Function Interval timer interrupts
Synchronized pulse control Cannot be used simultaneously.
Interrupt inputs Can be used simultaneously.
Interval timer interrupts Can be used simultaneously.
High-speed counters ---
Interrupt inputs (counter mode) Can be used simultaneously.
Pulse outputs Can be used simultaneously.
Quick-response inputs Can be used simultaneously.
Input time constant See note.
Clock Can be used simultaneously.
Note When inputs 00000 to 00002 are set for use as a high-speed counter, the input
time constants for the relevant inputs are disabled. The input time constants re-
main in effect, however, for the values for refreshing the relevant input relay
area.
Operation Example
Select the input mode and reset
method.
Select the interrupts to be used.
Wire the inputs.
PC Setup (DM 6642)
Create a ladder diagram program.
Input mode: Differential phase input, pulse + direction input, up/down input,
or increment
Reset method: Phase-Z + software reset, or software reset
No interrupts (Read high-speed counter PV, or read range comparison results)
Target value comparison interrupts
Range comparison interrupts
Input numbers: 00000, 00001, 00002
High-speed counter setting
Input mode: Differential phase input, pulse + direction input, up/down input,
or increment
Reset method: Phase-Z + software reset, or software reset
CTBL(63): Register comparison table, start comparison
INI(61): Change PV, start comparison
PRV(62): Read high-speed counter PV, read high-speed counter comparison
status, read range comparison results
SBN(92) and RET(93): Create interrupt subroutine program
(when count-check interrupts are used)
