Example 2: When writing 32-bit data
Example 2-1: When writing 32-bit data with Big Endian:
A Query that can write 3000sec as the Acceleration time (1) (F002, register number = 1103h) in an inverter
having slave addresses one (the data resolution of this Holding register is 0.01sec, thus
300000d=000493E0h) is:
Query:
No
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 data1, 2) are subject to the Endian function.
(As for the data arrangements of Big Endian, please refer to "[2] How data are arranged by each endian.")
