Is the Rockwell 1762-L40BXB discontinued?

The 1762-L40BXB has been cancelled (since August 2021): no longer sold as a current product, though spares may remain available for a period.

Source: Rockwell Automation. 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 and whether each has a backup.

Before replacing a PLC processor

We would secure a current, tested PLC program backup, record the programming software and version, and map the I/O, networks and intelligent modules connected to the controller.

CPU migrations can alter addressing, communications, memory behaviour or firmware requirements, so a newer processor in the same general family is not automatically a drop-in replacement. Proving that the program can actually be restored while the existing controller still runs is one of the most valuable checks a maintenance team can make.

Common questions about the 1762-L40BXB

Is the Rockwell 1762-L40BXB discontinued?

The 1762-L40BXB has been cancelled (since August 2021): no longer sold as a current product, though spares may remain available for a period.

Can I still buy a 1762-L40BXB?

Not as a normal new product. Remaining distributor stock or designated spares may still be available. Buy any you need now.

How do I back up a 1762-L40BXB?

It is programmed with RSLogix 500. The exact software version and cable depend on the unit's firmware. ECS records both for every unit it captures, alongside a verified backup.

With a backup, a failed unit is hours. Without one, it is days.

A Capture audit finds every 1762-L40BXB on your site, takes a backup of each one it can reach, and records the software version and cable needed to restore it. When a discontinued unit fails and a replacement turns up, the program is ready to load.

  • Every device located, photographed and lifecycle-checked
  • Backups taken on the day, with software version and cable recorded
  • Findings report, plus a populated Command Centre
  • No production downtime
