Maintenance triggers
Maintenance triggers define the rules that determine when a maintenance procedure should be scheduled. In MES, multiple trigger modes are supported to allow flexible scheduling based on time, usage, or events.
Trigger modes
These are some typical scenarios that would trigger maintenance procedures:
- Period
- Schedules the procedure on a regular time basis, such as weekly, monthly, or quarterly.
- Counters
- Triggers the procedure based on asset usage, such as machine cycles or production volume, tracked by asset counters.
- Events
- Triggers the procedure based on specific detected events, such as a failed quality check or an OPC signal indicating abnormal behavior.
When multiple triggers are configured for a procedure, the first one to occur activates the procedure. Once triggered, all trigger conditions are reset.
Trigger configuration
These triggers can be defined with staged intervals:
- First due after
- The interval for the initial maintenance, such as 2 weeks or 10,000 cycles.
- Second due after
- The interval for the second occurrence, such as 6 weeks or 40,000 cycles.
- Then repeat every
- The interval for ongoing maintenance, such as every 3 months or 70,000 cycles.
This staged setup allows more frequent maintenance initially when new assets are deployed, then normalizes to a standard frequency. These flexible trigger modes ensure that maintenance is scheduled optimally to prevent breakdowns while minimizing unnecessary work.
