The PRM software centrally manages large amounts of status and maintenance information from automation and production assets. PRM has various maintenance support functions, including online functions for monitoring and diagnosing devices and equipment.
In this video we show you how PRM software can be useful in preventing the sudden equipment failures that can affect production at a plant.
Damage to or failure of plant equipment can have a significant impact on operation of the plant as a whole. Yokogawa’s Plant Resource Manager (PRM) helps improve your equipment maintenance plans and optimize equipment maintenance costs.
Plant equipment maintenance challenges
Yokogawa’s approach to efficient facility maintenance
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 with based on plant needs
Plant equipment and device malfunctions cause abnormalities and instability to manufacturing workflows, which in turn add to the time it takes to identify the cause of the malfunctions 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 lets you hot-swap equipment with limited impact to operations.
Yokogawa provides solutions across three tiers:
The control valve is one of the most important devices in a plant. Sudden trouble may lead to a drop in production quality or a plant shutdown. The plant has an enormous number of field devices, and many customers struggle with planning and implementing inspection and maintenance plans to maintain the normal functioning of valves.. Control valve diagnostics are useful to help solve this problem. Five diagnosis logic expressions based on field digital technology are included to help detect deterioration of the valve. The diagnosis supports multiple vendors, and can diagnose all valves in the entire plant using in the same diagnosis logic. Inspection and maintenance plans can be drawn up and prioritized according to the diagnosis results.
The spread of field devices with digital communication functions such as HART, PROFIBUS, FOUNDATION™ Fieldbus and wireless advances. These functions enable remote setup of the field devices and detailed monitoring, and contributed to work efficiency. Furthermore, the field devices’ self-diagnosis functions allowed abnormal detection in real time. However, field devices have parameter information that is not being well utilized. Monitoring this information is an effective way to grasp device abnormality trends and respond with preventive maintenance.
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, which is 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.
PRM and PST Scheduler
It is known that partial stroke tests (PST) extend the interval 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 system. 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
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 (SIS) 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 maximizing the plant operation time and reducing the OPEX and TCO.
FieldConnex® Advanced Diagnostic Module (ADM)
In addition to supporting the use of powerful tools such as oscilloscopes and data historians, ADM has a unique commissioning wizard that can reduce the amount of time required for the critical plant start-up phase by up to 80%.
ADM's online monitoring capabilities provide actionable information through PRM's user interface, indicating changes in the fieldbus physical layer before they become critical.
The integration of the FieldConnex ADM interface widens the scope of PRM's asset management capabilities to include the communication status of FOUNDATION™ Fieldbus segments.
End Users and Plant Operators:
PRM has a CMMS interface for Maximo, an enterprise asset management (EAM) system from IBM Software, Inc. Through this interface, Maximo can provide better maintenance operation by acquiring real-time device information from PRM when both systems are connected.
*CMMS: computerized maintenance management system
A single window for managing plant-wide 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 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 is immediately transmitted to 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.
Equipment diagnostic data is shown online in an intuitive format. Equipment data trends can be monitored at a glance.
Plant equipment conditions can be integrally viewed in a list or explorer format. A variety of display formats are available to suit plant needs. Monitor field equipment status online, with icons that facilitate at-a-glance review.
DeviceViewer displays real-time diagnostic and trend data for FOUNDATION™ Fieldbus and HART devices from Yokogawa and other vendors. It features a color-highlighted display of device status and parameters that helps operators grasp the device status at a glance without having to go into the field. DeviceViewer can also run on a CENTUM VP operator station, allowing operators to identify whether a process or a field device is responsible for a failure.
You can set and adjust equipment parameters remotely from the PRM screen. By using the DTM (Device Type Manager) device setting and adjustment tool provided by the vendor, you can adjust devices intuitively and visually using easy-to-understand graphical screens for each model. Also, for devices such as valve positioners that are complicated to adjust, you can make valve adjustments efficiently by calling a dedicated PRM plug-in application. Using these tools reduces device recovery times, and improves your equipment maintenance efficiency.
A template function for the setting of device parameters has been added to R4.01. Once parameters are set using this function, the template can be downloaded to multiple devices. By making it easy to reset parameters, this function allows the immediate start up and use of the new device(s).
Assess past alarm history to craft inspection plans. Saved parameters, as well as those for other equipment, can be reused during inspections and calibration. They can also be sorted by specific equipment, alarms, or other parameters; overlooking alarms or forgetting to change modes after inspection will no longer be an issue.
Synchronization with FieldMate™
FieldMate™ is a versatile device management wizard used to set, adjust, and troubleshoot parameters of field devices. All adjustments and settings made with FieldMate™ can be monitored and managed from a PRM window.
