Parameterizing tracking in the CLV490:
Explanation Object tracking takes place in every CLV490 in the system. For this purpose, each CLV490
continuously compiles an internal object list. When in slave mode, the CLV490 receives the
required tracking information for the objects in the reading field from the OTC400 via the
CAN bus.
As soon as a successful reading has been made, the CLV490 sends the reading result to
the OTC400 via the CAN bus. The OTC400 then compiles the results with the same name
