Product Overview
The VIPA 317-2AJ12, officially designated CPU 317SE/DPM, is a high-performance central processing unit from VIPA’s System 300S family, built on the company’s proprietary SPEED7 technology. In practical terms, it is a drop-in processor for the mechanical and electrical environment of a SIMATIC S7-300 rack: it occupies a standard S7-300 slot, is powered from the same 24 V DC supply, addresses the same backplane bus, and is configured with the familiar STEP 7 engineering toolchain, yet executes the user program with the speed and memory headroom of a considerably higher tier of controller. This combination is precisely why the VIPA 317-2AJ12 became a popular choice both for new machine builds that needed headroom and for retrofit projects where an existing S7-300 installation had run out of performance.Inside the module, a SPEED7 processor with a separate communication and programming coprocessor drives bit, word and double-integer instructions in approximately 0.01 µs and floating-point operations in 0.06 µs, backed by 2 MB of integrated work memory that can be extended to 8 MB and 8 MB of integrated load memory with an MMC card slot accepting up to 1 GB. Communication is equally well provisioned: the VIPA 317-2AJ12 carries an integrated PROFIBUS-DP master interface at up to 12 Mbps with support for 125 slaves, a switchable PtP RS485 port for serial protocols, an MPI interface at up to 12 MBd, and an Ethernet PG/OP port for programming, operator communication and S7 communication.A distinguishing feature of this CPU is the SPEED-Bus, a high-speed parallel bus on the left-hand side of the module to which dedicated high-speed I/O modules can be connected, bypassing the bandwidth limits of the standard serial backplane. Combined with support for up to four racks, 8192 bytes of input and output address area, 2048 timers and counters, and a buffered real-time clock, the VIPA 317-2AJ12 is positioned as the controller of choice for medium to large automation tasks where cycle time, I/O density and communication load all matter at once.
