I have implemented Modbus protocol as a client for multiple read (function code 0x04) and multiple write (Function code 0x10). I have used keil and IC P89C61X2 
I have tested with Modbus simulator software and it works perfectly.

I have informed simulator supplier about this.&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/87617?ContentTypeID=1</link><pubDate>Mon, 19 Jun 2006 11:08:02 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:077b521f-bd43-479b-b7bd-2318ad1f6988</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;i&gt;&amp;quot;I have tested with Modbus simulator software and it works perfectly.&amp;quot;&lt;/i&gt;&lt;br /&gt;
&lt;br /&gt;
So, it looks like the simulator is faulty, then?&lt;br /&gt;
&lt;br /&gt;
I hope you have advised the supplier...&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/45700?ContentTypeID=1</link><pubDate>Fri, 16 Jun 2006 21:19:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:35167c60-5f89-430e-ae40-ca83fa4aec27</guid><dc:creator>Shashank Raut</dc:creator><description>&lt;p&gt;I have not received any help from this forum but now I found the fault and this problem is solved.&lt;br /&gt;
The problem was with the parity bit sent by microcontroller, I have removed the bug with parity bit setting logic and it started working!!!!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
