What's PRM

With PRM and intelligent field devices, operators and maintenance personnel can monitor the condition of plant assets remotely. PRM’s diagnostic functions detect early signs of performance deterioration such as valve sticking and impulse line blocking. By helping curtail excessive preventive maintenance and enabling more predictive and proactive maintenance, PRM opens the way to Asset Predictability.

A way to increase plant lifetime and availability

Unnecessary trips make up 63% of field maintenance work.

Does your maintenance budget breakdown look like this?

Take the walking out of your work.

Online & centralized automation asset management is achieved
with PRM. By monitoring field device health and process
interface conditions online, PRM eliminates unnecessary
maintenance trips and minimizes the need for breakdown and preventive maintenance, thereby reducing OPEX.

Based on open technology

PRM supports the FOUNDATION™ fieldbus, HART, PROFIBUS, and ISA100.11a communicaitons protocols, ensuring an extensive range of devices to choose from. PRM fully embraces an open, rich, and intuitive access to intelligent field devices.

PRM supports FDT/DTM (IEC 62453) and EDDL (IEC 618043). PRM accesses, provides appropriate setting and adjustment environment, and displays field device status.

A variety of connection methods

PRM supports a variety of connection methods:

Via CENTUM VP, CENTUM CS 3000 R3, STARDOM, and ProSafe-RS
Via HART multiplexer and HART modem
Via FOUNDATION fieldbus communication card
Via Ethernet/Profibus converter
Via field wireless integrated gateway (ISA100.11a)

Intelligent and integrated diagnostics information

A more holistic approach to diagnostics

Going beyond individual device diagnostics, PRM integrates and processes both device and process diagnostic data from PST Scheduler, GE Energy’s System1 server, and a host-based advanced diagnostics server to enable a more holistic diagnostics approach.

Device diagnostics and host-based advanced diagnostics are available

Typical applications :

Impulse line blocking diagnostics for differential pressure transmitters
Heat/steam trace diagnostics for a group of pressure transmitters
Electrode adhesion diagnostics for magnetic flowmeters
Gland packing diagnostics for control valves
Valve health monitoring

PRM can monitor the KPIs of devices and units throughout a plant when it is used together with Yokogawa's InsightSuiteAE services. Three specific applications are introduced below:

The ability to perform diagnosis online reduces the need for field inspections, and condition-based maintenance minimizes both planned and unplanned plant downtime. As a result, plant uptime can be maximized.
