OPC client/code sample for Opcserver


Does opto22 have sample code to talk to opto22 opcserver?


Hello tpham_climatemaster,

Welcome to the forums! There is one VB 6 example included with install. Assuming you chose default locations and have 9.3, it’ll be in:
C:\Program Files (x86)\Opto22\PAC Project 9.3\Easy OPC VB Forms.

There is a document that should be read first that is in that same directory:

Writing an OPC client is no trivial matter, is that your intent? Can you tell us a little more about your application?
