How to Reduce Machine Downtime: Causes, Costs and Solutions

Peakboard captures machine downtime automatically from PLC, OPC UA and ERP – showing in real time which line is stopped, for how long and why, and revealing recurring patterns before they turn into repeated production losses. That is digital downtime tracking: no manual logging, no data lost between shifts, no fault cause left in the dark.

What is machine downtime?

Machine downtime is any unplanned or planned interruption of machine operation. The distinction matters: planned stoppages for maintenance, changeovers or shift changes are predictable. Unplanned stoppages caused by technical faults, material issues or operator errors hit the plant unprepared – and that is exactly where the greatest improvement potential lies.

What does machine downtime cost?

The cost of an unplanned stoppage is made up of several components: lost output, labour costs for waiting staff, express repair costs and possible penalties for late delivery. In the automotive industry, downtime costs of several tens of thousands of euros per hour are reached. In mid-sized manufacturing companies, typical figures range between €500 and €5,000 per hour of downtime – depending on industry, order situation and machine utilisation.

The most common causes of machine downtime

Studies from the manufacturing industry keep showing the same pattern. The most common causes of unplanned downtime are:

• Technical faults: wear, tool breakage, sensor failure or software errors in the controller
• Material shortages: missing raw parts, tools or consumables
• Operator errors: wrong parameters, wrong tool, missing instruction
• Unplanned maintenance: the result of skipped preventive maintenance
• Set-up and changeover times: often written off as unavoidable, but optimisable with data

What these causes have in common: they are all detectable – provided the right data is available at the right time.

Capturing machine downtime automatically

The first step towards reducing downtime is capturing it completely. As long as downtime is logged by hand – on paper or in Excel – inaccuracies, delays and blind spots creep in. Peakboard connects directly to the machine controller (PLC, OPC UA, MQTT) and records every stoppage automatically: timestamp, duration, machine status. The operator can add the fault reason by touch – in seconds, without leaving the workplace.

The result: a complete, audit-proof downtime history without manual transfer errors. The early shift sees straight away what happened overnight – not only after the handover meeting.

Spotting and eliminating downtime patterns

Individual faults are hard to avoid. Recurring patterns are not. Once Peakboard accumulates downtime data over weeks, connections become visible: faults pile up on line 3 every Monday – because the weekend changeover is not documented cleanly. Scrap rises on machine 7 after every shift change – because a setting is not handed over. These patterns were always there. With Peakboard they become visible.

Tracking downtime on older machines

Not every machine on the shop floor has a modern PLC or a digital interface. Older equipment often cannot be connected directly – but that does not mean it has to stay invisible. Peakboard supports connection via external sensors that measure power consumption or vibration signals and derive the machine status from them. A full digitalisation of the machine park is not necessary – even mixed environments of old and new machines can be brought together in one central overview.

Connection to shop floor management

Downtime tracking is not an isolated tool – it is the data source for the entire shop floor system. The captured downtime data flows directly into the shop floor meeting and makes the discussion fact-based. The digital shift log documents every stoppage with context. And a digital Andon board escalates automatically when a threshold is exceeded – while the machine is still down.
