Desigo™ Overall topology
One of the key benefi ts of Desigo™ is its seamless expansion capability, starting from the smallest system up to comprehensive and distributed large
systems.
Freely programmable automation stations
Desigo PX offers maximum fl exibility with freely programmable automation stations
for primary plants. This way, building services plants can be optimally controlled and
monitored. Comprehensive system functions such as alarms, time scheduling and trend
data storage cover all the requirements associated with the operation of a building.
The distributed automation stations, available as modular and compact series, operate
autonomously.
Desigo PX excels in consistent openness of the system and the scalability of its freely
programmable automation stations and operator units, making cost-effective DDC
technology a possibility even in smaller HVAC systems. Whether for new buildings or
modernization projects, investment costs are limited to the system components that are
actually needed.
Maximum openness
The consistent and coordinated use of standards like BACnet, KNX, LonWorks or AMEV
emphasize the openness of Desigo for maximum overall effi ciency. The native BACnet
automation stations offer a multifunctional integration platform used to connect third-
party automation stations and open fi eld-bus networks to the BACnet network. A few
decentralized, distributed third-party devices can be connected quickly and
cost-effectively via Desigo TX Open and processed in the automation system.
A range of graded operator units
Building users and facility managers benefi t from a comprehensive range of touch
panels and operator units which can be used for targeted modifi cation of comfort
conditions or of the whole plant.
Especially ergonomic fi nger operation of the PXM40 (10 inch) and PXM50 (15 inch)
Desigo Touch and Web permits complete operation of Desigo PX automation stations
via the BACnet/IP Web interface PXG3.W100.
