OPC error messages
-
Errors usually lead to a termination. The reported error must be removed and the driver must be restarted.
-
Warnings are purely for information about an (unexpected) event that has occurred (operation could not be executed, a default value had to be used, ...). In some circumstances they may prevent the execution of an operation, or a series of operations, but not the program run.
