Overview
The purpose of the InterBus-S /
PROFIBUS-DP-Gateway is to enable the

®

Danfoss VLT

Overview

5000 Frequency Converter
to be operated with the Field Bus system
InterBus-S. For this purpose, the
Gateway converts the InterBus-S
Telegrams to PROFIBUS-DP-T elegrams,
which are then transmitted to the VLT

Reporting back occurs in the same way.
The Gateway converts the PROFIBUS-

®

DP-T elegrams from the VLT

, which are
then tranmitted to the master via the
InterBus-S.

Gateway InterBus-S

The Gateway enables connection of up to

®

5000 with a PROFIBUS Option

14 VLT
Card. The Gateway sends continuous in­formation of the selected PPO Type with
the actual pr ocess data block and the
actual parameter block to the VLTs .

®

.

As is usual with InterBus-S, connection of
the Gateway occurs in the form of a
r emote bus participant. However, t hi s
does not convert to the InterBus-S Local
Bus, but to PROFIBUS-DP. This also
means that the well-known limitations of
the local buses, such as max. 8 nodes,
r eady-made bus wire, maximum extension
8 metres, etc., no longer apply.

For communication on the PROFIBUS-DP,
ther e is a choice between PPO Types 1
( P rocess data and parameter interface) or
PPO T ypes 3 (process data only). Process
data is handled as I/Os, i.e. it is available
for the user in the I/O-ar ea of the PLC and
is transmitted with

2

every InterBus-S-cycle.

®

Parameterization of the VLT

via the para­meter interface is ef fected via PCP Com­munication.

P roperties of the PROFIBUS-DP

A maximum of 14 VLTs can be linked up ­using the PPO Type1 (12Byte) or the PPO
Type3 (4Byte). The selection of PPO Type
goes for all VLTs; mixed operation is not
permissible and will lead to an err or
report.
The InterBus-S in-/output data is
p r ojected on the PROFIBUS-DP without
any interpr etation being of f ered. W ith one
exception, bit 10 of the contr ol wor d
(CW), is inverted. This ensur es that when
the PLC moves to Stop and resets all
outputs, the connected VLT s will stop,
too; also, when the InterBus-S
communication starts, it is ensur ed that

®

the VLT

5000 remain stopped.

Gateway InterBus-S

The PPO Type1 allows parameterization of
the VLTs , r etrieval of all values and para­meters - including fault and diagnostic
data, as well as contr ol of the VLT
reporting back on its actual state.
The PPO Type3, on the other hand, allows
only control and r eporting back on the

®

state of the VLT

.
With respect to the functioning and hand­ling of the parameter interface in PPO
Type1, please r efer to the manual on
PROFIBUS Option Card s for VLT
The baudrate on the PROFIBUS-DP is

1.5Mbaud, which means that the
maximum bus cable length is 100 m.

!!! IMPORTANT !!!

Before inserting the PROFIBUS Option Car d, the VLT® should be tur ned on and
parameter 620 should be set to "Initialize". Subsequently, remove the power and
insert the PROFIBUS Option Card. When the unit is turned back on, new
i ni ti al iz at io n is e ffected automatically. Be aware that all parameters will be set to
Factory setting!
If this sequence is not possible, or if the PROFIBUS Option Card has alr eady
been inserted, the keys DISPLAY/STATUS + MENU + OK must be pressed
simultaneously before tur ning on the VLT
keep the three keys pr essed until the message "Manual Initialize" appears in the
bottom line of the display window (see page 136 in MG.50.AX.02).

Configuration of the frequency
converter

The following parameters are to be set
or checked, respectively:

Parameter 502-508
Motor coasting, quick-stop, DC­braking, start, reversing, reset, setup
selection, selection of digital refe­r ence,
this is wher e to decide if contr ol is going
to be via "BUS" only or via "Digital In-

put" only, or via a combination of the
two. In the case of BUS-selection only,
all parameters should be set to "BUS" at
this point.

Parameter 512
Telegram profile
this is wher e to select the telegram Pr of ­il e, the profiles ar e descriped in the
PROFIBUS manual for VLT

Danfoss recommend to use Danfoss
profile.

Parameter 801
Baudrate
enter the Bus-Baudrate selected for your
Gateway, or leave the rate at "1.5
MBAUD". At present, the Gateway
baudrate has been set at a fixed rate of

1.5Mbaud.

Parameter 800
FMS/DP-selection,
this is wher e to set "DP"; This is the
factory setting.

