Condition attribute expressions

Use conditions to inform the one-line engine of the logical requirements necessary for a component to be considered active. Conditions may only contain tags, logical operators, relational operators, and numeric values. The following operators represent valid syntax that can be used for condition expressions:

Relational Operators

Operators	Definition
>	Greater than
<	Less than
>=	Greater than equal
<=	Less than equal
==	Equals
!=	Not equal

Logical Operators

Operators	Definition
&&	Logical AND
||	Logical OR

If a condition uses a variable tag, it must be a fully qualified variable tag that is configured in the system.

Example:

Cluster1.TagName > 1

or

Cluster1.EquipmentName.Item > 1

In expressions containing more than one logical operation statement, each statement must be enclosed in parenthesis.

Example:

(Cluster1.EquipmentName.IteamA > 1) && (Cluster1.EquipmentName.ItemB == 0)
