Node identification 7.1
After each system start (power-on, reset) the transducer
provides the node-specific parameters (LMT address) so
that identification is possible. See Tab. 6-1 on page 11.
To configure the BTL, the CAN communication module
must be in the pre-operational state. The configuration is
carried out via SDO accessing the relevant objects in the
object directory.
Mode (type of message transmission) 7.2
Depending on which conditions apply to using the
transducer, BTL data may be sent continuously via the
PDO or on demand.
PDO continuous:
In the factory setting, the transducer values are sent –
every 10 ms.
Communication profile
index 1800 to 180F
Sub-index 2 –
254 = continuous
PDO on demand:
Transmission is started by the master application/ –
controller using the request message (SYNC).
Communication profile
index 1800 to 180F
Sub-index 2 –
0...240 = using SYNC object
PDO synchronized on demand:
Settings for objects 1800 to 180F same as for PDO
on demand, plus the following additional settings in
object 1006h.
Possible sampling rates
The BTL can be polled at any desired sampling frequency.
The data is always as up-to-date as possible. For each
stroke length, there is a minimum sampling time of t
min
. The
longest time which can be set is 1 s. All values which lie
outside the range t
min
> 1 s are automatically rejected.
Formula for 1 magnets:
Length
≤
2350 mm
t
min
= (nominal 60 mm)/2800 m/s + CALC
Length > 2350 mm
t
min
= (nominal 60 mm)/2800 m/s * 2
Formula for 2 magnets:
Length ≤ 2750 mm
t
min
= (nominal 60 mm)/2800 m/s * 2 + CALC
Length > 2750 mm
t
min
= (nominal 60 mm)/2800 m/s * 3

Formula for 3 magnets:
Length

3600 mm
t
min
= (nominal 60 mm)/2800 m/s * 2 + CALC
Length > 3600 mm
t
min
= (nominal 60 mm)/2800 m/s * 3
Formula for 4 magnets:
t
min
= (nominal 60 mm)/2800 m/s * 2 + CALC
Formula for FMM:
t
min
= (nominal 60 mm)/2800 m/s + 1700 µs + CALC
CALC = 850 µs (1 magnet)
CALC = 1,000 µs (2 magnets)
CALC = 1,300 µs (3 magnets)
CALC = 1,650 µs (4 magnets)
CALC = 1,650 µs (FMM mode)
