Abstract: Communication data streams are transmitted within the scope of a multipoint connection from a first terminal to other terminals. The first terminal distributes communication data streams originating at the first terminal and received from the other terminals involved in the multipoint connection. As a result, each of the other terminals receives the communication data streams originating from the other terminals.

Abstract: An electronic control device for a modular valve range, which has a fluid manifold arrangement fitted with electrically controlled valves. The valves are controlled via at least one control module. Furthermore input and/or output modules and a central electronic control unit are provided, with which the individual modules are connected for control and/or data communication. The control unit is connected with the modules via a bus line system and each module possesses a programmed address decoder, means being provided for sequential configuration of the modules and for the automatic assignment of individual addresses for the individual modules. Accordingly the valve range may be designed and expanded just as may be desired, the connected modules automatically being recognized and provided with addresses.

Abstract: A valve range is suggested suitable for use in connection with the control of fluid operated equipment. It possesses a fluid manifold, which is able to be fitted with pneumatic valves, which are operated via a signal manifold electrically. The valve range is so designed that it is suitable for the combined operation or control both of pneumatic valves and also of hydraulic valves. For the control of hydraulic valves it is provided with at least one control connection, from which the respective control signals may be taken. It is in this manner that, starting with a central valve range both pneumatic and also hydraulic valves may be operated and controlled in a comparatively simple fashion.
