What is this &amp;quot;HMI&amp;quot; that you keep on about?&lt;/p&gt;

&lt;p&gt;
Is it something that you&amp;#39;ve written yourself, or is it from some
3rd party?&lt;/p&gt;

&lt;p&gt;
If it&amp;#39;s something that you&amp;#39;ve written yourself, then it&amp;#39;s
obviously up to &lt;i&gt;&lt;b&gt;you&lt;/b&gt;&lt;/i&gt; to debug what &lt;i&gt;&lt;b&gt;you&lt;/b&gt;&lt;/i&gt;
have written!&lt;/p&gt;

&lt;p&gt;
If it&amp;#39;s from some 3rd party, then you should contact them for
support - maybe they intended it to work that way...?&lt;/p&gt;

Start anew: what is the problem? slowly and clearly - what does
not work?&lt;/p&gt;

hello sir&lt;br /&gt;
thanks for for reply.&lt;br /&gt;
i am using modbus RTU 984 format and i followed the pdf of it and
wrote the code. now i am facing problem in 0x10 function code. after
replying HMI again sends 0x01 0x00 0x00 0xdf. which is this string.
this protocol supports 0x10 function code but still i have the
problem.&lt;br /&gt;
i am using rs-422 communication and it is working fine as my other
code for function code is working well.&lt;br /&gt;
any information do you require?&lt;br /&gt;
thank you&lt;br /&gt;
regards&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: modbus protocol</title><link>https://community.arm.com/thread/58842?ContentTypeID=1</link><pubDate>Thu, 04 Nov 2010 01:18:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:629f8d0c-27f5-4b94-9d9d-d487c9bdc9dc</guid><dc:creator>Tamiryan Michael</dc:creator><description>&lt;p&gt;&lt;p&gt;
MODBUS implementations are typically very different from one
another, and to make things even worse - you provided no details
whatsoever! It&amp;#39;s like saying: &amp;quot;My car does not start. What is wrong?&amp;quot;
while refusing to go to a garage...&lt;/p&gt;
