Electrical installation system for use in KNX bus system of building automation system for operating e.g. monitoring device, has transmitter, and comparison unit for comparing commands with commands contained in request

摘要

The system has a transmitter (1) comprising a command transmission unit (3) for transmitting commands of a bus system i.e. KNXbus system, to a receiver, and a command receiving unit for receiving the commands from the transmitter. A request receiving unit receives a request from the transmitter, and a status transmission unit transmits status of the receiver to a status receiving unit (5) of the transmitter. A comparison unit compares the commands with commands contained in the request, where the transmitter and/or receiver comprise a microcontroller.
