<script type="text/x-red" data-help-name="xilica-subscribe">
  <p>Builds <code>SUBSCRIBE</code> or <code>UNSUBSCRIBE</code> commands for a Xilica Solaro processor.</p>
  <p>On each input message, the node sets <code>msg.payload</code> to one or more commands separated by carriage returns. Wire the output into a <code>xilica-command</code> node to send them over TCP.</p>
  <p><strong>Action</strong> selects whether to generate <code>SUBSCRIBE</code> or <code>UNSUBSCRIBE</code> commands.</p>
  <p><strong>Rules</strong> define which control names to generate, similar to the Switch node's rule list:</p>
  <ul>
    <li><strong>Type ==</strong>: the Value field is used as a full control name (e.g. <code>MASTER_GAIN</code>).</li>
    <li><strong>Type Indexed</strong>: the Value field is a base string (e.g. <code>CH</code>), and the From/To fields define a numeric range (e.g. 1–48 → <code>CH1</code>…<code>CH48</code>).</li>
  </ul>
  <p>The Transport field controls the subscription transport string, typically <code>TCP</code>. The node generates commands like <code>SUBSCRIBE CH1 "TCP"</code>.</p>
