General information
Prosonic Flow 93 can be equipped with a PROFIBUS-PA interface in accordance with
the fieldbus standard PROFIBUS-DP (EN 50170 Volume 2).
As a consequence, Prosonic Flow 93 can exchange data with process control systems
which satisfy this standard. The integration in a control system must be in accordance
with the PROFIBUS-PA Profile 3.0 Specifications.
The selection of the international IEC 61158-2 (MBP) (International Electrotechnical
Commission) transmission standard ensures a future-proof field installation with
PROFIBUS-PA.
Communications partner
In a control system, Prosonic Flow 93 always serves as a slave and can thus, depending
on the type of application, exchange data with one or more masters.
The master can be a process control system, a PLC or a PC with a PROFIBUS-DP
communications adapter card.
!
Note!
During project planning, please remember that Prosonic Flow 93 consumes 11 mA.

Caution!
To prevent severe device failures (e.g. short-circuits) from having effect on the
PROFIBUS-PA segment, the IEC 61158-2 (MBP) interface is equipped with a fuse. If the
fuse blows, the device is permanently disconnected from the bus. In this case, the I/O
module must be replaced (see Page 140).
