What’s PRM(Plant Resource Manager)?


Plant Resource Manager (PRM) is a plant asset management (PAM) software tool that works with production control systems such as CENTUM, STARDOM, and ProSafe-RS. With PRM and intelligent field devices, operators and maintenance personnel can monitor the condition of plant assets remotely. PRM detects early signs of performance deterioration such as valve.



Based on open technology

PRM supports the FOUNDATION™ fieldbus, HART, PROFIBUS, and ISA100.11a communications protocols, ensuring an extensive range of devices to choose from. PRM fully embraces an open, rich, and intuitive access to intelligent field devices.

PRM supports FDT/DTM (IEC 62453) and EDDL (IEC 618043). PRM accesses, provides appropriate setting and adjustment environment, and displays field device status.


A single window for managing plant-wide assets

Focus on specific plant areas and assets

The device navigator displays the status of plant-wide assets with a Windows Explorer-like interface. Flexible navigation mechanisms enable maintenance personnel to quickly identify areas of the plant that require online diagnosis.Intuitive status icons for the field devices change color depending on the diagnostic conditions. Maintenance personnel can easily focus on specific plant areas and assets that require attention.

The right information to the right people at the right time

Maintenance information immediately notifies the right people (operators and/or maintenance personnel), depending on the type and criticality of the diagnostic data analysis. Necessary actions can be taken at the right time, maximizing productivity.

For operators

The DeviceViewer window displays

The Operator Guide Message generated by a predictive maintenance alarm gives operators enough time to manage process changes when an asset fails. Operators can check the device diagnostics information by clicking the Operator Guide Message to launch DeviceViewer.

For maintenance personnel


PRM action guidance messages help maintenance personnel determine what actions are needed based on alarm details and probable causes. This allows field maintenance personnel to make the most efficient and effective use of their time. The DeviceViewer window displays real-time diagnostic parameters
and trend data for field devices.


Maintenance Marks

Maintenance marks

Maintenance marks are used by maintenance engineers to identify the status of a device. It is possible to assign a maintenance mark to each device. Using these marks, maintenance engineers can set and check the work status of devices. Maintenance marks can also be linked with CENTUM's operation marks so that maintenance engineers and operators can share the same information and coordinate their work.


Easy and flexible access to historical data

PRM's historical records automatically store information on the who, when, why, and what of the changes that are made to field assets, along with all alarms, diagnosis results, and maintenance work records. The historical records can be filtered and sorted for quick analysis.

Device report function

device reportSubscribers to Yokogawa's InsightSuiteAE services can use PRM to generate daily, weekly, monthly, and annual field asset KPI reports from the alarm and event messages that are saved for FOUNDATION fieldbus and HART devices. A KPI report provides an overview of device conditions and helps users prioritize their maintenance activities.

It is known that partial stroke tests (PST) extends the interval period between full stroke tests (FST) for emergency shutdown valves and help to reduce maintenance costs. PST Scheduler brings precision, efficiency, and integration to the PST process. PST Scheduler can schedule an automatic, semi-automatic, or manual PST and automatically record test results for safety valves connected either to a Yokogawa ProSafe-RS or another safety instrumented systems. PST Scheduler works with safety valves from the four leading vendors.

pst scheduler display

PRM and PST Schedule

Operating under PRM, PST Scheduler remotely executes the PST provided by the safety valve vendor, and records the results. Testing is efficient and well planned and results are shown on a single screen without any additional hardware or software.  Only Yokogawa's PRM and PST Scheduler support safety valves from multiple vendors.


Features of PST Scheduler

Schedule: Week, Month, Year, On demand
Mode: Manual, Semi-automatic, Automatic
Execution: Serial, Parallel
Operation: Execute, Pause, Resume, Skip
Recording: PST results

Maximize safety system performance
Yokogawa's ProSafe-RS safety instrumented system is SIL3 certified even in a single modular configuration. Execution of PSTs on a fixed schedule is key to ensuring that a safety system will function correctly in an emergency. The combination of ProSafe-RS and PRM with PST Scheduler not only simplifies the management of safety devices, it maximizes safety system performance. In addition, no additional wiring or hardware such as a multiplexer is needed to manage safety devices.

Optimal flexibility in valve selection
The Vigilant Integration Partners (VIP) program is an open, non-exclusive, standard-based, and interoperability-driven initiative that enables users of Yokogawa's ProSafe-RS Safety Instrumented System and PRM asset management system to use best-in-class field devices from Dresser Masoneilan, Flowserve Corporation, Metso, and SAMSON AG.


What is a partial stroke test (PST)?

A partial stroke test (PST) partially opens and closes emergency shutdown (ESD) valves while the plant is running. Safety standards, such as IEC61508, IEC61511, or ANSI/ISA-84.00.01, require full stroke tests (FST) for those ESD valves to be conducted at certain intervals depending on the safety integrity levels (SIL) to make certain that they are functional in case of emergency. FST requires those shutdown valves to fully open and close, and it can only be done while the plant is shut down for maintenance. However, by conducting PSTs, it is possible to extend the intervals of the FSTs, thus the plant operation time can be maximized, which means the OPEX and TCO are reduced.

PLUG-IN Applications


DeviceViewer Parameter window / DeviceViewer Trend window

DeviceViewer displays real-time diagnostic and trend data for FOUNDATION™ fieldbus and HART devices from Yokogawa and other vendors.

Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.


In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.

Yokogawa Technical Report

Yokogawa Electric Corporation promotes the standardization of FOUNDATION™ fieldbus as the communication foundation supporting Asset Excellence for VigilantPlant, which is an approach aimed at the advancement of plant instruments and equipment. With the recent dramatic advancement of fieldbus technologies, information processing technologies, and network speed, it has become possible to process various kinds of information inside the field sensors and transmit the results to the distributed control system (DCS) and host computer.

Yokogawa Technical Report

In 2005, Yokogawa announced "VigilantPlant" as a concept to ward the realization of a type of plant operation that is considered ideal by our customers.


Intelligent field instruments and process analyzers accumulate diverse field information including process values and diagnostic results. This data needs to be sent to upper systems such as distributed control systems (DCS) via digital communications such as FOUNDATION Fieldbus and analyzer buses, or hybrid communications such as HART and Brain, and visualized to enable the customer to utilize them for plant operations and maintenance.


More than ten years have passed since the first digitized field devices were introduced. These support either a hybrid communication protocol such as HART or a full digital communication protocol such as FOUNDATION Fieldbus.


As field instrumentation devices become increasingly digitized and computerized, interactive and remote access to a large quantity of field information becomes possible. This will increase the efficiency of plant equipment maintenance by reducing labor requirements in field patrol work for example. 

Yokogawa Technical Report

There has been increasing demand for cost reductions and lower-priced products in the manufacturing industry, and maintaining cost competitiveness and achieving optimum costs have become necessary for the survival of manufacturers. This calls for minimizing TCO (Total Cost of Ownership) over the whole life cycle of plants and maximizing TVO (Total Value of Ownership).

Yokogawa Technical Report

Process automation involves both operation and maintenance. Plant operation and monitoring are mainly conducted by a control system such as CENTUM, while equipment maintenance is handled by Plant Asset Management (PAM) such as Plant Resource Manager (PRM).

Yokogawa Technical Report

As compared to Distributed Control Systems (DCS) such as CENTUM VP that monitors the operations of the overall plant, PRM is a type of Plant Asset Management (PAM) software package that primarily focuses on the maintenance of devices and instruments.
