Machine Connectivity Rate at 70% live connectivity target: a worked example

This worked example runs the machine connectivity rate numbers for a tougher week than the baseline: 70% live connectivity target instead of the typical 97%. Estimate the share of plant machines that are publishing live data right now from the count of machines actively reporting against the total connectable machines, against the program target.

The inputs for this scenario

  • Machines reporting live data in the last polling window: 118 machines (held at the documented default)
  • Total connectable machines: 125 machines (held at the documented default)
  • Live connectivity target: 70 % (the input this scenario stresses; the baseline uses 97)

Working through the calculation

  • The calculation starts from the formula this tool documents: Live machine connectivity rate = machines reporting ÷ total connectable machines × 100.
  • Live machine connectivity rate works out to 94.4 % at these inputs, and this is the headline figure for the scenario.
  • Connectivity gap to target works out to -24.4 points at these inputs.
  • Machines reporting live data works out to 118 count at these inputs.
  • Total connectable machines works out to 125 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where live connectivity target sits at 97% and the headline result is 94.4 %, this scenario lands almost exactly on the baseline at 94.4 %.
  • Use it as a daily or shift operational check on data-collection health, not just during initial rollout. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Live machine connectivity rate: 94.4 % (headline result)
  • Connectivity gap to target: -24.4 points
  • Machines reporting live data: 118 count
  • Total connectable machines: 125 count

Run it with your numbers

  • To rerun this with your own numbers, open the live Machine Connectivity Rate calculator, set live connectivity target to your actual value, and adjust the remaining inputs to match your operation.
