6ES7317-6FF04-0AB0 SIEMENS

6ES7317-6FF04-0AB0 SIEMENS Basis unit

Product  Description：

The Siemens 6ES7317-6FF04-0AB0 is a high-performance Fail-safe Central Processing Unit (CPU) belonging to the SIMATIC S7-300 series. It is specifically engineered for plants with high requirements for processing speed and functional safety. This module integrates both standard control functions and safety-related tasks into a single unit, compliant with safety standards up to SIL 3 (IEC 61508) and PLe (ISO 13849-1).

Product Specifications

• Product Type: CPU 317F-2 DP

• Hardware Version: 01

• Firmware Version: V3.2

• Work Memory: 1.5 MB total (integrated), without battery backup.

• Load Memory: Expandable via Micro Memory Card (MMC) up to 8 MB.

• Processing Times: $0.025 \text{ \mu s}$ for bit operations, $0.03 \text{ \mu s}$ for word operations, $0.04 \text{ \mu s}$ for fixed-point arithmetic, and $0.16 \text{ \mu s}$ for floating-point arithmetic.

• First Interface: Integrated MPI/DP interface (RS 485) supporting up to 12 Mbit/s.

• Second Interface: Integrated PROFIBUS DP interface (RS 485) for distributed I/O.

• I/O Address Area: 8192 bytes for input and 8192 bytes for output.

• Dimensions: 80 mm width, 125 mm height, 130 mm depth.

• Net Weight: Approximately 460 g.

Product Advantages

• Integrated Safety: By combining standard and safety-related programs on one CPU, users save on hardware costs, reduce cabinet space, and simplify engineering workflows.

• High-Speed Processing: The CPU 317F-2 DP offers significant command execution speeds, making it ideal for complex control tasks and high-speed manufacturing processes.

• Extensive Memory: With 1.5 MB of work memory, it can handle large user programs and extensive data structures without performance degradation.

• Distributed Intelligence: The dual PROFIBUS interfaces allow for flexible networking, enabling the CPU to act as a master or slave in large-scale distributed I/O architectures.

• Diagnostic Capabilities: Integrated system diagnostics allow for rapid fault localization, reducing downtime and improving overall system availability.

Important Considerations and Precautions

• Micro Memory Card (MMC): An MMC is strictly required for operation as the CPU does not have internal non-volatile load memory.

• Safety Engineering: Programming safety functions requires the S7 Distributed Safety or SIMATIC Safety Integrated software package. Only authorized personnel should handle safety configurations.

• Power Supply: Ensure a stable $24 \text{ VDC}$ power supply. Significant voltage fluctuations can cause the CPU to enter a STOP state or lead to hardware damage.

• Environmental Limits: The module is designed for an ambient operating temperature range of $0 \text{°C}$ to $60 \text{°C}$. Proper ventilation in the control cabinet is necessary to prevent overheating.

• Electrostatic Discharge (ESD): When handling the module or inserting the MMC, follow ESD protection protocols to prevent invisible damage to internal electronic components.

• Legacy Status: While highly reliable, the S7-300 series is a mature platform. For new greenfield projects, users should consider the S7-1500 series for longer lifecycle support.

Product Applications

The 6ES7317-6FF04-0AB0 is primarily used in complex industrial environments where human safety and high-speed automation intersect.

• Automotive Manufacturing: Managing robotic assembly lines and press shops where safety light curtains and emergency stop circuits must be integrated with high-speed motion control.

• Material Handling and Logistics: Controlling large-scale conveyor systems, automated warehouses, and elevators that require fail-safe speed monitoring and positioning.

• Machine Tools: Operating high-precision CNC or specialized machinery that requires simultaneous safety monitoring and complex mathematical calculations.

• Packaging Industry: Managing high-speed wrapping and bottling lines that necessitate quick response times for both production efficiency and operator protection.

• Process Automation: Used in sectors like chemical or food and beverage for specific sub-processes that require functional safety certification for valves and pumps.
