# State Timeline

> A dashboard item with one lane per line or machine and a coloured band for each state, such as running, waiting, down or changeover.

The **State Timeline**  shows what each line or machine was doing
across a shift or a longer period. Use it to find when a line stopped, for how long and why, including the short stops
that never reach a logbook.

- **Lanes.** One lane per value of **Line or machine**, with a band for each period in a state.
- **Colours.** Running, waiting (starved or blocked), down (a fault), changeover, planned stop (maintenance,
  cleaning, breaks) and off each have their own colour.
- **Legend.** Above the lanes, with the total time of each state. Select a state in the legend to hide or show it,
  for example to leave only the stops.
- **Tooltip.** Point at a band to read its state, its reason, its start, its end and its length.

Zoom in time with the mouse wheel, a pinch or the slider under the lanes. Select a band to filter the other items of
the dashboard by its lane. On a narrow item the lane names sit above the lanes.

## Data fields

**Line or machine**, **State** and **Start** are required, with **End** or **Duration**: one row per period. When a
row has no end, the item adds the duration to its start. The **State** value sets the
colour. The item reads common English state words, in any case: for example `Running`, `Starved`, `Blocked`, `Fault`,
`Changeover`, `Planned maintenance`, `Cleaning` and `Off`. A number is read as a Proxus machine-state code (0 off,
1 running, 2 starved, 3 blocked, 4 fault, 5 changeover, 6 planned maintenance, 7 cleaning). **Reason** is shown in the
tooltip.

## Settings

**Show running share** writes each lane's running time as a share of its time, beside the lane name. A narrow item
leaves it out.

## Where to see it

The Meridian demo plant uses it on **Meridian · Line Performance** and **Meridian · OEE Command Center**, and for the
time in each vibration zone on **Meridian · Condition Monitoring Command Center**.
