Schneider TSXP57103M Micro PLC: Non-Isolated Serial Link, 19.2 kbit/s

Product Overview

Part of the TSX Micro PLCs family, this processor integrates an internal RAM of 32 Kwords for data processing, ensuring fast handling of control logic. Its non-isolated serial link with two female mini DIN connectors operates at 19.2 kbit/s, providing straightforward connectivity for programming and monitoring.

Technical Specifications Breakdown

• Internal RAM: 32 Kwords dedicated to data, expandable with a PCMCIA card for an additional 128 Kwords data storage and 64 Kwords program memory.
• Inrush Current: Handles 38 A at both 240 V and 100 V, ensuring robust startup under varying line conditions.
• I/O Capacity: Supports up to 512 discrete I/O and 24 analogue I/O, suitable for mixed-signal applications.
• Execution Speed: Boolean instructions execute in 0.5 µs without PCMCIA card, or 0.6 µs with card, enabling responsive control loops.
• Communication Module Capacity: Accommodates 1 network module, 2 AS-Interface bus modules, and 1 CANopen, offering flexible networking.

Industry Applications

In manufacturing lines, the TSXP57103M is used for controlling conveyor systems and packaging machines, where its 512 discrete I/O handle numerous sensors and actuators. For process control, the 24 analogue I/O manage temperature or pressure transducers, while the CANopen interface coordinates drives and remote I/O. Its compact standard module format fits easily into existing cabinets, reducing installation time.

Installation & Setup Guidance

Mount the TSXP57103M in a standard rack system: up to two racks with 12 slots each, or four racks with 4, 6, or 8 slots. Connect the serial link via the two female mini DIN ports using a shielded cable for reliable communication at 19.2 kbit/s. Ensure the 5 V DC supply can deliver 440 mA. The IP20 enclosure suits clean indoor environments; maintain ambient temperature between 32…140 °F (0…60 °C).

Maintenance & Reliability

From a maintenance engineer's perspective, the TSXP57103M offers straightforward diagnostics via four front-panel LEDs: green RUN, red I/O fault, red ERR, and yellow TER activity. These indicators allow quick status checks without a programming terminal. The module consumes only 440 mA at 5 V DC, minimizing heat buildup. Periodic inspection of connectors and ambient conditions ensures long-term reliability.

Compatibility & Integration

It supports one network module, two AS-Interface bus modules, and one CANopen, enabling connection to drives, sensors, and remote I/O. The non-isolated serial link uses PL7 Junior/Pro software for programming. Memory expansion via PCMCIA card (128 Kwords data, 64 Kwords program) allows for larger applications.

Selection Guide & Purchasing Advice

Before ordering, verify your rack configuration and I/O requirements. The TSXP57103M fits 2-rack (12 slots) or 4-rack (4/6/8 slots) setups. Ensure your power supply can deliver 440 mA at 5 V DC. For extended memory, order a compatible PCMCIA card separately. AutoDCSTech stocks this module and can confirm current lifecycle status and availability.

Troubleshooting & Common Issues

If the ERR LED lights red, check for processor or system faults. An I/O LED indicates module or configuration errors—verify wiring and module seating. The TER LED should flash during terminal activity; if not, check the serial cable and PL7 software connection. For slow execution, consider using the PCMCIA card to optimize program memory. Always follow the manufacturer's guidelines for diagnostics.
