Interfaces – Chapter 9
9.4 CAN
The internal Full CAN module is based on the CAN specification V2.0 Part B. Both
standard and extended frames can be sent. You can set the CAN parameters (bit tim
-
ing, identifier, standard/extended frames) via the system monitor (see 10 „Configu
ration of the System via the Service Interface“ on page 48).
Different CAN message objects can be output. You can configure whether telegrams
are output permanently with the adjustable update rate or only when a transponder
is in the field. In addition, remote operation can also be set. The objects are activated
by entering an address other than 0 in the CAN menu (see section 10.2.8 „Basic
C(A)N-Parameters“ on page 62).
9.4.1 CAN Message Object – Y-Identifier, Send Object
9.4.2 CAN Message Object – X-Identifier, Send Object
9.4.3 CAN Message Object – D-Identifier, Send Object
