Abstract

The present invention relates to analysis of sensors and sensor signals using status signals carrying information about the status of components in a flow system. The invention can comprise means for condition checking (31) arranged to determine the alarm state of a function connected via a condition to a goal when the goal is not achieved or means for checking for normal/failed situations (32) arranged to check a function in an alarmed state next to a function in a normal state using consequence propagation rules. Further, the invention can comprise means for full consequence irregularity analysis (33) arranged to assume that one of the alarm signals is erroneous, to check the alarm states using consequence propagation rules and to present the simplified situation if the number of primary alarms are decreased.