Parameter 803
Bus time out,
this time selection determines the delay

The parameters set on the VLT
are not activated until the
power supply has been cut off
and re-cycled.

after a BUS drop-out befor e a r eaction
fr om the fr equency converter is to ensue.

Parameter 804
Bus time out function,
select the r eaction after a BUS drop-out.

Parameter 904
PPO select,
enter the telegram desired, e.g. for PPO
Type1 enter "PPO type1", for PPO Type3
enter "PPO Type3". The PPO types ar e
descriped in the PROFIBUS manual for

®

VLT

5000.

Parameter 918
Station address,
this is wher e the station addr ess is
selected. The range of operation of the
Gateway is from 1-14, with attention
having to be given to thr oughgoing
addressing. The address range basically
begins at "1" and ends at the address of
the maximum number of units available.
This physical position at the BUS has no
influence on addressing.

Parameter 927
Access to parameter change,
this is wher e to select whether the para­meter can be altered via the BUS,
("Enable"), or whether this possibility is to
be disabled ("Disable") .

Parameter 928
to p rocess contro l ,
like 927, although this is wher e i t i s t o b e
decided whether control i s going to be ef­fected via the PROFIBUS ("Enable") o r
not ("Disable" ).

®

All other parameters are to be set in
accordance with the intended application,
as described in the product manual.

Notes concerning programming:

■

The fr equency converter can now be con­trolled via the BUS; this is ef fected simply
t h r ough setting or r eading of I/O-Bits.

Control w ord

■

As opposed to what is said in the product
manual about the PROFIBUS Option
Car d, bit number 10 has to be set at "0"
to enable control. This will ensur e that the

®

VLT

accepts the control word. The
Gateway automatically converts this bit to
a "1".

The control wo r d f o r:
starting forwar d is
047F Hex or 0000 0010 0111 1111.
starting r everse is
847F Hex or 0100 0100 0111 1111.
stopping with normal ramp (Param. 208) is
044F Hex or 0000 0100 0100 1111,
stopping with alter native ramp (Param.

210) is 064F Hex or 0000 0110 0100

1111.

■

Reference/Actual values

The r efe rence and the actual value of the

®

VLT

r etur ned are handled in a norm-set
format. The setting range goes fro m

-10000 for -100.00% up to +10000 for
+100.00%. The 100.00% corresponds to
4000 hex. Negative re fe r ence ar e
generated through the two's complement.

Example:
Min.fr equency = 0Hz;
Max.frequency = 50Hz
Desir ed is 25Hz corr esponding to 50% of
the max. rpm:

50.00% = 2000 hex =
0010 0000 0000 0000Binary

Gateway InterBus-S

For 25Hz with reversing = -50% of the
max. rpm:

50.00% = 2000 hex =
0010 0000 0000 0000Binary
reversal of a positive to a negative desir ed
value:

0010 0000 0000 0000 Binary

-> 1101 1111 1111 1111 Binary One's complement

->+ 1 Binary
= 1110 0000 0000 0000 Binary Two's complement

-50.00% = E000 hex = 1110 0000 0000 0000Binary

Parameter interface in
W rite.Request

The parameter interface (PCV) of the VLT
5000 contains a total of 4 words. This
enables r eading and writing of parame­t e r s, reading of arrays, writing, etc.

The parameter interface can be detailed
as follows:

1. Word (Parameter -Identification-Value,
PCA); in the lower 11 bits (bits 0..10) enter

P roperties of PROFIBUS-DP

the parameter number, i n the upper four
bits (bits 12..15) select the desir ed action.

2. Word (Index/Subindex, IND); the byte
"Index" is only used if wanting to use
elements of an array. I n this case, enter
the index of the element in question. In
normal parameter actions, this byte is not
used. The byte subindex is intended for
subsequent extensions and is not used at
this point.

the case of write action, this is where the
value of the selected parameter is ente­r ed. The thir d word is the High-Wo r d; the
fourth word is the Low-Wor d. The thir d
wor d is only used if parameter values
above 65535 are to b e transmitted.
Since values are not transmitted in
comma format, each parameter value
must be multiplied by a factor. The para­meter factor in each case can be seen
from the manual for the PROFIBUS Option
Card .

Setting the PDU length in PCP

On the basis of the possibility of having 14
VLTs connected to the gateway, t h e re is a
need for an extended PDU length. The
following example shows how in the SPS
start-up the PDU length can be changed
in CRL. For further information concer ning
the PCP Communication please see the
manual for the InterBus-S-Master.
All start-up components first branch into
FB210, which carries out the configu­ration of the InterBus-S-Master assembly.
