<p>NModbus is a C# implementation of the Modbus protocol.
Provides connectivity to Modbus slave compatible devices and applications.
Supports serial ASCII, serial RTU, TCP, and UDP protocols.</p>
<h1 id="history">History</h1>
<p>The NModbus4 project appears to have gone quiet. This is a fork of that project.</p>
<ul>
<li>NModbus is a fork of NModbus4 (<a href="https://github.com/NModbus4/NModbus4">https://github.com/NModbus4/NModbus4</a>).</li>
<li>NModbus4 is fork of NModbus(<a href="https://code.google.com/p/nmodbus">https://code.google.com/p/nmodbus</a>).</li>
</ul>
<p>NModbus differs from NModbus4 in following:</p>
<ul>
<li>Modbus slave devices are now added to a network which is represented by <code>IModbusSlaveInstance</code>.</li>
<li>Heavier use of interfaces.</li>
<li>Custom function code handlers can be added to slave devices.</li>
</ul>
<h1 id="goals">Goals</h1>
<ul>
<li>Improve Modbus Slave support (e.g. support multiple slave devices on the same physical transport).</li>
</ul>
<h1 id="install">Install</h1>
<p>To install NModbus, run the following command in the Package Manager Console</p>
<pre><code>PM&gt; Install-Package NModbus
