Event Issuance For The Interrupt Program - Mitsubishi Electric MELSEC-Q Series User Manual

8.3.2

Event issuance for the interrupt program

A request for the interrupt to a CPU module is issued when the conditions that have been set using a programming tool
are satisfied, and the interrupt program can be executed. This function is used to stop the control and execute an
interrupt program upon an error or for other purposes.
Because the conditions are set using a programming tool, the number of steps in a program is reduced, shortening the
scan time.
An event can be issued to all stations.
(1) Conditions for event issuance
Up to 16 conditions for event issuance can be set.
The following conditions can be set for interruption.
• When RX, RY, or SB is turned on or off
• Match/mismatch of data in RWr and SW
• When a link scan is completed
(2) How to configure the interrupt settings
Configure the settings in "Interrupt Settings" of the network parameter and in "Intelligent Function Module
Interrupt Pointer Setting" of the PLC parameter. (
