The DPC system (Diagnostic Power Conditioner) is a power supply system for the installation of FOUNDATION™ fieldbus H1 segments. It provides extensive diagnostic options for monitoring FOUNDATION™ fieldbus

segments and thus supports plantwide asset

management.

A DPC system consists of one or more

DPC-49-MB-RC module racks, each with up

to eight DPC-49-IPS power supply modules

and one DPC-49-ADU or DPC-49-DU diagnostics module . Up to four H1 segments for

each module rack can be operated and monitored redundantly in the FOUNDATION™

fieldbus network. The diagnostic data of the

H1 segments can be transmitted via the HSE

interface module DPC-49-HSEFD/24VDC to

the higher level Asset Management system.

The DPC-49-HSEFD/24VDC HSE field device

transmits the diagnostic data of up to 16 H1

segments via the FOUNDATION™ fieldbus

HSE interface module to the higher-level asset management system. Only diagnostic data of the DPC-49-ADU diagnostics modules

is transmitted via the HSE interface module,

and not the process data of the H1 segments.

Each diagnostics module monitors up to four

H1 segments.

As a FOUNDATION™ fieldbus device the

HSE interface module features a resource

and transducer block as well as several standard function blocks. On the basis of these

standard function blocks, suitable applications

can be programmed in the control system for

the analysis of diagnostic data.
