Post by davidbo on i2c How does CODESYS handle exception or error messages. ^{CODESYS Forge talk (Post)}
For Raspberry Pi I have made a python script which regularly read a bulk of data over the ic2 from a device. Sometimes I get an Exception an IOError. I assume similar things can happen in CODESYS. So how does CODESYS handle that? Can I get any info about such an event?

Hello, I think you can try to change the Connection from Multicast to Point to Point. Please also make sure your windows firewall is allowing the correct UDP ports inbound for ethernet IP. You might also need to increase the RPI, so it times out slower.

Hi I need to update by software some structures in my datasource, i found this example: https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_update_data_interface.html it seems that because i use complex variable structure i need to use UseDataExpanding() instead of use data, the question is how to get an instance of IDatasourcesMgr3 i have the global variable g_Datasources is instantiated automatically

Here I have attached the task monitor data. What is very weird is that I am using MC__MoveDirectAbsolute FB, when I choose Vel/ACC/Jerk Factor to 1.0 it run fine. It ran 10 hours without the issue. But I get the error randomly when I use factor as 0.5

Post by kaotic2499 on Upgraded Raspberry 2b to Raspberry 5, Trends Broken? ^{CODESYS Forge talk (Post)}
There is currently a bug with the Raspberry Pi 64 SL where it is unable to Trend Global Retain or PersistantVars. The work around is to use standard Global Variables for Trend Data. This will be patched by Codesys in the near future reference "VIS-6170"

Post by jinlee on Symbol Configuration ^{CODESYS Forge talk (Post)}
Hi guys, I am working on an old project which using Codesys v2.3 talks to Beijer's screen TA150 (IX-Developer 2.20). Codesys v2.3 is different with 3.5 and Ecockpit. I know how to import the symbols from PLC to HMI for Codesys 3.5 and Ecockpit. However, I do not know how to do it on Codesys v2.3. I know that I can make excel sheet to import and export from the HMI and add whatever I want based on PLC. However, is there any quicker way of doing this? So that I can directly import the symbols (tags) from PLC (Codesys 2.3 to HMI).

Think just add some CANopen Slaves and end resistors - then it will work ;-)

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.

I think what you want is a declaration period function for the page, but unfortunately CODESYS does not have it.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi, Is there a process to restore Persistence Manager files? I have backups of persistence variables used in a machine that is currently operating and tuned and all set points adjusted. There are about 500 persistence variables, they are building another identical machine. I would like to use Persistence Manager files from the first machine in the second also. I have tried copying the files and replacing them on the new RPI but then the Persistence Manager gets errors and then they are all reset to 0 etc I have tried adjusting the times to match. Instead of replacing whole file, I tried just changing the contents inside the file, but still does not work. I may be missing something here, but surely there must be a way to load a backup. Thanks!
