Interrupt Functions Section 1-4
Count Input Signal (Counter Mode) Wiring Example
PC Setup Parameters Before executing the program, make the following settings in the PC Setup in
PROGRAM mode.
Interrupt Input Settings (DM 6628)
If these settings are not made, interrupts cannot be used in the program.
Input Refresh Word Settings (DM 6630 to DM 6633)
Make these settings when it is necessary to refresh inputs for input interrupt
or counter mode.
Example
If DM 6630 is set to 0100, IR 000 will be refreshed when a signal is received
for interrupt 0.
Note If input refreshing is not used, input signal status within the interrupt routine
will not be reliable. This includes even the status of the interrupt input bit that
activated the interrupt. For example, IR 00000 would not be ON in interrupt
Terminal Corresponding bit address Decrementing mode
B0 (IN0) IR 00000 Pulse inputs (4 inputs max.)
A0 (IN1) IR 00001
B1 (IN2) IR 00002
A1 (IN3) IR 00003
