<h2 id="description">Description</h2>
<p><code>axopen.components.keyence.vision</code> provides AXOpen control components for
<a href="https://www.keyence.com/">Keyence</a> industrial vision and code-reading
hardware over PROFINET. It encapsulates the cyclic I/O exchange,
trigger/result handshakes, and result-data parsing required to use these
devices from a SIMATIC AX application.</p>
<p>The package ships:</p>
<ul>
<li>A <strong>PLC library</strong> (<code>@inxton/axopen.components.keyence.vision</code>) — control
components and data types.</li>
<li>A <strong>.NET twin</strong> (<code>AXOpen.Components.Keyence.Vision</code>) — runtime mirror of
the PLC types for orchestration and visualization. The <code>Axo_IV3</code> twin
additionally exposes a reverse-proxy helper that surfaces the device's
built-in HTTP live view inside the application's web UI.</li>
<li>A <strong>Blazor package</strong> (<code>AXOpen.Components.Keyence.Vision.blazor</code>) — UI
rendering. The components render via the generic <code>RenderableContentControl</code>
pattern, with a dedicated <code>Axo_IV3View</code> available when richer visualization
is required.</li>
</ul>
