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:

  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 enable 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. Provide data to enhance maintenance and operations
    • Critical equipment information can be checked immediately not only through DCS but also through comprehensive 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.)

  4. Fieldbus diagnosis

1. Diagnosis functions

Prevent trouble through control valve diagnosis

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.

  • Easily make inspection and maintenance plans according to deterioration state and importance
  • Multi-vendor support enables evaluation of the entire plant
  • Simple engineering: Just choose a file to enter settings

Monitoring parameters to leverage device information

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.

  • Easily make inspection and maintenance plans according to deterioration state and importance
  • Prevent sudden equipment failure and reliable operation
  • Simple engineering: Just choose a file to enter settings
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, 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.


3. PST Scheduler

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

  • 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 (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.


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 the amount of time required for the critical plant start-up phase by up to 80%.

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.

Focus on specific plant areas and assets

Device Viewer

PRM device viewer

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.

2. Remote adjustment


DTM/Parameter Manager/ Audit Trail Message

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.


3. Efficient setting of device parameters

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).


4. Asset information management

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.


5. Maintenance alarm

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).

prm actionguide


For operators

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 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.

1. Overview

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.

plant startup


2. Details

More efficient equipment connection checks

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.

conventional connection check

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.

connection check using prm

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.


More efficient I/O loop checks

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.

input loop check

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.

input loop check using prm

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.


output loop check

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.

output loop check using prm

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.


Automatic generation of operations reports means reduced labor and improved quality

  • Reduce man hours

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.

  • Improve report quality

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.

About HIST

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.

About FIST

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.

3. PRM integration

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.

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.


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.
