Vipa is now offering new versions of its Touch Panel family of operator panels with an integrated PLC powered by its leading-edge Speed7 processor technology, compatible with Siemens Step7
Low cost, compact PLC for small fast automation
The new compact, fixed I/O PLCs based upon Vipa Speed7 technology offer the fastest PLC programmable with Siemens Step7: giving ultra high speed solutions for small automation applications
The Speed7-CPU has been designed for time critical automation applications with a processing capability of over 50K instructions in under 1ms, far outstripping other PLCs available today with over four times the overall performance of the Siemens S7-416.
The new system also features a unique modular memory system, known as MCC (Memory Configuration Card) which allows scalability for both large and small automation projects.
Users purchase only the memory they require for their application and if and when their requirements change, additional memory can be purchased without hardware changes.

PLC is fastest Step7 solution available today
The System 500S, PC based PLC is part of a range of automation solutions from Vipa that are fully compatible with the Siemens Step7 programming language but offer faster processing speeds
This keeps costs to a minimum with the added advantage that the Speed7-CPU PLC can be applied across a wide range of automation applications from small to the very largest with the clear benefit of programmers and engineers gaining familiarity with just one system for all their needs.
In addition to increasing memory, the swappable MCC card offers users a convenient way to store source code, programs and firmware updates.
The Speed7-CPU system is available in four models covering a wide range of interfacing and packaging requirements extending to Profibus DP (Master) and Ethernet CP343, MP2I and USB-B with din rail and backplane mounting as well as a PCI-board based version.
Peripheral cards for I/O, fieldbus and power supplies can be selected from the comprehensive VIPA System-300V range (pin-compatible with Siemens S7-300) for the majority of requirements and third party modules can also be added for specialist needs such as servo drives.
Additionally a new ultra-fast, parallel bus known as VIPA-Speed-Bus is available on certain models allowing options such as Fast Profibus-DP, Interbus-Master, CANopen-Master/Slave, CP 343 Ethernet as well as high-speed digital and analogue inputs for registration and very precise control requirements.
This dual interfacing system is unique to automation devices in this class and will allow for up to 32 VIPA System 300V modules on the serial bus in combination with 16 parallel VIPA Speed modules offering a truly versatile and flexible automation platform.
Compatibility with Siemens Step7 extends to SFCs and OBs and as some 25% of PLCs use this well-accepted programming language (Siemens quoted figure), the minimal cost to switch to the faster system and the availability of programmers familiar with the language will certainly not pose any problem to existing users.
Programming is also possible with other Siemens languages such as LAD, FBD, STL, SCL, Graph7 as CPU-Type 300 or 400 as well as WinPLC7 from VIPA.
Minimum processing times for bit operations are 14 ns, word operations: 14 ns, fixed point arithmetic: 14 ns and floating point arithmetic: 84 ns.
Execution time for a typical 100K instruction mix is typically 2.1 ms.
These results have been established using a calibrated Step7 program which has also been benchmarked against a selection of Siemens S7 PLCs; the results and complete specifications for the Speed7-CPU range are available via the website.
VIPA GmbH was created in 1985 by Herr Wolfgang Seel in Erlangen, Germany, as a system house for automation and control engineering.
By 1988, project related automation solutions led to the design and manufacture of their first PC based machine controllers and PLC systems for S5 from Siemens with TCP/IP communication.
1997 saw the launch of the System 200V which has become a respected and established product in the German automation market.
Today VIPA are a recognised force in automation systems and have a successful and growing world-wide base of distribution and subsidiary companies supporting its full product range.
With innovative design and a strong emphasis on cost and performance, VIPA are planning to provide the UK market with ground-breaking and competitive machine control solutions.
In addition to the new Speed7, VIPA's extensive range includes PLC and PC based automation solutions for centralised and decentralised control for the majority of fieldbus systems.
Current VIPA products include the System 100V, 200V, 300V and 500V which offer varying levels of performance from small and simple to extremely complex machine control applications for modular DIN rail and PC slot mounting.
The majority of VIPA PLCs are pin and instruction set compatible with Siemens S7-300 and S7-400, and are programmable with Step7 from Siemens as well as WinPLC7 from VIPA.
Some models are compatible with older Siemens S5 based PLCs, such as the S5-115U/135U/155U.
All ranges offer CPUs with memory expansion, fieldbus expansion modules, function modules, digital and analogue I/O modules, terminals, HMI and an extensive array of accessories including a diagnostic Profibus connector, to support integration into new or existing applications.
