4.3. Example of Extracting Measured Data This shows how to count bit numbers in the MX118. With Big Endian, from the start of the data field, starting with the msb of the MSB, bit numbers decrease in units of bytes or bits from left to right. The first bit number of the data field is always 63. For Llittle Endian, from the start of the data field, starting with the msb of the LSB, bit numbers increase in units of bits from right to left, and in units of bytes from left to right.
Data Field Length = 8 Bytes For Big Endian: Available start bit position settings: 0–(Bit Length-1) 63・・・・・・56 55・・・・・・48 47・・・・・・40 39・・・・・・32 31・・・・・・24 23・・・・・・16 15・・・・・・8 7・・・・・・0 Byte 7 Byte 6 Byte 5 Byte 4 Byte 3 Byte 2 Byte 1 Byte 0 bit lsb For Little Endian: Available start bit position settings: 0–(64-Bit Length) 7・・・・・・0 15・・・・・・8 23・・・・・・16 31・・・・・・24 39・・・・・・32 47・・・・・・40 55・・・・・・48 63・・・・・・56 Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 bit lsb Th
