Keyence IV Camera Setup Instructions
Part Numbers and Options
Initial Setup and Wiring
Blue wire goes to DC Common (Negative) and Brown wire goes to
Positive for Power
I/O Settings > Input > I/O Polarity : We only use PNP
Polarity in the plant.
I/O Settings > Input > Enable program switching: This lets
us change programs in PLC
I/O Settings > Input > Input Assignment : Set and land
wires this according to the guides on the next page and the Color
codes above. Guide is summarized below. P00 is highest used:
IN1=Ext Trigger P01 is highest used: IN1=Ext Trigger, IN2=bit0
P02-P03 is highest used: IN1=Ext Trigger, IN2=bit0, IN3=bit1
P04-P07 is highest used: IN1=Ext Trigger, IN2=bit0, IN3=bit1,
IN4=bit2 P08-P15 is highest used: IN1=Ext Trigger, IN2=bit0,
IN3=bit1, IN4=bit2, IN5=bit3 P16-P31 is highest used: IN1=Ext
Trigger, IN2=bit0, IN3=bit1, IN4=bit2, IN5=bit3, IN6=bit4
I/O Settings > Output: Output Settings can be left at default
while the camera is running Camera should be set to One-Shot. If
default times do not work well due to PLC timing or slow network
connection, ON Time may have to be increased. Output Type can be
temporarily set to Latching when testing Outputs during wiring. But
DO NOT leave it set this way.
Advanced > Environmental > Change Network Settings : Enter
IP Address settings here
Image History > Logging Settings : Change this to All during
setup so that you will have a good number of images saved when you
want to test the programs offline or adjust tolerances
Advanced > Setup Adjustment > White Balance : If close
colors are being judged, stable performance of the camera would be
improved by Enabling White Balance Adjustment. This eliminates any
overcast color on all images that can be caused by ambient
lighting.
File > Batch Backup : This will let you back up the cameras
settings and each Program setting. You can also choose to save all
images in the image history.
Individual Program Settings
Sensor Setup > Image Optimization > Trigger Options >
Trigger Options : Trigger should be set to External Trigger so that
PLC can trigger the camera. Delay should be set to 20-50 ms.
Sensor Setup > Image Optimization > Extended Functions
> Lighting Mode : Lighting is usually set to Flash so that bulbs
last longer. Light will turn off between Triggers in this mode. If
the image is not bright enough, or Flash bothers operators,
Lighting can be set to Continuous for individual programs. Lighting
will not turn off between Triggers in this mode unless P00 is set
to Flash mode or left blank.
Sensor Setup > Image Optimization > Brightness Adjustment
: Brightness and Imaging mode can be set automatically or adjusted
manually. Setting should be bright enough to distinguish colors or
outlines, but not so bright that colors are washed out or glare is
introduced. It is suggested to use the same settings for all
similarly colored parts. This will make it easier to test programs
for Passing and Failing the correct colors. If individual color
program settings are all different, colors may Pass / Fail
correctly when testing images in the image history, but actually
Pass / Fail incorrectly in Run mode. Set lighting by putting all
similar colors in front of the camera and setting the brightness
and mode that distinguishes them the best. If colors are very
close, or glare is an issue, a Polarization Lens can be added.
Brightness has to be increased after adding this lens, because it
dims the lighting somewhat.
Sensor Setup > Image Optimization > Focus Adjustment :
Focus adjustment can be set automatically of manually It is
suggested to use the same settings for each program that looks at
the same part. This will make it easier to test programs for
Passing and Failing correctly. If individual program focus settings
are all different, images may Pass / Fail correctly when testing
images in the image history, but actually Pass / Fail incorrectly
in Run mode.
