Input Interrupts
Section 7-3
The EI(694) instruction does not enable all interrupts. If an interrupt was
masked before all interrupts were disabled, that interrupt will still be masked
after the prohibition on all interrupts is cleared.

Overview of the Input Interrupt Function
Contact inputs 0 to 3 in the Motion Control Modules can be used for external
interrupt inputs. These inputs correspond to CIO 0000.00 to CIO 0000.03.
The interrupt tasks corresponding to these inputs are fixed and cannot be
changed. Contact inputs 0 to 3 call interrupt tasks 000 to 003, respectively.

The interrupt tasks corresponding to these inputs are fixed and cannot be

Note
If the input interrupts are not being used, interrupt tasks 000 to 003 can be
used as interrupt tasks for other interrupt functions.

Interrupt Modes
There are two modes that can be used for the input interrupts. Each of the
four interrupt inputs can be set to either of these modes.
four interrupt inputs can be set to either of these modes.
• Input Interrupt Mode:
An interrupt is generated when the external input turns ON, OFF, or both.
• Counter Mode:
External signals are counted, decrementing the PV from an SV, and an
interrupt is generated when the PV equals 0.
interrupt is generated when the PV equals 0.
The interrupt mode for each interrupt input is set using the MSKS(690)
instruction.
