Example Opc client using OPC Labs client software

You will need..

Opc Labs library - from http://www.opclabs.com/products/quickopc/downloads
Kepware Opc server - from here https://www.kepware.com/products/kepserverex/

In Kepware open up kepware config.xml and update the runtime project

Nb you need the Memory based driver and AllenBradley ethernet installed to load the config

In kepware OPC UA configuation make sure 127.0.0.1 endpoint uses port 49320 and no security policy (you can set it to need signing but then you must trust "sigopc" in trusted clients..)
