Post by andrej on Threads and TID created by CODESYSControl Win V3 ^{CODESYS Forge talk (Post)}
Hi all, for a deeper understanding of the Codesys RTE - I created a simple application with 3 IEC tasks (Ta,Tb,Tc) each with different priorities, and different cycle times. The application runs on Windows 10 in the Soft PLC CODESYS Control Win V3. If my understanding is correct, the RTE i.e. the Process CodesysControlService should spawn 3 threads (Th_a,Th_b,Th_c) which are executed with the defined cycle times, the priority of the threads should reflect the priority of the task set in the Codesys IDE. Does somebody have an idea, how I could identify the respective threads in Windows? Kind regards Andrej

Post by buczekj on About CPU Loading ^{CODESYS Forge talk (Post)}
This is a phenomenon that I have seen myself and with others. Texas instruments wrote an application note with this same issue. They noted with Codesys 3.5.19.10, that selecting CPU 1 as the EtherCAT task showed CPU spiking improvements over the performance of cores 0, 2, and 3. It appears to be linked to EtherCAT, are you configuring for use with distributed clocks? If so, I recommend choosing the 'Based on Input Reference' option. I have found it to reduce the CPU usage spike maximum slightly (see attached). See link to TI (also attached in case link breaks) https://www.ti.com/lit/an/spradh0/spradh0.pdf?ts=1723546111357

Post by edson-bueno on SysProcess Execute Command unable to run commands with special characters ^{CODESYS Forge talk (Post)}
Hi, I found the same issue, and I fixed with this steps: 1st go to codesys .cfg file. sudo nano CODESYSControl.cfg Then insert this: [SysProcess] BasePriority=Realtime Command=AllowAll Now we need to grant codesys root rights on Linux. Step 1: Create or edit the systemd override configuration: sudo systemctl edit codesyscontrol In the editor that opens, insert: [Service] User=root Save and exit: Press Ctrl+O to save Press Ctrl+X to exit Step 2: Reload systemd and reboot To apply the override: sudo systemctl daemon-reexec sudo systemctl daemon-reload sudo reboot Step 3: Confirm CODESYS is running as root After reboot, open the terminal and run: ps aux | grep codesyscontrol You should see something like: root 1234 ... /opt/codesys/bin/codesyscontrol.bin ... If instead it shows admin or another user, the override was not applied correctly. Step 4: (Optional) Confirm from within CODESYS In your CODESYS project, insert this test code to run the Linux command whoami: Make sure the lib SysProcessImplementation, SysTypes, and CmpErrors is on the project. VAR sCommand : STRING := '/usr/bin/whoami'; sOutput : STRING(255); refCommand : REFERENCE TO STRING; refOutput : REFERENCE TO STRING; resultCmd : UDINT; END_VAR refCommand REF= sCommand; refOutput REF= sOutput; SysProcessExecuteCommand2( pszCommand := refCommand, pszStdOut := refOutput, udiStdOutLen := SIZEOF(sOutput), pResult := ADR(resultCmd) ); Notes & Warnings This method gives full system access to the CODESYS runtime — do not expose this system to the public network without protection. Do not use sudo in commands inside CODESYS when the runtime is already running as root. @tomas111, in case you want to read the temperatur, use this command: sCommand:STRING:='/usr/bin/vcgencmd measure_temp';
