TURCK Diagnostic Power Conditioner System
 
The DPC-System (Diagnostic Power Conditioner System) is a power supply system for the installation of FOUNDATION fieldbus H1 segments.  It also provides comprehensive diagnostic functions for monitoring FOUNDATION fieldbus segments, and supports asset management for the entire physical layer.
 
A DPC system consists of one or more module racks (DPC-49-MB-RC), each with up to eight isolated power supply modules (DPC-49-IPS), and one advanced diagnostic unit (DPC-49-ADU).  Up to four H1 segments for each module rack can be operated and monitored redundantly.  The diagnostic data from the H1 segments is transmitted via the HSE field device (DPC-49HSEFD/24VDC) to the higher level asset management system.
 
The advanced diagnostic unit (DPC-49-ADU) is used as a communication and diagnostic interface between the H1 segments and the HSE field device, and monitors the electrical and communication parameters of the H1 segments.  Operation without the advanced diagnostic uint is possible.  In this configuration, a simple diagnostics unit provides local diagnostics.
 
The diagnostic information that is collected is then transmitted via the HSE field device to the higher fieldbus level (e.g. to the host) as diagnostic and alarm data.  The diagnostic units and isolated power supply modules can be plugged and unplugged during operation (hot swappable).
 
The DPC system provides complete galvanic isolation; H1 to H1, H1 to 24 VDC power, ADU/DU to H1, and HSE to H1.

Fieldbus – The Dynamic Asset
 
Information concerning the components of the control system and field devices is typically stored and monitored by that control system. Information concerning assets that make up the communication infrastructure (physical layer components) are simply stored in an asset management system – until now. With the DPC system, the physical layer components are continuously monitored providing virtually instantaneous information regarding the quality and the status of the communication link. This aspect of the system is the key to achieving the main objective of asset management: to minimize maintenance and lower system operating costs.
 
TURCK has made drastic improvements to existing physical layer components for use in FOUNDATION fieldbus applications.  By continuously monitoring every physical layer component, the DPC treats the entire physical layer as an asset and manages it accordingly. The DPC system also supports the set-up of fieldbus assets by using localization of error sources, as well as documentation indicating a “good condition” of the segment structure. The DPC system provides an option for redundant segment supplies. The system, fully loaded, can accomodate up to 16 fully redundant FOUNDATION fieldbus segments, each with an output of 800 mA and 30 VDC.  Diagnostic data is available via a DTM, standard FOUNDATION fieldbus function block libraries or an embedded web server in the HSE field device.
 
The DPC system can also be used to supply devices in hazardous classified areas when Fisco power supplies/repeaters or multibarriers from TURCK are used.

Backplane for the DPC System: DPC-49-MB-RC
 
The module rack DPC-49-MB-RC consists of a backplane and the actual rack system for the power supply modules and the diagnostic unit. The single components of the system are electrically linked via the connection terminals of the backplane from the user side.  From an electrical perspective, the backplane is considered passive (no electrical components). The power can be supplied via two 2-polescrew connectors.  The connection to the host system is established via two system cables.  Optional pre-assembled system cables are available at TURCK.

Power Supply Module: DPC-49-IPS
 
The power supply module provides up to 30 VDC and 800 mA for the installation of the segment.  Due to this broad segment allocation (up to 1900 m) is possible without restriction. If two power supply modules are applied, a redundant operation of the segment is possible.  Therefore the power supply modules can be plugged and unplugged during operation (hot swapable). The device features a LED display for segment status.

HSE Field Device: DPC-49-HSEFD/24VDC
 
The diagnostic data from the H1 segments is transmitted via the HSE field device module DPC-49-HSEFD/24VDC to the higher level Asset Management System. Only the diagnostic data from the DPC-49-ADU is transmitted, not the process data of the H1 field device. Each diagnostic unit monitors up to four H1 segments.
 
The HSE interface module is a FOUNDATION fieldbus field device that contains one resource and one transducer block and various standard function blocks.  On the basis of these standard  function blocks, suitable applications for the analysis of the diagnostics data can be programmed in the control system.
