CPM2A/CPM2C Interrupt Functions
Procedure for Using Interrupt Inputs
Set the interrupt input number.
Wire the inputs.
PC Setup (DM 6628)
Create a ladder diagram program.
The following table shows the relationships between interrupt inputs and the
CPM2A/CPM2C PC's other functions.
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 1. The same input number (from 00003 to 00006) cannot be used for more
than one of the following functions: interrupt inputs, interrupt inputs (counter
mode), or quick-response inputs.
2. When inputs 00003 to 00006 are set for use as interrupt inputs (counter
mode), the input time constants for the relevant inputs are disabled. The in-
put time constants remain in effect, however, for the values for refreshing
the relevant input relay area.
Input numbers: 00003 to 00006 (See note.)
Use as interrupt inputs (interrupt input mode or counter mode)
INT(89): For masking and unmasking interrupt inputs.
SBN(92) and RET(93): For creating interrupt subroutines.
