PAGE 2
Management level Building Level Network The VISONIK BPS on the management level communicates via the Building Level Network (BLN): 8884Z02E Insight Management station DCS PRV1 BPS Involved elements EKL-X BPS The following elements are involved in the Building Level Network: Element Description Management station The management station in its simplest build contains a Data and Communication Server (DCS) with Insight for graphical display and operation, and a printer for alarms and reports.
PAGE 3
Process level P-bus The VISONIK BPS communicates with the building services systems by means of the process bus, short P-bus: T 8884Z03E P-Bus BPS Elements and functions T I/O modules I/O modules The communication elements and functions on the process level are: Element Description/Function P-bus The P-bus is a proprietary data bus of Landis & Staefa. It has been designed as a control cabinet bus and, in its standard version (max. 50 m), consists of a 3-pin round cable.

Local operation and display Functions Local operation and display primarily is used for autonomous process stations. It comprises the following functions: • Indicating operating and error statuses • Changing setpoints, timeswitch entries, etc.
PAGE 6
Dial-up communication Functions Dial-up communication with the VISONIK BPS occurs via the BPS's interface COM1/TTY1 and a modem. It comprises the following functions: • • • • • Dial-up communication partners Establish and terminate connections Signal events Collect operating data Transmit process data Operation The VISONIK devices shown below can be used as dial-up communication partners for an autonomous BPS.
