Use these instructions with the camera tunnel setup like this one:
The following settings are found in the configuration table in the Dataman Config Tool.
Enable high frequency light on each camera. For doubling the amount of light coming from the camera.
Disable all trained codes. If a code is trained at a position, it will only read the barcode at the position.
Lower the slave response on the slave cameras. The slave’s Response Timeout is the time in milliseconds that the master waits for a result from a slave camera.
Remove the Trigger Delay on the master camera. The trigger delay you can specify the start and end of how milliseconds or how many mm to wait before starting an image acquisition once the reader receives a trigger. But, if you don’t have enough spacing between objects while trying to read the code, it will cause device errors.
Move the trigger (photocell) closer to the camera tunnel and remove the trigger delay. This will ensure that you will not get any trigger device errors.
Get enough spacing between scanned objects to avoid any multi-reads.
Untrain all the Train Orientation while tuning codes.
PLCs can exchange tag values if they are connected directly to the machine network. Using the “produced” and “consumed” tags, without the need for a message block. See Rockwell’s documentation (Allen Bradley).
