Appendix
Distance configuration
Data set in the bar code scanner to establish a focus position of the laser beam for focus
position switching. The depths of field for the individual focus positions can be obtained
from the specification diagram in relation to the resolution.
Distance detection
Device detecting in 2 graduation distances from objects carrying the bar codes. One exam-
ple is the downward reading of a photoelectric reflex switch arranged beside the conveyor
system. The ranges for focus position switching are defined through combinations of the
switched input "Sensor 1" and the cross-reference list for distance configurations.
Download
Transfer process of the parameter values using the SOPAS-ET configuration software from
the PC to the connected bar code scanner.
In "Online" communication mode, the SOPAS-ET configuration software always transfers the
just modified parameter values in the background automatically and temporarily to the
working memory (RAM) of the bar code scanner with the "Immediate download" option (de-
fault setting). With this option, the current parameter values in the bar code scanner are
constantly synchronised with the modifications that are made on the user interface.
With the "Download on request" option, the user is responsible for comparing them manu-
ally. If individual parameter values have unsynchronized statuses between SOPAS-ET and
the connected bar code scanner, SOPAS-ET identifies these parameters with a blue frame.
Using the context menu (right mouse button), if necessary the modified parameter value on
a register tab (D
OWNLOAD
PARAMETER
VALUE
) can be transferred manually to the bar code scan-
ner. Using the Communication menu, either modified parameter values only (D
OWNLOAD
MODIFIED
PARAMETERS
TO
DEVICE
) or all of the bar code scanner’s parameter values (D
OWNLOAD
ALL
PARAMETERS
TO
DEVICE
) can be transferred.
The parameter values that were temporarily changed in the bar code scanner are only saved
permanently when the storage option "Permanent" (menu CLV640) is selected. The trans-
ferable parameter values depend on the current user level in SOPAS-ET.
Error messages
Messages in coded form with which the bar code scanner displayed a diagnosed error. The
bar code scanner differentiates between four error types: Information, Warning, Error, Fatal
Error. The error messages can be displayed in the SOPAS-ET configuration software on the
System Informationen register tab.
Ethernet interface
Physical data interface with transfer rate 10/100 MBit/s and TCP/IP protocol. The Ethernet
interface can be used alternatively to and also in parallel with the physical interfaces RS-
232, RS-422/485.
Port 2112 (Host interface) is used to output the reading result and port 2111 (Aux interface)
among other things is used to output reading diagnosis data and to monitor the data traffic
on the Host interface. The bar code scanner can be configured using both ports. If the Aux
interface data output via RS-232 is eliminated, existing communication via Ethernet re-
mains active. The same applies to the Host interface, although the data output via Ethernet
can be eliminated separately.
