Yokogawa Electric Corp. has introduced its Plant Resource Manager (PRM®) software tool version R3.30. Available from 29 February, version 3.30 is a major upgrade of Yokogawa’s system for the centralised management of large amounts of data from plant monitoring and control devices and manufacturing equipment.
PRM R3.30 upgrades include an improved management function for HART® and enhancements to the navigation function. HART is a field network communications protocol developed by the HART Communication Foundation. The latest version of this protocol is HART7, but PRM R3.30 will also support HART5 and HART6, which are still in wide use.
To optimise plant operations, it is essential to have up-to-date information on device status, and to keep records on all maintenance work that is performed. Such information is useful if operators of control and safety instrumented systems can view it on screen at their human interface stations (HIS).
PRM R3.30 has new features to facilitate the collection of information from field devices for use in decision support activities that help optimise device maintenance and plant operations.
- Quick access to HART device status information: PRM V3.30 can now obtain start-up, stop, failure, and other status information from Yokogawa HART7 compliant devices in almost real time via the N-IO (Network-IO) field input/output (IO) device that was developed for use with the latest version (R4.01) of Yokogawa’s ProSafe®-RS safety instrumented system (released to the market in November 2015). For 3rd-party HART5, 6, and 7 compliant devices, PRM V3.30 can collect information at 1 min. intervals, which represents a ten-fold increase in maximum frequency over previous versions of PRM.
- Intuitive display of device information: Icons indicating the importance of individual devices are now displayed in the device status window of the navigation screen. If a problem occurs somewhere in the plant, operators can use this information and the self-diagnostic information displayed for the devices to make a quick, priority-based response.
- Targeted issuance of alarms: PRM has a maintenance alarm function that issues alarms for display at Yokogawa CENTUM® series integrated production control system HISs. Previously, alarms were issued to all HISs. This latest version of PRM makes it possible to specify which HIS should receive alarms from a specific device, meaning that alarms are only issued to individual operators who are responsible for the specified device.