Maintenance alarm functionality takes warnings from equipment and advance diagnostics, adds relevant information, and notifies maintenance personnel. Alarms intended for operators are conveyed via guidance messages from CENTUM HIS (Human Interface Station).
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 are used by maintenance engineers to identify the status of a device. You can 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.
Collaboration with other companies
PRM has an open integration tool for connecting with valve management and device maintenance software from other vendors. This plug-in application (PIA) interface enables these programs to run as PRM clients and communicate with related devices through Yokogawa host systems. Yokogawa provides a PIA interface development kit to software suppliers with a contract. After developing a program with this interface, a supplier sends it to Yokogawa for integration testing.

Integration with GE Energy's System 1®
Field devices and machinery account for 51% of plant maintenance costs.
GE Energy's System 1 is a proven software platform for real-time optimization of equipment and selected processes, condition monitoring, and even diagnostics.
Through integration with System 1, PRM is able to provide a single monitoring window for the diagnosis of turbines, rotating equipment, and reciprocating equipment, in addition to field instrumentation such as pressure transmitters and flowmeters.
Data collected from field equipment is used to generate a field asset KPI report, visualizing possible abnormal trends in equipment and peripheral processes. These reports allow for efficient maintenance tailored to the current and future conditions of equipment.
Display of quantitative status information on all the devices in a plant. A function for the reporting of key performance indicators (Field Asset KPI Report) on field assets has been added to R4.01. These KPIs can also be referred to when planning a maintenance schedule.
Subscribers 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.
This is a solution that automatically checks connections, performs loop checks, generates reports, and performs other functions for field devices that support FOUNDATION fieldbus, HART, and other communication protocols. It reduces labor and increases operating quality in plant startup and maintenance.
Many field devices can be found in plants, and commissioning the plant requires checking whether the devices were installed in the correct location. Checking the location means opening each piece of equipment one by one―a labor-intensive process. But with the PRM commissioning support package(PRM CSP), rather than having to open the equipment, you simply send a command to a device from the PRM CSP and view it on the device’s display. This greatly reduces the time it takes to perform connection checks.
To check whether the device is installed in the right place, you remove the device’s wiring at the site, and then check whether a connection error occurred on the corresponding device on HIS. This requires connecting and disconnecting wiring.
To check the connection, send a command from PRM CSP to the target device to display a specific pattern on the device’s LCD. This lets you confirm whether the device is connected without connecting or disconnecting any wires. You can also check the configured device tag name.
A loop check confirms proper wiring from the field device to the control system, and the quality of signals. I/O loop checks must be performed for reliable plant startup. However, because they involve checking the device status and changing device configurations, the checks need to be performed on site, which requires a lot of man-hours. The PRM CSP can perform I/O loop checks automatically so you don’t have to be on site. This reduces labor and increases operating quality.
Connect a handy terminal to the device and other stuff, change the device’s output value, and check the value change on HIS. Requires configuring the value for the device on site.
Send a command from PRM CSP to change the device’s output value. Next, read the output value from the device on PRM SCP via Exaopc, and confirm its accuracy. This means less on-site work.
Change the device’s output value on HIS, then check the change in the valve’s opening and other properties on the actual instrument on site. Requires checking the actual device on site.
After changing the output value for the device on PRM CSP through HIS, use a PRM CSP command to read the valve’s readback value from the device, and confirm that the value changed to the desired value. This means you don't have to work on site.
Manually organizing descriptions of work performed and formatting it into reports is very labor-intensive. With PRM CSP, you can load test data from range checks and comprehensive loop checks, and automatically create operations reports. This greatly reduces reporting man hours.
Assembling all work contents and data by hand invites errors. The PRM CSP loads data and automatically generates reports in a standard format, which cuts down on reporting errors. Plus, users can flexibly customize the format to create high quality reports that fit the customer’s circumstances.

Yokogawa confirms the interoperability of Yokogawa FOUNDATION™ Fieldbus devices and non-Yokogawa FOUNDATION™ Fieldbus devices with Yokogawa's host system using the HIST (Host Interoperability Support Test) scheme which has been certified by the FOUNDATION™ Fieldbus. The FOUNDATION™ Fieldbus device list shows the devices which have passed the Yokogawa HIST.
FDT/DTM Interoperability Support Test, where FDT stands for Field Device Tool and DTM stands for Device Type Manager, is a test activity to reinforce the interoperability between Yokogawa FDT Frame application and the DTM's of third party field device vendors. DTM and Frame application are being developed independently of one another, with the only prerequisite to comply with given FDT interfaces. The interaction can only work, when compliance with these interfaces can be ensured. Even though the FDT Group itself validates the DTM by a certification process, Yokogawa additionally established an "Interoperability Test Lab" to verify the interoperability of the DTM's with our Frame applications, namely PRM and FieldMate.
