Schneider TSXP57303AMC Modicon Premium Double-Format PL7 Processor

Product Overview

The TSXP57303AMC is a high-performance, double-format processor belonging to the Modicon Premium automation platform. Designed for mid-to-high complexity industrial applications, this processor utilizes PL7 Junior/Pro software to manage sophisticated control logic. With a robust discrete I/O capacity of up to 1024 points and specialized support for up to 45 process control loops, the TSXP57303AMC is a staple in sectors like water treatment, food and beverage, and infrastructure management. This "double-format" module occupies two slots on the Premium rack, providing the necessary hardware overhead for high-speed Boolean execution (0.12 µs) and extensive network connectivity, including support for CANopen, AS-Interface, and multiple fieldbus modules.

Technical Configuration

The TSXP57303AMC is engineered for versatility and rapid processing in distributed architectures:

• Memory Management: Features 64 Kwords of internal RAM for program and data. Memory is expandable via PCMCIA cards, supporting up to 384 Kwords for programs and 2688 Kwords for additional data storage.

• Multitasking Capability: Supports an advanced application structure consisting of one master task, one fast task, and 64 event-triggered tasks for prioritized response to critical field signals.

• Integrated Communication: Includes a non-isolated serial link (Mini-DIN) supporting speeds up to 115 kbit/s. It can manage up to 3 network modules and 2 fieldbus modules simultaneously.

• Performance: Delivers high-speed instruction execution, reaching up to 6.57 Kinst/ms for 100% Boolean logic without an external PCMCIA card.

• Diagnostic LEDs: Equipped with local signaling for system status: RUN (Green), I/O fault (Red), ERR system fault (Red), and TER terminal port activity (Yellow).

Technical Specifications

Technical FAQs

Does the TSXP57303AMC require a battery for memory retention?The processor uses internal RAM which requires a backup battery (typically located in the rack power supply or on the processor itself) to retain the program and data object areas (%MW) during power outages. For permanent storage, a PCMCIA Flash memory card is recommended.

Can I use Unity Pro / EcoStruxure Control Expert with this processor?The TSXP57303AMC is specifically designed for the PL7 software environment. While some Modicon Premium processors can be upgraded to Unity Pro, this specific AMC variant is optimized for legacy PL7 Junior and Pro applications.

What is the maximum number of racks this processor can manage?It can support up to 16 racks if using 4, 6, or 8-slot configurations, or up to 8 racks when using 12-slot racks, allowing for a total of 128 slots across the architecture.

Engineering & Installation Guide

• Slot Placement: As a double-format module, the TSXP57303AMC must be placed in the first two slots of the TSXRKY rack (Slots 0 and 1). Ensure the rack power supply (TSXPSY) is rated to handle the 1000 mA draw of the processor plus all associated I/O modules.

• Thermal Management: To maintain the 0 to 60 deg C operating range, ensure a minimum clearance of 100 mm above and below the rack. The processor is treated with Humiseal 1A33 conformal coating, providing enhanced resistance to humidity and chemical contaminants (Pollution Degree 2).

• PCMCIA Card Handling: Only insert or remove PCMCIA memory or communication cards when the processor is powered down or in a "STOP" state to avoid data corruption. Ensure the locking latch is fully engaged to prevent vibration-induced disconnects.

• Grounding: Ensure the TSXRKY rack is bonded to a low-impedance functional earth. The processor's shielding and noise immunity depend heavily on the integrity of the rack's grounding strip.
