Smart Sensor Firmware Workload at 17% setup, verification and retry allowance: a worked example

Push setup, verification and retry allowance up to 17% and the picture changes. This example computes every intermediate figure at that operating point. Use this when planning firmware update campaigns, scheduling configuration labor for a new product release, or estimating the production bottleneck from adding HART/IO-Link programming to your line.

The inputs for this scenario

  • Smart sensors to flash and configure: 100 sensors (unchanged)
  • Average flash and config time per sensor: 5 min / sensor (unchanged)
  • Setup, verification and retry allowance: 17 % (raised for this scenario; the documented default is 15)

Working through the calculation

  • Applying the documented formula (Base programming time = sensors to program x average time per sensor (converted to hours)) to the inputs above produces each figure below.
  • At this operating point the engine returns 23.4 hr for total firmware workload (hours), the number this scenario is built around.
  • At this operating point the engine returns 20 hr for base programming time (hours).
  • At this operating point the engine returns 17 % for setup and retry allowance.
  • At this operating point the engine returns 5 pieces / min for programming rate (sensors/min).

How this compares with the baseline

  • Against the tool's baseline example, where setup, verification and retry allowance sits at 15% and the headline result is 23 hr, this scenario comes in 1.74% above the baseline at 23.4 hr.
  • It computes total firmware programming hours by converting per-sensor flash time across the batch and inflating it by a setup and retry allowance. 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

  • Total firmware workload (hours): 23.4 hr (headline result)
  • Base programming time (hours): 20 hr
  • Setup and retry allowance: 17 %
  • Programming rate (sensors/min): 5 pieces / min
