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).

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).
