BPS dial-up

communication

Function sheet

When equipped with a communication card COM1 and a modem on interface

TTY1, the VISONIK BPS can communicate via the public telephone network with

various partners of VISONIK systems.

This document describes the tasks and functions of dial-up communication.

The VISONIK BPS uses dial-up communication to transfer data between partners in

different locations:

BPS

V.24

DCS

V.24

TTY1

8889Z01E

The respective partners are connected to the public telephone network by means of

their V.24 interfaces and the modems only for the duration of the transfer.

Dial-up communication can be used to execute the following functions and thereby

transfer the corresponding data between partners:

Function Data examples

Signal events Data from building services plants such as:

−

Alarm messages on limit value violations

−

Plant state messages

Collect operating data Data from building services plants such as:

−

Temperature values

−

Example Topology The illustration below provides an example for dial-up communication: – Various plants in different locations with autonomous process stations are administered by a central management station (DCS with Insight and printer). – Each separate VISONIK BPS (1...3) has a DCS defined as partner 1. – Partner 2 represents a teleterminal, e.g., the PC of the service crew.
