Use a built-in dictionary of the machine states. The ANT system compares ideal cycle time with current results. When a production delay occurs, the system retrieves data from the PLC on the cause of the downtime or asked the operator to point it out. The administrator decides when the micro-stop is changing to downtime. Once the reason for the stop has been identified (failure, quality issue, lack of materials, etc.), the services concerned will be asked to react.
