I am having an issue connection to an OPC Server that Videojet uses. From what I’ve read, I may need to update my OPC Core components on both machines. However, when I use the link provided and search Ignition, it says their certificate has expired. Is there anyone that can point me in the right direction? Thanks. ---

I’m not sure what link you’re talking about, but OPC Core Components are available directly from the OPC Foundation: [https://opcfoundation.org/developer-tools/samples-and-tools-classic/core-components/](https://opcfoundation.org/developer-tools/samples-and-tools-classic/core-components/) ---

Okay, thanks. When I clicked on the link in the Ignition manual, it took me to a different page than the one you just sent.
