Input Interrupt Mode
Counter Mode
When the number of external signals counted at high speed reaches a specified number of counts, the regular program shuts down, and
the interrupt processing program is executed at fixed counts. The count can be set between 0 and 65535.
J QUICK-RESPONSE INPUTS
Quick-response inputs can detect input signals with a pulse width
as short as 0.2 ms regardless of their timing during the scan
cycle. Quick-response inputs and interrupt inputs use the same
input terminals.
If an input interrupt occurs, the regu-
lar program shuts down irrelevant of
the cycle time, and the interrupt pro-
cessing program is executed im-
mediately.

Application Example:
Calculating the Number of Chips
The metal sensor counts the number of
parts that have passed. Steady counting
can be achieved even when the input-ON
time is short.
