Input Interrupts Section 7-3

Clearing Recorded Interrupts

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.

The CLI(691) instruction clears the interrupt event information recorded while all interrupts were disabled by the DI(802) instruction.

7-3-1	Applicable Models
		Model number	Functions
		FQM1-MMP21	Motion Control Module for Pulse I/O
		FQM1-MMA21	Motion Control Module for Analog I/O
7-3-2	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.
	Note If the input interrupts are not being used, interrupt tasks 000 to 003 can be
		used as interrupt tasks for other interrupt functions.
7-3-3	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.

•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.

The interrupt mode for each interrupt input is set using the MSKS(690) instruction.

7-3-4 Input Interrupt Specifications

Input Interrupt Mode

Item	Specification
Interrupt condition	Contact inputs 0 to 3 (CIO 0000.00 to CIO 0000.03) turn ON,
	OFF, or both
	Note Set the interrupt condition in the System Setup.
Interrupt task num-	CIO 0000.00 to CIO 0000.03: Interrupt tasks 000 to 003
bers
Response time	0.1 ms for ON interrupt condition
	The response time is measured from when interrupt condition
	is met until interrupt task execution starts.
Signal pulse width	ON: 0.1 ms min., OFF: 0.2 ms min.
