Industrial Ethernet offers a high-performance area and cell network to the IEEE 802.3 (ETHERNET) standard. Furthermore, Ethernet is the technology on which the Internet is based and offer the numerous advantages of worldwide networking. The wide range of possibilities offered by the Intranet, Extranet and Internet which are already available in the office environment can also be used in production automation and process automation. The already well-proven Ethernet technology in combination with Switching Full Duplex and Autosensing gives you the opportunity to match the performance in your network more precisely to the requirements. You can also select the data transmssion rate according to requirements because the system-wide compatibility permits step-by-step introduction of the new technology. Ethernet is, with its 80 % market share, the network No.1 in the LAN landscape worldwide. Ethernet offers important characteristics that can give you significant benefits for your application:

Fast start-up thanks to the simplest connection technique
High availability, because existing plants can be expanded without any adverse effects
Almost unlimited communications performance because scalable performance is available on request by means of switching technology
Networking of different application areas, such as the office and production
Communication throughout the corporation thanks to the coupling possibilities via WAN (Wide Area network) such as ISDN or the Internet
Investment security thanks to the constant compatible further developments

Profibus

PROFIBUS is the bus system for communication in small cell networks and with field devices. It is based on the IEC 61158/EN 50170 European Standard, Volume 2, PROFIBUS. In this way PROFIBUS ensures an open system for connecting the components of other manufacturers that conform to the standard.

PROFIBUS - the standard in field installations - comprises:

Defining the standards for the physical bus level and for access methods (layers 1 and 2 of the ISO Reference Model).
Defining the user protocol and the user interface PROFIBUS-FMS (layer 7) for communication between programmable controllers and field devices.
PROFIBUS-DP for fast, cyclic data exchange with field devices.

PROFIBUS meets the requirements for simple cabling in electrical and optical transmission technology. This makes it possible to cover great distances.

ASI

The AS-Interface bus system transfers process and machine-level digital and analog signals. Proximity switches, valves, indicator lights and other actuators and sensors can be linked over a 2-wire cable to PLCs, e.g. SIMATIC controllers or PCs. Data and supply voltage data are transported together over a single cable.

Advantages:

Minimum wiring and cost saving
Fast and safe installation
Flexible configuration
Open system
Integrated failsafe technology: Safety at Work
