Interrupt Pointer(I)

The interrupt pointer (I) is used as a label at the start of an interrupt program, and can be used in any programs.
(1) Number of available points
The number of points and the range available for the interrupt pointer are shown below.
Q00UJCPU, Q00UCPU, Q01UCPU
Q02UCPU, Q03UD(E)CPU, Q03UDVCPU, Q04UD(E)HCPU, Q04UDVCPU,
Q06UD(E)HCPU, Q06UDVCPU, Q10UD(E)HCPU, Q13UD(E)HCPU, Q13UDVCPU,
Q20UD(E)HCPU, Q26UD(E)HCPU, Q26UDVCPU, Q50UDEHCPU, Q100UDEHCPU
(2) Interrupt factors
The interrupt factors for the available interrupt pointers are shown below.
Interrupt factor
Interrupt by an interrupt module
Interrupt by a sequence-started module
Interrupt by the internal timer
Multiple CPU synchronous interrupt
Intelligent function module interrupt
*1 For available interrupt modules, refer to the following.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
*2 The corresponding module is an intelligent communication module. For details, refer to the manual for each module.
*3 Applicable when using the Universal model QCPU and motion controller that support the multiple CPU high speed
transmission.
*4 This module can be a serial communication module, MELSECNET/H module, Ethernet module, or high-speed counter
module. For details, refer to the manual for each module.
*5 Only the High-speed Universal model QCPU supports the use of I49.
To use the intelligent function module interrupt (
(interrupt pointer setting) is required in the "PLC system" tab of the PLC parameter dialog box. (
