OMMUNICATIONS
The first stage of creating a Fieldbus Gateway Manager database is to configure the
communications ports of the Fieldbus Gateway to indicate which protocols you want to use,
and which remote devices you want to access. These operations are performed from the
Communications window, which is opened by selecting the first icon of the Fieldbus
Gateway Manager main screen.
As can be seen, the Communications window lists the unit’s available ports in the form of a
tree structure. Fieldbus Gateways have three primary serial ports, with the option to add a

that is capable of running four communications protocols simultaneously.

but it will obviously not be available for download if it is so employed. This is
not an issue if the USB port is used for such purposes, and it is highly
recommended that you use this method of download if you want to connect
serial devices via the programming port.

Communications window, and press the Edit button next to the Driver field in the right-hand
pane. The following dialog box will appear…
