Step 1.3. Specify Log In Requirements

Your OPC Server determines whether or not login is required.

If log in is required, log in for the Advanced Viewer is as follows.

  • Login will only be requested one time for the current user.
  • The Login Panel will list the log in for the OPC pseudo-project.

You can add saved logs in the Login Panel for an Advanced Viewer project.

  • When cancelling a login, items display as unavailable.
  • Log out Items display as unavailable and cannot be set.
  • Users can log into more than one OPC Server at a time. A user can log out of one Server; Servers that the user is still logged into will continue to display their values; the values can be set.
  • If you are using the Advanced Viewer in a Vista operating system and are configuring DCOM in a domain, set the Advanced Viewer ptopc service (ptopc.exe) to login as a specific domain user.
