RUN mode without key code
The following table describes the "RUN mode without key code":
Description
Function
In this mode, the sensor measures the exact timing of all
edges of the print marks and sends the exact time stamps
of all detected print marks to the PLC. In this mode, the
sensor uses the values and configured colors that were
taught in during the teach-in process. Without key codes,
the sensor starts measuring automatically as soon as the
NetTime corresponds to the "T
0
-Start" configuration. The
sensor uses the previously defined reading window for
print marks and sends the exact timing of the rising and
falling edges of the print marks.

See the figure below.
Activation
The mode must be activated this mode via Ethernet Power-
link in the "Operation mode" field. "T
0
-Trigger“ includes the
time stamp reference for the sensor NetTime that is used.
Measuring is started with "T
0
-Trigger". This mode must be
deactivated again via the "Operation mode" field.
Prerequisite
The following values must be set before starting:
• Limit values of sending colors and light remission values
of the taught in print marks
• The light remission value for the background
The following parameters must be set before starting:
• Δbx: Width of the reading window for print marks
• Key code = no
Key code use is deactivated.
Feedback
The following data is sent from the sensor to the PLC.
• Mode changes or faults
• The exact timing of the rising and falling edges of the
print marks as a reference for the "T
0
-Trigger" value
• The configured "T
0
-Trigger" value
• Light remission values for each print mark in every
reading window
Speed
Speeds of up to 10 m/s are possible in this mode.
