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
