Description
Enabled: Operating mode in which attempts
•
are made to process one to five of the saved
programs at each trigger. You use the follow-
ing parameters to specify how images are ac-
quired and with which saved programs they
will be processed.
Disabled: Mode in which processing is per-
•
formed with only one saved program at each
trigger.
First read result:
•
The programs contained in the program se-
quence are processed one after the other. Fol-
lowing the first successful processing
procedure, processing is stopped and the re-
sult is output.
Best read result:
•
The programs contained in the program se-
quence are processed one after the other. All
successful processing procedures are com-
pared with each other. Once all processing
procedures are completed, the best read re-
sult is output.
All read results:
•
All programs contained in the program se-
quence are processed one after the other. The
result is output for each program.
Restriction: This setting is not supported in
PROFINET mode with Ident profile or during
operation using a CM.
When selecting result output: "Best read result",
set the comparison criterion. The "Quality" of a
result is evaluated based on the comparison crite-
rion.
Note
Only the selection "Overall quality" is valid for all
code types and verification standards.
If you want to use a different quality criterion,
make sure that this criterion is calculated with the
selected settings. You can find the supported
qualities according to verification standard at
Program format text (Page 76). If a result is com-
pared in processing mode that does not provide
the selected quality, the setting changes to the
overall quality, which can lead to unexpected
results.
