In order to use scope you have to define an expression as explained here.

Available scope attributes

The system has a number of predefined attributes which can be used in a scope expression


Scope expression limitations

1) The only operator supported in the expression tree object is "AND"

2) The system only support single level expression trees ie. you cannot have an expression tree object and an operand for another expression tree object.

Handling tags

Tags are a specific case. Tags always use the "tagtxt" attribute name.

In order to scope on tags you have to leave the Operator field blank ("") like so:

Tag element Json
	"Attribute": "tagtext",
	"Operator": "",
	"Value": "key = value",
	"DataType": "int"
