Host interface
Main data interface of the ICR890 System with configurable data output format. Allows,
among other functions, the output of the
Ö
reading result in telegram form to the host/PLC.
Works as a gateway in conjunction with the SICK-specific CAN-SENSOR network. Available
with either RS 232 or RS 422/485 version. Provides various transfer protocols. Access to
the ICR890 System for operation and configuration is also possible via the host interface
using the SOPAS-ET Configuration Software. Host interface communication can also be
executed via the Ethernet interface or the CAN interface.
Master/Slave configuration
Special arrangement and technical circuit connection of maximum 8 ICR890 Systems to
one reading station (e. g. multi-side reading) using the CAN interface. Via the master the
combination acts on the host as just one device.
Multi-reading
Selectable number of readings which must each deliver internal results from one and the
same bar code before the ICR890 System generates the reading result.
No read
The ICR890 System did not recognize any or the requested number of codes specified by
the configured analysis conditions during the last
Ö
reading pulse.
No read format
Special configurable data block as a replacement for each expected and unrecognised code
in the data output string of the Host/CAN or Ethernet interface in case of a
Ö
no read.
Consists of the reading data with/without defined error string or is completely eliminated.
In its default setting, the ICR890 System generates the reading data as no read format with
the "NOREAD" error string.
Object distance
Gauge for focusing the camera. Determined, e. g., by means of an MLG Light Grid or
VMS4xx/5xx Volume Measurement System on the conveyor system during reading from
above.
Object height
See object distance.
Parameter set
Data set which is used to initialize and activate the implemented functions of the ICR890
System. Transferred using the
Ö
upload or
Ö
download from the ICR890 System to the
SOPAS-ET Configuration Software or vice versa.
Reading area (DOF)
Depth of field on both sides of the lens focal point at the reading level. Size of the area
depends on the resolution and the reading distance.
Reading diagnosis data
Data which the ICR890 System derives directly from the reading process. The data allows,
among other things, an assessment of the reading quality.
