If so there call frequency is set up in the CPU properties from HWconfig and since a picture says more than a thousands words, I hope the attached one helps. Note that you willhave to download the HWconfig to activate any changes that you made (which requires a CPU restart). Note further that you may have existing logic in your cyclic interrupt OB's which may depend on the currently set call frequency (e.g. pulse counters, PID blocks etc.) and which may now require adjustment. I hope this helps Attachment Cyclic Interrupts.jpg (36 Downloads)
