Machine History
A machine-specific historical analysis page for reviewing trends across a date range.
Overview
Access: Any role with access to this machine. Roles and access.
Show longer-term machine behavior across many days instead of a single live day.
Users usually reach it from the Machine Details page.

What You Can See
- Date-range controls.
- KPI averages, trend charts, and timeline reason summaries.
- Historical views that make recurring patterns easier to spot.
Machine History now counts time since the last state change for 1W, 1M, 3M or any chosen range, as does the Timeline report over several days. Days spent idle or off now show that time instead of almost nothing; today counts up to now.
When the sensor sends no signal for more than 20 minutes, the last state counts only until the last signal. For a sensor powered by the machine, that silent time counts as Off.
What You Can Do
- Change the review period.
- Toggle whether zero-output days count in the analysis.
- Compare how the machine performed over time.
Review Worked Orders
The Orders section shows work booked on this machine during the selected period. The chart opens with the whole period in view. Its upper bars show worked stretches: Production uses a white bar and Preparation a white bar with a blue border. A step can have several bars. The row underneath shows machine states on the same time axis. The legend sits above the chart.
Use Zoom in, Zoom out, or hold Ctrl and scroll to zoom. Scroll sideways or drag empty chart space to move through time. Whole period returns to the full view. Zooming out and fitting are unavailable when the whole period already fits.
The worked-time total covers the displayed period. The order count counts each order once, even when it has several steps. For longer selections, the orders chart and its state row show only the last 3 months. The notice reads Orders are shown for the last 3 months of the selected period.
Select a Step and Follow Its Order
A part passed on shows Handed over in the list, card details, and selected step. Its grey badge shows where the rest went and how many good parts were made here. Incoming work shows where it came from. Recorded work stays in this machine's history; the label does not mean the whole step is finished. See handover details.
Nothing is selected when you open the section or change the period. Click a bar to highlight that step's stretches and find it in the list below. You can also click a list row. The list shows running work first, then recent work, grouped by day.
The details panel appears beside the list on wide screens and below it on smaller screens. It shows the selected step's status, actual times, planned window, and quantities. Operations of this order (previously Steps of this order) shows the route, including previous and next steps. Steps marked On another machine are visible but cannot be selected here. Under Order, check Delivery date, status, and how many steps are done.
Choose Open order to open the full order in a new tab if you have access. Selecting a row only selects the step; it does not open the order. Close the panel or click empty chart space to clear the selection. Reviewing history changes no bookings or plans.
Compare Booked Time with Machine States
Booked time splits the step's recorded time into Preparation and Production. Machine states shows what the machine actually did during those bookings, including idle, off, or unknown time. Use each section's information icon for its explanation. For example, a step booked as production can include time when the machine was idle.
The step's details cover all its recorded work on this machine, including work outside the selected period. Its times, produced quantity, and analysis totals can therefore exceed what the chart shows. Hover over a bar to see that stretch's Type, Start, End, Duration, and machine states first, followed by the step's details. The information icon at the end of a list row shows the step without selecting it.
Hover over the state row to read the state, its times, duration, and any recorded reason. Accessibility patterns in your profile also applies to this row and its legend: dots for idle and diagonal lines for off.
Empty Orders or Missing States
Without booked work, the section keeps its space and shows No orders were worked on this machine in this period. in a centred message instead of a chart. This does not prove the machine was off; it means no order work was booked in that period.
Missing state information is separate: the state row can show No machine state data in this period. and the selected step can show No machine state data for this operation. Follow Review Machine History.
All Day or Planned Shift Time?
For machines using scheduled shifts, All Day uses 24 hours and Planned uses scheduled shift time. Match this mode, the date range, and the zero-output-day choice when comparing averages. Work centers have no sensor-based analytics.
AVL means Availability; PRO means Performance. Watchmen's time-based definitions differ from textbook OEE. Use calculations to interpret them before comparing periods.
Understand Active Shifts
Active shift identifies a machine whose shifts follow machine activity. A shift starts at idle, production, or preparation and ends according to the machine's shift settings. Its assigned shift group is not used. See Machine Configuration.
Waiting for the next active shift or waiting for machine start means the next shift has not started yet. It starts automatically when the machine begins idle, production, or preparation. Until then, planned shifts from the assigned shift group are shown. This display does not switch off active shifts.
Select the shifts you want to review; the charts use the selected shifts. Open the shift details to check their times. Choose Whole day to review the full day. Shift energy totals follow the company's local shift times. Follow Review Machine History.
Read Automatically Labelled Breaks
If an administrator enables automatic break labels, finished idle or off downtime can receive the reason of a scheduled shift break. A person's choice takes priority. Earlier completed downtime is not relabelled when the setting is turned on.
With Label only the break (recommended), a longer downtime can appear as several parts: the break with its tolerance, plus the time before or after it. Each part counts as one downtime in counts and averages by reason. The remaining parts use the rules for their own length. Total time in each machine state stays the same. With Label the whole downtime, a long breakdown can appear entirely under the break's reason.
Read Downtime Reason Codes
Downtime chart labels include a reason's code when one is set. Short labels may be cut off; hover over a bar or pie slice to read the full name, code, and category. Categories help identify reasons; the charts still group by reason.
See downtime reason settings for how administrators maintain these labels.

Common Outcomes
- Users confirm whether a problem is isolated or recurring.
Limits and Empty States
- Very short ranges reduce the value of a history page.
