Product Overview

The VIPA 317-2AJ12​ CPU317SE is a high-performance central processing unit (CPU) belonging to the VIPA SPEED7 family of programmable logic controllers, renowned for their exceptional processing speed and full hardware compatibility with the Siemens SIMATIC S7-300 system. This powerful CPU is engineered to handle medium to large-scale automation tasks that demand fast cycle times, complex data processing, and extensive network connectivity. The core of its performance lies in VIPA’s proprietary SPEED7 technology, which utilizes a high-frequency ASIC (Application-Specific Integrated Circuit) to execute user programs with remarkable efficiency, often outperforming standard PLCs in its class. The VIPA 317-2AJ12​ serves as the central brain of a control system, executing logic, managing I/O, and communicating with other devices across a network. It is specifically designed for engineers seeking the reliability and familiarity of the S7-300 platform but with enhanced performance and flexible configuration options.As a slot-PLC, the CPU317SE 317-2AJ12​ is mounted directly onto a VIPA 300S backplane, which provides the electrical bus for connecting a wide array of digital, analog, and special function modules. This modularity allows for the creation of a tailored control system precisely scaled to the application’s requirements. A key feature of this CPU is its integrated communication capability, typically featuring both a Multi-Point Interface (MPI) for programming and peer-to-peer communication and a PROFIBUS-DP interface that can be configured as a master or slave, enabling seamless integration into distributed I/O networks. The VIPA 317-2AJ12​ is programmed using industry-standard software compatible with STEP 7, allowing for easy migration of projects and leveraging of a vast library of existing code. Its robust design, ample user memory, and fast processing make it an ideal controller for complex applications in machine building, process automation, and manufacturing lines where precision, speed, and network integration are critical.

Main Features and Advantages

Unmatched processing power with SPEED7 technology: The defining characteristic of the VIPA 317-2AJ12​ is its revolutionary SPEED7 ASIC. This dedicated hardware processor executes PLC instructions at an exceptionally high speed, dramatically reducing scan times compared to conventional microprocessors. This results in faster response to input signals, more precise control loops, and the ability to handle significantly more complex logic and data handling within the same cycle time. For applications involving high-speed counting, motion control, or rapid data processing, the performance boost offered by the CPU317SE 317-2AJ12​ translates directly into higher machine throughput, improved product quality, and the capability to manage more sophisticated automation strategies.Seamless integration and compatibility: A major advantage of the VIPA 317-2AJ12​ is its 100% hardware compatibility with the Siemens SIMATIC S7-300 system. It fits standard S7-300 mounting rails and connects to S7-300 I/O modules via the VIPA 300S backplane. More importantly, it is programmed using standard STEP 7 (TIA Portal compatibility depends on version) tools, allowing engineers to use familiar programming languages (LAD, FBD, STL, SCL) and reuse existing code libraries. This drastically reduces engineering time, training costs, and migration risks. The integrated communication ports provide versatile networking: the MPI/DP port allows for classic PROFIBUS-DP networks, HMI connections, and programming, while the integrated Ethernet port enables direct connectivity to modern industrial Ethernet networks for communication with HMIs, SCADA systems, and other higher-level IT systems, making the 317-2AJ12​ a bridge between classic and modern automation architectures.Robust design and flexible expansion: Built for industrial durability, the CPU features robust electrical protection and is designed for reliable 24/7 operation. Its modular nature allows the control system to be precisely scaled. The VIPA 317-2AJ12​ supports a large number of I/O modules on its backplane, and its substantial 1.4 MB work memory accommodates extensive user programs and data blocks. The use of MMC cards for load memory provides a reliable, non-volatile storage solution for the operating system and project data, and allows for easy program updates or controller replacement. This combination of performance, compatibility, and modularity makes the CPU317SE 317-2AJ12​ a future-proof investment that can adapt to evolving application needs.
