The Siemens 6ES7416-3ES06-0AB0 is a high-performance SIMATIC S7-400 CPU (Central Processing Unit), designed for demanding industrial automation applications requiring large program capacity, fast processing speeds, and flexible communication capabilities. It belongs to the S7-400 standard CPU family, not the redundant H-series, making it suitable for non-redundant but high-performance control tasks.
- Product Series: SIMATIC S7-400 (Standard CPU, non-redundant)
- CPU Model: CPU 416-3ES
- Hardware Version: V6.0
- Product Status: Discontinued (no longer in production; Siemens recommends migrating to the SIMATIC S7-1500 series for new projects)
- Key Function: Serves as the core processing unit for medium to large-scale automation systems, handling complex logic, data processing, and multi-protocol communication.
- Dimensions (W×H×D): ~233 mm × 303 mm × 65 mm (standard S7-400 rack-mount form factor, compatible with UR2/UR2-H racks)
- Weight: Approximately 1.2 kg
- Operating Temperature: -20°C to +60°C (non-condensing)
- Storage Temperature: -40°C to +85°C
- Protection Rating: IP20 (intended for indoor, control cabinet mounting; not suitable for direct field installation)
- Mounting: Installed in S7-400 racks via the backplane bus connector; secured with locking clips to prevent accidental disconnection during operation.
The CPU 416-3ES is engineered for medium to large-scale industrial control systems that demand high processing efficiency and flexible connectivity. Its core roles include:
- High-Speed Processing:
- Handles large user programs (up to 6 MB code memory) and high-volume process data (6 MB data memory), suitable for complex production lines or process control systems.
- Reduces cycle times for time-critical tasks, such as real-time monitoring and fast response to sensor signals.
- Multi-Network Integration:
- Manages two independent PROFIBUS DP networks simultaneously, enabling distributed I/O expansion (e.g., with ET 200M modules) and connection to field devices like drives and valves.
- Communicates with HMIs, SCADA systems, and programming devices via the MPI interface for operator control and system configuration.
- Diagnostics & Reliability:
- Built-in LED indicators for power, CPU status, and communication errors, enabling quick on-site troubleshooting.
- Supports Configuration in Run (CiR) (with compatible modules), allowing hardware/software modifications without stopping the entire system—reducing maintenance downtime.
Typical Applications:
- Automotive manufacturing (e.g., body-in-white assembly, paint shop control)
- Food and beverage processing (large-scale production lines with multiple control loops)
- Material handling systems (e.g., automated warehouses, conveyor networks)
- Chemical and petrochemical plants (non-redundant process units)
- Renewable energy systems (e.g., solar farm inverter control, wind turbine park management)
As the S7-400 series is discontinued, Siemens recommends migrating to the SIMATIC S7-1500 series for new installations or system upgrades. Key advantages of the S7-1500 over the S7-400 include:
- Significantly higher processing power (e.g., CPU 1516-3 PN/DP processes 1k binary instructions in ~0.001 ms).
- Native PROFINET IO support (in addition to PROFIBUS) with faster communication speeds (up to 1 Gbit/s).
- Seamless integration with TIA Portal engineering software (replacing the older STEP 7), enabling unified configuration, programming, and diagnostics.
- Compact design, lower power consumption, and enhanced cybersecurity features.
Recommended Replacement Model:
S7-1500 CPU, e.g.,
6ES7516-3AN01-0AB0 (CPU 1516-3 PN/DP), which offers comparable memory capacity (10 MB program / 10 MB data) and superior performance for modern automation needs.
