Hello, I encountered similar problems, and it appears they were linked to certain add-ons. Resolving this issue turned out to be quite complex. However, we managed to find a solution by downgrading both the "CODESYS Communication" and "CODESYS Recipes" components via the CODESYS Installer, accessible under the "Tools" section.

I'm searching a way to print several projects to PDF, in order to correct student exercises. I'm able to open the printing dialog box using system.commands["print", "print"].execute(). But I can't find the prompt names in order to complete the printing with the dialogs Do you have any way to do that?

Post by hanoues on Holding brake release ^{CODESYS Forge talk (Post)}
I've tried using the SMC3_BrakeControl function block to control the brake, but unfortunately, it's not functioning as expected. Despite setting the appropriate parameters and inputs, the brake control does not operate correctly. Any insights or suggestions on resolving this issue would be greatly appreciated. STATE_MANUAL.UNLOCK_BRAKE: IF Button_release_brake THEN GVL.drum1_Control_Brake:=TRUE; FBA.T11_ContBrake.bExecute := TRUE; GVL.manual_state := STATE_MANUAL.WAIT_FOR_BRAKE_RELEASE; END_IF STATE_MANUAL.WAIT_FOR_BRAKE_RELEASE: IF FBA.T11_ContBrake.bDone THEN FBA.T11_ContBrake.bExecute := FALSE; GVL.manual_state := STATE_MANUAL.WAIT_START_BUTTON; END_IF

I have some errors as you can see in the picture when i build the project. I have not been able to trace back to the error and i have no idea where to look at to fix this issue. What is GVL_Io? Is it related to some library?

Hello Jusito, Can you share your final code, please ? I tried to implement a similar feature (going online, doing the reset and the start). But I get a timeout on the reset/start when I'm testing the script. If you got something working, I would appreciate to see it.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger How does the persistent manager files work on v20? I would Like to upgrade my v19 as I'm still having issues. Sometimes if there is a power cut CodeSys won't load the Persistence Manager files and I have to redownload to the PLC and then copy my backup persistent files and then start the application. I hope it's a lot more robust in v20

Hello, I'm using th IDE Combivis studio 6 (codesys based) and I get an error message when I use IO-link. "The license is missing or invalid. The API is running in demo mode." However the package Manager indicates that no licence is required. It used to work, it seems that the free package has become a paying one. Can Codeys confirm this? BR

There are examples installed when you install codesys. they are located in C:\Program Files\CODESYS 3.5.19.50\CODESYS\CODESYS SoftMotion\Examples The examples won't be specific to your drive, though you haven't specified the exact drive. After you add the device to the ethercat master you can click on it and set pdo etc

Hi Reinier, I'm wondering if you managed to get this FB to work? I was just trying it, and found it not to work, I get an EMCY message in the CodeSys program under the Device Status, but the FB doesn't pick up any EMCY messages from the Bus. Cheers.

Post by timvh on Textfield display problem ^{CODESYS Forge talk (Post)}
Did you test this with the latest version of the CODESYS Visualization add-on? Something that you might want to test is if it works better when you disable the "Support client animation and overlay of native elements". Double-click on the VisualizationManager in your project to find this setting.

Codesys - SMC_ERROR SMC_CGR_INVALID_POSPERIOD - Invalid modulo period less than or equal to zero or greater than half the bus bandwidth. Has anyone seen this error and actually understands what it means and how to get rid of it? I tried to work around it by reducing the number of increments on the drive but then the drive itself starts throwing errors.
