Kit for Stand-Alone Operation and Advanced Diagnostic Module
The KT-MB-DM kit for stand-alone operation enables the installation of the FieldConnex
®
advanced physical layer diagnostics for non-FieldConnex–Power–Hub-based installations. The
advanced diagnostic module HD2-DM-A is installed on a motherboard enabling the connec
-
tion to 4 FOUNDATION Fieldbus H1 or PROFIBUS PA segments. The motherboards are con
-
nected to each other and to the diagnostic gateway (DGW) using a dedicated diagnostic bus.
The figure below shows an installation example.
Figure 4.3
System topology with diagnostic gateway and kits for stand-alone operation
The DGW provides 2 diagnostic bus channels. Depending on the selected integration solution
used, you can connect either of the following:
•
FDS/OPC Integration:
62 stand-alone kits (for both channels) / 31 stand-alone kits (for
each channel)
•
FOUNDATION Fieldbus:
16 stand-alone kits (both channels) /8 stand-alone kits (for
each channel)
Note
The diagnostic gateway FF-H1 connection must never be connected to device couplers like the
Fuchs Segment Protectors or FieldBarriers.
The diagnostic gateway must be connected directly to the trunk.
For best performance, we recommend using a separate FF-H1 diagnostic segment for
diagnostic gateways. Scheduled FB data must be kept to a minimum for this segment.

For best performance, use the same number of Power Hub motherboards on each diagnostic
bus channel.
