The parameter is dependent on the implementation in the Data logger and can accept the
following values:
-
Parameter value with 1 to 10 places (decimal value without sign, represented in
ASCII).
-
Character string with up to 256 characters.
Note:
The structure of the response telegram can in some cases differ from the standard (e.g. the
measured value telegram)!
Only if the received “ID” agrees with the one set in the Data logger, does the Data logger
send a response telegram.
7.1.3 Optional framing with 16Bit CRC
Optionally, the commands can be sent with a framing and 16-bit CRC checksum.

The Data logger identifies the call variant with framing and 16-bit CRC and also sends the
response in this format.

The initial value of the 16-bit CRC is 0xffff.
