The fastest Hard-PLC worldwide with integrated Ethernet-CP 343

Herzogenaurach, (PresseBox) - The new SPEED7-CPU from VIPA is worldwide the fastest automation set of its kind and self-evident it is programmable with STEP7 from Siemens. This CPU is created for time-critical applications and fulfils at the same time the demands for increasing memory capacity. The memory could be dynamicly adapted additionally to the demands of the plant/application every time, without the need of exchanging the existing hardware. Thereby the number of the needed CPU types - which the customer has to insert in all applications - reduces to one.

There is a integrated High-Speed-Ethernet-CP 343 with RFC1006, S7-Communication, H1, TCP/IP, Modubus master, USS master and UDP available. This CP is projectable with NetPro up to 16 connections; with FB55 IP_Config up to 64 connections (depends on CPU version).

General informations of SPEED7 technology

The CPU with SPEED7 technology is the first PLC which is configurable via MMC (Memory Configuration Card) for a large memory area. Of course, the functions of the previous VIPA MMC, beside the scaling of the memory, are still available ¨C e. g. as a external data memory for scources and programs as well as for the firmware updates. The standard MMC card could be used for storing of programs and data during for the running of the CPU. For the operating of the CPUs the memory card is not necessary.

Profibus is available as integrated fieldbus interface. Furthermore the MPI interface with 12Mbaud is included.

In addition the SPEED7-CPUs possess an integrated Ethernet-interface which offer convenient programming via network to the user.

Peripherals can be connected in two ways:

1. Serial connection as usual on the right side via S7-300-Standard Backplane Bus, at which all S7-300-I/O-modules as well as partly communication processors and function modules like counters are to be operated.

2. The special feature of CPUs 314ST/317 is the parallel connection via VIPA Highspeed parallel bus on the left side of the CPU, which offers the possibility to use special fast peripherals. For the Highspeed parallel bus VIPA is offering digital in-/ outputs, fast analog inputs, FAST Profibus-DP, INTERBUS-Master as well CAN-Interface (see relating list of VIPA), Ethernet CP 343.

With the integrated Master for Profibus-DP, the Ethernet-Interface and the MPIInterface VIPA is supporting all important interfaces in one system.

VIPA Gesellschaft für Visualisierung und Prozeßautomatisierung mbH

VIPA was founded in 1985 in Erlangen by Mr. Wolfgang Seel as a system house for automation engineering. After the first PC-based machine operating panel there were further developments of control and communication modules. The first customers were from the automotive and food industry, conveying engineering and machine and plant construction. VIPA has been increasingly active in the European market since 1995.

The introduction of the modular automation System 200V was the basis for creating more powerful, faster and more reliable systems. In the year 2000 the new 2000sq.m headquarter in Herzogenaurach, west of Erlangen was opened.

The development of the SPEED7 High-SPEED PLC in 2003 was a further technological milestone in the automation equipment range (www.speed7.com). In 2005, VIPA has extended the product range with the Touch Panel family.

More than 100 highly qualified employees are working for VIPA in Germany. In addition to that there are VIPA branche offices and Service partners in 55 countries.
