Configuration

5.1

Default settings

The transducer is supplied with
the following default settings:
– Station address 126
– Resolution:
Position 5 µm
Velocity 0.1 mm/s
– Maximum working/useful area
5.2

Presets

The service Set_Slave_Address
can be used to configure the sta-
tion address. For this service you
need a DP Master Class 2. The
GSD file BTL504B2.GSD (trans-
ducer system) is used for configu-
ration. The GSD file provides all
the information required for set-
tings. For configuring, the Siemens
COM PROFIBUS can be used for
example.
When opening the BTL
housing make sure no
parts get into the device.
When closing up the cover en-
sure the gasket is sufficiently
compressed. Tightening torque:
0.8 Nm
For use in standard PROFIBUS
systems the station address and
the termination resistor are set
before startup using the DIP
switches S1.1...S1.10 which are
built into the BTL (➥ ➥ ➥ ➥ ➥ Figs. 5-1 and
5-2).

5.2.1 Station address
Values from 0 - 125 can be used
for the station address. In a net-
work each address can be used
only oince! For value 126 the ad-
dress 126 or the last address set
using the Set_Slave_Address ser-
vice is used. A value of 127 resets
the BTL to its default condition.
Since 127 does not represent a
valid address, bus operation is
then not allowed.

All address settings only become
effective after a power reset.
Changes which are made while
power is on do not therefore have
an immediate effect.

5.2.2 Bus termination

To ensure a reliable rest signal
level the bus must be appropri-
ately terminated on both ends as
shown in Fig. 4-2. The BTL5-T al-
lows the bus to be terminated in-
ternally. To do this set DIP
switches S1.9 and S1.10 to ON,
➥ ➥ ➥ ➥ ➥ Fig. 5-2. For IP 67 the bus ter-
mination resistor suggested in Fig.
4-6 must be used. Then the inter-
nal bus termination should not be
activated (S1.9 and S1.10 OFF)!
Stub lines should be avoided
whenever possible.
