This rule is used to create a relationship between a tag and a constant value. For example, if a datasheet refers to a tag that must be classified as a Pump, and the information does not exist in the datasheet, you can use this rule to classify the tag as a Pump.
The tag constant rule can be defined in the following way:
RT =TC|TNS = <Display Name of the TNS item>
For example:
RT =TC|TNS = TagType
To configure the TagConstant rule, use the following steps:
-
In the Editing Rule for <Rule Name> window, select the property to store the extracted value from the Related Attribute list. For example, Tag Type is the related attribute.
-
Type the name of the attribute in the Value box. The extracted property is related to this attribute. For example, type Pump in the Value box to classify the tag as a Pump.
-
Click OK.
