Question:
When E3 is an OPC Client and communication happens via E3 Studio, it works properly. However, when executing the Domain, it does not work. Why does this occur?
Solution:
This happens because Studio and E3Run (the process responsible for executing the domain) run in different user accounts.
The Studio runs in the account of the user logged into Windows, while E3Run (and E3Server) runs in the SYSTEM account, and the OPC Server may not be prepared to work in this account.

NOTA: If OPCDriver’s ServerMachine property is currently displaying the IP number, you must replace it with the following structure: \\MachineName.
