When a Legacy Line Stalls, the TSXP572623M Keeps It Running
A plant engineer faces a familiar problem: a packaging line runs on a discontinued processor, spare units sit in short supply, and downtime costs climb every hour. The Schneider Electric TSXP572623M answers that challenge. As a double-format PL7 processor in the Modicon Premium automation platform, it handles up to 30 simple process control loops while keeping existing TSX Micro PLC installations productive.
This processor fits plants that need proven control capacity without a full platform migration. It supports 1024 discrete I/O points and 80 analogue I/O points, so it covers mixed signal environments. The integrated Ethernet TCP/IP port (RJ45, 10/100 Mbit/s) and non-isolated serial link (2 female mini DIN, 19.2 kbit/s) let engineers connect to supervisory systems and programming terminals without extra hardware.
Key Parameters That Drive Real Throughput
Processing Speed
Boolean execution takes 0.19 µs per instruction without a PCMCIA card and 0.21 µs with one installed. The processor reaches 4.76 Kinst/ms for 100% Boolean logic without a PCMCIA card. That speed keeps scan times predictable on fast production lines.
Memory Architecture
Internal RAM provides 48 Kwords for program and data. With a PCMCIA card, memory expands to 160 Kwords for program storage and 2688 Kwords for additional data. Plants that log process data benefit from this headroom.
Scalable Rack Support
The processor supports up to 16 racks across 4, 6, 8, and 12-slot configurations. This scalability lets engineers expand I/O as production demands grow.
Task Structure
The application structure includes 1 master task, 1 fast task, and 64 event tasks. System overhead runs at 1 ms for the master task and 0.35 ms for the fast task. Event-driven logic responds quickly to machine signals.
Where This Processor Earns Its Place
Process Control Loops
Water treatment and chemical dosing skids rely on simple control loops. The TSXP572623M manages 10 up to 30 simple loops, covering flow, level, and temperature regulation in one processor.
Mixed I/O Manufacturing Cells
A machining cell with 1024 discrete points and 80 analogue points fits this processor’s capacity. Engineers avoid splitting control across multiple CPUs.
Networked Factory Floors
Ethernet TCP/IP connectivity supports plant-level data collection. The communication module capacity includes 1 fieldbus module, 4 AS-Interface bus modules, and 1 CANopen connection.
Replacing an Aging Processor Without Rebuilding the Line
Angle D applies here: this processor serves as a drop-in upgrade path for legacy TSX Micro PLC installations. Engineers verify rack compatibility, confirm I/O counts, and transfer existing PL7 Junior/Pro programs. The RESET button initiates a cold start when needed, simplifying commissioning after a swap.
Two PCMCIA slots accept one memory extension card and one communication card or a 4 MB SRAM memory extension card. That flexibility lets a single spare unit serve multiple configurations across a plant.
Installation Notes for Field Engineers
Mount the processor in a compatible rack and confirm the 1110 mA at 5 V DC current draw against the power supply budget. The module format is double-width, so plan panel space accordingly. The unit weighs 1.68 lb (0.76 kg).
Operating temperature ranges from 32 to 140 °F (0 to 60 °C). Storage ranges from -13 to 158 °F (-25 to 70 °C). Relative humidity runs 10 to 95% without condensation during operation. The IP20 rating suits cabinet-mounted installations, and the TC protective treatment adds resistance in industrial air.
Reliability and Maintenance Planning
Front-panel LEDs give fast diagnostics: green RUN indicators for the processor and Ethernet port, red LEDs for faults and collisions, and yellow LEDs for terminal, link, and transmission activity. Technicians read status without opening cabinets.
Inspect connections and ventilation periodically. Follow the manufacturer’s safety manual for all service work. Keep spare PCMCIA cards on hand, since memory and communication options affect program capacity.
Compatibility and Integration
The processor works within the Modicon Premium automation platform and uses PL7 Junior/Pro software. It carries CE marking and meets standards including IEC 61131-2, UL 508, and CSA C22.2 No 142. Marine certifications include BV, DNV, RMRS, ABS, GL, LR, and RINA.
What to Confirm Before You Buy
Check rack count, I/O requirements, and PCMCIA needs against your application. Confirm whether CANopen is used, since fieldbus module capacity changes in that case. Verify current lifecycle status and availability with SpareTechPLC before ordering, as returnability is not offered on this item.
