<p>In a process plant, a mobile device (112, fig 1) detects a physical phenomenon, e.g. light, flame colour, vibration, sound and converts it to a digital data representative. The data are transmitted to an expert system and analyzed to determine a state of one or more process elements. Abnormal conditions associated with the process elements may be detected, and a cause of the abnormal condition may be determined from the digital data. Process control parameters may be automatically changed to correct the abnormal condition, work items may be created to cause personnel to take action to correct the abnormal condition, and/or an operator may be prompted to take a corrective action to resolve the abnormal condition.</p> |
