11.2 External Interrupt
11.2.1 Overview
The device uses X000-X007 inputs to execute the interrupt subprogram.
As external inputs can be processed regardless of the calculation cycle of the PLC, external interrupts can
be used for high-speed control and short pulse acquisition.

Note: When M8050 to M8052 are ON, the corresponding interrupt events are disabled.
Pay attention to the following tips.
●
Prohibited reuse of input numbers
• The number of the input relay as an interrupt pointer cannot be the same as the ID of any application instruction
within the same input range, for example, the high-speed counter instruction, pulse capture instruction, and pulse
density instruction.
●
Automatic input lter adjustment
• When the input interrupt pointer I□0□ is specied, the input lter of the input relay will be automatically used for
high-speed reading. Therefore, you do not need to use the REFF instruction and special register D8020 (input
lter adjustment) to change the lter adjustment.
• In addition, the input lter of the input relay not used as an external signal input interrupt pointer remains effective
for 10 ms (initial value).
