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:
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.")
