Omron CJ2M · Modular CPU

Omron CJ2M-CPU14

Omron is retiring the CJ2M-CPU14. It can still be ordered, so this is the time to plan, not panic.

  1. Active RolloutSold and supported normally
  2. Phase OutRetirement announced, still orderable
  3. CancellationNormal sale ended, spares may remain
  4. Total DiscontinuationNo manufacturer supply or repair

ECS stage: Phase Out. Omron's published term: Discontinuation notice; final order entry end of June 2027.

Is the Omron CJ2M-CPU14 being discontinued?

Yes. The CJ2M-CPU14 is in phase-out (discontinued September 2027, last-time-buy June 2027): still orderable for now, but on its way out. Its successor is the CJ3M-CPU14.

What Phase Out means for you

The manufacturer is retiring the part, but you can still buy it. Nothing needs ripping out. Four things are worth doing while it is still easy: find every unit you run, make sure each has a current backup, decide whether to hold spares, and price the move to the CJ3M-CPU14.

How ECS defines Phase Out · all four lifecycle stages

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 CJ2M-CPU14

Is the Omron CJ2M-CPU14 being discontinued?

Yes. The CJ2M-CPU14 is in phase-out (discontinued September 2027, last-time-buy June 2027): still orderable for now, but on its way out. Its successor is the CJ3M-CPU14.

What replaced the CJ2M-CPU14?

Omron lists the CJ3M-CPU14 as the successor. Check compatibility with your machine before planning the change.

Can I still buy a CJ2M-CPU14?

Yes, through normal channels during the phase-out period. It is the cheapest point to buy any spares you want to hold.

How do I back up a CJ2M-CPU14?

It is programmed with CX-Programmer. 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 CJ2M-CPU14 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
