The Siemens 6ES7314-6BH04-0AB0 is a specialized compact CPU within the SIMATIC S7-300 controller family. This module combines standard processing power with integrated input and output channels. It serves as a space-saving solution for machine control requiring localized I/O. The CPU 314C-2 PtP features a built-in serial interface for point-to-point communication.
Integrated Hardware Specifications
- Work Memory: 192 KB integrated memory for user programs.
- Digital I/O: 24 digital inputs and 16 digital outputs (24V DC).
- Analog I/O: 5 analog inputs (4 voltage/current, 1 Pt100) and 2 analog outputs.
- High-Speed Functions: 4 integrated counters reaching frequencies up to 60 kHz.
- Interfaces: One MPI port and one RS422/485 serial interface.
- Physical Requirements: Requires a SIMATIC Micro Memory Card (MMC) for operation.
- Connection: Uses two 40-pin front connectors for wiring.
Operational Capabilities
This controller executes bit instructions in approximately 0.06 microseconds. The integrated PtP interface supports ASCII and 3964(R) protocols for simple data exchange. Engineers often use this model for positioning tasks or frequency measurement. The compact design reduces the overall footprint in the control cabinet. It integrates seamlessly with STEP 7 programming environments for rapid deployment.
Application and Lifecycle Status
The S7-300 314C-2 PtP fits well in wood processing and packaging machinery. It handles automated assembly lines and specialized tool manufacturing effectively. Siemens moved this specific part number into the phase-out period in late 2023. This status indicates the product remains available primarily for spare parts and system maintenance. Facilities should consider migrating to S7-1500 controllers for new installations.
