The device page

Every device has a page that shows whether it is connected and what it is reading. Open it from Connect > Devices by selecting the device's row, or from Open the device at the end of the setup wizard.

The page has three parts, from top to bottom: a summary, a row of tabs, and a Configuration section that is closed until you open it.

Summary

1. Status, next to the device's profile, gateway and type. Above the name is the device's place, from enterprise down to equipment module. Point at the status to see the gateway's full status text.
2. Five figures:
   • Last value: when the gateway last received a value from the device.
   • Tags: how many tags the device has, and whether all of them have good quality.
   • Reads: how many reads succeeded, and how many failed.
   • Response: the device's average response time.
   • Alarms: how many alarms are open for the device.
3. Alarms lists up to five open or acknowledged alarms of this device. Delivery lists the outbound targets that receive its data, each with its state and the time of its last success and last failure.
4. The toolbar. See Actions below.

Status

When a device is not connected, its logs usually say why. For the common causes, see Troubleshoot devices.

Tabs

Live values

1. The tabs: Live values, History, Delivery, Diagnostics and Hierarchy.
2. One row per tag, updated as values arrive. Select a row to open its trend.
3. Quality is Good, Uncertain or Bad. Rows that are not good are highlighted.

The columns are Key (the tag name), Value, Trend (a small chart of the recent values and the change, or Text for a text tag), Quality and Updated. Use the search box to find a tag, and XLSX, XLS or CSV to save the table as a file.

Trend of one tag

Selecting a row opens a panel with the tag's recent values.

1. The time range: 15 min, 1 h, 8 h or 24 h.
2. The chart. Drag the handles under the chart to look at part of the range.
3. Last, Avg, Min and Max for the range.
4. Open in workspace opens the same tag in the Trend Workspace, where you can compare it with other tags.

Under In this range, the panel lists stops, alarms and configuration changes that happened in the range. Stops are shown only for a device that has a machine state tag. Close the panel with the close button or the Escape key.

History

The values the device sent most recently, one row per value: Time, Key, Type, Value and Quality. This is the history of the values, not of changes to the device; for changes, use Audit Trail.

Delivery

The outbound targets that receive this device's data. To add or remove targets for many devices at once, use Targets in the device list. See Outbound targets.

Diagnostics

Counters kept by the gateway for this device, as Key and Value: last communication and last data time, successful and failed operations, average response time, connection errors, the number of values processed, and data quality figures.

Hierarchy

The device's place: Enterprise, Site, Area, Process cell, Equipment module and Group. The place decides where the device appears in the Unified Namespace.

Configuration

Open Configuration at the bottom of the page to see the device's own fields: name, device type, device profile, gateway, Active, attributes and image. Clearing Active stops the gateway from reading the device; the change is saved at once.

To change the connection or the place, use the setup wizard instead: it tests the connection before it saves.
