Components and Operation – Chapter 5
5.2.6.2 System Monitor
In monitor mode, the system is configurable via a menu. Please refer to section 6.2
„System monitor“ auf Seite 28.
5.2.6.3 Positioning Pulse
The digital positioning output indicates the crossing of the center line of the antenna
in direction of travel (x direction). Its duration is adjustable within a millisecond pat
-
tern.
5.2.6.4 CAN Bus
5.2.6.4.1 Description
Either Basic- or Full-CAN mode are configurable. The system monitor is used for set
-
ting the CAN parameters (also refer to section 6.2.2.4 on page 34). The internal CAN
module is based on the CAN specifications V2.0 part B. It is possible to transmit ei
-
ther standard or extended frames (adjustable). The system monitor is used for set
-
ting the bit timing as well as the identifier.
It is possible to output 3 different CAN Message Objects and receive 1. Depending
on the configuration, it is possible to distinguish between permanently output tele
-
grams according to the set update rate or telegrams output only while a transponder
is within the field. In addition, remote operation is selectable.
The objects are activated in the CAN menu by input of an address different from 0
(also refer to section 6.2.2.4 on page 34).
5.2.6.4.2 CAN Message Object 1 (Transmission Object)
5.2.6.4.3 CAN Message Object 2 (A Identifier; Transmission Object)
For interpreting the values of Message Objects 2 also refer to Table 8 on page 20.
This Message Object is used for controlling parameters.
