Block diagram
The diagram illustrates the function of the blocks available in the device. A communication tool
or a PLC with "master class 2" functionality can access all blocks for parameterization
acyclically.

Important
Detailed descriptions of the blocks / parameters appear in the separate "PROFIBUS PA
interface description" for the device (part no. D184B093Uxx). This appears on the CD included
in the scope of supply.
Parameter settings are made acyclically via the device's PROFIBUS PA-DTM.

Description
Contains device-specific properties such as software
version, TAG no., etc.
Contains flowmeter data such as nominal size, k factor
measuring ranges, etc., along with all manufacturer-specific
parameters not contained in the function blocks.
Users can select the measured values which are relevant for
their applications (Qv (volume flow, Qn (volume flow under
standard conditions), Qm (mass flow) or temperature
(option)) via the channel selector.
The totalizer reading can be checked or modified via the
PROFIBUS PA-DTM in SMART VISION here acyclically, for
example. The totalizer can be reset cyclically.
