There is no built in handshaking with datasocket that insures you get every value. You do get messages when the value has been changed, but these messages don't queue up. So if a value has been changed and you got a message but haven't processed it yet, then the next change won't send another message and you will have missed an update. You can implement your own handshaking if you like by having the reader write to an acknowledgement item to tell the server that it has read a value and the value can be updated again.
