Machine Connectivity Rate at 99% live connectivity target: a worked example

Push live connectivity target up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when an OT manager or plant manager needs a clean live-connectivity number for the morning meeting board, separate from the slower edge gateway deployment view.

The inputs for this scenario

  • Machines reporting live data in the last polling window: 118 machines (unchanged)
  • Total connectable machines: 125 machines (unchanged)
  • Live connectivity target: 99 % (raised for this scenario; the documented default is 97)

Working through the calculation

  • Applying the documented formula (Live machine connectivity rate = machines reporting ÷ total connectable machines × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 94.4 % for live machine connectivity rate, the number this scenario is built around.
  • At this operating point the engine returns 4.6 points for connectivity gap to target.
  • At this operating point the engine returns 118 count for machines reporting live data.
  • At this operating point the engine returns 125 count for total connectable machines.

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 %.
  • It computes the percentage of connectable machines reporting live in the latest polling window and the point gap to your live connectivity target. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Live machine connectivity rate: 94.4 % (headline result)
  • Connectivity gap to target: 4.6 points
  • Machines reporting live data: 118 count
  • Total connectable machines: 125 count
