PC software and serial communication
Danfoss offers various options for serial communi-
cation. Using serial communication makes it possible
to monitor, programme and control one or several VLT
6000 HVAC from a centrally placed computer. For
example, Danfoss offers an option card for Profibus.
In addition, all VLT 6000 HVAC have an RS 485 port
as standard, which enables them to communicate
e.g. with a PC. A programme entitled VLT Software
Dialog is available for this purpose.
VLT Software Dialog comes in three modules and - as
a minimum - contains the programmes included in
the Basic module.
The Basic module covers:
TEST RUN
is used for controlling and commissioning of
a frequency converter, including:
- setting of reference value,
- simultaneous display of selected
parameters in graphs,
- option of DDE link, e.g. to a spreadsheet.
PARAMETER SETUP
is used for setting up and transferring para-
meter sets, including:
- setting of frequency converter parameters,
- parameter sets can be obtained from and
copied to a frequency converter,
- documentation/print-out of the Setup
including diagrams.
HISTORY
provides information about the different
stages of development of the VLT Software
dialogue.
BUS ADDRESS SETUP
is only used for addressing the VLT FCM.
The Logging module covers:
■
LOGGING
is used for collecting and displaying historical or
real-time operating data.
- graphical representation of selected
parameters from several frequency
converters,
- collection of log data to file,
- option of DDE link e.g. to a spreadsheet.
MODEM SETUP
is used for setting up the frequency converter
modem.
- sets the frequency converter modem via the
communication port of the PC.
The template module covers:
TEMPLATE SETUP
is used for setting up template files for
PARAMETER SETUP:
- the template file functions as a mask that
limits the number of accessible parameters
when a parameter file is to be made or edited
in PARAMETER SETUP,
- the template file may contain preset values for
the parameters of the frequency converter.
NB!
The logging and template module calls for a
Basic module to be installed on the same PC.
The guided tour covers:
GUIDED TOUR
offers a demonstration of the VLT
