6.2 Data Format of Measuring Values
All measuring values, recorded at a time, are combined into a measuring value frame (One measuring value
per channel).
Several measuring value frames are combined to a measuring value block and then transmitted together with
a header as a TCP packet.
All measuring values and the header are transmitted in little-endian format.

Channels
(Bit field)
64 bit
Bit field, which channel available. Two bits per channel are used: „00“=
Channel is not available; „01“=channel available. The lowest channel is on
the most low-order bit ->Thereby determining the number of channels N
possible.
Status 32 bit Is not used.
