7-3-3 I/O Response Time
The I/O response time is the time it takes after an input signal has been
received (i.e., after an input bit has turned ON) for the PC to check and pro-
cess the information and to output a control signal (i.e., to output the result of
the processing to an output bit). The I/O response time varies according to the
timing and processing conditions.
The minimum and maximum I/O response times are shown here, using the
following program as an example.
