Machine Data Capture Rate at 68% machine data capture target: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop machine data capture target to 68%, then walk the calculation through step by step. Estimate the share of machines whose data is fully captured to the historian or MES from the count of machines with full capture against the total connected machines, against a capture target.

The inputs for this scenario

  • Machines with all required tags reporting: 58 machines (held at the documented default)
  • Total connected machines in scope: 62 machines (held at the documented default)
  • Machine data capture target: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Machine data capture rate = machines fully reporting ÷ total connected machines × 100.
  • Machine data capture rate works out to 93.55 % at these inputs, and this is the headline figure for the scenario.
  • Capture gap to target works out to -25.55 points at these inputs.
  • Machines fully reporting works out to 58 count at these inputs.
  • Total connected machines works out to 62 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where machine data capture target sits at 95% and the headline result is 93.55 %, this scenario lands almost exactly on the baseline at 93.55 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to machine data capture target, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts a machine as captured only if all required tags report, so it does not credit partial capture; a machine missing one minor tag scores the same as one that is fully dark.

Results at a glance

  • Machine data capture rate: 93.55 % (headline result)
  • Capture gap to target: -25.55 points
  • Machines fully reporting: 58 count
  • Total connected machines: 62 count
