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.

Operator

Description

Rule Example

=

functions as 'equal to' with numeric characters or as 'like' with text strings

In a filtered subset of 1hp motors:
(Motor) Rated voltage = 120 v

>

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

<>

or 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; 460 V

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.

Is Null

ensures whether the user enters values for the item tag belonging to the rule component

Supply ACDC Is Null

Is Not Null

used for testing or comparing values or properties in a conjunction with another rule consistency

(Cable) Design length >= (Cable) Estimated length
(Cable) Design length Is not Null
(Cable) Estimated length Is not Null
Comment: if you do use the Is Not Null operator in this rule, the software treats the expression as true even if the values for the (Cable) Design length and (Cable) Estimated length properties are not defined at all.
