But walk into a North American plant and you&rsquo;re far more likely to find an Allen-Bradley PLC — a ControlLogix in the big cells, a CompactLogix on the smaller machines, maybe a dusty SLC 500 still running a line nobody dares touch. And Allen-Bradley doesn&rsquo;t speak OPC-UA out of the box. It speaks <strong>EtherNet/IP</strong> and <strong>CIP</strong>. This is the guide to bridging that gap with Node-RED.</p>
