Abstract
Meeting the safety requirements of automation systems in a more flexible manner, the invention provides a control and data transmission system for controlling safety-critical processes comprising a plurality of I/O modules connected via a first communication network to a gateway module. The gateway module is connected to a second communication network hierarchically superior to the first communication network and acts as a gateway between the first and the second communication networks. At least one of the I/O modules comprises a diagnosis unit for generating status data relating to the functional state of an input and/or output and/or of a process device. The gateway module and the I/O modules communicate via the first communication network in a safe manner to transfer status data and input and/or output data. The gateway module performs safety processing of the status data and/or of the input and/or output data.
