Abstract:
1. A control and data transmission installation for redundantly controlling a slave device, comprising: at least two control devices; and at least one slave device which is connected with the at least two control devices via a communications network, wherein the at least one slave device has several addressable output interfaces for receiving output and status data, wherein each control device of the at least two control devices has a device for generating and transmitting status and output data to a separate output interface of the at least one slave device, and wherein the at least one slave device has an evaluation device, which, in response to the status data received from the at least two control devices, controls the forwarding of the output data that have been received for further use, wherein the evaluation device, upon receipt of the status data that signals a failure of one of the at least two control devices, forwards the output data coming from a properly operating control device, wherein the at least two control devices exchange the status data with one another, and wherein each control device of the at least two control devices transmits the status data to the output interface of the at least one slave device, the status data comprising an operating state of each control device.
