ABB FSM4000 - Connection Examples for Peripherals (incl. HART)

FSM4000 ELECTROMAGNETIC FLOWMETER | OI/FSM4000-EN REV. E 43
Bus address
The bus address is automatically assigned or can be set in the
system manually.
Addresses are detected using a unique combination of
manufacturer ID, device ID, and device serial number.
System integration
The following are required:
• DD (Device Description) file, which includes the device
description.
• CFF (Common File Format) file is required for engineering
the segment. Engineering can be performed online or
offline.
For additional information, see the separate interface
description.
The files required for operation can be downloaded from
http://www.fieldbus.org.
