Description

The Siemens 6FM1470-4BA20, also known as the WF 470, is a specialized intelligent processing module engineered for the Simatic S5 automation system. This coprocessor is designed to offload intensive visual display generation and operator interface management from the primary S5 CPU. By handling pixel-oriented graphics, alarm logging, and real-time process visualization, the module ensures that critical control tasks remain unaffected by the overhead of complex display requirements. It is widely utilized in industrial environments such as automotive assembly, chemical processing, and metal rolling mills where high-performance graphical feedback is essential for operator efficiency.

Features

• Dedicated 16-bit onboard microprocessor for asynchronous graphics routine execution.
• High-speed multi-port RAM for efficient data exchange between the S5 CPU and the module.
• Integrated bus decoupling to protect internal circuitry from electrical noise and ground potential shifts.
• Optimized for pixel-oriented display outputs and real-time alarm management.
• Standard single-width S5 rack-mount form factor for seamless integration into existing backplanes.
• Front-panel diagnostic LEDs for rapid status monitoring and troubleshooting.

Technical Specifications

Installation Guidelines

• Ensure the Simatic S5 rack power is fully disconnected before inserting or removing the module to prevent damage to the backplane pins.
• Verify that the module is correctly seated in the intended slot to ensure proper alignment with the parallel bus connectors.
• Maintain adequate clearance around the module to allow for natural convection cooling; do not obstruct airflow in the rack.
• Use shielded cables for video signal transmission to minimize EMI interference in high-noise industrial environments.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to protect sensitive internal components.

FAQ

What is the primary function of the 6FM1470-4BA20?

The module acts as a coprocessor to handle graphical display tasks, which reduces the computational load on the main Simatic S5 CPU and prevents screen refresh latency.

Is this module compatible with all S5 systems?

The 6FM1470-4BA20 is designed for the Simatic S5 series. Please verify your specific CPU and rack configuration to ensure compatibility with the WF 470 intelligent module series.

How is the module powered?

The module draws its operating power directly from the Simatic S5 backplane bus, with a typical consumption of 8.5 W.
