PLC

Keep the line running. Source the part in hours.

Packaging lines, skid cells, and 30-year-old PLC racks fail in the same way — the line stops and procurement spends the day on the phone. Specsmith reads the rack, lands the verified MPN, and routes the shipment to a supplier with stock today, so the line comes back up before the shift ends.

The bench problem

01Counterfeit risk

Surplus channels re-label and re-shell modules faster than any in-house QA can catch. Specsmith ships every match with a verified supplier and the manufacturer-issued manual — no unmarked boxes, no mystery sellers.

02Hard-to-source parts

A vintage PLC module sits in one surplus stockroom across the country. The /xref workflow joins it against the rest of the catalog so a crew always sees a drop-in substitute — Allen-Bradley ladder swap, Siemens S7-200→S7-1200 path, Modicon M340 — even when the part itself is gone.

03Downtime cost

Every hour a packaging line is idle costs more than the spare. /predict reads the vibration signature on the next critical asset so the crew pulls the part during scheduled downtime, not in the middle of the production run.

The same Identify workflow that runs the homepage, pinned to the PLC rack — read the nameplate, land the matched SKU, and source the verified spare without leaving the panel.

PLC teams on Specsmith

What crews on packaging lines and skid cells say.

We replaced a six-week phone-and-email round for a discontinued Allen-Bradley module with a single photo. The shipment confirmation closed the loop the same afternoon.

Specsmith reads the legacy Siemens plates nobody on the team can read by eye anymore. The hit list for spares is shorter and the substitutes are real drop-ins.

We caught a CompactLogix drift on a packaging line three weeks before the alarm would have. Pulled the spare during planned downtime, not at 2am.
