6ES7318-3EL01-0AB0 Siemens Simatic S7-300 CPU 319-3 PN/DP Central Processing Unit

Product parameters

CPU model: S7-300 CPU 319-3 PN/DP (Note: 6ES7318-3EL01-0AB0 is the order number for this model), integrated with dual communication interfaces of Profinet and Profibus-DP.

Processing performance: The instruction processing speed is extremely fast, with bit operations approximately 0.01μs, word operations approximately 0.02μs, and double-word operations approximately 0.03μs. It supports ultra-large-scale program operations (with a maximum program capacity of up to 20MB).

Memory configuration: The working memory is 10MB (for programs) + 20MB (for data). Storage can be expanded via a Micro SD card (up to 32GB), supporting massive data log and program backup.

I/O expansion capability: No built-in I/O, up to 64 S7-300 modules (including digital quantity, analog quantity, special function modules, etc.) can be expanded, meeting large-scale control requirements.

Communication interface One Profinet Ethernet port (with a 2-port switch, supporting TCP/IP and PROFINET IO), one Profibus-DP interface (master/slave mode, maximum transmission rate 12Mbps), and one MPI interface (for programming devices to connect with HMI).

Power supply requirement: It needs to be matched with the S7-300 power module (such as PS307), and the working voltage supports DC 24V or AC 120/230V (depending on the power module).

Environmental adaptability: Operating temperature 0°C - 60°C, storage temperature -40 °C - 70°C, protection grade IP20 (needs to be installed in a control cabinet).

Function

Ultra-high performance control: Supports multiple programming methods such as ladder diagram (LAD), Function Block diagram (FBD), and Structured Control Language (SCL), capable of handling complex logic control, multi-variable process regulation (such as PID multi-loop control), and high-speed computing tasks.

Strong communication capability: High-speed data interaction with industrial Ethernet devices (such as robots, intelligent sensors, and SCADA systems) is achieved through Profinet, and distributed I/O (such as ET200 series) is connected through Profibus-DP to meet the networking requirements of large-scale equipment.

Massive data management: With large-capacity memory and SD card expansion, it can store long-term production data logs and process parameter records, support data traceability and analysis, and be adapted to the data-driven management of intelligent factories.

Advanced Diagnosis and Security: Equipped with comprehensive self-diagnosis function, it can monitor the module hardware, communication link and program running status in real time. Fault information is intuitively displayed through LED indicator lights or TIA Portal. Support program encryption, copy protection and communication permission management to ensure system security.

Compatible with complex functional modules: expandable positioning modules, high-speed counting modules, redundant modules, etc., supporting special scenarios such as high-precision motion control (such as multi-axis synchronization) and redundant system construction (to enhance reliability).

Application scenarios

Large-scale production line automation: such as vehicle manufacturing assembly lines and semiconductor wafer production lines, controlling the coordinated operation of dozens of devices (welding robots, conveying systems, inspection instruments, etc.) to ensure high-rhythm and high-precision production.

Complex process industrial control: In large-scale chemical, metallurgical and energy plants, hundreds of process variables (temperature, pressure, flow rate, liquid level, etc.) are monitored and regulated to achieve multi-section linkage control and process optimization.

Core control of high-end equipment: Integrated into large CNC machine tools and aerospace testing equipment, it undertakes high-precision motion control and data acquisition tasks, meeting the requirements of high reliability and high response speed.

Distributed intelligent factory: As the core controller at the workshop level, it connects with the factory MES/ERP system through industrial Ethernet to achieve real-time upload and remote monitoring of production data, supporting intelligent manufacturing decision-making.
