Meantime Analysis Data Points
Meantime analysis data points are the four values under Equipment / Meantime and Equipment / Line / Meantime. Mean time between failures (MTBF) is runtime in minutes divided by the number of downtime events whose state has Enable Meantime Metrics turned on. Runtime is elapsed time minus planned and unplanned downtime. If none of those events occur, the MTBF cell is left empty. When results are grouped, runtimes and event counts are added first, then divided.
Grouped example: one machine contributes 60 minutes and 2 MTBF events, another contributes 90 minutes and 1 event. The group MTBF is (60 + 90) / (2 + 1) = 50 minutes.
| Data point | Location | Type | Description | Example |
|---|---|---|---|---|
Equipment MTBF | Equipment / Meantime | Number (minutes) | Average runtime between equipment downtime events that count toward MTBF. Only events whose equipment state has Enable Meantime Metrics on are counted. | A filler has 120 minutes of runtime and 4 downtime events, and 2 of those states have Enable Meantime Metrics on. Equipment MTBF is 120 / 2 = 60 minutes. |
Equipment Meantime Metrics Enabled | Equipment / Meantime | Boolean | Whether the current equipment state is included in MTBF. Filter values are True and False. The value comes from the state's Enable Meantime Metrics setting. | The filler is in Jam, and that state has Enable Meantime Metrics checked. The value is True. In Running, with the setting off, the value is False. |
Line MTBF | Equipment / Line / Meantime | Number (minutes) | Average runtime between line downtime events that count toward MTBF. Calculated only for a Line or Cell Group. A line downtime event counts when the equipment state that caused it has Enable Meantime Metrics on. | A line has 180 minutes of runtime and 3 line downtime events caused by states with Enable Meantime Metrics on. Line MTBF is 180 / 3 = 60 minutes. |
Line Meantime Metrics Enabled | Equipment / Line / Meantime | Boolean | Whether the equipment state behind the current line downtime is included in line MTBF. Filter values are True and False. | The line is down for Filler Jam, and that state has Enable Meantime Metrics checked. The value is True. |
