A-3.9 Timed Interrupt Performance
The sweep impact of a timed interrupt invoking an empty program block or timed program measures the
overall time of fielding the interrupt, starting up the program or block, exiting the program or block, and
restarting the interrupted task. The minimum, average, and maximum interrupt period reflect the time
from when the first line of ladder logic is executed in the timed interrupt block.
