Error messages
Messages in plain text or coded (4-digit alphanumerical character) that are used to iden-
tify a malfunction on the ICR845-2 in Reading mode. The messages are output via the aux-
iliary interface only. Exception: ST=3 (device error), which is also output on the host
interface. The error messages can be displayed in the Terminal Emulator of the CLV-Setup
configuration software if requested by the user.
Error status
Identifier output with the reading result by the ICR845-2 for errors that were diagnosed
while the code was being read. The entry for the host interface is made in the "Reading data"
field of the data output string and must be enabled by configuration (disabled by default
in the ICR845-2).
Ethernet interface
Physical data interface with high transmission rate (10/100 Mbps).
ICR845-2 uses this to output the content of a reading pulse stored in the image buffer mem-
ory via FTP for diagnositics if reading problems occur. It can also be used for parameterizing
with CLV-Setup (TCP/IP) (port 2111) instead of using the serial auxiliary interface (RS-232)
or to output the reading result (port 2112) instead of using the serial host interface
(RS 232, RS 422/485)
Focus position
Distance of the ICR845-2’s focal point in front of the reading window. Creates a distance-
specific depth of field (DOF) via the optical components of the ICR845-2, in which the bar
code can be scanned
Functional interfaces
Digital switching inputs and outputs on the ICR845-2.
Good Read
The ICR845-2 detected a code or the required number of codes specified by the evaluation
parameters during the reading pulse.
Header
Data block in the reading result on the host interface. Used as a header in the data
output string for the subsequent data content of the bar codes. Contains up to 10 elements,
consisting of reading diagnositics data and/or constants (control characters, letters, digits),
depending on the configuration. The "Header" block is empty in the default setting of the
ICR845-2.
Host interface
Logical main data interface on the ICR845-2 with configurable data output format. Used to
output the reading result in telegram form to the host/PLC. Can be physically switched to
the serial data interface (RS 232, RS422/485), to the CAN interface or to the Ethernet in-
terface (port 2112). Works as a gateway with the SICK-specific CAN scanner network. The
host interface supports various transfer protocols. With this interface, access to the
