2 Query error 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 executed.
3 Device-dependent error 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 The syntax of a received command is correct but the command can-
not be executed due to various marginal conditions. An error mes-
sage with a number between -200 and -300 denoting the error in
greater detail is entered in the error queue.
5 Command error 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.
6 User request The sensor is switched over to manual control.
