Desigo PX: the scalable automation systemThe Desigo PX automation system meets all the requirements associated with the control and monitoring of heating, ventilation, air conditioning systems and other building services. The most striking features of Desigo PX are the scalability of the system with its programmable automation stations and graded range of operator units, and the system's openness.Web client PXM20...

Modular design for universal applicationWith its modular design, Desigo PX can be adapted to specific requirements and needs, making cost-effective DDC technology a possibility even in small HVAC systems. Investment costs are limited to those system components that are actually needed. This innovative approach allows phased expansion of Desigo PX into a building automation and control system as and when required.

BACnet communications for maximum opennessDesigo PX sets new standards in relation to present and future communications technologies. The use of BACnet /LonTalk or BACnet/IP underlines the openness of our systems and our utilization of the latest communications technologies. BACnet opens up the system, to allow easy integration of systems and components from third-party manufacturers.

Made-to-measure operator unitsThe various operator units in the Desigo PX range more than satisfy all the various requirements in terms of location and function. Web client (PX-WEB) The plant can be monitored and operated from a Web client via a Web controller. In the event of a fault, the Web controller transmits SMS messages and allows remote diagnostics via Web client. The PXM10 and PXM20 operator units, which can be optimized for different categories of user (e.g. resident engineer), offer users an easy means of checking the operation of the building services plant or of modifying the comprehensive time schedules to take account of changes in occupancy. Room units optimized for building occupants can be used for simple and direct local operation of the plant. In this way, the room temperature in a conference room, for example, can be easily adapted to individual needs.

QAX room units

A family of programmable automation stationsPXC automation stations With the PXC family of programmable automation stations, Desigo PX offers maximum flexibility in the control and monitoring of building services systems. Comprehensive system functions such as alarm management, time scheduling and trend data storage cover all the requirements associated with the operation of a building. The distributed automation stations, available in two categories, operate autonomously. Communication is via the open BACnet protocol. Professional software tools are available for engineering and other processing of the automation stations. The starting point for the engineering of the program functions is the range of userfriendly application blocks and function blocks in the new programming language D-MAP (Desigo Modular Application Programming). D-MAP is optimized for building services applications and is based on the IEC 1131 standard. The graphical user interface of the software tools ensures an efficient approach.

Scope for phased expansionThe Desigo PX automation system can be expanded step by step into a full building automation and control system. Desigo Insight The Desigo Insight management station offers convenient multi-user operation system wide. It can be connected to Desigo PX via Ethernet/IP, LonTalk / LONWORKS or by modem. Desigo RXC room controllers can b
