Hi there, i also have one doubt related to this topic. Does the maximum cycle time of the F-runtime group be bigger than the time that we use for the F monitoring time, or it doesn't matter ? For example if i have set the maximum cycle time of the F-runtime group to 200 and for my FI/O the F monitoring time is set to 300, can this cause an issue or is it ok ? ------------------------------------------------------------------------------------------ |

Hello BrunoRocalMendes, I'm not sure whether this information is helpful for you, but the "Max. runtime of F-runtime group" can be extended due to, among other things, the communication load (e.g. S7 communication, PROFINET IO communication, PG/OP communication), the processing of higher-priority interrupts and the testing and commissioning functions. You can determine the effect of these factors based on the documentation and configuration of the standard system and add it to the value calculated up to now.
