    Plant Resource Manager (PRM)

    The PRM software centrally manages large amounts of status and maintenance information from automation assets as well as production assets. PRM has various maintenance support functions, including online functions for monitoring and diagnosing devices and equipment.

    What is the proper plant asset management (PAM)?

    Yokogawa's PRM leads to the resolving of PAM issues throughout the plant life cycle.

    PRM Overview

    Why it is important to have a proper asset management regime in place for reliable, efficient,and profitable plant operations

    Damage or failure of plant equipment can have a significant impact on operation of the plant as a whole. Yokogawa’s Plant Resource Manager(PRM) allows optimization and improves the fidelity of maintenance processes with justifying costs.

    Plant equipment maintenance challenges

    • Complexity of vast fleet of equipment
    • Lack of maintenance resources
    • Depletion of institutional knowledge

    Yokogawa’s approach to efficient facility maintenance

    • Centrally manage and visualize plant equipment data
    • Achieve cost savings through improved maintenance efficiency
    Plant image

    Yokogawa offers equipment maintenance solutions that provide both reliability and efficiency

    Yokogawa is a trusted provider of systems that keep the plant online, as well as maintenance solutions that allow operations to stay online while achieving reliability and efficiency gains.

    Yokogawa streamlines plant management across three levels!

    Select which tier to start using based on plant needs

    Malfunctions of plant equipment and devices cause abnormalities and instability to manufacturing workflows, and in turn add to the time it takes to identify the cause and restore the system. As a result, overall production efficiency goes down. Anticipating equipment malfunctions before they occur and monitoring plant processes for prevention of failures and hot-swapping of equipment with limited impact to operations.

    Yokogawa provides solutions across three tiers:

    1. Visualize and remotely configure equipment status
      • Device templating allows for efficiently propagating shared parameters across multiple devices
      • Device Type Manager (DTM) and other specialized calibrating tools enables equipment to be brought online quickly
      • More efficient equipment replacement by tracking and comparing parameter logs
      • Reduce man-hours by checking and configuring device parameters remotely
    2. Monitor equipment and device performance
      • Device patrolling ensures periodic polling of status data for efficient assessment of equipment conditions
      • Versatile diagnostic algorithms allow for measuring valves from multiple vendors
      • Periodic and automatic equipment status reports (field asset KPI reports); visualize conditions and comprehensively assess the health of the plant
    3. Providing data to enhance maintenance and operations
      • Critical equipment information can be checked immediately via not only DCS but also entire ICSS (*1) integration for rapid response to problems
      • Loop diagnostics allow for improving control valve performance and maintaining high productivity
      • Work order efficiency is achieved by integrating with higher level systems (ERP/CMMS (*2), etc.)
        *1) ICSS : Integrated Control and Safety System (incl. DCS, SIS, and other subsystems)
        *2) ERP : Enterprise Resource Planning, CMMS: Computerized Maintenance Management System

    2. Predictive Maintenance of Pump Cavitation (Cavitation Detection System)
    3. PST scheduler
    4. Fieldbus diagnosis

    1. Diagnosis functions

    Prevent trouble by control valve diagnosis

    The control valve is one of the device which are the most important in a plant. Sudden trouble may lead to a drop of the production quality and a plant stop. There are the field devices of enormous numbers to the plant and has a hard time for check maintenance plan making, enforcement for many customers to keep the normal function of the valve. A control valve diagnostics is useful for a help of the solution to this problem. Five diagnosis logics based on the field digital technology are equipped with for this diagnosis and contribute to the deterioration state detection of the valve. The diagnosis supports multi-vender and can diagnose a valve of the whole plant in the same diagnosis logic. Check maintenance plan making in consideration of priority depending on a diagnosis result is possible.

    • The planning of the check maintenance plan making on a deterioration state and importance is easy
    • The evaluation that covered the whole plant by multi-vender correspondence is possible
    • The simple engineering that the setting only chooses the file of the valve

    Support inflection of the device information by parameter monitoring

    The spread of field devices with the digital communication facility such as HART, PROFIBUS, FOUNDATION™ Fieldbus and Wireless advances. In this way, setting work from the remote for the field device and detailed monitoring are enabled and contribute to work efficiency. Furthermore, the self-diagnosis function that the field device had allowed the abnormal detection in the real time. However, as for the inflection of the parameter information that the field device has, it cannot be said that enough utilization is done yet. The monitoring of the parameter information is effective for the grasp of the tendency to devices abnormality and can make use for the preventive maintenance of the devices.

    • Check maintenance plan making depending on a deterioration state and importance is easy
    • Prevention of the idiopathic trouble of the devices and the stable operation
    • The simple engineering that the setting only chooses the file of the devices
    Control Loop Diagnostics

    2. Predictive Maintenance of Pump Cavitation (Cavitation Detection System)

    Providing data that will optimize maintenance and operations

    Early detection of equipment abnormalities allows for efficient plant maintenance

    Yokogawa’s cavitation detection system does not rely on detection by vibration or pings, the traditional technique used to detect cavitation after it has already progressed. Instead, our solution detects fluid pressure differentials caused by early cavitation, allowing for quantitatively determining the extent of possible cavitation. Early detection of cavitation provides plant operators time to take proper countermeasures to prevent damage to pipes


    3. PST Scheduler

    PRM and PST Schedule

    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.

    Perform automatic and semi-automatic PST’s of multiple valves per preconfigured settings and log the results. A PST allows larger lengths of time between each FST, which normally requires taking a plant offline.

    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
    PST scheduler

    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.


    4. Fieldbus diagnosis

    FieldConnex® Advanced Diagnostic Module (ADM)

    system overviewIn addition to supporting the use of powerful tools such as oscilloscopes and data historians, ADM has a unique commissioning wizard that can reduce up to 80% the amount of time required for the critical plant start-up phase.

    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).

    Predictive maintenance allows to schedule plant maintenance before a failure occurs only when it is necessary, greatly reducing unnecessary inspection and improving productivity. Yokogawa's Asset Excellence initiative helps its customers make their plant asset condition predictable and performance sustainable.



    Decades of operation, modernization and expansion have left many chemical plants with a somewhat haphazard automation mix of different controls, process control systems, remote I/Os and field devices. The various components may use different communication protocols such as HART, PROFIBUS or FOUNDATION Fieldbus, and are often based on different device integration technologies. 


    Combining smart instruments, analyzers and valves with a modern asset management system can provide faster response to incidents, enable proactive maintenance, and reduce downtime.
