TSXP574634M Modicon Premium 2048kB Program RAM

Product Overview

The Schneider Electric TSXP574634M (Telemecanique) is a high-performance, double-format **Unity Processor Module** engineered for the flagship Modicon Premium Automation Platform. Built to handle complex, large-scale industrial process control and high-density discrete operations, this processor seamlessly integrates with **Unity Pro** programming software. It supports robust system architecture scaling up to 16 racks (128 total slots), managing up to 2040 Discrete I/O points and 256 Analog I/O points. Equipped with integrated Ethernet TCP/IP, USB, and RS485 serial interfaces, the TSXP574634M offers exceptional throughput with Boolean execution speeds down to 0.039 µs.

Core Technical Advantages

Built-in Multi-Protocol Communication Suite

The TSXP574634M eliminates the need for standalone communication co-processors in many applications. It features an integrated 10BASE-T/100BASE-TX Ethernet TCP/IP RJ45 port for Transparent Ready networking, a 12 Mbit/s USB commissioning port for high-speed programming, and a non-isolated RS485 female mini-DIN serial connection for legacy fieldbus integration.

Scalable High-Speed Performance Engine

Designed for demanding multi-tasking environments, the CPU handles 1 master task, 1 fast task (0.08 ms overhead), and up to 64 event-driven tasks. With processing speeds reaching 15.75 Kinst/ms for 100% Boolean logic, it delivers sub-microsecond response times required for high-speed packaging, automotive assembly, and continuous process loops.

Flexible Memory Architecture via PCMCIA

Out of the box, the internal RAM provides 440 kB shared for program and data. When expanded with an optional PCMCIA memory card, the architecture expands to 2048 kB for program execution, 440 kB for dedicated data storage, and supports up to 16 MB of additional file archives for historical data logging and recipe storage.

Technical Specifications

Installation and Maintenance

Rack Installation: Power off the system before mounting. Insert the double-format module into its dedicated slots on the Modicon Premium rack base and tighten the top and bottom screws securely.

Wiring & LED Status: Plug the RJ45 Ethernet, USB, or RS485 cables into their front ports. Use the LED status indicators (RUN, ERR, I/O) to monitor operational health and network activity.

Engineering Advantages

High Rack Scalability for Massive Distributed I/O

Supporting configurations up to 8 racks with 12 slots each or 16 racks with 4/6/8 slots, the TSXP574634M offers flexible expansion for plant-wide control architectures without sacrificing processing speed or communication response times.

Advanced Function Block Capabilities

With support for unlimited DFB (Derived Function Blocks) and EFB (Elementary Function Blocks), engineers can write modular, reusable code inside Unity Pro, significantly reducing control system engineering time and software maintenance overhead.

Industrial Standards & Harsh Environment Ratings

Engineered for tough industrial environments, the module features TC protective treatment, IP20 degree of protection, UL 508 and CSA Class I Div 2 certifications, along with marine classification approvals including DNV, GL, ABS, and LR.
