In practice, plants regularly slip to five or seven days. When project managers look for the root cause, mechanical issues account for a small share; the majority is wiring, terminations, and analyzer configuration.<\/p>\n<p>The problem isn&rsquo;t that field technicians lack skill. It&rsquo;s that every project treats wiring as bespoke \u2014 different cable specifications, different pin assignments, different terminal blocks in every panel. Multiply that by twelve analyzers on a skid and the commissioning day becomes a puzzle rather than a checklist.<\/p>\n<h2 id=\"what-plug-and-play-actually-means\"><span class=\"ez-toc-section\" id=\"What_%E2%80%9Cplug-and-play%E2%80%9D_actually_means\"><\/span>What &ldquo;plug-and-play&rdquo; actually means<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Plug-and-play wiring is not a single feature.
