Post by timvh on when going online, stuck on "Syncing file "visuelemsdatetime.tl_datetime.txt" ^{CODESYS Forge talk (Post)}
I don't know the root cause... But what could help to continue when it seems to hang, is stop the CODESYS (communication) Gateway. Go to the Windows SysTray, find the icon for the Gateway and then stop it and start it again. This will interrupt the connection between CODESYS and your controller.

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

I have managed to change my dynamic visu table colors with the template for each column to dark like my rest of the webvisu background is. How ever the empty table (when not populated) and the table header stays white / gray. Is there same way to modify the colors of header and empty table?

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

Post by stuartjr on Disabling forcing of specific variables ^{CODESYS Forge talk (Post)}
I also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by kimnegw on Codesys offline license batch ^{CODESYS Forge talk (Post)}
Hey guys, I'm currently developing a Codesys application for an offline Linux device. I can easily set up the license for ONE device using my Windows PC, but what happens if I need to produce a thousand devices? Is there any method to automate license insertion? I have already generated a dpkg installer for deploying the Linux control application to multiple targets. Thanks,

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

Post by davidmic on Is it possible to profile builds? ^{CODESYS Forge talk (Post)}
Hi I have a large project (which I can't share here), builds take multiple minutes. My computer is reasonably new (i7-10610U, 32gb ram), and I don't think my company will let me upgrade. Is there any way to profile/inspect the build process? My goal is to figure out why builds take so long, then hopefully I can make them faster.

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
I've been searching through these libraries, syssocket and net base services and they all seem to use the same structure for IP address for the connect function, SOCKADDRESS. At a glance, it doesn't look like that'll work, maybe it's just missing in the documentation somewhere?? I'm wondering if anyone has done it.

Post by jeffersonhui on SysProcessExecuteCommand2 terminate ^{CODESYS Forge talk (Post)}
Hi, I am using the SysProcessExecuteCommand2 function from the SysProcess library to run the candump command in the PLC's Linux environment. However, the candump command stays running indefinitely. If I was running the candump command from a terminal (via PuTTy, etc), that command usually requires Ctrl+C to terminate. Is there a way to terminate a command that is executed with SysProcessExecuteCommand2?

Thank you for your answer. The build > Generate Code start the code of the application but does not modify the compileinfo. I work with .projectarchive to avoid this kind of problem. I would like to have the possibility to modify the compileinfo by myself so I can indicate the losses information.

Post by gseidel on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi bertus, thanks for the additional information. Setting bAbort on a restart is not needed. Calling all FBs starting from the decoder up to checkvelocities with bExecute = FALSE and then giving a new rising edge on bExecute is what should be done. Do you also restart the Interpolator? (I don't think that has anything to do with the issue, but still...) Best regards, Georg

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.

Post by sunfloweeerrry on Edgelogix-rpi-1000-cm4102032 SPI port connection to PiFace I/O Driver in CodeSys. ^{CODESYS Forge talk (Post)}
Hello, I hv a problem. Couldn't solve this for 2 days now. So I'm quite new at CodeSys and I have to use the spi port x30 on the edgelogix rpi 1000. So what I have to do is just 'add device' at the SPI where I hv to pick the 'SPI master' after that I hv to change the parameters according to the edgelogix I did found in the spidev.h but nothing got updated so I 'add device' again where I pick the PiFace I/O Driver and I put my variables at the I/O Mapping, which i put the input startbit at the in part and led at the out part. I want to make the led blink according to my structured text code but somehow the hardware didn't connected with the CodeSys spi port. Nothing happens. Any idea what I have to do?
