Updated factory monitoring software tool to include a new maintenance and operations support function for displaying statistical information on the status of all devices in the factory



Yokogawa Electric Company announced the release of version R4.01 of its Plant Resource Manager (PRM®) software tool for centralized management of large amounts of data from plant monitoring and control devices as well as manufacturing equipment.

The PRM R4.01, an upgrade to R3.31, has been significantly improved with a new feature that provides the statistical data needed to identify the general condition of devices in a factory. By providing information essential for efficient maintenance and optimal operation, this new version of the PRM will help keep the plant safe.

Manufacturers are constantly looking for ways to improve maintenance efficiency by using software tools such as PRM that can centrally manage large amounts of maintenance information and other types of data, monitoring devices and control from plant to manufacturing equipment, and to quickly identify device failures. that could interfere with the safe operation of the facilities. To better meet these needs, Yokogawa has strengthened the functions of PRM.

With the PRM R3.31, users were able to access the information needed to identify the operating status of individual devices. To address the need for a solution that would provide an overview of the general condition of devices installed in a factory, Yokogawa added a new condition reporting function to R4.01. A new feature that improves maintenance efficiency has also been added.

The main improvement is the display of quantitative status information on all devices in a plant.

A reporting function for key performance indicators (KPIs) on field assets has been added to R4.01. With this function, PRM is able to create and display the following three KPIs: (1) overall device efficiency (ODE), the percentage of time that devices are operating normally (without alarms or events); (2) Time Availability (TA), the percentage of time that devices are communicating normally with the PRM; and (3) performance availability (PA), the percentage of time that devices are operating and communicating normally with the PRM. While the previous version of the PRM only provided information about individual devices, R4.01 has the additional ability to display statistics on the operating status of all devices in a factory. Thus, the PRM R4.01 can help operators detect potential device problems, identify and analyze the causes of failure and determine maintenance priorities. These KPIs can also be viewed when planning a maintenance program.

The update also enables efficient adjustment of device parameters. A template function for setting device parameters has been added to R4.01. Once the parameters are set using this function, the template can be downloaded to multiple devices. This makes it easy to apply settings to devices. When replacing one or more devices, their model can be used on the new device (s) or another model with different parameters that has been prepared in advance can be used. By facilitating the resetting of the parameters, this function allows the immediate start-up and use of the new device (s).

PRM is a software package that centrally manages large amounts of information on the condition and maintenance of plant monitoring and control devices and manufacturing equipment. The PRM supports the main digital field communication protocols (FOUNDATIONMT fieldbus, HART®, ISA100 wirelessMT, and PROFIBUS) and can be used for diagnostic and adjustment devices and software tools from other manufacturers. The PRM includes various maintenance support functions, including online functions for monitoring and diagnosing devices and equipment. PRM can work with FieldMate® device management software for configuration, adjustment and management of field devices. Using FieldMate, current device information stored in the PRM can be verified in the field. For better access to maintenance information, PRM device information is also accessible from any Human Interface Station (HIS) linked to CENTUM® VP integrated production control system.

Industries such as oil and gas, petrochemicals, chemicals, iron and steel, pulp and paper, electric power and wastewater treatment will be the main beneficiaries of improved Plant Resource Manager.
