Track Circuit Occupations
Track Circuit Occupations shown on Threshold Graphs
Centrix stores analogue events for the electric current for DC Track Circuits and average current for Audio Frequency Track Circuits.
Each of these occupations (clear - occupied - clear / high current - low current - high current) can be considered as an occupation event.
If analogue channels are associated to the relevant Track Circuit Assets, then Centrix can now analyse the incoming data to try and locate these occupation events.
This allows Centrix to show these occupations graphically on the Alarm Thresholds graph that already exists on the asset and alarm raise pages.
The 'Typical Behaviour' line shows the average clear and occupied values over the last 30 days. Overlayed on top of this is a specific occupation event.
If an asset / alarm raise has no track circuit occupations (e.g. alarm associated with a channel not an asset), then this typical behaviour graph reverts to its old behaviour where it shows only the typical minimum and maximum values and plots them against the alarm thresholds. The dashed line shows the most recent value.
Creating occupation events will allow Centrix to show high level information about Track Circuit Assets such as the number of occupations in the last time period (week / month / year etc.) and how many alarms have been raised as a fraction of total occupations in the last time period. They will also be able to be used to create track circuit alarms on these analogue channels.
Note: a track circuit flick will be considered as an individual occupation. Therefore, an occupation with multiple flicks will actually be shown as multiple occupations. In the future this will make setting up Track Circuit Flick alarms against these analogue channels very straightforward.

Virtual Channel Timing Report
The Virtual Channel Timing Report is a new report designed to give users the ability to quickly look at the spread of recent Virtual Channels which use timing expressions.
This report is essentially an enhanced and opinionated Analogue Histogram Report. It has less options for the user to select on creation and the time range defaults to a year.
As well as a histogram showing the spread of the data, the 10 most recent values and the 10 most recent alarm raises are shown.
The report also allows the user to download the raw data as a csv or excel file. These downloads contain all of the values and all of the alarm raises in the time range.
Alarms linked to assets
As of Release 89 , the following alarms have now been linked to assets:
Points
Points Flick
Possible SPAD
Signal Reversion
Track Circuit Flick
As of this release, the following alarms have now also been linked to assets:
Track Circuit
Track Circuit (Audio Frequency)
Points Flick (Bulk alarm creation - can select multiple assets to create multiple alarms)
To bulk create Points Flick alarms, you have to select multiple points assets. It is not possible to bulk create points flick alarms by creating a site (or sites) and multiple channels.
New Channels page updates
Creating Channels
To create a new channel in Centrix click the "Create New Channel" button, on the Channels list.
The new channel page requires a name, site and channel type to be input.
When creating an analogue channel, units can be selected or input.
For both digital and analogue channels, the channel can be a virtual channel.
To make a new virtual channel, select "Yes" on the "Virtual Channel" toggle and add a virtual channel expression (see creating and editing virtual channels).
Creating and editing Virtual Channels
Virtual Channel Expression Logic
This section describes the workflow for creating or editing a Virtual Channel, for a full explanation of virtual channel expression logic see https://confluence.mpec.co.uk/x/gIFJ
Virtual channel expressions can now be created/edited on the new html channels page.
The virtual channel expression can be edited by typing in the text input or by selecting an operator, analogue input or digital input from one of the selectors.
Selecting an operator, analogue input or digital input will insert it into the virtual channel expression at the current cursor position.
