Assets
An asset is one piece of equipment your data is about: a DAQ board, a PLC, an instrument. Use assets to see which unit a channel came from, and when.
Where assets come from
A connector says whether its device is equipment. When it is, connecting the device adds an asset on its own.
| The connector… | Asset |
|---|---|
| reads a hardware serial | one per serial — the same unit is recognised when it comes back |
| has no serial (a bus, a PLC on an address) | one per connection |
| reads files, or runs a simulator or engine | none |
You do not add assets by hand. Removing an input does not delete its asset; it becomes Detached and keeps its history.
The Assets screen
Open Assets in Phloem Computer. Search by name, model or serial. Filter by All, Connected, Detached or Needs review.
| Column | Shows |
|---|---|
| Unit | the unit's name and the input that runs it |
| Controls | how many values you can set |
| Readings | how many values it reports |
| Last sample | how long ago it last sent data |
| State | see below |
| State | Means |
|---|---|
| Connected | an input in this project runs it now |
| Detached | nothing runs it now; read-only history |
| Needs review | a different unit appeared where this one was |
| Not arriving | it declares channels, but none is live |
Units are grouped by connector when there is more than one.
A unit's page
Click a unit to open it.
| Section | Shows |
|---|---|
| Surface | its controls first, then its readings, with live values |
| Identity | manufacturer, model and serial, as the unit reported them |
| History | first seen, last bound, and its id |
| Attached channels | channels you attached to it, for example by an import |
| Membership | each channel that belonged to it, and from when to when |
| Delete | removes the asset for good |
Its badge says how it was identified: serial-verified, confirmed by hand
or by connection.
When a channel belongs to a unit
A channel belongs to a unit for a window of time. The window opens when the unit's input starts producing it, or when you attach it. It closes when the input stops, the unit is swapped, or the connector is removed.
Membership lists these windows. A unit's history is read through them. Swap the board behind an input, and the old board keeps its past and the new one starts fresh.
In the console, open a device from Fleets and choose its Assets tab. Each asset lists its open channels and how many past windows it has.
Set a value
Surface lists each control the unit's connector declares, with its range and unit.
- A number: type a value and press Set, or press Enter.
- On or off: use the switch.
A setpoint follows the same safety rules as a test run. It is refused while a trip is latched or when the control is not declared, and the refusal shows as a message. A Detached unit's controls are disabled.
Import a file against an asset
From the command line, import a recording and attach its channels to an existing asset:
phloem asset list
phloem import run-0412.mcap --asset "bench-daq-1"--asset takes an id or an exact name and is required. An import never
creates an asset. Add --driver when more than one connector can read the
file.
Delete asset cannot be undone. The id is retired, and the same unit seen again will not get it back. Recorded data is kept.
