  You are not going to find anyone with that experience. We are talking about maybe using the easyIO's OPC DA third party, N4 driver on a job coming up. Niagara N4 is usually the front end and programming tool for HVAC networks. N4 supports third party java modules written for it but OPC is not a standard driver for N4. But it is not for alarms and events messages, just point value integration. The hardest part would be resolving the OPC issues between machines. Having the same windows user account at both ends of the opc connnection. And having the opc server service (what ever its name happens to be) run as that user name instead of "system" user. I would recommend integrating with N4 supervisor on a PC instead of in a Jace device for the integration. So you can use opc tools to test com issues. Windows 10 does not like anonymous opc connections, so you need user accounts to match up, and change windows dcom permisisons. Niagara integration should be strait forward once it is talking, but getting it to talk will be the tricky part.
  OPCTI.com has a 3 day course to become an opc expert.
