Maintenance and Failure

3min

The Maintenance and Failure KPI mainly deals with the maintenance event and a fault/failure event in a production cycle.
Maintenance and Failure Overview
For Maintenance events per cycle, you can see the number of maintenance events (planned or unplanned) in a production cycle.
For Time since last maintenance, If you know that a machine needs to be checked periodically, you can see the time elapsed between maintenance events.
Timestamp of last maintenance is used to keep track of the previous time maintenance occurred.
For Number of faults / failures detected in a period, you can see the number of failures that have occurred in a period.
For Time since last failure, if you know that the machine needs to be checked periodically, you can see the time elapsed between failure events.
Timestamp of last failure is used to keep track of the previous time when a failure occurred.
The timer interval parameter is useful if the connected input tag is offline but you still want this KPI to look for a value every few seconds, defined by the timer.
Within the KPI you can define how you want to trigger the mechanism of a maintenance event, and a failure event.
For example, if you define Maintenance From: 0 and Maintenance To: 1, this means that when the value from the input tag, with the definition on the connection as maintenance, goes from 0 to 1, it is an indication that there was a maintenance event.
Failure From: 2 and Failure To: 4 means whenever the input tag the definition on the connection as *failure *goes from 2 to 4, it is an indication that there was a failure event.
Maintenance and Failure Parameter
Parameters
Details
Maintenance From
This parameter specifies the value at which a maintenance event is considered to be triggered.
Maintenance To
This parameter specifies the value at which a maintenance event is considered to be completed.
Failure From
This parameter specifies the value at which a failure event is considered to be triggered.
Failure To
This parameter specifies the value at which a failure event is considered to be completed.
Unit
This parameter allows you to select the time unit in which the time since the last Maintenance/Failure will be displayed (Seconds, Minutes, Hours, Days, or Weeks).
Timer Interval
Timer in milliseconds. If no event, use this timer to keep displaying the output continually. Enter zero to disable.
