Hi
This is a high severity warning. This occurs when overlaod of the communication memory access.There is too much access from the application tasks to the PROFIBUS I/O-datainthe shared memory on the CI854 so that the CI854 cannot update the memory in time. The CI854 is not able to read/write process data in time. This status is set when IO copying lock obtained by controller is not released for longer time. Try to distribute the IO to different
execution cycle with different intervals
