&lt;/h2&gt;&lt;p&gt;ZE is a network debugging tool built specifically for Zenoh networks. It provides a graphical interface to:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Subscribe to key expressions and monitor real-time data flows&lt;/li&gt;
&lt;li&gt;Publish data to the network for testing and debugging&lt;/li&gt;
&lt;li&gt;Browse the network data topology in real-time&lt;/li&gt;
&lt;li&gt;TODO: Query specific data from the network&lt;/li&gt;

&lt;h2 id="mtconnect-agent-and-adapter"&gt;MTConnect Agent and Adapter
&lt;/h2&gt;&lt;p&gt;A full MTConnect standard implementation: a data generator, an SHDR adapter, and a REST agent, wired together to simulate and serve real-time manufacturing equipment data end to end.&lt;/p&gt;
&lt;h3 id="key-features"&gt;Key Features
&lt;/h3&gt;&lt;ul&gt;
&lt;li&gt;Full MTConnect 2.0-2.4 compliance across all required endpoints and protocols&lt;/li&gt;
&lt;li&gt;SHDR protocol implementation with heartbeat and streaming&lt;/li&gt;
&lt;li&gt;REST API with the standard MTConnect HTTP interface and XML responses&lt;/li&gt;
&lt;li&gt;Realistic CNC machine data generation using elliptic curve algorithms&lt;/li&gt;
&lt;li&gt;Web UI for configuration and system control&lt;/li&gt;
&lt;/ul&gt;
&lt;h3 id="usage"&gt;Usage
&lt;/h3&gt;&lt;div class="highlight"&gt;&lt;div class="chroma"&gt;
&lt;table class="lntable"&gt;&lt;tr&gt;&lt;td class="lntd"&gt;

&lt;/div&gt;
&lt;/div&gt;&lt;p&gt;Then browse to &lt;code&gt;/current&lt;/code&gt;, &lt;code&gt;/probe&lt;/code&gt;, or &lt;code&gt;/sample?count=10&lt;/code&gt; on the agent, or &lt;code&gt;/config&lt;/code&gt; for the web UI.&lt;/p&gt;</description></item></channel></rss>
