4.3 Process Data
4.3.1 Overview of Sensor Types
The following table serves as an overview of all supported sensor types. The
following sections contain detailed information about the individual sensor types.
The information provided in the respective tables on the resolution of the
measured values and the raw value ranges yielded from this are based on
manufacturing scaling.
ID Sensor type Measurement range
0 0 … 20 mA 0 … +20 mA
1 4 … 20 mA +4 … +20 mA
2 3.6 … 21 mA +3.8 … +20.5 mA
4.3.2 Standard Format
4.3.2.1 Sensor Type 0 … 20 mA
For the current measurement with sensor type 0 … 20 mA, the input range of
0 … +20 mA is mapped to a process value rage of 0 … +32767. The current
underranges and overranges refer to manufacturer range violations.
