Components has to repair and maintain often in the field. Sometimes people has already detect faults for example, visible leaks, deviations in machine sounds before the actual fault alarm. Therefore, human needs to be involved in preventive maintenance, when managing field equipment and devices.
When human-made observations are reported, the system immediately moves the information forward and can begin to resolve the problem before it occurs. This way, the number, location and availability of the components on the field are known by all. Users’ searches remain in the user history and provide important data about the operations in the field.
