The gross value (hex:000004D2 <=> 1234) can be read from bytes 03.
When the "Overload", "Test Active" or "ADC error" bits are set, the read value is invalid.
Negative values are output in the second complement.
12.2.5 Special hints for DeviceNet and EtherNet-IP
With these eldbus 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 rmware.
Sequence of bytes 03, e.g.with device type and software version, see table below.
Standard sequence Sequence for DeviceNet and EtherNet-IP
Byte 0 TYPE MSB Byte 0 SUBVERSION
Byte 1 TYPE LSB Byte 1 MAIN VERSION
Byte 2 MAIN VERSION Byte 2 TYPE LSB
Byte 3 SUBVERSION Byte3 TYPE MSB
Consequently, the sequence on the PLC side must be changed when using the DeviceNet
and EtherNet–IP eld bus types.
