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 (the value of Operation Time Device or Operation Count Device)
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 LKR0 reaches the threshold set for level 1 through level 3, 1 is
written to the Report Device configured for each level, LM1 through LM3.
