Edited: Thank you, after further inspection the library is unavailable in the example project for some reason, but using the correct Namespace in my project solved the problem.

Post by bbmussatto on Connetion with Topcon Opus B3 ECO Full display ^{CODESYS Forge talk (Post)}
I have a Topcon Opus B3 ECO Full display and i wanna program it with codesys, but i cant connect it to the display. After creating a new project, i choose the device "Opus B3-B4-B6-3.5.19.50" that is already available in my version of codesys, but i think the problem is that my version of codesys or something else is not the same as the codesys runtime version running on my display. Can anyone tell me how i can see the codesys runtime version on my display? i tried looking in the settings (Daemon > CDS) on the display, but all i see is "N/A" for "Customer Number", "Customer Part Number" and "Customer Serial Number". Can anyone help me make this connection?

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?

Can not activate license on Raspberry pi ^{CODESYS Forge talk (Thread)}
Can not activate license on Raspberry pi
Last updated: 2025-10-08

Post by nicetuxedo on Can not activate license on Raspberry pi ^{CODESYS Forge talk (Post)}
Hello everyone, I'm hoping for some assistance with a license activation issue: a software crash has left my license in a strange state. Here is the sequence of events: I purchased a new license for the Raspberry PI from the official CODESYS web store. I opened the CODESYS and started the online activation process using the ticket number I received. During the activation, the CODESYS software threw an exception and crashed. I was not able to see if the activation completed. After restarting CODESYS, I attempted to run the activation process again with the same ticket number. The License Manager now gives me an error stating that the ticket has already been activated/used. I am now stuck because my installation is not licensed, but the activation server believes my ticket has been consumed. Has anyone encountered this before? Is there a way to have the ticket status reset?

Hello. I'm trying to create a Parameterized Property(CDS V3.5 SP21) to avoid copy-pasting code for processing array elements. I can't seem to get any result. Perhaps I am making a mistake with the syntax. None of the declaration options below are accepted by the compiler. If you know and use them (Parameterized Properties) in your work, please let me know. Thank you in advance. Option 1: PROPERTY <property_name> : <data_type> VAR_INPUT <index_name> : <index_type>; // One or more index parameters are declared here END_VAR</index_type></index_name></data_type></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY Option 2: PROPERTY <property_name> (<index_name> : <index_type>) : <data_type></data_type></index_type></index_name></property_name> GET Code that uses <index_name> to return a value END_GET</index_name> SET Code that uses <index_name> and the implicit variable <property_name> to write a value END_SET</property_name></index_name> END_PROPERTY

Hello, the request is no longer relevant. Thank you. Working with the Main Menu bar via the Alt key is the most effective method. It has absolutely everything there. Calling the context menu via the keyboard is not necessary.

VPLC Section 'Gray-ed Out'

Post by mdetrana on VPLC Section 'Gray-ed Out' ^{CODESYS Forge talk (Post)}
When evaluating Codesys functionality, I found that the VPLC tab under Deploy Control SL > Operation > VPLCs is 'gray-ed out', see attached image. I'm trying to evaluate how my infrastructure will interact with Codesys on a Raspberry Pi 4, so I'm trying to demo running it. I was going through the Codesys tutorial here, and it never shows the tab as grey, so I do not know how to proceed. Let me know if I can get any additional information that can help.
