guess you'll need to use latest CODESYS version to fix this.

Correct, my Device architecture says "None" is this position. A missing config somewhere?

Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Post by davidbo on How to switch between dynamic IP address and dynamic? ^{CODESYS Forge talk (Post)}
I want to make an application with a UI for CODESYS Control for Raspberry Pi MC SL which make it possible to switch between dynamin and fixed IP address and to set the IP address. However I do not know whether that is possible?

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

Hi, same pb for me ! did you find a solution ? (I'm working on 2 raspberry pi ) The same project compiled for 4.8.0.0 runtime with CodeSys 3.5SP20 is working fine on one target, and on the other one, my UAexpert receives the same "BadIdentityTokenInvalid" and none is working on 4.11.0.0 either ... anybody ?

Hello everyone, I need to migrate my existing automation projects from ISaGRAF to CODESYS, and I'm looking for guidance and the best tools and strategies to ensure a smooth transition. Are there any reliable software tools or plugins that can help the conversion? What strategies should I adopt to maintain project integrity? Thank you for the help you can provide! Mat

Nice puzzle for a Saturday afternoon :-). Here my suggestion: VAR sInput : STRING := 'R123'; byChar : BYTE; sOutput : STRING; i: INT; END_VAR sOutput := ''; IF LEN(sInput) = 0 THEN RETURN; END_IF FOR i := 0 TO LEN(sInput) - 1 DO byChar := sInput[i]; sOutput := Concat(sOutput, TO_STRING(byChar)); END_FOR

I don't have a multiplexer so it very weird that it connects with that multiplexer. If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. I will try again with your libraries

Post by wayne-riesterer on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Thanks for your responses. I like to write the leanest possible code that I can because it makes it much easier to read/maintain/debug. OR_ELSE is what I was looking for. I wasn't sure if CodeSys short-circuited evaluation and I didn't realize this operator existed. Thanks!

Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

hi imdatatas, thanks for your suggestion! I added the process execution to be sure. In the meantime I reïnstall Windows but it dind't help directly. Finally I deleted CodeMeter Runtime Server after Codesys installation. Because this Service was not able to start. And it works (for now) :)!

Post by davidking on Error, visualisation property handling, VISU_USEPROPERTYINFO ^{CODESYS Forge talk (Post)}
Solution: Disable VISU_USEPROPERTYINFO define Go to Project → Options (or Project → Properties, depending on your CODESYS version). Find the section called Compiler Defines. Look for the define: nginx Copy Edit VISU_USEPROPERTYINFO Delete it from the list, or uncheck it if it’s a checkbox. Save your changes and try compiling the project again. → This is the right approach if you don’t need property handling for visualization elements.

Good day, I am attempting to use a Waveshare AD/DA precision HAT with RPi 4B+, using Codesys Control for Rpi. The waveshare hat uses SPI. I am successfully using the RPi GPIO (inputs and outputs) but do not know how to access the AD/DA channels. Any help would be appreciated.
