Upper Limit/Lower Limit Rule Type

The Upper Limit/Lower Limit rule type checks whether the measured values exceed the set linear limits. The event is triggered when a certain number of measured values exceeds the set limit.

Rule type variants

• Upper Limit/Lower Limit (Priority of Current Value) Rule Type
• Upper Limit/Lower Limit Rule Type (Calculated Limit)

Example

The rotational speed of a motor is monitored. An upper limit of 4000 rpm has been defined.

For example, if a measured value reaches 4200 rpm, the defined upper limit of 4000 rpm has been exceeded. An event is triggered.
