's there could be some regulation limitations).
