Example documentationExample: Automated Collection of Parametric Data During Operation Locate this document in the navigation structure

 

The following process includes steps performed automatically in an external system to collect parametric data during an operation.

Prerequisites

  • You have configured Data Collection and SPC and defined objects described in the Prerequisites section of Example: Collecting Environmental Data for SFC Numbers.

  • You have implemented custom software in the controller of the piece of equipment which will perform the MAKE_WIDGET operation.

  • You have configured the custom software to send the following web service messages to SAP ME upon occurrence of the indicated events:

    Event

    SAP ME Web Service Message

    Arrival of the material at equipment

    • Start (Starts the SFC at operation)

    • LogParametricData (Collects Humidity and Temperature)

    Five minutes after start

    LogParametricData (Collects Humidity and Temperature)

    Ten minutes after start

    LogParametricData (Collects Humidity and Temperature)

    Completion of the operation

    • LogParametricData (Collects Humidity and Temperature)

    • Complete (Completes the SFC at the operation)

    For more information about SAP ME web services, see SAP ME Web Services Guide.

Process

  1. Material for creating the ACME_WIDGET arrives on a conveyor at the equipment identified as MILL_22.

  2. The controller for MILL_22 sends the Start and LogParametericData web service messages to SAP ME.

  3. Five minutes later, the controller for MILL_22 sends the LogParametericData message to SAP ME.

  4. Five minutes later, the controller for MILL_22 sends the LogParametericData message to SAP ME.

  5. MILL_22 completes the milling of the ACME_WIDGET.

  6. The controller for MILL_22 sends the Complete and LogParametericData messages to SAP ME.
