At the rising or falling edge of the input signal, the CPU Unit's cyclic program is interrupted and the corre-
sponding I/O interrupt task (task number 140 to 143) is executed. The response time (i.e., the time from the
input condition being satisfied until execution of the interrupt task) is 93 s min.
The number of rising or falling edges of the input signal are counted incrementally or decrementally, and
when the count has been reached, the corresponding interrupt task (task number 140 to 143) is executed.
The input response frequency is 1 kHz.
Signals less than the cycle time (30 s min.) can be treated as ON signals for one cycle.
