横川的植物资产管理解决方案PRM®（工厂资源经理）中央管理着大量的状态和维护信息，可以通过工厂监控和控制设备和设备管理。
PRM支持EDDL和FDT设备集成概念，并为过程自动化协议（例如HART，Foundation™FieldBus，Profibus和ISA100.11A Wireless）提供集成通信路径。使用PRM和智能现场设备，操作员和维护人员可以远程监控植物资产的状况，并可视化性能恶化的早期迹象，例如阀门粘附和基于D/P的脉冲线阻滞。
PRM features functions such as a device master function for maintaining an asset database and multiple views to visualize asset hierarchies according to IEC 61512 through Plant, Network or Class Views. The Device Patrol function uses a scheduler to periodically acquire device status information and features a status decision engine to display color coded information, including NAMUR NE107 functionality, on all hierarchy levels. In case of a diagnostic message the device DTM is launched to obtain detailed information and/or access device parameters.
PRM includes Yokogawa’s FDT2-based Frame Application, DTM Works, proven in many FieldMate™ Device Management Tool installations since 2014. DTM Works is compliant with both FDT2 and FDT 1.2.x DTMs. FDT2 provides improved security, interoperability, speed and performance along with backward compatibility. PRM R3.20 comes with the latest DTM’s for Yokogawa’s field devices including a suit of FDT2 DTM’s for the latest version of these devices.
Further, PRM features a Partial Stroke Test (PST) Scheduler, which was developed in close cooperation with leading valve suppliers. It collectively manages and performs partial stroke testing to determine whether ESD valves are in good working order and can respond properly when needed. The PST scheduler enables manual, automatic or semi-automatic implementation of a PST. Furthermore, the PST Schedule and implementation status are shown in a simple Gantt chart that can be viewed from any PC running the PRM package. Further analyses can be easily performed by opening the corresponding DTM.
