DEVICE EXPLANATION
(3) Interrupt factors
Table10.21 indicates the interrupt factors of the interrupt pointers.
: Available : Some interrupt pointers unavailable : N/A
* 1 : Refer to the following manual for the available interrupt modules.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
* 2 : The interrupt pointer I49 (high-speed interrupt function dedicated pointer) is available for the QnHCPU only.
* 3 : The Q02CPU cannot use the interrupt pointer I49 (high-speed interrupt function dedicated pointer).
* 4 : The interrupt pointers I40, I41 are available for the Redundant CPU only.
* 5 : For the error to which the error-time operation mode can be set in the PLC RAS setting of the PLC parameter
dialog box, an interrupt is executed only when the setting is "Continue".
* 6 : Applicable for the Universal model QCPU and Motion controller that are compatible with the multiple CPU high
speed main base unit (Q3
DB) and multiple CPU high speed transmission.
Not applicable for the single CPU system using the Universal model QCPU.
* 7 : The Basic model QCPU is I50 to 127.
* 8 : The target module is serial communication module, MELSECNET/H module, Ethernet module, and high-speed
counter module.
For details, refer to the manual for each module.
* 9 : The target module is the intelligent communication module etc.
For details, refer to the manual for each module.
* 10 : When using the interrupt module with the High Performance model QCPU, check the versions of the CPU
module and GX Developer. (
POINT
To use the intelligent function module interrupt (
Section 6.23), the intelligent
function module setting (interrupt points setting) is required at the "PLC system"
tab screen in the "(PLC) Parameter" dialog box.
