Format Of The Answers - HBM WE2108 Serie Referenzhandbuch

2.2
After detection of the end character, the received characters are interpreted as command
and an answer is generated in the normal case. Answers consist of ASCII characters and
are concluded with two end characters. The answer to a command is "0" (after correct exe-
cution) or "?" (if errors occur). In the case of queries the WE2108 gives the required value as
answer.
The end characters CR and LF are set ex works. Deviating characters (ASCII code),
which then are output as end character with all answers, can also be set by the user in
the ioSEt menu. CR (0D hex) and LF (0A hex) are stated as end characters in the
examples of this Manual. A start character which is sent before each answer (factory
setting 0 = deactivated) can also be stated in the same menu.

Format of the answers

Entry
Correct command
Correct query (e.g. ASF?)
Measured value query (MSV?;)
Inadmissible parameter value
Blocked function (e.g. legal−for−trade
values)
Unknown command
Incomplete command abbreviations, individual characters and the end character without
preceding command are also considered as unknown command.
The command RES delivers no answer. However, pseudo characters or errors (framing
error) can be generated at the interface by restarting the electronics.
In the broadcast mode (with S98 activated) no answers are output.
The Select command (Sxx) itself delivers no answer, but can cause the output of the pre-
viously stored answer.
The command BDR delivers the answer in the new baud rate.
The number of the characters output as answer differs according to command, but does
not dependent on the current value of the queried parameter. The user software can
either be set to the fixed length or can read all characters up to the end character. This
does not apply for the binary output after MSV?; , see COF command!
