Yokogawa Releases Plant Resource Manager (PRM) Version R3
Device Maintenance and Management Software

Yokogawa announces that it has released a new upgrade of its Plant Resource Manager (PRM™) R3. 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. 

PRM enables users to remotely access devices that feature field communication capability -- such as FOUNDATION fieldbus™- and HART-enabled devices -- as well as perform centralized management of the parameters of those devices. These functions provide efficient management and maintenance of field devices and computerization of maintenance data that streamlines maintenance operations and achieves cost savings. Information such as the names of flow meters, valves, and other field instruments, parameter settings, inspection records, and instruction manuals are stored in a database, which the operator can easily access as necessary. PRM R3 is the first asset management package released in the world that incorporates and takes advantage of both FDT/DTM (Field Device Tool/Device Type Manager) and EDDL (Electronic Device Descriptor Language) technologies.

Major features of PRM R3 are as follows:


Compatibility with FDT/DTM and EDDL - A World First
Support of the FDT/DTM open interface technologies allows PRM R3 to make maximum use of field instruments'sophisticated and complex functions for performing device settings, adjustments, and self-diagnostics.

(2) Enhanced Diagnostic Functions
The historian function enables the collection and saving of instrument diagnostic data, trend analysis based on past trend information, and function diagnosis for both multiple integrated instruments and package equipment.

(3) Use of Microsoft SQL
PRM R3 now uses Microsoft SQL as its standard database, ensuring better compatibility with Microsoft Office tools and supporting a broader range of uses.

(4) PST (Partial Stroke Test) Support
This provides the means to perform critical functions such as partial stroke testing to HART devices.


Data Interchange with FieldMate
History of operations, such as parameter changes, made in FieldMate can be imported to PRM. (FieldMate is a newly released Yokogawa product designed for "Quick and Easy"device configuration)

It has always been Yokogawa's policy to maintain backward compatibility of all of its products with previous versions.  So even through the database has changed from Oracle to SQL server in R3, the installation program automatically converts the database at the time of upgrade.

PRM has become more highly scalable allowing as few as 25 devices for a very attractive entry level price to as many as 20,000 devices that Yokogawa has seen in its very large Fieldbus installations.  As part of its expandability policy, another specification change allows expansions to the system in groups of 1000 device units incrementally.  This allows users to enter with a minimal system and then expand and grow their device capability on their own schedule.

These enhancements are added to the already standard features of maintenance alarm/process alert functions, custom user views, device security, device viewer with built-in trending and an improved graphical user interface supporting both EDDL and FDT/DTM implementations.

PRM is one of Yokogawa's key deliverables of its VigilantPlant™ concept promising asset excellence to visionary plants and creating an environment where plant personnel can See Clearly, Know in Advance, and Act with Agility.
