Data Format Of Measuring Values - MICRO-EPSILON combiSENSOR 64x0 Instruction Manual

Ethernet Interface
6.2
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.

All measuring values are transmitted as Int32. The measuring value resolution is 24 bits i.e only the most low-
order 24 bits of integer number are used. Hexadecimal range: 0 ... FFFFFF

Description
„MEAS" as an ASCII text
Order number of sensor as int
Serial number of sensor as int
Bit field, which channel available. Two bits per channel are used:
„00"= Channel is not available; „01"=channel available. The low-
est channel is on the most low-order bit ->Thereby determining the
number of channels N possible.
Is not used.
One frame = one measuring value per channel
Measuring value counter (of 1st frame)
Measuring values all channels, starting with the lowest channel
number
