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:
