Tag Table
A dashboard item that lists each device's tags with address, data type, unit, latest value and age, grouped by device, with a search box.
The Tag Table item lists the tags of each device as you would check them while commissioning: the tag, its address and data type as configured, the latest value with its unit and how long ago it arrived. Tags are grouped by device.
- Search. Type part of a device, tag, address, data type or unit to narrow the table.
- Summary. How many devices and tags are shown and how many tags have a recent value.
- Row. A tag without a recent value is greyed; a tag that sent nothing shows no value.
The table shows up to 400 tags; search or select a device in another item to see the rest.
