Interrupt
Input Unit
-
Features
1. Constant high-speed processing
The interrupt program is executed immediately
after accepting an interrupt input so that high-speed processing
can be performed at a constant timing, regard-less of CPU's
scanning speed.
-
2. High-speed response
Input delay (OFF <--> ON) : 0.2 ms or less
Interrupt processing delay : 0.35 ms or less
3. 8 interrupt programs available with a
single unit
4. The conditions for issuing an interrupt
signal (rise/fall) can be modified for every input
5. Can be used as a general input unit
The Interrupt Unit can also be used as a general
input unit when it is not used for interrupt operation.
