Input Interrupts In Counter Mode
The four built-in interrupt inputs in the 3G3MV-P10CDT Unit can be used in
counter mode as inputs of up to 2 kHz. These inputs can be used as either
incrementing counters or decrementing counters, triggering an interrupt (i.e.,
executing an interrupt subroutine) when the count matches the set value.
For more details please refer to Programming Manual W353
Procedure for Using Interrupt Inputs in Counter Mode
Set the interrupt number.
Select either incrementing or
decrementing count.
Wire the inputs.
Input numbers: 00003 or 00004
PLC Setup (DM 6628)
1. Use as interrupt input (interrupt input
mode or counter mode)
Create a ladder diagram program.
INI(61): Change counter PV
INT(89): Refresh SV*
(PRV(62): Read counter PV
SBN(92) and RET(93): For creating interrupt subroutines.*
*Used only for count-up interrupts.
