What Cancellation means for you

You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.

How ECS defines Cancellation · all four lifecycle stages

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 CJ1W-SCU31-V1 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
