Schneider Electric Modicon TSXP57304M CPU – Mid-range controller for Modicon Premium automation racks

The Schneider Electric Modicon TSXP57304M is a reliable mid-range CPU for the Modicon Premium platform, typically used in machine control, packaging lines, materials handling, and process skids. From my experience, it strikes a nice balance of scan performance, flexible task scheduling, and broad protocol support—without forcing you into unnecessary extras. You might notice that it integrates smoothly with existing TSX Premium racks, power supplies, and I/O, which makes brownfield upgrades very straightforward.

• Express options: FedEx, UPS, DHL

Key Features

• Modicon Premium rack CPU: Fits TSX Premium backplanes, so you can reuse existing TSX power supplies and I/O modules.
• Deterministic control tasks: Cyclic, fast, and event tasks help keep motion steps, interlocks, and safety interlocks responsive in most cases.
• IEC 61131-3 languages: Ladder, Structured Text, Function Block, and SFC—ideal when teams prefer mixed-language projects.
• Onboard serial communications: TER and AUX service/field ports for Modbus/Unitelway over RS232/RS485, typically enough for HMIs, drives, and service tools.
• Removable memory card support: PCMCIA memory card for program backup and fast recovery; one thing I appreciate is how quickly you can swap a CPU and restore.
• Integrated diagnostics: Clear status LEDs and system bits for quick fault tracing; seems to reduce commissioning time in many cases.
• Flexible I/O architecture: Works with local TSX modules or networked I/O through add-on communication modules.
• Tooling compatibility: Programmed with PL7 Pro; many sites also run Premium CPUs under Unity Pro / EcoStruxure Control Expert with the appropriate firmware.

• TSXETY4103 – Ethernet TCP/IP communication module when you need native Ethernet networking and SCADA links.
• TSXPSY series – Premium power supplies; pick current rating based on total rack load.
• TSX RKY 4/6/8/12 – Modicon Premium racks (4–12 slots) for CPU, comms, and I/O modules.
• Premium I/O modules – Discrete (TSX DMZ), analog (TSX AEY/ASY), motion and specialty modules as required.
• Memory card (PCMCIA) – For application backup and firmware files; handy for field swaps.

Installation & Maintenance

• Cabinet & environment: Install in a ventilated industrial cabinet (IP54 or better is typical). Keep ambient 0–60 °C and humidity non-condensing.
• Mounting: Seat the TSXP57304M firmly in a TSX RKY rack; secure end stops; maintain clearance for airflow on top/bottom.
• Wiring & grounding: Use shielded twisted pair for serial lines; bond shields at one end; ensure clean protective earth for the rack.
• EMC practices: Separate power and signal wiring, route field cables away from VFD outputs, and add ferrites if you see sporadic comms noise.
• Backup & battery: Keep a recent program backup on the memory card; replace the CPU backup battery at recommended intervals to protect retentive data.
• Firmware & tools: Update firmware during scheduled downtime; verify toolchain compatibility (PL7 Pro or Unity Pro / EcoStruxure Control Expert) before upgrading.
• Routine care: Quarterly dust removal with dry air, check terminal integrity, and review diagnostic logs for early warning signs.

Quality & Certifications

• Certifications: CE, UL, CSA, RoHS (typical for Modicon Premium family; exact markings vary by CPU revision)
• Manufacturer’s policy: Standard Schneider Electric quality processes and traceability
• Warranty: 365 days (provided by our sales channel as stated above)

Field note: A packaging OEM told us the TSXP57304M was “predictable and easy to service”—they liked that a spare CPU plus a memory card got a downed line running again in minutes.
