Does anyone have VB sample code on how to use OPC instead of DDE. Please refer to the following forum topic "VB app using RSLinx on a different drive" for a sample of how I am doing DDE.
in the knowledgebase. It gives a visual basic example that is very good and has a link to the OPC Founation where you can download the OPC Specifications. Also look up the keyword OPC and you will get more information.
