Start-up FlowFix.exe and select COM-port. Then the configuration screen will appear.
Enter slave station address and press [OK]. Changing baud rate will have no effect for PROFIBUS devices because the
slave will adapt automatically to the baud rate of the master. Baud rate is only meant to be read. Re-address action
can be checked using the option ‘Live list’. This gives an overview of all masters and slaves connected to a PROFIBUS
segment (see example in previous paragraph).

RS232:
OTHER PROGRAMS
It is also possible to read and or change slave station address or baud rate by means of any program via RS232 using
the COM-port of your PC on 38400 Baud. This can be achieved using the FLOW-BUS protocol.

S ON TOP OF INSTRUMENT
With the micro-switch on top of the instrument it is possible to change and readout the settings for slave station
address and baud rate. The Led’s will indicate the tens of the address with green flashes and the units with red
flashes. For baud rate-indication both Led’s will flash (baud rate will adjust to master setting automatically and is
therefore read-only).
