B.2
Derived measurement data
Derived measurement data associated with each of the four possible transducer positions is
available in a block of input registers that can be read using Modbus function code 04.
Analogue input data
Analogue input data from the two external mA inputs is available in a block of input registers
that can be read using Modbus function code 04.
