As an alternative, register address 40001 is also available as start
address (function code 03).
The actual measured values are transmitted as signed data compris-
ing two octets. This means that the value range encompasses max.
+32768 to -32767. In addition to the measured value, the status of the
measured value is delivered in a second register word.
