Freelance 2016 SP1 - no connection - Control builder F and OPC Server - installed with trend server on same PC
This system is running on Windows 10. The other Freelance operations stations remain connected. The OPC server is then stopped manually and restarted then a download is possible however the connection is then lost again.
The following is found in the release notes but we not sure what it means?
Freelance Operations and Trendserver and/or OPC server on same PC
If the software packages Freelance Operations and Trend Server / OPC server are installed on the same PC, it must be at least one server configured without a separate user account. Otherwise, the communication between Freelance Engineering and Freelance Operations fails. The operator station can not be loaded and remains in "No connection" (#24958 - RN_20161_007).

If you have OPC server and Trendserver running on the same PC with FE and FO, do not configure a seperate user for the OPC server or the Trendserver.
Not sure that this error is your problem, because in the observed cases FE does not get connection to FO, it is not a problem of connection between FE and the OPC server. Also the connection is never lost, in the sense it is there first, but later disappears. It simply never gets the connection.
