Assigned compensation values
A compensation value is permanently assigned to the individual Analog Output blocks.
Function block Compensation value
AO 1 External pressure
1)
AO 2 External temperature
1)
AO 3 External reference density
AO 4 External S&W percentage
2)
AO 5 External water cut percentage
2)
1) The compensation values must be transmitted to the device in the SI basic unit
2) Only available with the Petroleum application package
The selection is made via: Expert → Sensor → External compensation

DI module (Discrete Input)
Transmit discrete input values from the measuring device to the PROFIBUS master (class
1). Discrete input values are used by the measuring device to transmit the state of device
functions to the PROFIBUS master (class 1).
The DI module cyclically transmits the discrete input value, including the status, to the
PROFIBUS master (class 1). The discrete input value is depicted in the first byte. The
second byte contains standardized status information pertaining to the input value.
Two Discrete Input blocks are available (slot 15 to 16).
Selection: device function

Empty pipe detection
• 0 (device function not active)
• 1 (device function active)
Low flow cut off
