5.2. Remote meter control using program FLOSET 4.0
Flowmeters of the type series FLONET FXx11x and FLONET FH30xx are provided with digital interfaces
RS-485 MODBUS RTU and HART
®
.
Remote control of flowmeters FLONET FXx11x and FLONET FH30xx is facilitated by the serial
communication interface RS-485 MODBUS RTU.
Across such interfaces the meter can be connected as subordinated equipment to a computer (a personal,
notebook or tablet computer) with Windows XP or a higher OS upgrade (Linux, iOS) and JAVA 8u40 or a
higher upgrade thereof installed. The remote control mode of operation further requires installation of the
following software:
Configuration program FLOSET 4.0, and
File *.floc related to the flowmeter type concerned.
Using these software tools, the user may set parameters and read the values of all meter variables as with
the manual meter control mode.
Program
FLOSET 4.0
and file
*.floc
associated with the
given meter type are not included in the basic
scope of deliverables.
A complete software package (on a CD) for remote meter control including the USB/RS-485 convertor
complete with connecting cables can be supplied on request.
5.2.1. Flowmeter connection to a communication line
The terminals of the RS-485 communication interface are located on the meter terminal board. Prior to
connecting the communication line, turn off the meter power supply.
Line termination resistor: 120
Ω connected to the terminals marked
Term
.
Recommended line cable: Type A according to standard
ČSN EN 61158-2 (a twisted pair of
conductors, shielding on 90% area).
If the communication line is short and is to be used for the purposes of parameter setting prior to
the meter on-site installation, it is not necessary that the cable meet the requirements of standard
ČSN EN 61158-2, and no line termination resistor needs be used.
The control PC shall be connected to the communication line by means of a USB/RS-485 convertor.
The USB/RS-485 convertor including the connecting cables can be supplied on request.
Connect the flowmeter to its power supply grid.
Turn on the PC and find the USB input to which the communication line is connected (using the PS
equipment administrator function).
Run program FLOSET 4.0, select and open the *.flo file associated with the given flowmeter type.
