WARNING
The structure of Data Objects (PDO and SDO) requires bytes to be
sent from the Least Significant Byte (LSB) to the Most Significant
Byte (MSB).
On the contrary in TwinCAT write and read data from MSB to LSB.
Furthermore in TwinCAT also strings must be entered in the reverse
order:
 read default values: Data byte = 64 61 6F 6Chex = "daol" in ASCII
code (means "load" in reverse);
 save parameters: Data byte = 65 76 61 73hex = "evas" in ASCII
code (means "save" in reverse).
