What Total Discontinuation means for you

The manufacturer has finished with the part. You may still find one through surplus or refurbished sellers, or in another site's stores, but that is not a supply chain. Knowing where your units are, and where a spare might be, is what shortens the stoppage when one fails.

Before replacing a communications module

A communications module can stop a much larger part of the machine than its size suggests. We would document the protocol, node or IP addressing, rack configuration, connected devices and every PLC, HMI or SCADA dependency that references it.

If the migration changes network technology, the scope has to include the equipment at the other end of that link as well as the module itself. Capturing the topology now turns a future fault into a controlled network change rather than a discovery exercise.

Know where every unit is before one fails.

A Capture audit finds every 1747-SN on your site, photographs it where it sits and checks it against manufacturer lifecycle status, so you know your exposure and where your spares are before a failure stops a line.

  • Every device located, photographed and lifecycle-checked
  • Findings report, plus a populated Command Centre
  • No production downtime
