Schneider Electric TSX P57 2634M

Discontinued (family since 2018)

Analysis reviewed: September 11, 2026

What should replace this part?

The documented replacement is Modicon M580 family (via UMAC tool). This is a platform migration, not a drop-in swap.

Check UMAC import eligibility first, then weigh the M580 move against bridge stock

Your options

Source a used unit
Surplus dealers list 2634M-class Premium CPUs. Confirm price, condition, and firmware before planning around used stock.
Migrate to Modicon M580 with UMAC
Schneider Electric's UMAC tooling carries eligible PLCs to the M580 family, with rack, wiring, and I/O re-engineering.

What will need to change?

SoftwareThe PL7 program moves to Unity Pro / EcoStruxure Control Expert through UMAC — but only for eligible CPUs (P57 30x/40x with OS V5.6 or later).
HardwareA new chassis and rack replace the old ones. Re-do the field wiring.
I/ORe-engineer the I/O for the M580 family.

For anything not listed here, check the replacement manual against your existing configuration.

Technical evidence

The recommendation above is based on the sources listed here. OEM source means the manufacturer published it; third-party source means a distributor, repair company or reseller states it. Confidence reflects how directly those sources support the recommendation: High — directly supported by manufacturer documentation. Medium — supported by family-level, secondary, or otherwise less-direct evidence. Low — limited or indirect evidence; verify independently before ordering.

OEM / manufacturer sources

OEM source Confidence: Low Schneider Electric migration doc + stockist reports
The manufacturer document lays out Premium-to-M340/M580 paths, and surplus dealers list the 2634M class.
Source excerptPremium->M580/M340 migration options; exact-model surplus stock listed
View source · Note: The manufacturer document was not opened directly. The stock claim is dealer-level, and exact UMAC coverage for this CPU is unconfirmed.

Third-party sources

Third-party source Confidence: Low Industrial Monitor Direct (independent technical publisher) · 2026-07-09
Import eligibility is narrow: only P57 30x/4xx CPUs with OS V5.6 or later import into Unity/Control Expert.
Source excerpt30x/4xx + OS V5.6+ importable; older Premium CPUs remain on PL7; check OS banner
View source · Note: Check your CPU and OS version against the manufacturer matrix.
Third-party source Confidence: Low Nardy Automation (stockist)
Surplus dealers list 2634M-class Premium CPUs, so a used channel exists — but price and condition are unconfirmed.
Source excerptTSX P57 1634M/2634M/3634M CPUs plus DEY/DSY I/O carried
View source · Note: Availability snapshot only. An exact-2634M listing still needs confirming.

Limitation: Confirm your exact CPU and OS version against the import rule, and confirm any used listing at the exact-model level, before committing.
