Does anyone know a C# read I/O commands will take place in which step of PLC cycle?
Or totally does it affect on PLC's CPU scan cycle time?

Hi Sara J, when using C# for reading I/Os, I assume you are using S7 communication like is done by Snap7 (respectively Sharp7). In this case, the communication is asynchronous to the scan cycle. Like other communications, it has effect on the scan cycle of the PLC. But depending on the amount of data, you might not recognize this. Kind regards |
