Any device that receives a GroupValueWrite telegram from the bus will look up the Group Address (= the Destination Address) via the Address Table.
If the Group Address is in the Address Table and the telegram is received error-free, then:
- The device will send a positive Link Layer acknowledgement
- The effected Group Object or Objects will be looked up via the Association Table
If the 'C' and the 'W' of the effected Group Object or Objects are set, then per such Group Object:
- The value of the object will be updated according to the data of the payload field of the telegram
- If e.g. such Group Object represents a relay of a switch actuator then this relay will be opened or closed
If the Group Address is in the Address Table, but the telegram contains at least one error, then:
- The device will send a negative Link Layer acknowledgement
If the Group Address is not in the Address Table, then:
- The device will not react
