Data logger structure
after
Each query command is responded with up to 7 data sets that follow one another without a separator.
These data sets consist of 16 bytes and are encrypted into 32 ASCII characters prior to transmission.
For example, the byte 0x23 is converted into the ASCII characters:
0x32 ("2") and 0x33 ("3").
Therefore, a response consists of up to 7 X 16 = 112 bytes, i.e. 224 ASCII characters.
The date and time (without seconds), the device status and the type of data logger entry are always
transmitted in a data set (byte 0-7, and ASCII characters 0-15).
Also, depending on the entry, the current actual values or set values of the control loops or other
parameters can be entered (byte 8-15 or ASCII character 16-31).
Example of a response:
!:2400:e0:010b01060f3700000177002800d40000110b01060f3800000172003200d20352... ...:80

Repeated output of the most recently read data, this command
does not move the reading pointer. This command can be used to avoid data loss
a communication error has occurred
