Post by ulad on SPI Communication ^{CODESYS Forge talk (Post)}
Hello. I created a project that uses SPI. This project is working well. I can see with an oscilloscope that the SPI pins are actually changing. But when I resave this project in the IDE and open it later in the system, I see a constant error. What do I need to fix? What am I doing wrong? Thank you.

Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
I stopped the simulation and tried to rebuild. "Cloned Task0.task0. Priority already in use" error was shown after rebuilding. I used Build-Clean All option and rebuilt again. Now the logic started working. But I am not still sure what caused the error in first place. If somebody knows about this error, please enlighten me. Thanks svn

Post by dhumphries on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Function blocks in a SFC are executed left to right, top to bottom, instructions in ST are executed from left to right top to bottom as well. I think you are asking about the execution of POUs although you use the name function block, I believe POUs are executed in the order they are shown under the main task.

Post by patrick on Version 3.5.19.40 probleme bei FUN mit _to_ im Name ^{CODESYS Forge talk (Post)}
Ich bin leider auch über den Fehler gestolpert, aber selbst in Version 3.5.19.50 ist dieser noch enthalten. Bis 3.5.19.20 kann ich meine Programme noch nutzen. Ab 3.5.19.30 ist der Fehler anscheinend vorhanden. Ich habe leider auch schon einen Haufen Programme mit meiner Library erstellt, somit wäre ein umbenennen nur mit sehr viel aufwand möglich.

Just verified the behaviour. Still is the same. It should be attached here. But I also tried the DCF-file with the axis in the lab with the real drive: The MC_Power block never goes out of busy. Had not time to investigate further, though.

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Post by lgeertsema on Checkbox font color in visualization style ^{CODESYS Forge talk (Post)}
Hello, I'm having a similar issue with buttons. I want to be able to set the default color and transparency of a button. I've tried a lot of different iterations like KNewman, but to no avail. Has there been some documentation released since KNewman posted this, or is the style editor still as undocumented as ever?

Post by scarter on Import/Export PLCOpen xml Task Configuration ^{CODESYS Forge talk (Post)}
I'm Having the same issue. If I highlight PLC Logic and import it erases everything else and replaces the Task config. If I highlight the Application I get the same result. Simple manual fix is click and drag the task config onto the origional Application, and delete the second one. Easy fix but not the expected result of importing task config.

I have library projects which has few function blocks. I have assigned security to each FB. I want to protect them and user can only be able to use it without viewing the code inside. What kind of file I should send to user? Is it compiled library file?

Post by masmith1553 on SDO generation ^{CODESYS Forge talk (Post)}
If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Post by wiresplus on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Hello, Depends on the architecture of your PLC. If the PLC is a PC-based item with a normal desktop environment, then you probably can. I find it simpler to install an IIoT Router in the panel, and use an encripted VPN to link to my office PC / Laptop on demand.

Post by thomas-moba on "sudo"-Befehle über die Funktion "SysProcessExecuteCommand2" ^{CODESYS Forge talk (Post)}
Wir haben jetzt so ziemlich alles probiert. Ohne sudo mit sudo, den Aufruf in ein Script gepackt (.sh und .py) und sogar ein eigenes kleines Linux-Programm geschrieben, weil wir vermuteten das der sudo-Befehl nicht im Klartext ausgeführt werden darf. Es funktioniert einfach nicht. Daher dir Frage: muss die codesyscontrol als root ausgeführt werden? Momentan wird sie als user ausgeführt.

If my application does some kind of violation which makes it cast an exception it will trigger my real watchdog which results in a reboot. Unfortunately the log it seems only shows the boot sequence. Is it possible to see what happen before reboot?

I'll have a look at this, thanks. Do you maybe know why the C-integration doesn't work? I'm just curious because it was still some effort to create all these files. Ending up with a meaningless error feels very unsatisfying to me...

Seit dem Update auf die Version V3.5 SP19 Patch 5 von der Version V3.5 SP17 haben wir das folgende Problem. Wir möchten von einem Gerät die Lizenz speichern. Damit wir nach einem neuen Raspberry Pi image die gleiche Lizenz für dieses Gerät brauchen können. Die Lizenz ist Geräte spezifisch so viel ich weiss. Bei unseren Geräten bei den Kunden hat es nicht immer eine Internetverbindung.

Finally this solved my issue: https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/, and the official documentation https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager . Add the media folder to the PlaceholderFilePath. Like this: PlaceholderFilePath.2=/media/pi, $usb$ PlaceholderFilePath.2.View=1 PlaceholderFilePath.2.Volatile=1

Assume I have a rectangle named rec1 from which I want to use the coordinates of the upper left corner. Is there a way to links these X and Y values from the properties to an integer defined in the main program? Note that I just want to use them and not change any of these coordinates in the program.

My experience is that opening pdf file is very dependent on which browser is used. I have tried a couple of them and only Mozilla Firefox has opened file correctly in same screen. All other browsers face some issues. Therefor I had to flip my pdf to txt which has not been nice solution.

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

I have found a similar topic but tried to run it in C3.5.16 and the visualization crashed. https://forge.codesys.com/forge/talk/Engineering/thread/8be0f6f14a/ My question is what is the easiest way to run a dialog from ST, as we need an external device to open the dialog so we cannot use the button on the display itself.
