Hi,

SAP provides the component SAP OPC Data Access (SAP ODA), which is based on the industry standard OLE (Object Linking and Embedding) for Process Control (OPC). It supports the exchange of data between SAP R/3 and process control systems made by other companies

Production control with SAP Production Planning - Process Industry (SAP PP-PI), allows OPC values and events to be integrated into the PI sheet or into the manufacturing cockpit.

Hi,

Go through this

OPC Solution for SAP allows manufacturers to perform back-office analysis and reporting by combining plant control and SAP business data or perform automatic measurement recording, reporting, analysis and notifications to facilitate Reliability Centered Maintenance (RCM), Operating Equipment Effectiveness (OEE) or to enable compliance with the US FDA's 21 CFR Part 11 rule for electronic record keeping. End users can define measurement points based on upon control system tags, and create automatic notifications within SAP from sets of user-filtered process control alarms and events.

Eg:

Many machines operating at a process level in pharmaceuticals companies, for example, stirring or packaging machines, communicate using OPC* (* OPC stands for 'Object Linking and Embedding [OLE> for Process Control' and defines the data exchange within a Microsoft Windows environment). SAP R/3 Enterprise now speaks the lingo too and is able to exchange data via the SAP OPC for Data Access (SAP ODA) interface. SAP ODA is able to read and write values on an OPC data access server. In other words, SAP R/3 can use the OPC server to issue instructions to machines and, when required, react quickly to data it receives from the OPC server, issuing alerts and triggering prompt action via the SAP Alert Management function.

To make the most of these new capabilities, the ERP 'Solid Dosage Forms' scenario in SAP Best Practices for Pharmaceuticals has been extended to include SAP OPC for Data Access and SAP Alert Management. SAP Best Practices for Pharmaceuticals - V1.470 shows companies how to connect an OPC demo server to SAP R/3. This OPC demo server provides process data (for example, critical values), which can be called up in the appropriate phase of the process instruction (PI) sheet. Depending on the severity of the data received, alert messages can be sent in the form of e-mails or text messages to the relevant employee.
