The Schneider Electric Modicon Premium TSX P573634M (also referenced as TSX-P57-3634M or UNY 573X4) is a central processing unit for the Modicon Premium automation platform. This processor provides high execution speed, multitasking capabilities, and integrated communication ports for demanding industrial control applications.
CPU type: 32-bit RISC microcontroller. Program memory: 1024 KB (user application). Data memory: 384 KB. Execution speed: 0.1 µs per boolean instruction. The processor supports up to 8 tasks: 1 master, 1 periodic, and 6 event tasks. Real-time clock with battery backup for timestamping.
Built-in ports: 1x Modbus RS-485 (non-isolated), 1x USB programming port, 1x Ethernet TCP/IP interface (10/100 Mbit/s) with embedded web server. Ethernet supports Modbus TCP, DNP3, and SNMP. The processor can also serve as a gateway between fieldbus networks when used with communication modules.
Up to 2048 local I/O points via TSX I/O modules (hardware configuration). Supports remote I/O via Fipio, Profibus DP, or DeviceNet using optional coprocessor modules. Maximum 16 racks per configuration. Hot standby capability with redundant CPU option.
Compatible with Schneider Electric EcoStruxure Control Expert (formerly Unity Pro) software. Programming languages: LD, FBD, SFC, ST, IL. The processor supports user-defined function blocks and DFB (Derived Function Blocks). Online debugging and forced I/O are available via USB or Ethernet.
Operating temperature: 0°C to 60°C. Storage: -40°C to 85°C. Relative humidity: 5% to 95% non-condensing. Protection class IP20. Mounting on TSX Premium rack (backplane). Power consumption: 360 mA at 5V DC from backplane. Weight: 0.6 kg.

LED indicators: Run, Stop, ERR, IO, ETH, and battery low. Built-in watchdog timer with configurable timeout. Hardware test at startup (memory, I/O bus). The processor supports password protection and application lock to prevent unauthorized modifications. Hardware ID ensures traceability.
Typical for process industries, water treatment, material handling, and building automation. The TSX P573634M excels in systems requiring deterministic response and medium to large I/O counts. Its Ethernet port enables SCADA connectivity without additional gateways.
The Schneider Modicon Premium TSX P573634M CPU offers a robust and flexible control solution for legacy and new installations. With multitasking and native Ethernet, it remains a competitive choice for mid-to-high end PLC applications.
