Building Management Software


Cost-effective and Scalable Integration and Facility Management with OPENweb, our web-based BACnet BMS.

OPENweb building management system software is a web-based BACnet building management system (BMS). It is installed on your PC or server depending on the size of your system. Using your standard browser or the DEOS proprietary visualization program OPENweb ControlPanel, you can safely access your local data via the Internet or intranet. Using the OPENweb ControlPanel allows you to work quickly and independently of your browser provider’s updates.

OPENweb is characterized by outstanding user-friendliness. Whether it involves access, the volume of information or the graphic display, the state-of-the-art web server technology allows the user interface to automatically adjust to user requirements and skills via the controller structure.

As a real BACnet building management system, OPENweb ensures openness in communication. The software integrates plants and systems from different manufacturers and ensures communication between various bus systems and products using standardized interfaces. DEOS AG offers a comprehensive basic package that you can expand with additional modules – precisely tailored to your individual requirements.

OPENweb ControlPanel

The OPENweb ControlPanel is the DEOS proprietary Browser for OPENweb. It can be used instead of your standard browser (Internet Explorer, Firefox). The advantage of using the OPENweb ControlPanel is its ability to enable you to work quickly and independently of the updates of your browser provider. It also helps you save time.

OPENweb Modular Expansions

Event Server

The event server organizes and manages the messages. Individual user profiles ensure that the message is always sent to the right place.

  • Alarm and message system
  • Alarm via SMS, e-mail, fax, etc.
  • ESPA-X protocol (Enhanced Signaling Protocol for Alarm Processes)

ESPA-X Protocol

This is a TCP/IP and XML-based communication protocol for controlling wireless paging installations. Through the ESPA-X service in the event server and an external ESPA-X server, the following additional functions can be activated:

  • Text-to-speech, reading-out of text messages on mobile and landline phones
  • The event server receives a real transmission confirmation. One of the pushbuttons on the terminal must therefore be pressed as confirmation.

Event Control Center

The Event Control Center (ECC) is the central software for displaying and handling alarms and messages. It provides the ability to configure user-specific views for the display and therefore shows all relevant information directly to the user. In addition to the chronological recording the acknowledgements, it offers many more options for filtering and processing alarms and messages.

  • Managing, displaying and processing alarms and messages
  • Interface can be configured for specific users

Fidelio Hotel Booking System

This module makes the room allocation such as Check-In, Check-Out and Pre-Check-In available as BACnet object. Each BACnet device in the network can access this information. Automatic selection and alignment of the room allocation takes place on system start.

  • Software module for linking to the Fidelio hotel booking system via BACnet protocol
