Advanced Diagnostics
Hardware Installation
For the FDS/OPC integration, up to 125 DGW or 1 000 ADMs (whichever maximum is reached
first) are supported for a single FDS server installation. For the FOUNDATION Fieldbus integra-
tion, this limit does not apply because every DGW is a single FF-H1 field device without any
connection to the other gateways.

4.2.1 Installing the Diagnostic Bus
The maximum length of the diagnoastic bus channel is 30 m.
Installing the Diagnostic Bus
1.
In order to connect the diagnostic gateway to the FieldConnex
2.
In order to connect the Power Hubs with each other, use a 4-wire cable or the optional ACC-
MB-HDC link cable.
3.
Use shielded wires for the diagnostic bus in EMC-sensitive areas. Connect the cable shield to
the grounding terminal of the gateway motherboard.
4.
The principal way of connecting stand-alone kits to each other and to the diagnostic gateway is
shown in the figure below.
5.
The terminals used at the diagnostic gateway depends on the kit used.
KT-MB-GT2AD.FF:see chapter 3.3.1
