CPM2A/CPM2C High-speed Counters
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.
48
Function
Synchronized pulse control
Interrupt inputs
Interval timer interrupts
High-speed counters
Interrupt inputs (counter mode)
Pulse outputs
Quick-response inputs
Input time constant
Clock
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.
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)
