ABSTRACT:
A method for operating a process plant, in which at the process level a number of items of alarm information are generated to display improper operating procedures of the process plant, hasa defined number of process states of the process plant, whereineach process state is correlated with the total of all items of alarm information that can be generated. A first value or a second value is allocated as the correlation value to each pair formed from a process state and an item of alarm information.A current operating state of the process plant is determinedAs a function of the determined process state, items of alarm information are not displayed to which the first value has been allocated as the correlation value.
