Note:
Before and after transmission in RTU mode, 10 ms of silent interval is needed.
Example 3: function code10H, writing multiple words:
The master issues command to the 1
address 0112H. That is to say, 0BB8H is written into 0112H and 0000H is written into 0113H. 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
the following section.
