PM-MAINT permits mapping of the hierarchical plant structure of the company down to the level of the smallest units for maintenance. Maintenance jobs can be created for each maintenance object.

Maintenance planning and activation

In the case of performance-dependent maintenance, PM‑MAINT utilizes operating hours and switching cycles from the current process data to calculate the recommended maintenance dates. When these dates are reached, PM‑MAINT automatically creates the maintenance job. Additional options for creating maintenance jobs are process events or calendar intervals (days, weeks, months, quarters, years).

Assignment of documents

Any documents can be added as supplementary information to each maintenance object or job in the object tree, e.g.

• Dimension drawings
• Technical specifications
• Maintenance information

Job recording/checklists

Maintenance jobs can be recorded manually or automatically. These reports are then used by the maintenance personnel as a checklist. Lists with ordering data for material requirements planning are additionally available for printing depending on the job. Processing of measures can also be documented in a report.

Material and personnel assignment

The required material and personnel resources can be assigned to the maintenance jobs. The materials and working hours actually required can then be entered in the feedback relating to maintenance activities.

Archiving and analysis

All maintenance activities are saved in an archive which is permanently evaluated to achieve a continuous improvement in maintenance procedures. Unexpected maintenance jobs can be recorded manually or by means of the SIMATIC PCS 7 Maintenance Station, and integrated into the long-term archiving.
