    However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these are marked to help prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current, and voltage loss must be kept as low as possible.

    Digital operation over RS232 can be established when using the following setup. Using a RS232 cable or a USB- RS232 converter with a PC will allow you to use (free) Bronkhorst® software for Windows, such as FlowDDE and FlowPlot. See also section 3.4. Digital RS485 operation With digital operation over RS485 a bus-system with multiple instruments can be set up.

    2.11 Calibration Each IQ+FLOW® instrument is factory calibrated. Bronkhorst certifies that all instruments meet the rated accuracy. Calibration is performed using measurement standards traceable to the standards of the Dutch Metrology Institute (VSL). Calibration certificates are included in the shipment. When operated properly (clean gas, no pressure shocks, no vibrations, no thermal shocks, etc.), regular maintenance is not required.

  • Page 17: Basic Rs232 Operation

    3.4.2 Dynamic Data Exchange (DDE) RS232 communication can be used for operating the instrument using the Bronkhorst® FlowDDE server application. Dynamic Data Exchange (DDE) provides the user a basic level of interprocess communication between Windows applications. FlowDDE is a DDE server application. Together with a client-application, either self-made or with a SCADA- program from third parties, it is possible to create an easy way of data exchange between the flow controller and a Windows application.

    DDE are for example MS-Office, LabVIEW, InTouch and Wizcon. Bronkhorst® software applications 'FlowView' (left) and 'FlowPlot' (right) FlowDDE and other Bronkhorst® applications are available on the support CD or can be downloaded from the product pages on the Bronkhorst website: www.bronkhorst.com/products 3.4.5...

    Bronkhorst® 3.5.1 Hook-up These illustrations show examples of IQ FLOW® instruments in a RS485 bus-system. When the power consumption is more than 15W, two separate power supplies are required due to the maximum power supply of 15 W for one PiPS.

  • Page 20: Software

    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.

  • Page 21: Basic Parameters And Properties

    Most instrument parameters can only be accessed with digital communication. For each communication protocol the instrument parameters are accessed differently. When using Bronkhorst® software programs FlowView or FlowPlot, easy access is provided to the mostly used parameters by menu interfaces. When using other communication methods the...

    The controlling algorithm for the valve handled by the micro-controller consists of several parameters which can be set. Although many parameters could be accessed, Bronkhorst advises not to change these parameters because during manufacturing the controller is optimized. Changing of controller settings should be performed by or under supervision from trained service personnel only.
