It seems I misunderstood "Toggle color". It's only applicable for the Symbol "FRAME". This part is working fine. See also attached archive.

I did check I cannot see any error log. It is when executing the Reconfigure function that I get an error as return from that function.

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

I am having the same trouble. However, if I change the Login Configuration settings to 'Type: Login using the credentials determined at runtime' then the Connection information continues as 'Connection state: Connecting' and 'Error information: OK'. There is no User Management on the source PLC.

Hey Guys, could you give a explaination of how to change the g_udiMaxPacketSize from 6000 to 100000 and g_udiMaxPayloadSize from 4096 to 80000 ? When I go to the library the parameter is not editable. I would really appreciate it :) Kind Regards

Post by mrkm-dic on UC20-M4000 Redundancy – Application is not automatically synchronized and redundancy breaks after online change ^{CODESYS Forge talk (Post)}
Hello, I am currently testing redundancy using two UC20-M4000 controllers with CODESYS Control SL. The basic redundancy functionality (Active/Passive switching and failover) works, but I am experiencing problems when updating the application. Environment Controller: Weidmüller UC20-M4000 OS: u-OS Runtime: CODESYS Control SL 4.12.1.0-1 Redundancy link: dedicated Ethernet connection between the two controllers Time synchronization: NTP configured, time difference between controllers is about 1–2 seconds Current behavior Application synchronization When I download a modified application to PLC1 (Active controller), the application is not automatically copied to PLC2 (Passive controller). However, when I perform a path swap, the application download to PLC2 starts automatically. My expectation was that the Passive controller would automatically receive the updated application after downloading to the Active controller. Online change When performing an online change, redundancy is lost and the controllers switch to Standalone mode. Typical log messages include: RedundancySynchronize called Redundancy failover itself works correctly. The application boot project exists on both controllers (Application.app and Application.crc). Network interfaces are up and correctly configured. Question Is this behavior expected when updating the application in a redundant UC20-M4000 setup? Should the Passive PLC automatically receive the updated application, or is manual synchronization required? Any advice or recommended configuration for stable redundancy during online change and application download would be greatly appreciated. Thank you.

Were you able to figure out if it is possible to change the Application/Product URI of your server? I am having the same problem.

Post by gseidel on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
Hi SLUCodesys, dwErrorId is a drive specific error number. The drive documentation should be consulted to interpret it. (Note that you should use MC_ReadAxisError to read this error, see https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/MC_ReadAxisError.html. Accessing the internal variable will result in outdated values if the acis error is not mapped by PDO and is not recommended in general.) uiDriveInterfaceError holds errors of the SoftMotion driver for the drive. It is also an internal variable, not intended for direct access. It is intended for logging, the PLC log will contain the drive interface error, consisting of this number and an error text. My recommendation for handling axis errors in the CODESYS application: 1) Use MC_ReadStatus on the axis to find out whether it is in state Errorstop 2) If in Errorstop, there are two possibilities: an error reported by the drive (MC_ReadAxisError) or an error of the SoftMotion function blocks (output MC_ReadStatus.FBErrorOccured). 3) If there is no drive error, you can use SMC_ReadFBError https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/FBError/SMC_ReadFBError.html Best regards, Georg

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

Post by mozed on Connection to device closed ^{CODESYS Forge talk (Post)}
Hello I am using an OpusA3 with version 3.5 SP17 Patch 3 as part of a project. I had no real problem before I encountered a problem that blocked me. The detection of the OpusA3 from Codesys is done correctly. The gateway is well configured and if I ping the gateway or the OpusA3 I receive the response correctly. The problem is that when I try to connect, the Opus screen freezes and a few moments later Codesys displays an error message ("connection to device closed"). I tried to change PC, to update the runtime, to change OpusA3 but the problem remains the same. I'm a little lost knowing that before it worked without problem. I went back to a previous version of the project (where it worked correctly) but the message still appears. Do you have any clues to solve the problem? Sincerely,

Post by tanman19 on How to Use Personal Access Tokens from GitHub with Codesys Git ^{CODESYS Forge talk (Post)}
I am trying to push changes to a GitHub repository. I set up the Git Remote with the correct URL and committed the change. When I push the change it asks for my GitHub credentials which I know are correct, when I type in my username and password it gives me an error: "The provided credentials seem incorrect." So I tried putting in my Person Access token and when I put that in with my username I get this error: "The server request failed and returned a HTTP error code 403: Forbidden". Does anyone know how to correctly use Personal Access Tokens from GitHub with Codesys Git? Does it have to do something with the remote url or my username? Any help or guidance would be appreciated.
