Interrupt Inputs
Section 7-3
Note Enabling interrupts merely returns the interrupts to the status they were in
before they were disabled. If an interrupt was masked before it was disabled, it
will still be masked after it is enabled.
7-3 Interrupt Inputs
7-3-1 Applicable Models
7-3-2 Outline
Contact inputs 0 to 3 to the Customizable Counter Unit can be used for exter-
nal interrupt inputs. These inputs are allocated IR 00000 to IR 00003. The
subroutines corresponding to these inputs are fixed and cannot be change.
Contact inputs 0 to 3 correspond to subroutines 000 to 003.
Note Subroutines 000 to 003 can be used as normal subroutines when the input
interrupts are not being used.
7-3-3 Interrupt Modes
There are two modes that can be used for the input interrupts. Each interrupt
input can be set separately.
Input Interrupt Mode: An interrupt is generated when the input turns ON, OFF,
or both.
Counter Mode: External signals are counted, decrementing from a SV, and an
interrupt is generated when the PV equals 0.
The interrupt mode is set using the INT instruction for each interrupt input.
