There is described a method for operating an automation system which comprises at least two measuring modules, each connected to a higher order processing unit in order to communicate therewith. The higher order processing unit is informed of an event that is recorded by one of the at least two measuring modules. The processing unit then informs any available measuring module of the event.

Method for operating an automation system

There is described a periphery unit for an automatic device, which can be actuated as an analog input and as an analog output. A number of connections which are to be used as inputs and the number of connections which are to be used as outputs can be adapted in a flexible manner on the respective application from a predetermined number of connections of the periphery unit. As a result, a redundant automatic device wherein said types of periphery units can be used, is provided.

Redundant control system having a peripheral unit for an automation device

A method for preventing or minimizing operational failures in a technical installation () is disclosed, in which, in accordance with influence quantities () accessible by a control system, at least one criterion () is defined so as to forecast an impending failure of one or more parts of the installation. This criterion is constantly monitored at short time intervals so as to establish a forecast of the expected failure probability. This forecast makes it possible, if necessary, to take early countermeasures () for preventing the failure of the installation or to take steps for minimizing the effects of the imminent failure.
