SAP PI can access real time data from OPC Servers of SCADA systems

Data integration of SAP ECC - SAP PI - OPC DA Server (SCADA) is tested........ At last we could able to achieve seamless integration of SCADA system data with SAP ECC using SAP PI module. Following are the lessons learnt from the implementation, 1. OPC Xi SDK form the OPC foundation (www.opcfoundation.org) was very much useful 2. Reading data from OPC Server version OPC DA v2.02 & OPC DA v 3.0 are successfully tested 3. Writing of data back to SCADA system from SAP ECC was a bit challenge due to some missing details in WSDL 4. Performance : we could able to read 3000 process tags at a scan rate of less than 3 sec. 5. Built-in redundancy : Redundancy at OPC Servers of SCADA systems can be utilized and logic built around that in ECC works great. Other future scenarios we need to work on, 1. Utilizing OPC UA based implementation to build more robust communication with OPC XML DA web services 2. OS support for Windows Server platforms (The results from initial trials in Windows 7 are encouraging)
