The CBUS Event Table displays event information on your CBUS connection.
Both incoming to JMRI and outgoing messages are logged to the table.
While the window is open, it will maintain a list of short on / off events, long on / off events, extended OPC on / off events, on / off accessory response events.
Each event and node combination is unique, the maximum event number is 65,535.
The maximum node number is also 65,535.
The table will always start with no entries, data is not maintained between sessions.
You can open the table automatically by adding it to your JMRI startup action list.
PanelPro > Edit Preferences > Start Up > Add > Perform Action > Open CBUS
Event Table.
Short event codes will be stripped of any node number contained within the event CAN message.
All numeric values decimal.
The filter will highlight any text entered, you can use and spaces in the search
field.
The table will then only show events which contain the search phrase.
Text in the information panel at the bottom of the event table will also be highlighted.
New events added to the table created manually with the create event window at the right of the filter window default to an unknown status, and do not send an event message on creation.
Columns can be selected for display via the top menu bar, these are split into 4 categories.
The column order can be rearranged by dragging the column header.
Change the column sort order by left clicking on the column header.
The event table can loop through the sensor, turnout and light table for any CBUS hardware
addresses ( not internal items ).
Any new events found not already on the table will be added.
Clicking on JMRI columns, then Refresh Columns to populate the JMRI Event On and JMRI Event Off columns.
The address username is displayed, if not present then the hardware address will be displayed.
There could well be multiple items linked to an on or off event, these are all displayed
though you may need to widen the column.
( This will not work with addresses setup to listen to a range of events though these don't
seem to common ).
From the File menu, choose Export to open file save dialog and save the contents of the table in a CSV (comma separated values) text file.
Choose the Print (Preview) menu to create a hard copy of the Event Table.
The events are not currently maintained between sessions.
It is not currently possible to load previous session data into the table from file.
You can import event names and node names from a MERG FCU config file. This is accessed from the JMRI CBUS Node Manager, where the FCU file can be previewed before import.
Received OPC's can be from other JMRI components, or from an external CBUS connection.
All opscodes defined as an accessory event ( with the exception of Fast Clock ) are constant listeners, ie
In this data model, it is assumed that event and node combinations are the unique factor.
Any event OPCs sent with extra data bytes will be logged according to its core event and node combination, irrelevant of extra data bytes.
The extra data is not currently displayed in the table, although likely to be added as a column at some point.
You can view this help page within JMRI by selecting Help > Window Help in the top bar of the MERG Event Table window.
The CBUS Console can help you figure out what events are happening on your layout.
