Yokogawa has released an upgrade of its Plant Resource Manager (PRM). PRM R3 is a key component of Yokogawa's Asset Excellence suite that integrates and manages maintenance information from field instruments, monitors online conditions and records historical data from these field devices. PRM R3's enhanced diagnostic function transforms maintenance activities from corrective maintenance to predicative and proactive maintenance. It also enables users to remotely access devices that feature field communication capability as well as perform centralized management of the parameters of those devices. Information such as the names of flow meters, valves, parameter settings, inspection records and instruction manuals are stored in a database (Microsoft's SQL server). PRM R3 incorporates and takes advantage of both FDT/DTM (Field Device Tool/Device Type Manager) and EDDL (Enhanced Device Descriptor Language) technologies.
