Attribute Logical Operators

Attribute logical operators are required when more than one symbol is associated with a room. Each symbol associated with a room may have instances of the same attribute. The logical operator of an attribute specifies how the value of each symbol instance will be combined to create the total room value of the attribute. The table below shows the available operators for analog, digital, and serial attributes.

Attribute Type	Logical Operator	Description
Analog	Sum	Room value is calculated as the sum of the attribute across all symbols associated with the room.
	Average	Room value is calculated as the average of the attribute across all symbols associated with the room.
	Minimum	Room value is calculated as the attribute with the lowest value across all symbols associated with the room.
	Maximum	Room value is calculated as the attribute with the highest value across all symbols associated with the room.
	Last	Room value is calculated as the attribute that changed most recently across all symbols associated with the room.
Digital	And	Room value of the attribute is calculated using a binary AND operator across all symbols associated with the room. Logic is as follows: 1 AND 1 = 1 0 AND 1 = 0 0 AND 0 = 0
	Or	Room value of the attribute is calculated using a binary OR operator across all symbols associated with the room. Logic is as follows: 1 OR 1 = 1 0 OR 1 = 1 0 OR 0 = 0
	Exclusive Or	Room value of the attribute is calculated using a binary Exclusive OR operator across all symbols associated with the room. Logic is as follows: 1 XOR 1 = 0 0 XOR 1 = 1 0 XOR 0 = 0
	Last	Room value is calculated as the attribute that changed most recently across all symbols associated with the room.
Serial	Concatenate	Room value of is calculated as the concatenation of the attribute across all symbols associated with the room.
	Last	Room value is calculated as the attribute that changed most recently across all symbols associated with the room.
