7-3-2 Outline
Contact inputs 0 to 3 to the Customizable Counter Unit can be used for external
interrupt inputs. These inputs are allocated IR 00000 to IR 00003. The subrou-
tines corresponding to these inputs are fixed and cannot be change. Contact in-
puts 0 to 3 correspond to subroutines 000 to 003.
Note Subroutines 000 to 003 can be used as normal subroutines when the input inter-
rupts 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.
7-3-4 Interrupt Input Specifications
Input Interrupt Mode
Item Specification
Interrupt condition Input contacts 0 to 3 (IR 00000 to IR 00003) turn ON, OFF, or both (Set in DM 6620.)
