The 6ES7314-6EH04-0AB0 is a compact CPU module from Siemens’ SIMATIC S7-300 series, specifically the CPU 314C-2 PtP model. It is designed for medium-sized industrial automation applications that require integrated I/O, reliable processing, and dedicated point-to-point (PtP) communication capabilities for connecting to serial devices.
Key Features:
-
Core Processing:
- Equipped with a 32-bit processor optimized for real-time control, delivering fast instruction execution (as low as 0.1 µs for basic operations) to handle complex automation tasks efficiently.
- Includes 256 KB of work memory (RAM) for program execution and data handling, with support for external load memory via SIMATIC Micro Memory Cards (MMC, up to 8 MB) for secure storage of programs, configurations, and user data.
-
Integrated I/O:
- Combines digital and analog I/O to minimize the need for external modules:
- 24 digital inputs (24 V DC) and 16 digital outputs (24 V DC, 0.5 A per channel) for direct connection to sensors, actuators, and discrete devices.
- 4 analog inputs (13-bit resolution, supporting 0–10 V DC or 4–20 mA) and 2 analog outputs (13-bit resolution, 0–10 V DC or 4–20 mA) for interfacing with analog sensors (e.g., temperature, pressure) and actuators (e.g., variable speed drives, valves).
- Combines digital and analog I/O to minimize the need for external modules:
-
Communication Interfaces:
- Point-to-Point (PtP) interface (RS485/RS232, configurable via software) for serial communication with devices such as barcode scanners, printers, modems, or legacy controllers. It supports standard protocols including ASCII, 3964R, and Modbus RTU (master/slave), enabling seamless data exchange with serial-based equipment.
- MPI interface (187.5 kbps) for programming, HMI communication, and data exchange with other S7-300/400 CPUs, simplifying network setup and diagnostics.
-
Functional Capabilities:
- Complies with IEC 61131-3 programming standards, supporting languages like LAD, FBD, STL, and SCL for modular, reusable code development.
- Integrated diagnostic features with status LEDs (RUN, STOP, ERROR, PtP) for quick visual monitoring of operational status, communication health, and I/O faults.
- Configurable and programmable via Siemens’ TIA Portal (STEP 7) software, streamlining setup, commissioning, and maintenance workflows.
-
Mechanical & Environmental Design:
- Compact, DIN rail-mountable housing designed for integration into S7-300 rack systems, optimizing space in control cabinets.
- Built for industrial durability, operating reliably in a temperature range of -25°C to +60°C and adhering to standards such as CE, UL, and IEC 61131-2 for resistance to vibration, shock, and electromagnetic interference (EMC).
Applications:
Ideal for medium-scale automation tasks in industries such as manufacturing, logistics, or process control, where integrated analog/digital I/O and serial communication (PtP) are critical. It excels in scenarios requiring direct control of mixed discrete/analog devices alongside connectivity to serial equipment (e.g., barcode readers, legacy controllers) via standard protocols like Modbus RTU.
This CPU balances integrated I/O versatility, dedicated PtP communication, and robust processing, making it a flexible solution for applications needing seamless integration with serial devices while managing core automation logic.
