Instruction Manual ES-FLOW™

3.4

Digital parameters

Each instrument is controlled internally by a number of digital parameters, most of which can only be accessed via digital

communication. Each communication protocol uses its own methods for communicating with instruments and accessing

parameters.

FLOW-BUS

In a FLOW-BUS system, instrument configuration and operation can be done using the free Bronkhorst® FlowWare tools.

These tools provide a graphical interface to the ProPar protocol (used by FLOW-BUS), for monitoring and changing

instrument settings. Digital communication between the instrument and the client software (e.g. FlowPlot, FlowTune™) is

handled by FlowDDE, a Dynamic Data Exchange server (DDE), the core component of the FlowWare software.

The FlowWare tools and associated documentation can be downloaded from

http://www.bronkhorst.com/en/downloads

Modbus

Monitoring and operating instruments in a Modbus system can be done using third party software as a master device, such

as LabVIEW, ModScan, or a Modbus PLC.

PROFIBUS-DP

Monitoring and operating instruments in a PROFIBUS DP system can be done using third party software as a master device,

such as SyCon® (by Hilscher GmbH) or Step 7 for PLC (by Siemens).

To configure a device, a so-called GSD file (General Station Description) can be loaded into the software. The GSD file

contains all necessary configuration information to operate the device in a PROFIBUS DP system, including communication

and network configuration, all available operating parameters, their data types, and supported data ranges.

A GSD file for Bronkhorst® instruments can be downloaded from

http://www.bronkhorst.com/en/downloads

DeviceNet™

Monitoring and operating instruments in a DeviceNet™ system can be done using third party software as a master device,

such as SyCon® (by Hilscher GmbH) or Step 7 for PLC (by Siemens).

To configure a device, a so-called EDS file (Electronics Data Sheet) can be loaded into the software. The EDS file contains all

necessary configuration information to operate the device in a DeviceNet™ system, including communication and network

configuration, all available operating parameters, their data types, and supported data ranges.
