Hello Everyone,
My team is hoping to use QuickOPC Lab to read Yokogawa DCS data in a case where there is no OPC server, just HMI and Operator Workstations.
I understand I could use a VBScript. On the OPCLab website, there are VBScript examples on reading OPC items but not sure how to script out to allow for continuous update reads from these OPC items. Also, in our situation, we have about a thousand or more data points, updating at an average rate of say 2minutes.
Our goal is to have this data read in the OSIsoft PI system application. OSIsoft however has an OPC Interface application but we are uncertain if this application would work in reading data pointing to an ordinary HMI or workstation which isn't an OPC Server. OSIsoft recommendation is to usually read from an OPC Server.
Any pointer, use case example or advice would be greatly appreciated.
