Non-guarantees
From OPC Labs Knowledge Base
- It is not guaranteed that objects addressed in EasyXXClient method calls will end up in a single OPC call to the target OPC server.
- It is not guaranteed that objects addressed in EasyXXClient method calls will appear in the OPC call(s) to the target OPC server in the same order as on input.
- If you call EasyXXClient.Method1 on time1 and you then call EasyXXClient.Method2 on time2, before EasyXXClient.Method1 returns, it is not guaranteed that the OPC operations for Method1 will be called before those for Method2.
