1) How to Prepare Interrupt Program
Generate the task in the project window of XG5000 as below and add the program to be performed by
each task. For further information, please refer to XG5000 user’s manual.
2) Task Type

3) Processing Method of Task Program
Here describes common processing method and notices for Task Program.
(1) Features of Task Program
y
Task Program is executed only when execution condition occurs without every scan repeat
processing. When preparing Task Program, please consider this point.
y
For example, if a timer and counter were used in cyclic task program of 10 second cycle, this timer
occurs the tolerance of max. 10 seconds and the counter and the timer and as the counter checks
the input status of counter per 10 seconds, the input changed within 10 seconds is not counted up.
