Monitoring of a system
First Claim
1. A method of monitoring a system, which includesdetermining the values of a number of parameters of equipment comprising the system;
- determining from the values when the parameters become abnormal and when they become normal;
recording those parameters that become abnormal and those parameters which were abnormal and become normal and the times at which these events occurred;
grouping the parameters in a plurality of different categories in accordance with the nature of the parameters;
determining the number of abnormal parameters in each category in a plurality of predetermined time intervals for each of the time intervals; and
displaying, for a predetermined time window which incorporates said plurality of time intervals, the number of abnormal parameters in each category in each time interval.

Abstract
A method of monitoring a system, includes determining the values of a number of parameters of equipment comprising the system. The values when the parameters become abnormal and when they become normal are determined. Those parameters that become abnormal and those parameters which were abnormal and become normal and the times at which these events occurred are recorded. The parameters are grouped in a plurality of different categories. The number of abnormal parameters in each category in a predetermined time interval is summarized. The number of abnormal parameters in each category in each time interval is displayed for a predetermined time window. The invention also extends to an arrangement for monitoring a system.
