Dynamic focus control
Function for shifting the focal point of the laser beam across a wide range in the reading
plane. The dynamic focus control function is event controlled (e. g. by the distance detector)
or dynamic in the
Ö
Autofocus function.
Error messages
Messages in
Ö
plain text that are used to identify a malfunction on the CLX in Reading mode.
The messages are output on the terminal interface only. Exception: ST = 3 (device error),
which is also output on the host interface. The error messages can be displayed in extended
mode under T
ERMINAL EMULATOR
in the "CLV-Setup" program.
Error status
Identifier output with the reading result by the CLX for errors that were diagnosed while the
bar code was being read. The entry for the host interface is made in the separator of the
Ö
data output string and must be enabled using the parameters (enabled by default).
Focus position
Distance of the focal point of the emitted laser beam in front of the reading window. Can be
varied using the optical components in the CLX. Creates a distance-specific depth of field
(DOF) in which he bar code can be detected.
Functional interfaces
Switching inputs and outputs on the CLX.
Good Read
The CLX successfully detected a bar code or the required number of bar codes specified by
the evaluation parameters during the
Ö
reading pulse.
Header
Data block in the reading result on the
Ö
host interface. Used as a header in the
Ö
data
output string for the subsequent data content of the bar code. Contains reading diagnosis
data, control characters and alpha-numeric constants, depending on the configuration
(empty by default).
Host interface
Main data interface on the CLX with configurable data output format. Used to output the
Ö
reading result in telegram form to the host/PLC. Integrates the CLX in the SICK network
or builds a master/slave arrangement. Used as gateway in the CAN Scanner Network. Can
be physically switched to RS 232 or RS 422/485. It supports various transmission proto-
cols.
Increment management
Used in certain applications to separate bar codes with identical contents that move during
the reading procedure and assign them to the objects.
