Digital communication

6.1

RS-232 communication

Digital Bronkhorst® instruments can be monitored and operated via RS-232 using the free FlowWare software tools for
Windows. These tools provide a graphical interface to the
The FlowWare toolkit provides functionality for monitoring and operating digital instruments (FlowSuite, FlowPlot),
selection of the active fluid and configuration of the fieldbus connection (if applicable). For instruments that support the
definition and use of multiple fluids FlowTune™ can be used to store fluid definitions in the instrument and select the
active fluid.
Digital instrument parameters are made accessible by FlowDDE, a Dynamic Data Exchange server (DDE) that handles
communication between the instrument and (dedicated) client software in Windows (e.g. FlowPlot). FlowDDE can also be
used by other client applications, such as Microsoft Office or custom made software, built with third party development
software like LabVIEW or a SCADA platform.
The FlowWare tools and associated documentation can be downloaded from the product pages on the Bronkhorst website:

·
If the power and signal connector is set for RS-485 communication, the instrument will not respond to an RS-232
master. In that case, use the
·
After configuring the required parameters, follow the same procedure to leave configuration mode and restore the
original communication settings (otherwise, configuration mode will remain enabled after the next power-up).

Fieldbus communication

Not all parameters described in this document are necessarily available with all digital interface types. For information
about parameter access and availability for Bronkhorst® instruments in a specific fieldbus network, consult the according
fieldbus manual.
