The VISONIK Building Process Station, in short VISONIK BPS, is a programmable

DDC station used for building automation. Thus, the BPS contains all required

Processing functions

•

System functions

This document provides an overview of these functions.

The illustration below shows three typical VISONIK BPS applications:

a) As an autonomous station with I/O modules and local operation by means of

operating cards (POP Cards), equipped with printer and modem for dial-up

communications

b) In a linked system with several substations on a Building Level Network (BLN) with

superposed Data and Communication Server (DCS)/management station

c) As a master unit to integrate subsystems such as individual room controllers (TEC)

and AEROGYR ventilation controllers (RWI) via the Floor Level Network (FLN).

Processing functions General tasks Processing functions are used mainly for building installation processes. The tasks are: Supervise Control Regulate Calculaate/Optimize Statistics T T BPS 8883Z03E BPS functions The table below contains the processing functions that are available in the VISONIK BPS for the above tasks: Task Processing functions Supervising − Execution check on switching commands (feedback) − Limit value supervision (measuring and counting values) − Operating hours count (e.g.

System functions General tasks The system functions govern the general functions of the automation station. These include the following tasks: 8883Z04E Operation and display Communication Processing In the VISONIK BPS, the system functions primarily are ensured by their respective operating system. This operating system works in real time and allows for multi-tasking (simultaneous processing of different tasks). It is permanently saved in EPROM on the VISONIK BPS's program card.
