Block configuration when device is delivered
The block model shown below illustrates the block configuration when the device is
delivered.

Fig. 27: Block configuration when device is delivered
The Pressure Transducer Block supplies the primary value depending on the measuring
mode, and a secondary value
• for Cerabar/Deltapilot, secondary value = sensor temperature.
• for Deltabar, secondary value = Measured pressure.
By means of the Channel/CHANNEL parameter, the measured values (primary value,
secondary value, etc.) are transferred to an Analog Input Block from the Transducer Block,
see also the following section).
The Discrete Output, PID, Arithmetic, Signal Characterizer and Input Selector Block are not
connected in the as-delivered state (IT, DI).
Deltabar M:
In the DP_FLOW Transducer Block, the flow is totalized in the "Flow" measuring mode and
output by means of the Totalizer 1/TOTALIZER_1 parameter.
