Event Issuance For The Interrupt Program - Mitsubishi Electric L26CPU-BT User Manual

8.3.2

Event issuance for the interrupt program

This function issues events (signals to execute an interrupt program) according to factors such as the on/off status of
specified RX, RY and SB devices and the match/mismatch status of specified RWr and SW device data, in order to
allow the programmable controller CPU to execute the interrupt program. This enables the high speed receive
processing without being influenced by the sequence scan.
Because the conditions for issuing the events are set using GX Works2, the number of program steps is reduced, thus
shortening the sequence scan time.
Events can be issued to all stations.
A maximum of 16 event issuance conditions can be set.
(1) Event issuance conditions
Events are issued under the following conditions:
On/off status of specified RX, RY and SB devices
Match/mismatch status of specified RWr and SW device data
When the link scan is completed
(2) Event issuance condition setting method
(a) First, set the "Interrupt Setting" in the network parameter setting.
If interrupt conditions are established when the link scan is completed, the interrupt is issued. If "Scan
Completed" is set to "Device Code", the interrupt is issued without conditions when the link scan is completed.
