Product Overview

The VIPA 315-2DP01​ is a powerful, standalone CPU (Central Processing Unit) module, central to VIPA’s 300S series of SIMATIC S7-300 compatible programmable logic controllers. This module, officially designated as the VIPA CPU315-2DP, is engineered to deliver high-performance control for a wide range of mid-to-high-level automation tasks. It features a native, high-speed PROFIBUS-DP interface integrated directly onto the module, allowing it to function seamlessly as either a DP master for controlling distributed I/O networks or as a DP slave within a larger automation hierarchy. The VIPA 315-2DP01​ is renowned for its execution speed, significantly outperforming many CPUs in its class due to VIPA’s optimized hardware architecture, which includes a fast ASIC processor and efficient memory management. This makes it an ideal choice for applications requiring rapid scan times and complex data processing, from sophisticated machine control to supervisory process automation.As a core component of a modular PLC system, the VIPA 315-2DP01​ provides extensive memory for user programs, data, and configuration, supporting the development of intricate control strategies. Its design philosophy centers on compatibility and performance, allowing engineers familiar with Siemens STEP 7 programming environments to leverage their existing knowledge, as the module is programmed using standard STEP 7 (or VIPA’s own WinPLC7) software. The module’s integrated MPI/DP combo port also provides Multi-Point Interface (MPI) connectivity for programming, HMI communication, and simple peer-to-peer networking. The value of the VIPA CPU315-2DP 315-2DP01​ lies in its potent combination of high-speed processing, robust integrated PROFIBUS networking, and cost-effectiveness compared to some OEM alternatives. It serves as a reliable and powerful automation brain, capable of managing complex I/O structures, executing PID loops, and handling communication tasks, all while offering a smooth migration or alternative path for users within the S7-300 ecosystem.

Technical Specifications

Main Features and Advantages

The VIPA 315-2DP01​ CPU module is distinguished by its exceptional processing speed and versatile, high-performance communication capabilities. Its most prominent feature is the integrated PROFIBUS-DP interface, which operates at speeds up to 12 Mbps. This allows the 315-2DP01​ to act as a Class 1 DP master, efficiently controlling large networks of distributed I/O stations, drives, and other field devices, or to integrate as a intelligent slave into a superior control system. The second communication port serves as a configurable MPI/DP interface, providing flexibility for programming, operator panel connection, or setting up a second, lower-speed PROFIBUS network. This dual-port capability offers significant design flexibility for building multi-tiered network architectures without requiring additional communication processors.A key competitive advantage of the VIPA 315-2DP01​ is its raw execution speed, driven by VIPA’s proprietary Speed7 technology. This results in very fast bit instruction processing times and short overall scan cycles, which is critical for high-speed machine control, fast closed-loop control, and applications requiring precise timing. The CPU supports a large number of function blocks (FBs), function calls (FCs), and data blocks (DBs), enabling well-structured, modular, and reusable programming. Program and data retention are managed via a removable Micro Memory Card (MMC), which provides a robust, non-volatile storage solution superior to battery-backed RAM. The module is fully compatible with the Siemens S7-300 I/O module ecosystem, allowing for the creation of cost-effective, high-performance hybrid systems. The combination of blistering speed, powerful integrated networking, and deep S7-300 compatibility makes the VIPA CPU315-2DP 315-2DP01​ a highly capable and efficient automation controller that delivers premium performance for demanding applications.
