I/O Response Time of Built-in I/O

I/O response time refers to the time from when the input status of inputs is changed until the CPU Unit
completes updating the output status of outputs with the execution results of the user program.
This time varies depending on the timing at which input values change with respect to the task period.
 Minimum I/O Response Time
The I/O response time is minimum when the input values change immediately before the CPU Unit
executes I/O refreshing.
The response time at this time can be calculated as follows.
Minimum I/O response time = Input ON/OFF response time + Input filter time + Task period + Output
ON/OFF response time
