Promag 55 FOUNDATION Fieldbus blocks
The sensor signal is first prepared specifically for the flow in the measuring block (the
Transducer
Block
). The process variables are then passed to the
Analog Input function blocks
for control-
related processing (e.g. scaling, limit value processing).
The process variables go through the complete function block algorithm and are available to other
function blocks, e.g. the PID block, as a starting variable for connecting the desired application
function.
Using the
Discrete Output function block (DO)
, various actions and functions can be initiated
and controlled via FOUNDATION Fieldbus in the device functions Promag 55 FOUNDATION
Fieldbus.

Note!
Other function blocks such as the PID, Arithmetic, Input Selector, Signal Characterizer and
Integrator function block are described in the "FOUNDATION Fieldbus Overview" (BA013S)
