Is the Rockwell 1756-ENBT discontinued?
On ECS's lifecycle assessment, the 1756-ENBT has been cancelled (since December 2021): no longer sold as a current product, though spares may remain available for a period.
Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.
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.
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.

Common questions about the 1756-ENBT
Is the Rockwell 1756-ENBT discontinued?
On ECS's lifecycle assessment, the 1756-ENBT has been cancelled (since December 2021): no longer sold as a current product, though spares may remain available for a period.
Can I still buy a 1756-ENBT?
Not as a normal new product. Remaining distributor stock or designated spares may still be available. Buy any you need now.
Know where every unit is before one fails.
A Capture audit finds every 1756-ENBT 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
