Supervision and fault management of process-tasks and terminology

The supervision of technical processes is aimed at showing the present state, indicating undesired or unpermitted states, and taking appropriate actions to avoid damage or accidents. The deviations from normal process behavior result from faults and errors, which can be attributed to many causes. They may result in some shorter or longer time periods with malfunctions or failures if no counteractions are taken. One reason for supervision is to avoid these malfunctions or failures. In the following article the basic tasks of supervision are shortly described.
