5.2 Application Task Start by Interrupt I/O Input

5.2.1 Outline

The IR.LINK module can cause an interrupt with an DI input signal and start an application task
(interrupt start application task) that was previously registered. The IR.LINK module can cause
8 interrupts. To start the interrupt start application task (hereafter abbreviated as the interrupt
task), set the IR.Station and register the interrupt tasks.
In the S10V, the interrupt task is available only when the CMU module is installed. The
interrupt task is not available with the LPU module only.

5.2.2 Setting and installing the IR.Station

Setting station number
Set the station number of the IR.Station to "01". If any value other than "01" is set, the task
is not started and fetched as input data only.
Installing the DI module
Install the DI module of the interrupt I/O input by the just right side of the IR.Station module.
If it is installed in any other location, the task is not started but fetched as input data only.
The task is started when the input signal changes from OFF into ON (from the low level into
the high level).

When station number is not "01",
the DI data does not become

an interrupt input.
Install it by the just right
side of the IR.Station module.
The first 8 points become interrupt inputs.
