Up to 4 bytes (Data 1 ... Data 4) are available for parameter data.
• Data is entered in flush left Intel format with Data 1 as LSB and Data 4 as MSB (see example).
Example:
Transmitting the value “20” for a code in Fixed32 data format.
• Fixed32 is a fixed-point format with 4 decimal places, accordingly, the value has to be
multiplied by 10000.
