Summary

New Features

HPSS Swing Position Alarm

The HPSS Points (FI DCU) asset has a new alarm, the HPSS Swing Position Alarm.
The alarm processes events from the assets LVDT channels (Normal & Reverse Toe, Supp 1 and Supp 2), and will alarm when the last value in a capture trace drifts too far away from the corresponding ORef or CRef channel value.

The new alarm can be found in the missing alarms list for each HPSS asset:

Konux Void Monitoring Data

Konux void monitoring data can now be accessed within Centrix, these will be set up as virtual Loggers within Centrix by the support team as soon as possible.

Train Stop Asset

The new Train Stop asset has two channels, a proceed aspect (DGE) and a motor drive relay (VMR).
The Train Stop asset also includes a bespoke alarm for detecting when the trip arm raises while the proceed aspect is lit (VMR picks while DGE is already picked).

Open

Text Terminal Asset

The Text Terminal asset has a single selectable channel, intended for “SSI Alarms” text channels. Once created, an internal “Decoded SSI Alarms” channel is automatically added to the asset and then every time an event arrives on the SSI Alarms channel it is decoded and saved as an event on the Decoded SSI Alarms channel. This asset will provide a more organised way of viewing text terminal alarm codes whilst also allowing the decoded alarm text to be alarmed more precisely by creating custom Text Channel State alarms for the Decoded SSI Alarms channel.

Improvements to existing features

Hydrive Points

Hydrive Points asset channel's Motor Current and Hydraulic Pressure have been split these into two individually selectable asset channels.
We have also added two new asset channels Hydraulic Pressure Normal and Hydraulic Pressure Reverse to accommodate assets which have been configured with separate Hydraulic Pressure channels for each points swing direction.
All of these changes will improve the configurability of alarms on Hydrive Points asset as each individual capture channel on the asset can now be configured with a corresponding Points Pressure or Points Motor alarm.

Open

Points Playback Graphs

The histogram on the Points Asset playback page used to only show data from capture traces which had the tag “Normal”, the graph now includes from capture traces with any tag other than “Anomaly” or “Maintenance”.
The histogram has also been updated to highlight the data based on how close it is to the alarm threshold. Lastly, each graph with a “T-” time range selector now also includes an option T-90 Days.

Open

Reports

The Points Swing Count and Points Swing Times reports now also support HPSS and Hydrive Points assets.
The SSI Datalink Health report page now includes the connected status bar at the top of each SSI link health heatmap, matching the asset’s playback page.
The AZLM report now includes parameters for maintenance start and end, these can be used to exclude data for a specific part of the day.

Alarm Lists

The Alarm Status list now shows the most recent note on an alarm raise for each alarm and also provides a link to the alarm raise the note belongs to.
A new filter has also been added to both the Alarm Status and Alarm Management lists “Show only unlabeled” which will make the list show only alarms which do not have any alarm labels.
