The invention relates to a device and method for automatically controlling a technical system (54) operation. The inventive device comprises a first control unit (12) for generating first control commands (24) for initiating an operation. A second control unit (14), preferably error-protected, is used for generating second control commands (26) for carrying out safety functions. Said device also comprises at least one controlled actuator (46, 48, 50) and an I/O unit (16) which is remote from the first (12) and second (14) units. Said I/O unit (16) drives the actuator (46, 48 50) and is connected to the first control unit (12) by means of a first interface (40). In one embodiment, said I/O unit (16) comprises a second interface (42) for connecting to the second control unit (14) and drive the actuator (46, 48, 50) according to the first and second control commands (24, 26). |
