PROFIBUS settings (only LES 36/PB and LES 36HI/PB)
For PROFIBUS devices, you can set the slave address and the baud rate in the PROFIBUS
tab.
Figure 9.2:
PROFIBUS settings
Automatic detection of the baud rate / automatic address assignment
The LES 36…/PB supports automatic detection of the baud rate and automatic address
assignment via the PROFIBUS.
The address of the PROFIBUS participant can be set automatically by the commissioning
tool of the PROFIBUS system (a class 2 PROFIBUS master). For this purpose, the slave
address must be set to value
126
in the sensor (factory setting). This is performed by means
of LESsoft or via the display.
The commissioning master checks whether a slave has address
126
and then assigns this
slave a slave address smaller than 126. This address is permanently stored in the participant.
The changed address can then be queried (and, if necessary, changed again) via the display
or LESsoft.
The following baud rates can be set:
Note!
After changing the PROFIBUS slave address via the display or LESsoft, a power-on reset
must be performed in order to permanently accept the address. For the changed settings
to take effect, they must be transferred to the sensor!
