Do I need to buy any additional hardware for that? How can I test this communication without buying any hardware. Usually for modbus we have modscan or modsim. However I am not sure if there is any software for OPC-DA protocol testing. Please let me know if you have worked on it. Thanks,

I will try out this one as soon as I have hardware setup. All I was concerned was, if there is any need for buying additional hardware. Though it looks like that I do not have to buy any additional hardware. Keep your valuable inputs coming to this forum! Thanks,
