Analog Output module
Transmit compensation values from the automation system to the measuring device.
Analog Output modules cyclically transmit compensation values, along with the status and
the associated unit, from the automation system to the measuring device. The
compensation value is depicted in the first four bytes in the form of a floating point
number as per the IEEE 754 standard. The fifth byte contains standardized status
information pertaining to the compensation value. The unit is transmitted in the sixth and
seventh byte.
Assigned compensation values
The configuration is performed via: Expert → Sensor → External compensation
Slot Compensation value
18 External pressure
19 External temperature
20 External reference density
29 External value for % S&W (sediment and water)
30 External value for % Water cut
1) Only available with the Petroleum application package.
