For a better experience, please enable JavaScript in your browser before proceeding.The whole point of OPC is that in principle it doesnt matter what sort of SCADA DCS PLC system you have.
If you are seriously interested in PI or an existing customer then talk to OSI about getting a demo on your equipment. OPC Communicate uses a Client-Server architecture. Scada system is an OPC server and OSI-PI is an OPC server then these two wont be able to talk to each others without the help of a client (or a double headed client). ![]() For real-time systems where the SCADA has no historian we typically use the PI OPC-DA Client, whereas if an historian is present with the SCADA system we will use PI OPC-HDA client. Typically your SCADA system will have an OPC server converting your native PLC protocols to OPC. In the case of Rockwell the OPC server would typically be a flavour of RSLinx i.e RSLinx Gateway. To do the mapping we would take the SCADA databse place into Excel and then convert it into a PI Tag database format. This means stripping most of the scada tag attributes out and configuring the appropriate PI tag attributes. Typically the thing to get right are the OPC Topics and how the location codes and point sources are used.also be aware of any scaling conversions that are done in the PLC. Using excel this way allow us to do a comparison afterwards to easily verify that the PI tags have been correctly mapped to the scada tags. If your SCADA purports to be OPC compliant you will just need to verify what component is the OPC server and whether you have the product included in your package and have the correct licence to use. ![]() You will need the PI-SMT toolkit and its Excel add-in, and typically you may have to think about naming conventions and descriptions in order to make the system future proof, a description of H15:3 isnt very informative but its not untypical for systems to have very poor descriptions and incorrect units and ranges.
