Device Historical Analytics

What it shows

A historical line chart built from the devices on your site. You choose a device model, then the readings (fields) you care about, then which units (serials) to plot, so you can compare devices across the plant or track one closely over time.

Where to find it

Open Dashboard, click the pencil in the dashboard top bar to enter edit mode, click Add New Widget, search the picker for Device Historical Analytics, then click Add Widget.

Reading it

Set the chart up on the Configuration tab of the spanner icon, then read it on a chosen date:

  1. Pick a Device Models entry. Its fields load underneath.
  2. Tick the fields (readings) you want to see.
  3. For each field, choose which devices (serials) to include.

Drag across the chart to select a time range. This brush select gives the minimum, maximum and average over that range. You can also zoom in, and download the plotted data as an Excel workbook named deviceRecord.xlsx.

Settings

The settings icon opens two tabs.

Configuration

  • Title - the name shown on the tile. Starts as Device History.
  • Compare with - Off, Previous day or Same day last week, drawn as dashed lines. It only works on a 1 day period.
  • Device Models, the field ticks, and the device choice per field.

General

  • Refresh Fields - reloads the field list if a device changed. The page reloads.
  • Generic Logger Use - turn on for multi-logger setups.
  • Event marker switches - one per severity, ERROR down to UNKNOWN, choosing which events are drawn.

Add the same field for several serials, then brush-select a busy period to see which unit ran highest.
