Hello and welcome to the forum! First of all, you should post this thread in the correct sub-forum (it will likely be moved). Take a look at the datasheet for your cpu. It shows a counter speed of 100kHz. I think the reason you can achieve a frequency higher than the cycle time is because it uses interrupts. |

Hi! Your signal board works up to 200kHz. https://support.industry.siemens.com/cs/ww/en/pv/6ES7223-3AD30-0XB0/td?dl=en You should use HSCs or high-speed counters. https://support.industry.siemens.com/cs/ww/en/view/41127453 https://support.industry.siemens.com/cs/ww/en/view/109742346 |

Thank you for the answer. Sorry for posting the question in the wrong sub-forum. It now makes sense that interruption is used for high frequency. |
