Is the Mitsubishi Electric FX0N-24MR-ES discontinued?
On ECS's lifecycle assessment, the FX0N-24MR-ES is discontinued and no longer supplied by Mitsubishi Electric.
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 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. When a unit fails, your options are to find one and restore the program onto it, or to migrate the machine.
Both routes start in the same place: having the program. Without a backup, a found spare is just hardware.
How ECS defines Total Discontinuation · 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 FX0N-24MR-ES
Is the Mitsubishi Electric FX0N-24MR-ES discontinued?
On ECS's lifecycle assessment, the FX0N-24MR-ES is discontinued and no longer supplied by Mitsubishi Electric.
Can I still buy a FX0N-24MR-ES?
Not from Mitsubishi Electric. Surplus and refurbished sellers may have stock; check provenance and test before fitting.
How do I back up a FX0N-24MR-ES?
It is programmed with GX Developer. 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 FX0N-24MR-ES 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
