The Device List

The Devices page lists every device in the system. It is where you check what is running, find a specific connection, and act on several devices at once.

Open it from Devices in the navigation. The page header offers two actions: Device Sets, which opens the device set list, and Add Device, which starts the creation flow.

Select any row to open that device's detail page. Right-click a row for its action menu.

Columns

Column	Shows	Hidden by default
Status	A colored status icon. Hover it for the status text, or the current warning or error message	—
ID	The device's numeric identifier	Yes
Name	The device name	—
Protocol	The protocol name, with the sub-type in parentheses where one applies (for example the EtherNet/IP device type). A shield icon appears when the device uses OPC-UA security; hover it for the security mode	—
Connection	The connection string built from the device's protocol settings. Hover a truncated value to see it in full	Yes
Description	The device description	—
Scan Rate	The polling interval	—
Created	When the device was created, relative (hover for the exact timestamp)	Yes
Updated	When the device was last modified, relative (hover for the exact timestamp)	Yes

Status and Name are always visible and cannot be hidden or reordered.

Rows carry state as well: a disabled device is dimmed, and a failed device is tinted red so you can pick it out while scrolling.

Status icon colors

Teal means Running, gray means Stopped, red means Failed. A yellow icon means the device is running but reporting a warning — hover it to read the warning. While a device is starting up or shutting down the icon is gray and the tooltip reads Starting or Stopping.

Searching

The search box above the table matches as you type. Select the magnifier inside the box to choose what it searches:

Mode	Matches
Name & Description	Either field (default)
Name only	The name field
Description only	The description field

Search runs on the server across every device, not just the page you are looking at, and your choice of mode is remembered.

Filtering

Every filterable column has a filter icon in its header. Select it to open the filter, set a value, then choose Done. The icon fills in while that column is filtering, and Clear in the same popover removes it.

Column	Filter	Notes
Status	Multi-select: Running, Stopped, Failed	Matched against live status — see below
Name	Text	Case-insensitive, matches anywhere in the name
Protocol	Single-select	Lists the protocols currently visible in your system
Description	Text	Case-insensitive, matches anywhere in the description
Scan Rate	Minimum/maximum with a unit	See Scan Rate
Created	Date range	Inclusive of both days you pick
Updated	Date range	Inclusive of both days you pick

ID and Connection are display-only and offer no filter.

All filtering happens on the server, so a filter narrows the whole device list and the row count updates with it. Applying or changing a filter returns you to the first page.

Two toolbar controls sit above the table while anything is filtering: a funnel button listing the active filters, where you can remove one at a time or Clear all filters, and a Clear filters button that removes everything at once, search included.

Filtering by Scan Rate

The Scan Rate filter takes a Minimum and a Maximum, each with its own unit — msec, sec, min, hour or day. This lets you type a bound the way the column reads it: to find sub-second devices, set the maximum to 500 msec rather than working out 0.5 seconds.

Changing the unit reinterprets the number you already typed, so 5 min becomes 5 hour. Leave a bound empty to leave that end open.

Filtering by Status

Status is not stored with the rest of a device's configuration — it is written to the live data cache every scan cycle. The Status filter therefore resolves which devices currently match your selection, and then narrows the list to those devices.

Status is a point-in-time match

The matching devices are resolved when you apply the filter. A device that changes state afterwards will not appear or disappear on its own — its icon still updates live, but the filtered set does not. Re-apply the filter or reload the page to refresh it.

When one or more devices are failed, a red N Failed button appears in the toolbar. Select it to filter the list to failed devices immediately. The button hides itself once that filter is applied.

Sorting

Select a column header to sort by it; select it again to reverse the direction, and a third time to clear it. Name, Description, Scan Rate, Created and Updated can be sorted. Status, ID, Protocol and Connection cannot.

The list is sorted by Name, ascending, until you change it. You can sort by one column at a time — choosing a new column replaces the previous sort.

Arranging the Table

Three controls sit to the right of the search box:

Show / hide columns — tick or untick any column. Drag an entry to reorder the columns. Show all restores everything.
Density — cycles through Compact, Comfortable and Spacious row heights.
Full screen — expands the table to fill the window.

At the bottom of the table, choose a page size (10, 20, 25, 50 or 100 rows; 20 by default) and move between pages. The right-hand label shows the rows on screen out of the total, for example 1–20 of 143.

X of Y devices

When a filter or search is active, the bottom-left corner reports X of Y devices — how many match against how many exist in total. It disappears when nothing is filtering, because the two numbers are then the same.

Which columns are shown, plus your sort, filters, search, density and page size, are remembered in your browser, so the list looks the same the next time you open it. Column widths are fixed and cannot be dragged.

Filters persist between visits

Because filters are remembered, a list that looks unexpectedly short may still be filtered from an earlier session. Check for the Clear filters button — it only appears when something is filtering.

Selecting Rows

Tick the checkbox on a row to select it, or the checkbox in the header to select every row on the current page. Selecting rows opens a banner above the table showing the count, with Clear selection.

To act on more than one page of devices, open the Actions menu with nothing selected and choose Select all N devices — this selects every device matching the current filter, not just the visible page. The same menu offers Deselect all N devices while a selection is active.

Bulk Actions

With rows selected, the Actions menu lists the operations that apply to all of them:

Action	Effect
Enable N selected	Starts data collection on every selected device
Disable N selected	Stops data collection. Asks for confirmation first, because collection stops for every tag on those devices
Export config for N devices	Downloads the selected devices as a CSV file
Delete N devices	Permanently deletes the selected devices

Delete opens a confirmation that first checks what depends on those devices, so you can see the impact before committing. If any of the selected devices are still enabled, deleting is blocked until you use the Disable button the confirmation offers.

A progress bar runs across the top of the table while a bulk action is in flight.

Deleting a device deletes its tags

A device's tags belong to it. Deleting the device removes them and stops any expression or model that reads from them. Review the impact listed in the confirmation before you continue.

Row Actions

Right-click a row for the action menu for that device: Enable or Disable, Configuration (opens the device's configuration tab), Open in new tab, Export config, Duplicate, and Delete.

If you right-click a row that is part of a multi-row selection, the menu switches to the bulk actions above and applies to the whole selection.

Editing in the Table

Edit Mode, in the Actions menu, makes the Name and Description cells editable in place. Change as many rows as you like, then save all of them at once; leaving edit mode with unsaved changes asks you to confirm first. A cell that fails validation is marked with an error icon — hover it for the reason.

Row clicks and the right-click menu are suspended while edit mode is active.

Importing and Exporting

The Actions menu also carries Import devices from CSV, and — with nothing selected — Export config for all N devices. See Importing & Exporting Devices for the file format and the import review step.

Stale data indicator

A yellow refresh icon in the toolbar means the page could not refresh: either the device list itself, or the live status feed. What you see is the last good data. Hover the icon for the reason; it clears itself once the connection recovers.

Permissions

Actions you are not permitted to perform stay visible but disabled, with a tooltip naming the missing permission. Enabling and disabling devices, editing, importing and deleting are each gated separately. See Roles & Permissions.
