Additionally, the instrument can be provided with one of the following optional digital fieldbus interfaces:

CANopen

DeviceNet™

EtherCAT®

EtherNet/IP

FLOW-BUS

Modbus (ASCII / RTU / TCP)

POWERLINK

PROFIBUS DP

PROFINET

The default communication protocol of the instrument (analog, digital RS-232 or fieldbus) is specified at ordering time.

2.8.1

RS232 communication

Using a Windows computer, the instrument can

be monitored and operated via RS-232. For

operation, the free Bronkhorst FlowWare tools

can be used, providing a comprehensive user

interface to the digital instrument functions.

This example uses the following components:

EL-FLOW® Select

RS-232 T-part cable (art no. 7.03.366)

RS-232 to USB converter (art no. 9.09.122)

Windows computer (for readout and control)

Plug-in Power Supply (PiPS, art no. 7.03.422)

Connect the T-part cable with the 9-pin D-sub connector on the side of the instrument and use the RS-232/USB converter to

connect the other end of the cable with a free USB port of the computer.

For communication with a

PLC or other

controlling device, a 9-pin D-sub cable with a loose end (part no. 7.03.004,

7.03.536 or 7.03.537) can be used. Consult the

RS-232 hook-up diagram

for wiring details.

For RS-232 communication at baud rates up to 38400 Baud the maximum allowable cable length is 10 m. For higher

baud rates, use a maximum cable length of 3 m.

For more information about communication through the RS-232 interface, consult the

RS-232 manual

The FlowWare tools and associated documentation can be downloaded from the

Accessories and software

section on

the Bronkhorst® product pages (
