Schneider Electric TSXP573623AM Double-Format PL7 Processor Module

Description

The Schneider Electric TSX P573623AM is a double-format PL7 processor module designed for demanding Modicon Premium automation systems. It delivers stable execution performance for large PLC programs while maintaining reliable communications across Ethernet and serial networks. The CPU integrates Transparent Ready Ethernet, which enables seamless data exchange with SCADA systems and plant-wide networks. Moreover, its 64 Kwords of internal RAM and PCMCIA expansion options support complex control strategies used in modern manufacturing environments. This module remained popular in energy, process, and general industrial applications until its discontinuation, with service support available through December 31, 2026.

Functional Highlights

The module offers strong multi-task processing capabilities that help engineers manage time-critical logic. In addition, its support for up to sixteen racks allows flexible system expansion without redesigning the automation architecture. The onboard Ethernet TCP/IP interface simplifies diagnostics, therefore reducing downtime during commissioning or maintenance. Its PL7 Junior/Pro compatibility ensures stable program migration for facilities operating legacy Modicon Premium systems. For instance, plants with continuous-process loops benefit from its capacity to execute up to forty-five simple control loops.
