Posted by Aron Semle

A PLC is unexpectedly offline, but the controls engineer doesn't know about itand once informed, cannot easily trace its root cause. A plant line is under performing, but the plant manager doesn't have any visibility into the factory lines to understand whyor how performance can be improved. A machine is out of its normal operating range, but the maintenance team doesn’t know the status of the anomaly—or what level of maintenance is needed to fix it
