SUMMARY
Use this guide to understand how factory overview card colours are determined from live sensor data. The card colour reflects the system’s interpretation of whether a production line is running or stopped based on the latest bottleneck sensor state.
WHAT THIS IS
- Factory overview card status is a visual indicator used to represent the current state of a production line. The colour shown on the card is based on live data from the bottleneck sensor.
- Because the system depends on live sensor data, the displayed colour may sometimes reflect an inferred status rather than a confirmed live condition.
WHY IT MATTERS
- Card colours help managers & supervisors quickly identify whether a line is running, stopped, or in an unknown state.
- The system uses sensor data and historical state information to maintain visibility even when a sensor goes offline.
WHEN YOU WOULD USE THIS
- Use this when:
- Reviewing line status in factory overview
- Understanding why a card appears green, red, or white
- Interpreting line behavior during sensor outages
- Explaining why a line status may appear unclear or unchanged
HOW IT WORKS
The card colours are meant to indicate the following:
| Card Colour | Meaning |
|---|---|
| Green | The line is running. |
| Red | The line is stopped. |
| White | The system does not have enough information to determine the line status. |
The factory overview card colour is determined using live data from the bottleneck sensor.
This means that we have to evaluate the status of the sensor to infer what that likely means for the production line.
Below, you can find the logic used to derive the system interpretation and thus the card colour shown:
| Sensor Status | Current / Last Known Condition | System Interpretation | Card Colour |
|---|---|---|---|
| Online | Sensor is counting units (no stop is detected) | The line is running | Green |
| Sensor is not counting units (has detected a stop) | The line is stopped | Red | |
| Offline (for more than 3 minutes) | Last known state was Stopped | The system assumes the line is still stopped | Red |
| Last known state was Running | The system cannot determine whether the line is stopped or if only the sensor disconnected | White | |
| Either | No historical stops whatsoever | The system does not have enough information to determine the line status | White |
Note: Lines using a manual process sensor type are excluded from the offline logic — they will not turn white due to data silence, nor will they remain red based on a last known stopped state, regardless of how long the sensor has been inactive.
KEY TERMS / COMPONENTS
- Factory overview:
- A live production monitoring view that displays line status cards
- A live production monitoring view that displays line status cards
- Bottleneck Sensor:
- The primary sensor used to determine whether the production line is running or stopped
- The primary sensor used to determine whether the production line is running or stopped
- Live Data:
- Real-time sensor information is used to calculate the current machine status
- Real-time sensor information is used to calculate the current machine status
- Offline State:
- A condition where the system is no longer receiving live data from the sensor
- A condition where the system is no longer receiving live data from the sensor
- Inferred Status:
- A status determined from the last known sensor state instead of the current live data
COMMON MISUNDERSTANDINGS
- A white card does not automatically mean the line is new or that the sensor has never detected a stop before.
- “Offline” status is not immediately interpreted as "Stopped" and thus does not always produce a red card.
- White can indicate that the system does not have enough information to determine the current line state.
- White may also appear when no historical stop data exists.
