Statistical data feature enhances plant management software

Through the provision of information that is essential for efficient maintenance and optimum operations, this new PRM release will help to ensure plant safety.

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, from plant monitoring and control devices, to manufacturing equipment, and to quickly identify device failures that could interfere with the safe operation of plants.

To better meet such needs, Yokogawa has reinforced the functions of PRM.

With PRM R3.31, users have been able to access information needed to identify the operating status of individual devices.

To address the need for a solution that would yield insights into the overall condition of the devices installed in a plant, Yokogawa has added a new status reporting function to R4.01. A new function that improves maintenance efficiency has also been added.

A function for the reporting of key performance indicators (KPI) 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 effectiveness (ODE), the percentage of time that devices operate normally (without alarms or events); (2) time availability (TA), the percentage of time that devices communicate normally with PRM; and (3) performance availability (PA), the percentage of time that devices operate and communicate normally with PRM. While the previous PRM release only provided information on individual devices, R4.01 has the added ability to display statistics on the operating status of all the devices in a plant. Thus, PRM R4.01 can help operators detect potential device problems, identify and analyse failure causes, and determine maintenance priorities. These KPIs can also be referred to when planning a maintenance schedule.

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. This makes it easy to apply parameters to devices.

When replacing one or more devices, their template can be used on the new device(s), or another template with different parameters that has been prepared in advance can be used.

By making it easy to reset parameters, this function allows the immediate start up and use of the new device(s).

PRM supports major field digital communication protocols (FOUNDATION fieldbus, HART, ISA100 Wireless, and PROFIBUS) and can be used for devices and diagnosis and adjustment software tools from other manufacturers.

Target markets include oil and gas, petrochemicals, chemicals, iron and steel, pulp and paper, electric power, and wastewater treatment.
