Hitachi WJ200-001S Instruction Manual page 584

Example 2-2: When writing 32-bit data with Little Endian : As same as example 2-1, where 3000 sec is
written as the Acceleration time (1) (F002, register number = 1103h) in an inverter having slave address
one, the data resolution of the Holding register is 0.01sec, so the data to be written is 300000d=000493E0h.
But the arrangement of the data is different from the previous example.
Query:
No Field Name
1 Slave address
2 Function code
3 Start address (high byte)
4 Start address (low byte)
5 Number of holding
registers (high byte)
6 Number of holding
registers (low byte)
7 Byte number
8 Change data 1 (high byte)
9 Change data 1 (low byte)
10 Change data 2 (high byte)
11 Change data 2 (low byte)
12 CRC-16 (high byte)
13 CRC-16 (low byte)
Notice the data from eighth to eleventh.
Write data (Change data 1, 2) are subject to the Endian function.
(As for the data arrangements of Little Endian, please refer to "[2] How data are arranged by each
endian.")
