10.6 Configuring the CLV with command strings
The CLV can be parameterized and operated via the terminal interface and the host
interface. Parameters that are not recognized by CLV Setup can also be used by following
the conventions for command strings. This enables special devices, for example, to be
parameterized and new CLV parameters to be configured which may not be recognized by
the CLV Setup program if this is older than the software on the CLV. The CLV Setup user
interface is based on the command language.
The command language accesses the CLV command interpreter directly. It must be used
carefully. The commands sent to the CLV are executed immediately.
Parameter values that have been changed by commands are initially only active in the
current parameter set in the RAM of the CLV. Using a special command, the modified
parameter set must also be copied to the EEPROM so that it is stored permanently.
Otherwise, the changes will be lost when the power supply is switched off.
The O
NLINE MODE
of the terminal emulator in CLV Setup enables the CLV to be parameterized
directly with command strings. Fig. 10-8, Page 10-23 contains the initial screen of the
terminal emulator with the command field and output window which shows how the PC and
CLV communicate with each other.
1. Click in the toolbar.
The T
ERMINAL
E
MULATOR
window is then displayed. The CLV is in R
EADING MODE
.
2. Click P

.
The CLV cancels Reading mode. The "Device Ready" LED is extinguished.
CLV Setup switches the CLV to the P
ARAMETER
mode by issuing an appropriate
command.
Profile 3 Only changes configuration of host interface:
– Activation of RS 422/485 interface
– SICK network protocol (standard)
– Data transfer rate: 38,400 bd
– Data format: 7 data bits, parity odd, 1 stop bit
– Device number: 99
Profile 4 Only changes configuration of host interface:
Reading result is output as soon as evaluation criteria are fulfilled
Profile 5 Only changes configuration of host interface:
– Output of error status "ST" in the “Code-Info/Separator“ block
– Output of CLV: <CR> <LF> in terminator (jumps to start of new line after each
code)
Profile 6 Parameterizes CLV as master in master/slave configuration
– No. of slaves: 1
– Timeout: automatic
Profile 7 As profile 6, but no. of slaves: 2
Profile 8 Parameterizes CLV as slave in master/slave configuration
Profile 9 Parameterizes CLV for
PASS
-
THROUGH MODE
: output of " / " and device number in
header
Profile 10 Starts and ends CLV AutoSetup
Profile 11 No function with CLV 42x
Profile 12 No function with CLV 42x
