System Components
2.2.1
Motherboard
MBHC-FB-4.GT*
The motherboard MBHC-FB-4.GT enables the supply of PROFIBUS PA 4 segments and the
connection to a fieldbus host system. 4 sockets hold the power supply modules, each
supplying 1 of the 4 segments. 1 dedicated socket holds the diagnostic module and another
dedicated socket holds the gateway from PROFIBUS PA to a host system.

Gateway Modules HD2-GTR-4PA*
Gateway HD2-GTR-4PA (Segment Coupler SK3)
The gateway is a FieldConnex
to PROFIBUS PA segments. The Segment Coupler makes each PA device appear as if it was
related to DP with regard to addressing, cyclic/acyclic data exchange, and transfer rate. The
gateway operates with power supply modules connected to the same or a separate
motherboard. The gateway provides a PA master for each segment and thus enables short bus
cycle times.

product information.
Gateway HD2-GTR-4PA.PN
The gateway is a FieldConnex
and integrates communication of 4 PA segments into PROFINET IO systems. The gateway
operates with power supply modules connected to the same or a separate motherboard. The
gateway provides a PA master for each segment and thus enables short bus cycle times.
