BPS operating hours count

Function sheet

This function sheet provides an overview of the VISONIK BPS operating hours

count functions.

The VISONIK BPS acquires the operating hours of plant elements through continuous

polling of the operating states. The VISONIK BPS can:

•

Add up operating hours and transfer them to the DCS

•

Determine limit value violations of operating hours

The illustration below shows an application example:

BPS

P-Bus

8898Z01

SBR1

DCS

M02

M01

In this example, the VISONIK BPS acquires the following values:

Element Values

ML The duration of the frost status via the status module, point type ML

SBR1 The operating hours of the heating coil pump (M01) and the supply air fan

(M02) via feedback message of the switching modules, point type SBR1

The BPS transfers these values at intervals that can be defined to the Data and

Communication Server (DCS) for storage and further processing such as:

– Printing of spontaneous event reports

– Execution of maintenance reactions on reaching the operating hours limit values
