2800 Series
Introduction to VLT
2800
The protocol standard is based on an RS 485
bus system with a maximum transmission speed
of 9600 baud. The following Drive profiles
are supported as standard:
- FC D rive, which is a profile adapted to Danfoss.
- Profidrive, which supports the profidrive profile.
See Serial communication for further details of
telegram structure and Driv e profile.
■ Fieldbus option
The increasing information requirements in industry
make it nece ssary to collect or visualize many different
process data. Important process data help the system
technician with the daily monitoring of the system. The
large amounts o f data involved in major systems make
a higher transmission speed than 9600 baud desirable.
Fieldbus option
Profibus
Profibus is a fieldbus system, which can be used
for linking automation devices such as sensors
and actuators with the controls by means of
a two-conductor cable. Profibus DP is a very
fast communication protocol, made specially for
communication between the automation system
and v arious types of equipment.
Profibus is a re gistered trade mark.
DeviceNet
DeviceNet fieldbus systems can be used for linking
automation devices such as sensors and actuators with
the controls by means of a four-wire conductor cable.
DeviceNet is a medium speed c ommunication protocol,
made specially for communication between the
automation system and various types of equipment.
Units with DeviceNet protocol cannot be controlled
by FC protocol and Profidrive protocol.
VLT Software Dialog can be used on the Sub D plug.
■ Modbus RTU
MODBUS RTU (Remote Terminal Unit) Protocol is
a m essaging structure developed by Modicon in
1979, used to establish master-slave/client-server
communication between intelligent devices.
MODBUS is used to monitor and program
devices; to communicate intelligent devices
with sensors and instruments; to monitor field
devicesusingPCsandHMIs.
MODBU S is often applied in Gas and Oil appl ications,
but also in build ing, infrastructure, transportation and
energy, applications are m aking use of its benefits.
