1.3 Thresholds
The threshold is a value that is the criterion for reporting to a configured device (report device) when the value
counted for the operation time or operation count (operation time device value or operation count device value) has
reached the threshold value. 1 is written to the configured device when the operation time and operation count reach
the threshold.
Example: When the value of operation time device LKR 0 reaches the threshold set for level 1 through level 3, 1 is
written to the report device configured for each level, LM 1 through LM 3.
