1.2 Data format
Multi−byte values are usually interpreted by CMAX in the byte
sequence INTEL (LSB−MSB)".
INTEL (LSB−MSB) − little endian
Example 21.268.514

If your control system uses another byte sequence, you must
take this into consideration accordingly, e.g. in your applica 
tion programs.
CPX parameter Analogue process value representation"
A few CPX nodes (e.g. CPX−F B13, FB33, FB34 and FB35) sup
port the global system parameter Analogue process value
representation" (system table function number 4402, bit 7):
 Value 0": INTEL (LSB−MSB)  default
 Value 1": MOTOROLA (MSB−LSB)
MOTOROLA (MSB−LSB) − big endian
