Product Overview
The VIPA 317-2AJ12, officially designated as the CPU 317SE/DPM-SPEED7, is a high-performance central processing unit from the VIPA System 300S series, engineered for demanding industrial automation applications. Manufactured by VIPA GmbH (now a Yaskawa company), this processor module is built upon the proprietary SPEED7 technology, a 32-bit RISC processor architecture that delivers exceptional instruction processing speeds of just 0.01 µs per operation. The VIPA 317-2AJ12 is strategically positioned as a high-speed alternative to traditional PLC CPUs, offering significant performance advantages while maintaining broad compatibility with the widely adopted Siemens S7-300 ecosystem.
At the core of the 317-2AJ12 lies a dedicated SPEED7 chip with integrated programming and communication coprocessors, enabling it to execute 100,000 instructions per millisecond. This makes the VIPA 317-2AJ12 one of the fastest rack-mounted PLC CPUs available, ideal for time-critical control tasks that demand ultra-fast cycle times. The module features a substantial 2MB work memory (expandable to 8MB via MMC card) allocated as 50% program and 50% data, along with an integrated 8MB load memory. The CPU 317SE/DPM designation confirms its integrated PROFIBUS-DP master capability and point-to-point RS485 interface, providing versatile communication options for distributed automation systems.
As a legacy product that has been officially discontinued by the manufacturer (with the official replacement being 317-2AJ23), the VIPA 317-2AJ12 remains a critical spare part for facilities operating existing System 300S installations. Its hardware compatibility with the Siemens S7-300 backplane bus and software compatibility with STEP 7 programming environments make the 317-2AJ12 an exceptional choice for system expansions, upgrades, or emergency replacements in mixed-vendor automation environments.
