Hello, I was able to locate this post which seems similar: OPC UA - Opto 22 groov EPIC and SNAP PAC.
Generally it looks like this driver can connect, but not necessarily directly to the device's IO cards. If this is an issue, Opto 22 has a workaround to connect to the cards included in that forum reply as well.
If you have additional questions on these Opto22 devices, or drivers, you can find Opto22's forum here: https://forums.opto22.com/, and their training here: Opto22 - PAC Control Basic, as linked by Benson on that previous forum post. Good luck with these new devices!
