The most favorable merit for applying fieldbus is high efficiently maintenance of field devices. For this purpose, a software package Plant Resource Manager (PRM) is added to software lineup. With this PRM package, the advantage of fieldbus can be utilized so as to make the maintenance of the whole system more efficient.

PRM: Plant Resource Manager

The maintenance information of devices are collected by PRM via fieldbuses and stored in the PRM database. The corresponding maintenance schedules, maintenance procedures and spare parts information are also stored accordingly in the same database. The maintenance of the field devices can be performed though fieldbus. Thus the maintenance engineers are considerably relieved from going to the fields of the devices in the remote areas and hazardous areas.

Audit Trail

Audit trail management is important in both control and maintenance systems. All maintenance works on devices, which are maintained by PRM, are recorded and stored, and can be easily retrieved too.

Predictive Maintenance

By integrated management of device management information, the replacement cycle of devices and trend of device troubles can be predicted. This technique minimizes the impact of device problems on plant operation, and maintenance work and parts procurement can also be planned and scheduled.

Solutions to Non-Fieldbus Devices

PRM can create a database for legacy devices in addition to Fieldbus devices. Maintenance information is recorded and managed in a database for integrated, overall planned maintenance of all devices in the plant.
