About this manual

This manual is intended as both an instruction ma-
nual and a reference guide. It only broaches the
basics of the PROFIBUS DP protocol, and only
when it is necessary to provide a sufficient under-
standing of the PROFIDRIVE implementation of
the PROFIBUS profile for variable speed drives
(version 2, PNO) and of the PROFIBUS option card
for the series VLT 5000/VLT 5000 Flux/VLT 6000
HVAC/VLT 8000 AQUA by DANFOSS.
In addition, the manual is intended to serve as a
guidebook for the specification and optimization of
the existing communication system.
It is suggested that readers who are not completely
familiar with PROFIBUS DP or the profile for varia-
ble speed drives review the relevant literature on
these subjects.
Even experienced PROFIBUS programmers should
read the entire manual prior to programming, since
every chapter of the manual contains important
information.
Chapter 2 deals with the quick start of the com-
munication parameters for the DP communication.
Chapter 3 contains details regarding the
PROFIBUS option card and the establishment of
the physical connection.
Please refer to chapter 4 for information regarding
the time behaviour.
Chapter 5 presents an overview of the PPOs (infor-
mative data telegrams).
The PCA interface as a parameter interface in the
PPO is explained in chapter 6.
Chapter 7 contains the description of the parame-
ter and data structure.
Chapter 8 contains a description of spontaneous
messages.
The response to the "Sync" and "Freeze"
commands is explained in chapter 9.
The control word and status word as essential
elements of the PPOs for the operational control,
as well as the bus reference value are explained in
chapter 11.

VLT ® 5000/5000 Flux/6000 HVAC/8000 AQUA PROFIBUS
Chapter 12 contains examples for the use of the
PPOs. It is recommended that readers review the
examples for a better understanding of the PPOs.
Comments regarding the GSD file can be found in
chapter 13.
Chapter 14 contains the VLT parameters specific to
the Profibus.
Warning and alarm messages and display readings
specific to the Profibus are described in chap-
ter 15.
A parameter listing as an overview of all VLT 5000/
VLT 5000 Flux/VLT 6000 HVAC/VLT 8000 AQUA
parameters can be found in chapter 16.
In chapter 17 you will find the abbreviations used
in this manual. The manual concludes with a short
glossary and a detailed index for quick navigation.
If you are interested in learning more about the
PROFIBUS protocol in general, we recommend
that you consult the relevant, very comprehensive
literature for this purpose.

Assumptions

The manual assumes that you are using a
DANFOSS PROFIBUS option card with field bus,
together with a DANFOSS
that you are using a PLC or a PC with a serial
interface as master which supports all
communication services for PROFIBUS, and that
all requirements are met and all limitations are
observed which arise from the PROFIBUS stan-
dard, the PROFIBUS profile of variable speed dri-
ves, and the company-specific implementation of
PROFIDRIVE, or those of the VLT drives.

Background knowledge

The DANFOSS PROFIBUS option card is designed
for the communication with all masters that comply
with the PROFIBUS standard. Thus, the assump-
tion is made that you are familiar with the PC or
PLC to be used as a master on your system. Any
questions regarding the hardware or software of
other suppliers are beyond the scope of this ma-
nual and outside the responsibility of DANFOSS.
In the event of questions concerning the configura-
tion of the master-to-master communication or the
configuration with a slave not manufactured by
DANFOSS, you should refer to the information in
the respective manuals.
