Siemens Building Technologies VISONIK Building Process Station BPS / NetBPS CM2N8305en
Landis & Staefa Division 05.10.2000
Functions
The BPS/NetBPS together with the PVA3… program card contains all common DDC
standard functions for the planned application range:
Functions Description
Basic functions When processing the plant operating program, the BPS/NetBPS
executes the basic functions together with the connected I/O
modules:
Signalling, measuring, counting, switching, positioning.
Processing
functions
The BPS/NetBPS processing functions comprise all required
building automation functions such as:
− Supervising
− Controlling
− Processing/optimising/statistics
System functions The BPS/NetBPS system functions contain the general automation
station services such as:
− Operation and display, local or via telephony (BPS only)
− Communication via the various interfaces
− Running of plant operating programs
Refer to the data sheets on the VISONIK BPS; see overview N8880E.
The plant operating programs are created with the aid of the VISOTOOL AUTOGEN or
European Tool Set software tools by combining predefined and tested function blocks
stored in the program library. Free programming by using COLBAS *) is also possible.
This also allows for customising solutions to meet special requirements.
*) COLBAS = Control Oriented Language for Building Automation Systems
The BPS/NetBPS master functions depend on the integrated system:
System Functions
L&S room
control
systems
Master functions for MONOGYR, TEC, AEROGYR/RWI, BATIGYR,
and DESIGO RX such as:
− Preset operating states for rooms and room groups.
− Read actual values and write setpoints of individual units.
− Summer-winter changeover, etc..
The documentation on basics for the various systems provide
information on the specific scope of the master functions.
Third-party
systems
The CFE functionality must be specified and implemented for each
project.
The dialog containing the unit's functions from operating cards and associated displays
and operating buttons is described in section "Mechanical design".
The BPS/NetBPS supports service and diagnostic functions as follows:
− Tool connection for commissioning, configuration changes, and service.
− Service and diagnostic cards for service.
The unit's response with regard to function reliability and system safety is described in
section "Technical design".
