Basic units, no cards

The Building Process Station, short BPS (or NetBPS if equipped with an Ethernet

card), is a programmed DDC station for building automation and control featuring

the following properties:

• Three basic units, tailored to the respective I/O module load

• Plug-in program and communication cards

• Local operation and display via operating cards, terminal, or PC

Variant without P-bus connection for use as a master unit to integrate L&S room

control systems and RWI controllers or third-party systems.

Use

Both the BPS and the NetBPS are used in commercial buildings to execute

sophisticated HVAC and related tasks:

• As autonomous process stations, local or remote via telephony (BPS only).

• Together with other process stations on either Building Level Network (SDLC ring) or

Ethernet with superposed VISONIK Data and Communication Server.

As a master or Communication Front End (CFE) to integrate L&S room control systems

and standard process units (RWI) as well as third-party system.

The BPS can be used in VISONIK systems from DCS V12. The NetBPS requires a

DCS from V20.

Technical design Operating voltage AC 24 V The PRV2… basic unit uses AC 24 V safety extra-low voltage "SELV" or protection by extra-low voltage "PELV" as per HD 384. I/O module supply The basic units with P-bus connection supply DC 24 V to the connected I/O modules via the P-bus. The basic unit's load by one I/O module is indicated with load units at 12.5 mA each. The maximum load for the basic unit types with P-bus is available in section "Type summary".
PAGE 7
Data exchange with I/O modules Data exchange with the I/O modules occurs via the three-core P-bus (process bus). This bus is described in detail in data sheet 8022 "Process Bus". I/O modules on the same P-bus have their own address in the number range of 1 to max. 255. The addresses are set using address plugs in the I/O modules. Refer to "Basic Data of the I/O Module System", data sheet 8102.
