Siemens 6ES7456-4EY00-0AE0 FM 456-4 Application Module

Product Overview

This application module provides high-speed signal processing for the SIMATIC M7-400 automation system. It integrates a powerful AT-compatible processor with 2 MB of built-in DRAM. The module measures 50 mm in width, 290 mm in height, and 210 mm in depth. Its robust design weighs approximately 1,200 grams for secure rack mounting. You can insert this module into any free slot of the M7-400 rack. The device includes both a VGA interface and a standard keyboard connector.

The processor operates at a clock frequency of 66 MHz for demanding calculation tasks. It features an integrated math coprocessor for floating-point arithmetic operations. The module provides 512 KB of flash EPROM for storing the firmware permanently. You can expand the memory using two additional SIMM sockets on the board. The module supports both MS-DOS and Windows NT operating systems natively.

Key Features and Benefits

This module executes complex mathematical algorithms independently from the main CPU. Its built-in VGA port simplifies operator interaction for monitoring and diagnostics. You can run third-party applications directly on the module for specialized tasks. The processor delivers deterministic performance for time-critical control functions. You can also store application-specific parameters in the flash memory permanently.

Installation and Configuration

You slide the module into any available slot of the M7-400 rack system. The backplane bus provides power and communication with the main CPU automatically. You then connect a standard VGA monitor and PS/2 keyboard for local operation. The module boots its operating system from the onboard flash memory. For custom applications, you can load software through the floppy disk drive. The module also communicates with the main CPU through the backplane bus.

Typical Applications

Aerospace testing facilities use this module for high-speed data acquisition tasks. Research laboratories rely on it for running complex simulation models. The module also serves in specialized machine control requiring mathematical computations.
