  <h3>Details</h3>
  <p>
    This node aggregates received SICK TDC gateway data among 30- or 60-second
    intervals (depending on the setting of <em>Interval</em>) and converts it to a
    format understood by the oee.ai connector node.
  </p>
  <p>
    The node provides one input expecting SICK TDC digital I/O data as sent by the
    gateway device via WebSocket. As such, this node does <em>not</em> take care of
    the connection to the gateway itself. Instead, the data sent by the TDC device
    must be made available to this node via the <code>msg.payload</code> property.
    This can, for example, be accomplished by routing the output of a
    <em>WebSocket in</em> node (available on Node-RED by default) to the input of this
    node. The WebSocket URL to receive the expected digital I/O data from could look like
    this: <code>ws://192.168.0.100:32869/ws/tdce/dio/states</code>. The correct IP
    address and port for the WebSocket connection can be obtained from the configuration
    of the SICK TDC device. Note that you have to be connected to the device&apos;s
    network for a WebSocket connection to be established.
  </p>
  <p>
    The node provides four outputs corresponding to the first four digital inputs
    provided by a SICK TDC gateway. On each output, a <code>msg</code> object holding the
    properties <code>count</code>, <code>from</code> and <code>to</code> (as required
    by the oee.ai connector node) is sent every 30 or 60 seconds (depending on this
    node&apos;s configuration). If no data is received for a specific SICK TDC input
    in a 30- or 60-second interval, <code>msg.count</code> is set to 0 for the
    according output for that timeframe.
