INFORMATION
The 32-bit data (error status, DigOuts, DigIns) has been broken down into 16-bit data because
the data width of the fieldbuses is limited to 16-bit in some places.
If 32-bit data access is possible, the 32-bit word is used regardless of whether the low or high
word is being accessed!
IMPORTANT INFORMATION
The REAL depiction is the standard IEEE format
(Help: 50 % target value = 0X42480000)
The endianness of the fieldbus should be observed for all data types.
