Write to OPC

Postby Marc Vanzegbroeck » Mon Nov 29, 2021 9:40 am

Hi,

Does anyone already had to write to, or read from, a OPC server with FW?

If so, can you give an example?
Regards,
Marc

https://documentation.unified-automation.com/uasdkc/1.8.0/html/clientgettingstarted1.html

Also google for IID_IOPCServer vba and you may find some useful examples
