QM Sample Generation and Status Update for Quality Specifications

The MES middleware maintenance service periodically checks all entities that can capture QM data to determine if new future samples need to be created. It also checks if existing future samples can be changed to ready samples. It updates the state of previously readied samples, if they are canceled or not complete, once the warning time or expiration time is reached.

The purpose of collecting a sample is to measure the quality of a produced item or a process parameter. Future samples are generated at defined intervals till the end of a shift, or the configured time period in the future. This allows you to view the projected samples of a shift and to measure the quality of samples when they are ready.
