FUNCTIONS
6.23 Interrupt from the Intelligent Function
Basic
Note6.79
CPU module executes an interrupt program (I ) by the interrupt request from the
intelligent function module.
For example, the serial communication module processes the data reception by an
interrupt program when the following data communication functions are executed.
Processing data reception with an interrupt program improves the data reception speed of
CPU module.

To execute an interrupt program by the interrupt of the intelligent function module, it is
necessary to designate the "Intelligent function module setting (Interrupt pointer
setting)" at the "PLC system" tab screen in the "(PLC) Parameter" dialog box.
You should also designate "System setting" at the intelligent function module.
Refer to the following manual when executing an interrupt program by the interrupt of
the intelligent function module.
Manual of the intelligent function module
Remark
Refer to Section 10.11 for the available interrupt pointer Nos. for an interrupt from
the intelligent function module.
When using an interrupt from the intelligent function module on the Basic model QCPU, check
the versions of the CPU module and GX Developer. (
