Siemens’ Simatic Maintenance Station software now offers functions for the efficient planning and monitoring of maintenance operations and jobs. It also allows devices in the field to access the Simatic Maintenance Station via a web client for remote maintenance. Simatic Maintenance Station, a software option for the Simatic WinCC SCADA system, supports preventive, condition-based, and reactive maintenance activities of a plant in a central system. The software visualises diagnostic and maintenance information - from a PC to network components all the way to controllers, switching, protection, and control units, as well as drives. The plant operator receives a uniform and clear status display.
