Learn how to integrate SAP Manufacturing Integration and Intelligence (SAP MII) with manufacturing automation systems using SAP Plant Connectivity (PCo) by query and notification agents for real-time process visibility in manufacturing operations. Understand the use cases of process event management by connecting to different types of manufacturing automation source systems and SAP MII as the destination system.
Learning Objectives

Reading this article, you will learn how to:

  • Integrate manufacturing automation control systems with SAP Manufacturing Integration and Intelligence (SAP MII) in real time
  • Get real-time event notifications from manufacturing automation control systems for quick actions on process deviations
  • Enable real-time visibility on process data from manufacturing operations
Key Concept

SAP Plant Connectivity (PCo) is an add-on component to SAP Manufacturing Integration and Intelligence (SAP MII) that provides bidirectional connectivity with a manufacturing automation control system such as supervisory control and data acquisition (SCADA), distributed control system (DCS), or Plant Data Historian.

A manufacturing shop floor consists of numerous machines and devices that continuously generate a huge amount of process data. It is critical to ensure that the data is analyzed and acted upon in real time to ensure smooth operations and quick decisions in case of deviations.

Connecting manufacturing execution applications and enterprise planning systems to manufacturing automation systems, such as supervisory control and data acquisition (SCADA), Plant Data Historian, or the laboratory information management system (LIMS), is important and frequently needed by shop floor users to monitor and analyze the information collected from the manufacturing processes and machines.

I show you how to integrate SAP MII with manufacturing automation systems using notification agents for getting notifications on changes of values in the source system, and using PCo query or tag query to query data from the source system. I also discuss some use cases of event management by connecting PCo to different types of manufacturing automation source systems and destinations such as SAP MII. With SAP MII and  PCo real-time integration with manufacturing automation systems can be easily achieved, even though the underlying systems may provide different types of connection protocols, such as object linking and embedding (OLE) for Process Control (OPC), OLE for Database (OLE DB), Open Database Connectivity (OBDC), and File System, as well as proprietary connectors to OSISoft PI, Aspentech InfoPlus 21, and GE Fanuc iHistorian. While SAP PCo acts as the connection adapter for the automation systems, SAP MII provides the business logic to manage the data and incorporate business rules as required to derive real-time intelligence on the process data.

Note
Prerequisites for being able to go through the steps in this article are knowledge of shop floor automation systems and SAP MII.
