Chapter 5 – Components and Operation
5.2.6.4.4 CAN Message Object 3 (D Identifier; Transmission Object)
For interpreting the values of Message Object 3 also refer to Table 8 on page 20. This
Message Object is used for commissioning, service and troubleshooting.
5.2.6.4.5 CAN Message Object 4 (Reference Transponder, transponder pro
-
gramming; Reception Object)
It is possible to activate and deactivate the reference transponder via the CAN bus.
For this it is necessary to send a Message Object with the same address as Message
Object 1 and a length of 5 bytes. The reference transponder may be de-/activated
via byte #5.
The programming of a transponder is initiated by setting byte #5 to the value 02. This
byte should be reset after 8 to 100 ms.
The programming of a transponder takes 100 to max. 200 ms. Afterwards the new
code is read and may be checked via Message Object 1. In case the programming
wasn‘t successful repeat the procedure.
