Describes operators available on the Consistency tab of the Rule Properties dialog. Also, provides examples of rules that you can create using a particular operator.
In the examples shown in the table, the rule components are displayed in brackets to separate them visually from properties or values. When a string that follows an operator does not start with a bracket, this indicates a single component rule.

Description |
Rule Example |
|
= |
functions as 'equal to' with numeric characters or as 'like' with text strings. When using a Copy operand this operator initiates the copy rule. |
In a filtered subset of 1hp motors: |
|
> |
greater than |
(Cable) Insulation rated voltage > (Motor) Rated voltage |
|
>= |
greater than or equal to |
(Motor) Rated power >= (Motor) Brake power |
|
< |
smaller than |
(Motor) Asynchronous speed < (Motor) Synchronous speed |
|
<= |
smaller than or equal to |
(Motor) Asynchronous speed <= (Motor) Synchronous speed |
|
<> |
not equal to |
In a filtered subset of heaters with heater rated power above 10kW: (Heater) Number of phases <> 1 |
|
IN |
any of the specified values |
In a filtered subset of 10hp motors: (Motor) Rated Voltage IN 380 V; 415 V; 400 V; 0.4 kV; Comment: The values are case- sensitive and must be typed exactly as they appear in the Data Dictionary. The value separator must be either a semi-colon or a comma. Important: In this example, even though the values 400V and 0.4kV produce the same result numerically, you must enter both values. This is because in SmartPlant Electrical, the software does not convert between one value and another. |
