3.6.3
Digital fieldbus operation (RS485)
The following optional fieldbus interfaces are available for
EL-PRESS™
instruments. For all mentioned fieldbus systems,
except FLOW-BUS, instruments act as slaves on the master/slave bus system. There is no mutual communication between
slaves, only between master and slave.
FLOW-BUS
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
protocol (used by FLOW-BUS), for monitoring and
changing instrument parameters.
The FlowWare toolkit provides functionality for monitoring and operating digital instruments (FlowPlot, FlowView) and
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 define and store fluids 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:
FlowWare can only be used if the 9-pin D-sub (power) connector is configured for RS232 communication. If necessary , use
the power-up functionality of the
to switch to configuration mode and enable RS232
communication.
After configuring the required parameters, remember to leave configuration mode and restore the original
communication settings (otherwise, configuration mode remains enabled after power down).
