Product Overview
When your automation system demands fast, reliable control in a compact footprint, the Schneider TSXP57203M delivers. Part of the TSX Micro PLC series, this processor integrates Ethernet TCP/IP via RJ45 and a serial link 2 female mini DIN RS485 interface running at 19.2 kbit/s. It handles up to 512 discrete I/O and 24 analog I/O points, making it suitable for mid-range machine control and process applications. With a fast task overhead of 0.3 ms and a master task overhead of 1 ms, the TSXP57203M ensures quick response to critical events.
Technical Specifications Breakdown
Processing Performance
Execution time per instruction reaches 0.19 µs for Boolean operations without a PCMCIA card and 0.25 µs with the card. The processor achieves 3.71 Kinst/ms (65% Boolean + 35% fixed arithmetic) without the PCMCIA card and 2.1 Kinst/ms with it. This performance suits applications requiring moderate scan cycles and deterministic control.
Memory and Storage
Internal RAM provides 224 KB program and 96 KB data when using a PCMCIA card; without the card, 96 KB program and data are available. An additional 256 KB data storage is possible via the PCMCIA card. The application structure includes 1 master task, 1 fast task, and 32 event tasks, allowing flexible program organization.
Power and Connectivity
Current consumption is 1650 mA at 5 V DC. The processor supports up to 2 communication modules and integrates Ethernet TCP/IP RJ45 for network connectivity plus a serial link 2 female mini DIN RS485 at 19.2 kbit/s. The module format is standard, and it supports 2 racks (12 slots) or 4 racks (4/6/8 slots).
Industry Applications
Machine Control
In packaging or material handling lines, the TSXP57203M manages discrete I/O for sensors, actuators, and motor starters. Its 0.3 ms fast task overhead enables rapid fault detection and response, reducing machine downtime.
Process Monitoring
With 24 analog I/O capacity, this PLC handles temperature, pressure, or flow signals. The Ethernet TCP/IP interface allows seamless data exchange with SCADA or HMI systems, supporting real-time monitoring and data logging.
Retrofit and Upgrade Projects
Replacing older TSX Micro processors with the TSXP57203M brings modern networking capabilities without changing the entire system architecture. The RS485 serial link integrates with legacy field devices, while Ethernet TCP/IP connects to modern control networks.
Installation and Setup Guidance
Mount the TSXP57203M in a standard TSX Micro rack, ensuring proper grounding and ventilation. Connect the Ethernet cable to the RJ45 port for network communication. For serial devices, use a female mini DIN connector wired for RS485 at 19.2 kbit/s. Configure the processor using PL7 Junior/Pro software. Verify that the PCMCIA card (if used) is properly inserted before powering up. The CE marking indicates compliance with applicable European directives.
Maintenance and Reliability
Regularly inspect the processor for dust accumulation and ensure ambient temperature stays between 32…140 °F (0…60 °C). The IP20 protection rating requires installation in a clean, dry enclosure. Check LED indicators: green RUN for processor running, red I/O for module or configuration fault, red ERR for processor or system fault, and yellow TER for terminal port activity. Follow manufacturer guidelines for periodic testing.
Compatibility and Integration
The TSXP57203M integrates with Schneider Electric TSX Micro I/O modules, racks, and power supplies. It supports up to 2 communication modules for additional fieldbus or network interfaces. The Ethernet TCP/IP port enables connection to Modbus TCP/IP networks, while the RS485 serial link communicates with Modbus RTU or ASCII devices. The processor works with PL7 Junior/Pro software for programming and configuration.
