Create the program for interrupt task 2 (scheduled interrupt 0), which is exe-
cuted by the input interrupt. Always put an END(001) instruction at the last
address of the program.
Selecting the Scheduled Interrupt Task
This example shows how to execute interrupt task 2 at 30.5 ms intervals.
1. Use the CX-Programmer to set the scheduled interrupt time units to 0.1
ms.
2. Use the CX-Programmer to create the interrupt program allocated to inter-
rupt task 2.

When execution condition W0.00 goes ON, MSKS(690) is executed to enable
the scheduled interrupt with the reset start specified. The timer is reset and
timing starts.
