System Variables

What it shows

A live list of the system parameters you choose to watch, each updating on its own as new readings arrive. Use it to keep a few key values in view without opening a full chart, and to change the ones that are yours to change.

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 System Variables, then click Add Widget.

Reading it

Each row is one parameter. A parameter you are allowed to set appears as a live control: a switch, a number box or a dropdown. A parameter the logger reports but does not accept changes for is greyed out and simply displays its latest value.

Who can do what

Anyone who can open the plant can read the values. Writing one needs more than view-only access on that plant: the Installer or Full control level. Below that the logger never sees the change and the app answers "Not authorized: view-only access to this plant".

Settings

Open the tile's settings with the spanner icon.

• Title - name the tile so you know at a glance what it groups.
• User and DDP - two tabs holding a switch per parameter. User lists the variables defined for this site; DDP lists the device data points the logger reports. Switch on only the ones you care about to keep the list short.

Tips

Add more than one System Variables tile, each with its own title, to group related parameters separately.
