Abstract
A safety controller for controlling an automated installation in accordance with a user program has a control unit receiving a plurality of control input signals from a plurality of sensors. The control unit produces a plurality of control output signals on the basis of the control input signals in accordance with a user program. The control output signals drive actuators in order to adopt one of a plurality of installation states of the automated installation. An installation diagnosis evaluation unit produces a number of installation state signals representing which one of the plurality of installation states is existent at a defined moment of time. In addition, a system diagnosis evaluation unit produces a number of system state signals, with each system state signal representing one from a plurality of operational system states of the controller system, which is formed by the control unit and its connected sensors and actuators, at the defined moment of time. A diagnosis report unit produces a number of diagnosis signals depending on the installation state signals, depending on the system state signals, and depending on predefined associations between said installation states and said operational system states. The diagnosis signals represent a number of diagnosis reports which are a result of a combination of both the installation states and associated operational system states. A display unit displays the diagnosis reports in response to the diagnosis signals.
