Hi! I tried to start Codesys V3.5 SP11 program and this error message popped up (see attachment). Program worked fine last week. I tried to uninstall and then reinstall the program but it did not help. If I choose Ignore or Retry options the program works expect the UI is missing. Any ideas how to fix this?

Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

You can change the node id by adding the following to /etc/CODESYSControl.cfg: [CmpOPCUAProviderIecVarAccess] CustomNodeName=MyPLC123 Then restart the runtime and the new Node name will appear with the connection. I don't know if it's possible to remove the |var| from the name. I hope this helps!

I have a video demonstrating the procedure to install the runtime on a linux device. https://youtu.be/rj0dOhgnGjs?si=OJoA-kgc1saxIweR This demonstration shows how to install the runtime on a X86 based controller, it should be the same for an ARM based device, but you'll need to install the add-in for Codesys control for Linux ARM SL (or the 64 bit add-in.)

Hello, I'm coming to you today because I'm trying to make the baudrate and the slave number dynamic. I've tried the "updateComPortSettings" method on the slave device but it doesn't work and gives the "Modbus_COM_Port" an error. Can you tell me how you got this method to work? Thanks in advance for your help jérémy

To display the current time, you’ll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Here’s an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format “HH:MM:SSuno online".

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

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.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
