The Desigo system can be subdivided into two levels:
• Management level
• Automation level
The automation level forms the interface to the eld level and includes room automation as well. By virtue of distributed intelligence,
each of these levels operates both autonomously and in a network.
The principal Desigo system components
• The Desigo management station for superimposed operation
and monitoring, graphics-based display of the process, auto-
matic alarm distribution and a wide range of different data
analysis options using standardized protocols
• Desigo Total Room Automation (TRA) is an open and
programmable room automation product range covering
lighting, shading, and HVAC and allowing for individually
tailored room solutions at a high level of energy efciency
• Desigo PX automation range for control, operation and moni-
toring of primary plants. Desigo Touch and Web can operate
the plant via touch panel or Web client
• Compact and proven Desigo room automation system RX for
autonomous comfort control in individual rooms
• Desigo TX-I/O modules, which provide the interface to the
devices at the eld level, the sensors and actuators
• Desigo Open for the integration of a wide variety of plants and
protocols at all system levels
Desigo system topology
One of the key benets of Desigo is its scope for gradual extensions, from the smallest systems to large, geographically distributed
systems.
