Ah - forgot another question as it may be related to the PLL problem: I am executing a 4ms cycle. I do not call (from what I know) the Ethercat_MAster periodically in my program. The bus cycle task is set to the Ethercat task. I would assume that the master should send 250 frames per second. Yet, the status of the master says it transmits 500 frames per second which would indicate that the master is called twice. Any ideas there?

Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Hi These issues occured using a Raspberry Pi 4. I also repeated the experiment with codesys control for Windows, which results in much lower cycle times. With up to 3 ms, I still think they are fairly high given they should run at 2 ms and don't require complicated kinematics. The effect of higher cycle times for slower movements also prevails.

Hello, this seems to be a known issue, but persistent/retain variables don't seem to work properly on RevPi devices. Is there a workaround to this? All I need is for a few configuration variables to be remembered through power cycle.

Hello, were I have find varaible of SYNC "Cycle Period" , or variable that informs about the start of a new cycle SYNC. I want to use this variable in program code. I need to for communication beetween Mster and slave, and send PDO informations.

Has anyone figured out a way to use the ethercat bus on a beckhoff CX using codesys running on linux? Using ethercat on the native NICs works fine but I get a "packet could not be sent" error when trying to scan the ethercat bus device. Errors and hardware in attached image.

Eigentlich alles ok - sollte gehen - der MDBX wie ist der konfiguriert (also die PDO's) auf Änderung / zyklisch? Wenn du einen CAN Monitor hast, anschließen und schauen was genau auf dem BUS los ist. Also einen CAN Trace machen.
