Cyclic data exchange can be connected redundantly to the DP line by
using the redundant Gateway Motherboard MB-FB-GTR and two
HD2-GTR-4PA Gateways.
The Gateway
"Flying Redundancy" (chapter "Redundancy Concepts" on page 63) as
well as all non-redundant DP Masters.
In summary, the Gateway is responsible for the following tasks:
• Conversion of the PROFIBUS DP physical layout to that of the
PROFIBUS PA
• Adjusting the DP transmission rate to the PA transmission rate
• Galvanic isolation between PROFIBUS DP and PA
• Elementary functional diagnostics via LEDs
• Ensuring increased availability through redundant coupling of
cyclic data exchange (with redundant layout)
• Acyclic Parameterization of Gateway parameters by
FDT/DTM
• Redundancy diagnostics (with redundant layout)

Segment Supply

Power is supplied to the field devices through Power Hub Modules on a
Power Hub Motherboard (simplex: 4 Power Hub connection slots, red-
undant: 8 connection slots) and via bus lines to the individual segments.
PA segments can receive redundant power supply if the redundant Po-
wer Hub Motherboard is used along with two Power Hub Modules for
each segment.
In summary, the supply is responsible for the following tasks:
• Power supply of field devices: power and communication signal
• Redundant supply for high system availability
• Elementary diagnostic information via LEDs
• Advanced Physical Layer Diagnostics via the HD2-DM* Diagno-
stic Module and the FDT/DTM software package (see corre-
sponding documentation).

Motherboards

Gateway motherboard simplex MB-FB-GT
The gateway motherboard simplex MB-FB-GT allows the connection of
the Fieldbus Power Hub motherboards MB-FB*.GEN or MBHD-
FB*.GEN using a standard cable. A socket will hold the DP/PA Gateway
HD2-GTR-4PA. The Built-In Slave of the HD2-GTR-4PA can be addres-
sed using the DIP switch on the motherboard.
Subject to reasonable modifications due to technical advances.
