Working with OPC can sometimes require the configuration of Microsoft DCOM. For some, this becomes a major pain. Luckily, there is technology out there to make things much, much simpler and quicker.
OPC Tunneling technology creates a "tunnel" so OPC servers and OPC clients can pass data back and forth, without using DCOM. The video below explains how this is done using a tunneling product from Cogent.
It is important to note that some tunneling products on the market can compromise security and so if you have specific security policies you need to adhere to, please consult with your tunneling vendor to make sure everything is compliant.
Once you watch the video, you can download a tunneling product and try it out for yourself. Click here to download OPC Tunneling from Cogent.
