ASDA-A2 Chapter 9 Communications
9-12 Revision February, 2017
Before and after the transmission in RTU mode, 10ms of silent interval is needed.
Example 3: function code 10H, write multiple words:
The Master issues command to the 1
st
Slave and writes 0BB8H and 0000H to the starting address
0112H. That is to say, 0112H is written into 0BB8H and 0113H is written into 0000H. The
maximum allowable data in one single access is 10. The Slave sends the response message to
the Master after the writing is completed. The calculation of LRC and CRC will be described in next
chapter.
