Здравствуйте!
В новый проект добавил переменные из "MasterOPC Universal Modbus Server" OPC-UA. Вывел отображения переменных на экран. Запустил MasterOPC OPC-UA, проект Simple-Scada, Client-Scada. Всё работает без ошибок.
В этот же проект добавил скрипт, вызываемый по изменению переменной. Сама переменная не изменяется в этом скрипте. В OPC-UA эта переменная опрашивается раз в 100 мс. При запуске MasterOPC OPC-UA и Server Simple-Scada, Server Simple-Scada зависает. При остановке MasterOPC OPC-UA, Server Simple-Scada развисает.
Из Server_log:

---- REMARKS ----
The server may have rejected the connection because it does not trust the client (e.g. certificate problem); check the diagnostics on the server side, if possible.
A possible cause of this error could also be that the OPC-UA server is not running, or that it has rejected the connection due to security reasons.
[00000000ms]localhost:55007/MBUAServer/: (no description available) = BadConnectionClosed.
В списке ошибок нет имени переменной с которой связан скрипт.
В скрипте нет ошибок по скольку этот же скрипт работает с другим OPC DA.
