DESIGO building automation system

By use of standard BACnet functions, the BACnet scheduler programs can be
operated system-wide from the user-friendly operator units PXM20 and PX-WEB
and from the DESIGO INSIGHT management station.
Scheduler program on the DESIGO INSIGHT management station and on the PXM20 operator unit
For safety reasons, schedules and calendars are stored in the automation station,
so that in the event of a network or PC failure, the automation level can continue to
operate autonomously.
Access rights
Access rights can be used to filter information from the plant and system based on
the individual requirements of a user. The resident engineer or the service
engineers, for example, only have access to this important information. A distinction
can also be made between read access and write access. Certain users may be
able to read a value but not modify it, while other users may have extended access
rights, enabling them both to read and to modify values (edit).
Freely-definable access
rights
Only authorized personnel are granted access to the system via the operator units.
When a user enters a user name and password, the system verifies the associated
access rights and enables access to the relevant plant. Read and write access
rights can be defined in detail, right down to individual information points.
The following access classes are supported in the DESIGO system:
• Internal
• Extended service
• Basic service
• Administration
• Extended operation
• Standard operation
• Basic operation
Information flow under
control
Moreover, the Scopes function allows you to freely adapt the amount of information
on the management station to meet the needs and competencies of individual
users with regard to building area. Customizing the environment to each user
ensures clear areas of responsibility, so simplifying cooperation between the
various user groups.
