Namespace

The Namespace item shows the plant's data as one tree: site, area, cell and asset, with the signals of each asset under it. Open a branch to go down a level; an open asset shows its path in the tree and every signal with its latest value, unit and how long ago it arrived.

• Search. Type part of an asset, signal, equipment model or unit to narrow the tree to what matches; every branch with a match opens.
• Summary. How many assets and signals are shown and the share that arrived recently.
• Dot. Green when every signal under the branch arrived recently, amber when some did and grey when none did.

The first site opens down to its first asset, also after a filter from another item changes what is shown.

Data fields

Asset and Signal are required: one row per asset and signal. Site, Area and Cell build the levels above the assets; leave one out and the tree skips it. Latest value with Unit, or Text value, is what each signal shows. Bind Seconds since last value with the Min summary.

Settings

• Recent within (s) is how old a signal's last value may be to count as recent.

Where to see it

The Meridian demo plant uses it on Meridian · Data Model Command Center, filtered by the Signal Model item.
