The gross value (hex:000004D2 <=> 1234) can be read from bytes 0
3.
When the "Overload", "Test Active" or "ADC error" bits are set, the read value is invalid.
Negative values are output in the second complement.

Special hints for DeviceNet and EtherNet-IP
With these fieldbus types, the sequence of the bytes (only applicable for words and
individual bytes) is inverted.
With long words, this problem does not arise due to compensation by the firmware.
Sequence of bytes 0

Consequently, the sequence on the PLC side must be changed when using the DeviceNet
and EtherNet–IP field bus types.
