The processing load in the primary
periodic task is too heavy. Reduce the amount of processing in
the primary periodic task or set the
control period to a value that is long
enough not to cause operation prob-
lems. Check the task period in the
Task Period Monitor of the Sysmac
Studio. Write the programs for the primary
periodic task so that they perform only
the processes required in the speci-
fied period. Or, set the period of the
primary periodic task to be long
enough to complete all required pro-
cessing.
