Control and data transmission system for redundant control of slave device, has slave device with evaluation device for controlling transmission of received output data for further use in response to status signal
Control and data transmission system for redundant control of slave device, has slave device with evaluation device for controlling transmission of received output data for further use in response to status signal
The system (10) has two control devices (20, 30) and a slave device (40) connected to each other by a communications network (70). The slave device has a set of addressable output interfaces (61, 62) for receiving output and status data. Each control device has a device for generating and transmitting status and original data to a separate output interface. The slave device has an evaluation device (60) for controlling transmission of the received output data for further use in response to a status signal received from the control devices. An independent claim is also included for a method for redundant control of a slave device.
