Main Features and Advantages
Unmatched processing speed and efficiency: At the core of the VIPA 317-2AJ12 lies the SPEED7 technology, which processes bit and word instructions in just 0.01 µs, and double integer operations at the same speed . This is significantly faster than many comparable CPUs in its class, making the CPU 317SE/DPM ideal for applications with tight cycle time requirements. For demanding mathematical operations, the floating-point instruction executes in 0.06 µs, ensuring that even complex calculations do not become a bottleneck in your control loop.
Integrated PROFIBUS-DP master and flexible communication: The VIPA 317-2AJ12 is a robust master capable of controlling up to 125 slave devices on a PROFIBUS-DP network at speeds up to 12 Mbit/s . This integrated DP master eliminates the need for an additional communication processor (CP), simplifying your hardware setup and reducing costs. The same physical RS485 interface can also be configured for point-to-point ASCII communication, allowing the VIPA 317-2AJ12 to connect directly to serial devices like barcode readers, displays, or other controllers without requiring a gateway.
Ample memory and expansion for complex programs: With a total work memory of 2 MB, the VIPA 317-2AJ12 provides substantial space for program code and data. Should your application outgrow this capacity, the memory can be expanded to a maximum of 8 MB via an MMC card . This scalability ensures that the CPU 317SE/DPM can grow with your system. The integrated Ethernet PG/OP interface allows for convenient remote programming and diagnostics.
Compatibility and differentiation with SPEED-Bus: One of the most distinctive hardware features of the VIPA 317-2AJ12 is the integrated SPEED-Bus, a proprietary 32-bit parallel bus developed by VIPA. This bus, separate from the standard S7-300 backplane, can connect up to 10 dedicated high-speed I/O modules, achieving a data rate up to 40 MB/s . This is ideal for high-speed acquisition and fast-response scenarios. The VIPA 317-2AJ12 also retains compatibility with the standard serial backplane bus, allowing you to mix VIPA and standard S7-300 modules on the same rack .
