Abstract
A safety controller for controlling an automated installation has a control unit to which a plurality of control input signals are supplied from the sensors of the installation. The control unit produces a plurality of control output signals on the basis of the control input signals in accordance with a user program running in said control unit in an automatic mode. The plurality of control output signals actuate the actuators. The safety controller also has a diagnosis evaluation unit that ascertains which one of a plurality of operating states is present at a defined instant of time and produces an operating state signal which represents the ascertained operating state. A diagnosis selection unit generates a diagnosis report as a function of the operating state signal and as a function of a user access authorization signal and/or a special operating mode signal. The diagnosis report representing the ascertained operating state thus varies depending on specific circumstances, such as a certain user access authorization or a certain operating mode.
