Use Spec Configuration to Collect Automatic Data

  • Last UpdatedMar 19, 2016
  • 3 minute read

When a characteristic is configured to Use Configuration To Collect Automatic Data, the timer resets and starts each time a new ready sample is received from the MES database. The start time for the delay timer is the time it receives a new sample in the SRO.

When the time evaluates to True, the SRO collects the result data and the MES result attributes data that are currently available in the SRO, and logs them in the MES database.

The table below indicates how result data from the SRO is captured and logged in the MES database when the SRO is configured to collect a maximum of 4 readings at a time. The characteristic ‘Width’ is linked to different specifications with different time intervals in the MES database.