PRM has an open integration tool to connect with external applications such as valve management and device maintenance software. This scheme is called the plug-in application (PIA) interface. It enables this software to run on PRM as a client and enables it to communicate with related devices through Yokogawa host systems. Yokogawa provides a PIA development kit for software suppliers with a contract. The suppliers are requested to develop interfacing software and to send it to Yokogawa for integration testing.
Operating under PRM, PST Scheduler remotely executes the PST (partial stroke test) for the emergency shutdown valve. The following list shows the positioners and DTMs which have passed the integration test with PST Scheduler.
PRM supports the following models as HART communication interfaces and has the ability to access parameters and diagnostics information of HART devices via a multiplexer.

To enable central control of the entire plant, all of its subsystems are integrated with Yokogawa's CENTUM VP DCS.
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 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.
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.
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).
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).
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.
Environment and safety are major topics on a global scale in recent times. As symbolized by the effectuation of the Kyoto Protocol, an interest in preserving the environment is growing worldwide, and there is also a tendency to criticize more severely, occurrences of industrial accidents that are accompanied by environmental contamination or which may cause damage, etc., to residents in the surrounding areas.
The FieldMate versatile device management wizard is PC software mainly used for configuring and adjusting field devices. Under the concept of "one tool for all," Yokogawa has been enhancing this software to support a wide range of field devices and field communication protocols.
Asset Excellence (AE) provides a set of solutions for maintaining a plant in good condition at reasonable cost to ensure that it works as a production infrastructure. To reduce maintenance costs without causing a risk to production, it is necessary to change from breakdown maintenance to predictive or preventive maintenance.
Latest field devices have not only various self-diagnosis functions but also process-interface-diagnosis functions such as valve diagnosis of valve positioners and impulse line blockage detection of differential pressure transmitters. The YVP valve positioner can easily perform initial tuning, parameter adjustment, trend monitoring, and valve diagnosis, by using the ValveNavi YVP management software.
Due to emerging competitors from the rapidly growing countries such as India and China and the global economic downturn triggered by the Lehman shock, many companies in the process industries are struggling to survive the severe global competition.
The new CSPC (CNOOC and Shell Petrochemicals Company Limited) petrochemical complex at Daya Bay in southern China is one of the world's largest process industry projects (see box, Figure 1 and Table). It has a control system to match. Process Worldwide spoke to Johan Veerman, principal instrument and process control engineer at CSPC, about the challenges of managing such a huge job.
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.
Yokogawa's web-based DCS Anywhere has simplified commissioning at the Nanhai petrochemicals complex. With a total investment of 4.2 billion US dollars, the Nanhai petrochemicals complex at Daya Bay in Huizhou, China, has attracted a lot of attention because of its sheer scale.
Yokogawa's Raju Seshadri reveals the latest trends in predictive maintenance solutions. We all dream of being able to see into the future, of being able to predict what will happen before it has, and taking decisive action before something negative occurs later.
Asset management systems need to be able to handle more data and present information in better formats if plant managers are to move towards proactive maintenance, says John van der Geer, industrial automation marketing manager at Yokogawa Europe.

- Improving efficiency in plant commissioning and periodic maintenance through the use of field digital technology
Yokogawa Electric Corporation announces the February 29 release of version R3.30 of its Plant Resource Manager (PRM®) software tool for the centralized management of large amounts of data from plant monitoring and control devices and manufacturing equipment. PRM R3.30 is an upgrade to R3.20 and includes an improved management function for HART®* and enhancements to the navigation function. With this new PRM version, Yokogawa aims to capture a larger share of the plant maintenance market.
* A field network communications protocol developed by the HART Communication Foundation. While the latest version of this protocol is HART7, HART5 and 6 are still in wide use.
Manufacturers are constantly looking for ways to improve maintenance efficiency by using software tools like PRM that can centrally manage large amounts of maintenance and other types of data from plant monitoring and control devices and manufacturing equipment. Maintenance personnel use such data to reduce plant downtime and enhance safety by proactively spotting and responding to device failures.
To optimize plant operations, it is essential not only to keep devices in good working order but also to have up-to-date information on device status and maintain records on all maintenance work that is performed. Such information is most useful if operators of control and safety instrumented systems can view it on screen at their human interface stations (HIS).
With such needs in mind, Yokogawa has developed new functions for its PRM tool that facilitate the collection of information from field devices for use in optimizing device maintenance and plant operations.
PRM is a software package that centrally manages large amounts of status and maintenance information from plant monitoring and control devices and manufacturing equipment. With PRM, users can monitor the status of their devices and perform online diagnosis via a network. In addition, PRM centrally manages maintenance information, including device ledgers, in a database, and supplies maintenance information for plant field devices and equipment to maintenance personnel.
