Parameterizing tracking in the CLV:
Explanation
Object tracking takes place in every CLV in the system. For this purpose, each CLV
continuously compiles an internal object list. When in slave mode, the CLV receives the
required tracking information for the objects in the reading field (consecutive object number,
beginning and end of object, incremental encoder status) from the OTC 400 via the CAN
bus. Depending on the parameter settings, the distance information for focus position
switchover is also sent. The position of the CLV relative to the conveyor belt must be clearly
defined to ensure that the bar code(s), object, and scanner are correctly assigned. A
