Event Issuance For The Interrupt Program - Mitsubishi LJ61BT11 User Manual

8.3.2 Event issuance for the interrupt program

8 - 60
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.
1) Input format
Set the data input format for "Word Device Setting Value".
Setting range: DEC.

Setting range: RX
3) Device No.
