Advanced Diagnostics
Hardware Installation
Note
The diagnostic gateway FF-H1 connection must never be connected to device couplers like the
Pepperl+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.
4.2 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
For best performance, use the same number of Power Hub motherboards on each diagnostic
bus channel.
