In order to provide advanced diagnostics for FieldConnex
mounted on the Power Hubs and are connected to each other and to the diagnostic gateway
(DGW) via a dedicated diagnostic bus. The figure below shows an installation example.

Figure 4.1 System topology with diagnostic gateway, Power Hubs and advanced diagnostic modules
The DGW provides 2 diagnostic bus channels. Depending on the PCS connection used you
can connect either of the following:
• FDS/OPC: 31 Power Hub motherboards (for each channel) / 62 Power Hub motherboards
(for both channels)
• FOUNDATION Fieldbus: 8 Power Hub motherboards (for each channel) / 16 Power Hub
motherboards (for both channels)
Note
For best performance, use the same number of Power Hub motherboards on each diagnostic
bus channel.
For the FDS/OPC integration, up to 125 DGWs or 1 000 ADMs (whichever maximum is
reached first) are supported for a single FDS server installation. For the FOUNDATION Field-
bus integration, this limit does not apply because every DGW is a single FF-H1 field device
without any connection to the other gateways.
