Software

When using a pc to communicate with LIQUI-FLOW

mini instruments only the FLOW-BUS protocol is supported by Bronkhorst

software. When using Modbus operation, software from third parties, such as LabView, ModScan or a Modbus PLC must be used

to serve as Modbus master.

Note: a LIQUI-FLOW

mini instrument set for RS485 FLOW-BUS or Modbus communication will not respond when

connecting to an RS232 configuration. When required press the micro-switch according to the procedure in section

3.3.1 at start-up to activate the “Configuration Mode”. The baud rate and bus type are set to 38K4 and RS232

FLOW-BUS (Propar).
