Event Control
Event Control is the live log for the show. It is built for speed first: capture the issue, keep the stack moving, then add detail as the situation develops.


Start a log
Use the quick log form at the top of Event Control.
- Pick a category.
- Add the caller.
- Write a short title or initial description.
- Add the first action if you have it.
- Add a location description such as
Main stage rightwhen it will help the response. - Select Start Log.
A written location works whether or not Mapping is active. When Mapping is active, you can also select a point or resolve a What3Words address. Nexus keeps the written description and coordinates together; disabling Mapping does not remove either value.
The category is searchable. Type a few letters, pick the best match, and Nexus applies the category defaults such as priority and lead agency where the setup allows it.
Start the log as soon as the control room has enough information to act. A short, accurate first log is better than waiting for a perfect description.
Change event status
The current event status appears in the footer. Its colour shows the status configured for the event.
Select the current status to open the status options. Pick the next status, then use the inline confirmation button to apply it. Nexus changes the footer immediately, sends the change to other connected Event Control users, and creates an automatic log using the category configured for that status.
Work the stack
The stack is the list of logs for the event. It shows log numbers, status, category, priority, title, timing, and visible indicators such as closed state. Select a row to open the detail pane.
When Event Control is first opened, the stack shows a loading state until Nexus has loaded the event logs.
The live connection status tells you whether browser updates are connected. When it is live, updates from other users should appear without a manual refresh.
Nexus periodically refreshes the secure live connection. Live reconnecting may appear briefly during that refresh; Nexus reconnects and catches up automatically.
If an administrator changes Event Control to Read only, the stack remains available but create and edit controls are disabled. If they disable it, Nexus moves you to another available event page. Supported unsent quick-log text is kept as a recoverable draft for that event.
If the live connection is not connected, keep working but be careful before making duplicate logs. Refresh once connectivity is back if the stack looks stale.
Update a log


The detail pane is where the log becomes useful for handover.
- Change the State as work progresses.
- Adjust Priority and Category if the first choice was wrong.
- Set lead and additional agencies so ownership is clear.
- Add comments for actions, decisions, and updates.
- Add attachments when the log needs evidence or a related file.
- Close the log when the issue is finished.
Keep comments factual. Write what changed, who owns the next action, and any decision that someone might need later.
Print a log
Open a log and select the print action in the log header when you need a paper copy or a single-log PDF.
The print page shows the selected log as a clean report with event name, log number, opened time, state, priority, category, agencies, caller, description, location, timeline, attachment list, source details, and the printed timestamp. Select Print, then use your browser's Save as PDF option if you need a PDF copy.
Attachments are listed by filename and file details. The print view does not embed attachment content.
Attachments
Attachments are stored against the log. Where preview generation is enabled, image-style thumbnails may appear after upload processing. Use attachments for evidence, plans, photos, and other supporting files. Do not use them as the only record of an important decision; add a comment as well.
Close a log
Close a log when the situation is done and no one needs to act on it. Closed logs can still be searched and exported.
Nexus keeps closed logs available because they are often needed during handover or after-show review. Hiding them from the live stack is for focus, not deletion.
