VIPA 315-2AG12​ CPU 315SB/DPM SPEED7 Processor Module with Integrated PROFIBUS DP Master

Technical Specifications

Main Features and Advantages

SPEED7 processing headroom: The defining advantage of the VIPA 315-2AG12​ is raw execution speed. With 0.01 µs bit and word instruction times, cycle times collapse compared with a conventional 315-class CPU, which means faster closed-loop response, tighter registration and cut-to-length accuracy, and the freedom to add diagnostics, recipe handling and data logging later without having to re-platform the controller.Integrated PROFIBUS DP master, no extra CP module: The 315-2AG12​ drives a full PROFIBUS DP network at 12 Mbit/s with up to 125 distributed slaves, covering remote I/O, drives, valve islands and weighing electronics. Because the master is on the CPU, the rack slot, the hardware cost and the configuration work of a separate communication processor are all eliminated.Dual-purpose RS485 and built-in Ethernet PG/OP: The RS485 port can be committed either to the DP master or to serial PtP communication with bar-code readers, scales, analysers and legacy instruments using ASCII, 3964(R), USS or Modbus. Independently, the RJ45 Ethernet PG/OP channel gives programmers and HMI stations always-available access for download, online diagnostics and the internal web page, without consuming a slot.Flexible memory and retentive real time clock: One MByte of work memory, split 50/50 between code and data and expandable to two MByte with an MCC card, together with 2 MByte of load memory, gives room for large sequential programs and extensive data blocks. The battery-buffered real-time clock keeps time-stamped alarm and event logging accurate through power loss, which is essential for traceability and root-cause analysis.Drop-in S7-300 compatibility: The VIPA 315-2AG12​ mounts on a standard S7-300 profile rail and exchanges data over the familiar serial backplane bus, so existing racks, power supplies and I/O modules are reused. Projects are engineered in STEP 7, TIA Portal or WinPLC7, which protects a plant’s software investment and keeps commissioning time short.

Application Field

Machine and production line control: The VIPA 315-2AG12​ is at home on packaging machines, conveyors, assembly stations and press lines where short cycle times and a large distributed I/O footprint must coexist. Its integrated DP master lets a single CPU coordinate remote I/O islands, frequency converters and valve terminals along a line without an additional communication processor.Process and utility automation: In water and wastewater treatment, chemical dosing, HVAC plant rooms and energy distribution panels, the module’s 512 timers, 512 counters and time-stamped event handling support shift-based sequencing, pump alternation and energy reporting, while the PtP port integrates analysers and flow meters that speak Modbus or ASCII.Retrofit and life-extension projects: Because the 315-2AG12​ is mechanically and electrically S7-300 compatible, it is frequently specified as a performance upgrade for ageing SIMATIC racks where the original CPU has become a bottleneck or is no longer procurable. Existing I/O wiring, field devices and step 7 project code are largely preserved, so downtime and re-engineering cost stay low.High-speed and data-intensive tasks: Applications involving high-speed counters, registration control, sorting and batch recipe management benefit from the SPEED7 execution rate and the expandable work memory, giving OEMs room to grow functionality over the machine’s service life.Industries served: Automotive and tier-one suppliers, food and beverage, pharmaceutical and chemical processing, water and wastewater, material handling and logistics, printing and converting, metals, and building services. In every one of these sectors the VIPA 315-2AG12​ is chosen when an installed PROFIBUS-based architecture needs more performance without a migration to a new platform.
