Data transfer method — how the data are transferred
Whenever the TCP/IP socket connection has been established (either by an application on
a PC or by the UE410-EN itself), there are two possible ways how the data sets can be
transferred:
The application requests the data set(s) per command message (Polling Mode) or
the UE410-EN auto-updates the data sets as per configuration (Auto Update Mode).
For both methods the following structure of messages applies.
