Dear Daniel, How Can I configure the OPC Server and write the addresses in correct way for GE Fanuc (90-30) using Proficy machine Edition as this is the first time for me to use OPC. Best Regards, Mahmoud Hazem ------------------------------------------------------------------------------------------ |

Hello Mahmoud; There is no unique way of configuring an OPC server for a specific OPC clinet, each manufacturer requires different details. You should decide on one manufacturer (Proficy offers some OPC servers that you could use easily) and read their instruction manual. But there are basic notions on OPC that can be useful to you. First of all, OPC stands for "OLE foe Process Control" and it evolved from Microsoft's OLE tools. What is OLE? Say you write a report in Word and develop a table in Excel that you need to show in your report, you can simply take a copy of the cells you need and embed them in the Word document. You can then click on them and open the original speadsheet and change sme values, form the Word document. That is possible beacause Object Linking and Embedding (OLE) has been built in bopth appications. In the same way you can embed Word in Powerpoint, or Excel graphs,... No programming required once OLE is installed and working properly. OPC is an extension of OLE developped for automation, to make drivers and pilots much easier to write. Instead of developping a secific driver that allows this machine to talk to this equipment, you use a pair of translation devices known as OPC server (the slave)and OPC client (the master) on the main computer where both software reside. In your case, you would need the SNP OPC server on your PC, cpnnected to all your GE Fanuc 90-30 CPUs. it will collect a list of tags representing the values you will share with your WinCC Scada (if Proficy does not create tags for these values, the OPC server application will make you create them. The OPC client,part of your WinCC installation, will connect to the OPC server and present a list of all available tags (values from your 90-30 CPUs) so that they can be individually connected to the SCADA, Once the OPC cllient and OPC server are correctly installed and confiured on your PC, the connection between the two is very simple (to speak technically, this is due to COM and DCOM standards from Microsoft, but at this point you don't need to worry about that, generally). One complication is that there are now quite a few variations on the original OPC standards: OPC-DA, OPC XML, OPC A&H, even OPC UA (Unified architecture) that no longer reuqires COM/DCOM so it can work on non-Microsoft platforms . Just make sure that the same variety is used by the OPC client and server. For information on OPC serverss (in general) this Matrikon document can be useful: https://www.automation.com/pdf_articles/Guide_to_OPC.pdf For information on your OPC client, see the winCC v14 document provided earlier. Hope this helps, Daniel Chartier |
