Maintenance Task Types¶
This section explains the two maintenance task types - Scheduled Maintenance and Maintenance Issue - how they are created, and how they are managed.
Scheduled Maintenance¶
Scheduled maintenance tasks are based on the Service Cycle, DTCs, faults, or other regular intervals and are implemented by the manufacturer via the Maintenance Planner. A task becomes due once its Threshold is reached, see Task Detail.
Calendar-based Maintenance¶
Scheduled maintenance tasks can also be triggered by a calendar interval instead of, or in addition to, a signal such as operating hours. If both are configured for the same maintenance item, the task becomes due whichever target is reached first.
The target date is calculated from the machine's activation date and the configured interval, defined via the Maintenance Planner. If the machine's Commission Date is available, it is used as the activation date.
See Table View and Card View for how the Date threshold is displayed.
Hours-to-next-service¶
Scheduled maintenance tasks can also be based on hours-to-next-service instead of an incrementing operating hours counter. In this case, a decrementing, resetting signal is used to create the next maintenance task.
For hours-to-next-service tasks, the Latest value is always positive, and so is the Service in value, unlike for regular Scheduled Maintenance tasks. The Threshold is not displayed, as the signal value counts down to zero and showing 0 as a threshold does not provide meaningful information.
Consider that in the Machine Companion App Manual, a mix of maintenance tasks based on the signals hours-to-next-service and operating hours is used.
Maintenance Issues¶
Unscheduled tasks, so-called Maintenance Issue, are created for tasks that need to be done in between service cycles — for example, based on DTCs or wear-based components, or manually by manufacturers and machine owners using the REST API call Create Maintenance Task.
Dealers and machine owners are able to view and manage tasks, such as adapting the state or adding a Completion Note.
Both scheduled and unscheduled maintenance tasks undergo the same progress from Unplanned to Completed and can have the same deadlines Upcoming and Overdue.
