プリセット複数レジスタ (FC=16)

要求

このコマンドは、レジスタ＃40002と40003を保持する2つのアナログ出力の内容をアドレス17のスレーブデバイスに書き込んでいます。

11 10 0001 0002 04 000A 0102 C6F0

11: The Slave Address (11 hex = address17 )
10: The Function Code 16 (Preset Multiple Registers, 10 hex - 16 )
0001: The Data Address of the first register. 
( 0001 hex = 1 , + 40001 offset = register #40002 )
0002: The number of registers to write 
04: The number of data bytes to follow (2 registers x 2 bytes each = 4 bytes)
000A: The value to write to register 40002 
0102: The value to write to register 40003 
C6F0: The CRC (cyclic redundancy check) for error checking.
