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.
