The 6ES7313-5BG04-0AB0 is a compact CPU module from Siemens’ SIMATIC S7-300 series, specifically the CPU 313C-2 DP model, designed for mid-sized industrial automation tasks with integrated I/O and communication capabilities.
Key Features:
-
Core Processing:
- Equipped with a 32-bit processor optimized for fast execution of automation tasks, with typical instruction execution times as low as 0.1 µs for basic operations, ensuring responsive control.
- Includes 64 KB of work memory (RAM) for program execution and data handling, plus support for external load memory via SIMATIC Micro Memory Cards (MMC, up to 8 MB) for program storage.
-
Integrated I/O:
- Features 16 digital inputs (24 V DC) and 16 digital outputs (24 V DC, 0.5 A per channel), eliminating the need for separate I/O modules in small to mid-sized setups. This integration reduces wiring and saves cabinet space.
-
Communication Interfaces:
- PROFIBUS DP interface (up to 12 Mbps) for connecting to distributed I/O, drives, or other field devices, supporting both master and slave modes for flexible network integration.
- MPI interface (187.5 kbps) for programming, HMI communication, and data exchange with other S7-300/400 CPUs, enabling easy configuration via STEP 7 software.
-
Functional Capabilities:
- Supports standard automation functions such as timers, counters, and arithmetic operations, as well as more advanced features like data blocks, function blocks, and structured programming.
- Includes diagnostic functions for I/O and communication, with status LEDs (e.g., RUN, ERROR, DP) for quick troubleshooting.
- Compatible with Siemens’ TIA Portal (STEP 7) for programming and configuration, streamlining setup and maintenance.
-
Mechanical & Environmental Design:
- Compact, DIN rail-mountable housing, fitting seamlessly into S7-300 rack systems for space-efficient installation in control cabinets.
- Operates in a wide temperature range (-25°C to +60°C) and withstands industrial-grade vibration and shock, complying with standards like CE, UL, and IEC 61131-2 for reliability in harsh environments.
Applications:
Ideal for controlling mid-sized machines or production lines in industries such as manufacturing, packaging, or material handling. Its integrated I/O and PROFIBUS DP connectivity make it suitable for applications requiring direct control of sensors/actuators alongside communication with distributed devices, balancing performance and cost-effectiveness for modular automation setups.
This CPU is valued for its all-in-one design (processing + I/O + communication), robust industrial performance, and ease of integration, making it a versatile choice for mid-range automation tasks.
