Post by stiller on OPC UA RPI 4.8.0.0 Status Code / "out of range" ^{CODESYS Forge talk (Post)}
Hello, I have an OPC-UA server with an information model. For many values, there is a defined range (e.g., 0 to 100). If a client enters a value outside this range (e.g., 120), the StatusCode should change to Bad. How can I accomplish this? Any help is appreciated! Thank you in advance. Best regards, Christian Stiller

Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

I have a Codesys environment running and would like to inject code into the running environment at the same time using a code generator with Python via the console. So far I can only start a new Codesys instance with Python, but not access an already running one. How can I access the running Codesys instance?

What does this message mean, in the Errors/Messages box? "[ERROR] MyProjectName: No Offline Help installed" In CDS23, I used to be able to select a system function with the mouse, and press F1. Help and description would popup. How do I get so-called On-line Help installed?

Hello everyone. I am using Codesys and saw in a YouTube video on the Codesys channel (https://www.youtube.com/watch?v=y_l2siXY7dA) that you can create frames and move them with the mouse. However, the video does not show how to do this. Can someone please explain it to me? Thank you very much.

Now, for CODESYS v3.5 SP21 I can no longer find the "OPC UA Information Model Repository" entry to add as a command. In the "Tools" menu it is listed but greyed out, reporting "Plug-in is not available". So how do I add the Plug-in?

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 snhatton on How to write a for loop in ladder? ^{CODESYS Forge talk (Post)}
Hi there, little late to the party, but you could also use the ST block for in-line ST code and implement a for loop as you normally would. ST Block is super handy if you just need a small amount of in-line structured text code without creating a new POU. Hope this helps!
