Software
When using a pc to communicate with IQ + FLOW® 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: an IQ + FLOW® instrument set for RS485 FLOW-BUS or Modbus communication will not react 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). For multi-channel instruments the communication type can be set
with the rotary switches.
Slave address, baud rate and parity setup
The IQ + FLOW® instrument is configured as specified on order. If there is a need of changing any of the specified
settings, see the tables below for the supported configurations.
