I/O Response Time
Interrupt Input Pulse Width
The interrupt return time is 0.04 ms.
Note 1. If there are several elements that can cause interrupts or if the interrupt peri-
od is shorted than the average interrupt processing time, the interrupt sub-
routine will be executed and the main program will not be executed. This will
cause the cycle monitoring time to be exceeded and an FALS 9F error will be
generated, stopping PC operation.
2. The maximum interrupt program execution time is contained in SR 262 and
SR 263.
The pulse width input to Interrupt Input Units must be set to within the conditions
shown in the following diagram.
0.2 ms min.
ON time: 0.2 ms min.
OFF time: 0.5 ms min.
0.5 ms min.
