A method for configuring and parameterizing field bus subscribers interconnected via a field bus, wherein a first field bus subscriber provides and/or receives process data and a second field bus subscriber allows a user program to run, where a topology is determined by a configuration tool with configuration parameters of the field bus subscribers in a configuration file, the first field bus subscriber is parameterized for subsequent communication via the field bus with a configuration data set including a first part of the configuration file, from the configuration file and further code portions from a program library, an object-orientated class is generated with elements and functions for communication between the first and second field bus subscribers, and the class is instanced in the user program of the second field bus subscriber, the functions being used for communication during execution of the user program to permit access to the process data.

Engineering system and method for configuring and parameterizing field bus subscribers

A data bus coupler has a primary bus connection for a primary bus and a plurality of secondary bus connections each for a terminal. The coupler includes a slave unit connected to the primary bus connection and a master unit connectable to the secondary bus connections and configured for sending telegrams to and receiving telegrams from the secondary bus connections, and a control unit. Communication switching means, under control of the control unit, connect each secondary bus connection to/from the master unit.
