The trace number is derived from the sequence in which the trace is output in the process
data (see Table 8.8).
If the trace number used by the vehicle control unit changes during an active switch function
or the second trace disappears, then the currently used trace number is transferred to the
sensor.
This does not cause the internal settings to change. These settings are only changed again
when the switch function is deactivated by writing a '0' and then reactivated.
Operational sequence of the "Switch" function
When should the
SwitchNumber
function be activated?
1.
The system informs the vehicle that there is a switch ahead.
Ideally, this happens 10 … 200mm before the sensor reaches the midpoint of the
switch and the trace becomes wider.
2.
The vehicle notes which guide trace it is currently following. The guide traces are
numbered in ascending order from 1 to 6.
The sequence is derived from the sequence in which the edges are output in the pro-
cess data (see Table 8.8).
3.
This trace number must be written to the
SwitchNumber
index (UART index 170
d
and
CAN index 2012
h
[0
h
]) or sent via the query with the process data with byte 2 PD-In1.
4.
Internal adaptation of the values in the sensor to the trace which the vehicle is cur-
rently following takes place once only.
The effect on the output traces becomes apparent within the maximum time of one
measurement cycle (10ms) after the query is sent for the first time.
Deactivation of the "Switch" function
1.
Writing a ’0’ in
SwitchNumber
(UART index 170
d
and CAN index 2012
h
[0
h
])
or
2.
Writing of ’0’ in byte 2
PD-In1 during
the process data query.
NOTE
If a trace number which is not present is written, an error occurs. In this case, bit 13 is set
in the
Status
index (UART index 200
d
and CAN index 2020
h
). The switch function is not
activated.
The switch function is active if bit 12 is set in the
Status
index (UART index 200
d
and CAN
index 2020
h
).
Solution: Write the correct trace number.
