Query error
This bit is set in either of the two following cases: the controller wants to read data from the
sensor but has not sent a query, or it sends new commands to the sensor before it
retrieves existing requested data. A frequent cause is a faulty query which cannot be exe-
cuted.

This bit is set if a sensor dependent error occurs. An error message with a number
between -300 and -399 or a positive error number denoting the error in greater detail is
entered in the error queue.
4
Execution error
This bit is set if the syntax of a received command is correct but the command cannot be
executed due to various marginal conditions. An error message with a number between
-200 and -300 denoting the error in greater detail is entered in the error queue.
5
Command error
This bit is set if an undefined command or a command with incorrect syntax is received. An
error message with a number between -100 and -200 denoting the error in greater detail is
entered in the error queue.
