Product Specifications
2 Product Specifications
2.1 Overview and Application
The Pepperl+Fuchs FieldConnex®Power Hub for PROFINET IO is based on a modular
system. The system consists of various motherboards with slots, plug-in modules, e.g., power
supplies, diagnostic modules, and a gateway. The gateway couples up to 4 PROFIBUS PA
segments to PROFINET IO system interfaces. On the PROFIBUS PA trunk a high energy level
is fed to the field devices via device couplers, such as FieldBarriers or Segment Protectors. A
dedicated version of the Power Hub (DART) supports the intrinsically safe concept for fieldbus.
In its basic version, the diagnostic module is used ensure to the functional integrity of the Power
Hub. The advanced version additionally monitors the physical layer of the 4 PROFIBUS PA
segments online, this way enabling the detection of degradation and faults in real-time during
operation. Measurement data and alarms are transmitted to the control room. This makes the
fieldbus physical layer visible and accessible as an active component in plant asset
management systems. Operating personnel are enabled to decide on proactive measures to
avoid unwanted situations while the plant is running smoothly. For further information on the
diagnostic capabilities, refer to the specific product documentation.
The Power Hub offers various redundancy options such as gateway and power supply
redundancy.
A complete tool chain supports the engineering for system integration. A gateway device type
manager (DTM) and a web server enable the access to status and diagnostic of infrastructure
components and connected field devices. The gateway DTM allows using the DTMs of the
connected PROFIBUS PA devices for parameterization, access to diagnostic, and status
information.
