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?
