Display

• Row: shows the name, the value and the unit of one variable, with its description below it.
• User variable: shows the value as a switch, a number or a drop-down option. The Ui Comp Type of the variable sets this.
• Device data point: shows the live value as a number.
• Computed variable: shows the live value as a number. If the logger firmware does not send Computed values, the row shows the value from when the tile loaded.

Settings

The spanner icon on the tile opens these settings.

• User: a tab with a switch for each user variable. Set a switch to on to show the variable on the tile.
• DDP: a tab with a switch for each device data point, with the serial number of the device. Set a switch to on to show the data point on the tile.
• Computed: a tab with a switch for each Computed variable. The tab shows only when the logger has Computed variables. Set a switch to on to show the variable on the tile.

Tips

• A user variable row shows the value from when the tile loaded. Reload the page to see a new value.
• To keep groups of variables apart, add one tile for each group.
