Open control-the standard for PC-based automation technology

Abstract

The industrial PC is playing an increasingly significant role in the field of control technology. These days, machine and system builders can compile their own automation solutions using hardware and software components from a variety of manufacturers. This opens up a whole new world of options for implementing manufacturer independent, cost effective automation solutions. In order to prevent possible interface problems in these open solutions, the open control user group has defined the CALL interfaces. These CALL interfaces enable simple data exchange, not only during the design phase, but also during the runtime of an automation solution. In addition, CALL enables access to distributed components via a fieldbus system such as INTERBUS (or other).
