Gateway InterBus-S
For communication on the PROFIBUS-DP,
there is a choice between PPO Types 1
(Process data and parameter interface) or
PPO Types 3 (process data only). Process
data is handled as I/Os, i.e. it is available
for the user in the I/O-area of the PLC and
is transmitted with
every InterBus-S-cycle.
Parameterization of the VLT®via the para-
meter interface is effected via PCP Com-
munication.
Overview
Overview
The purpose of the InterBus-S /
PROFIBUS-DP-Gateway is to enable the
Danfoss VLT®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-Telegrams,
which are then transmitted to the VLT®.
Reporting back occurs in the same way.
The Gateway converts the PROFIBUS-
DP-Telegrams from the VLT®, which are
then tranmitted to the master via the
InterBus-S.
■The Gateway enables connection of up to
14 VLT®5000 with a PROFIBUS Option
Card. The Gateway sends continuous in-
formation of the selected PPO Type with
the actual process 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
remote bus participant. However, this
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,
ready-made bus wire, maximum extension
8 metres, etc., no longer apply.

Properties 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 error
report.
The InterBus-S in-/output data is
projected on the PROFIBUS-DP without
any interpretation being offered. With one
exception, bit 10 of the control word
(CW), is inverted. This ensures that when
the PLC moves to Stop and resets all
outputs, the connected VLTs will stop,
too; also, when the InterBus-S
communication starts, it is ensured that
the VLT®5000 remain stopped.
Properties of PROFIBUS-DP-Page
■The PPO Type1 allows parameterization of
the VLTs, retrieval of all values and para-
meters - including fault and diagnostic
data, as well as control of the VLT®with
reporting back on its actual state.
The PPO Type3, on the other hand, allows
only control and reporting back on the
state of the VLT®.
With respect to the functioning and hand-
ling of the parameter interface in PPO
Type1, please refer to the manual on
PROFIBUS Option Cards for VLT®5000.
The baudrate on the PROFIBUS-DP is
1.5Mbaud, which means that the
maximum bus cable length is 100 m.
Further information is available from the
PROFIBUS manual for VLT®5000.
!!! IMPORTANT !!!
Before inserting the PROFIBUS Option Card, the VLT®should be turned 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
initialization is effected 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 already
been inserted, the keys DISPLAY/STATUS + MENU + OK must be pressed
simultaneously before turning on the VLT®; subsequently, turn on the power and
keep the three keys pressed until the message "Manual Initialize" appears in the
bottom line of the display window (see page 136 in MG.50.AX.02).

descriped in the PROFIBUS manual for
VLT®5000.
Parameter 918
Station address,
this is where the station address is
selected. The range of operation of the
Gateway is from 1-14, with attention
having to be given to throughgoing
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 where to select whether the para-
meter can be altered via the BUS,

Parameterization
Parameterization via the Bus is only
possible if using PPO Type1.
Parameterization is effected via PCP
Communication. The procedure is as
follows:
Order to Report from
IBS-master: VLT®to master:
Write.Request Confirmation
positive
Confirmation
negative, reporting
of error code
Read.Request Confirmation
positive includes
the data of the
requested parame-
ter of the VLT®
Confirmation
negative, reporting
of error code
Notes concerning programming:
The frequency converter can now be con-
trolled via the BUS; this is effected simply
through setting or reading of I/O-Bits.
Control word
As opposed to what is said in the product
manual about the PROFIBUS Option
Card, bit number 10 has to be set at "0"
to enable control. This will ensure that the
VLT®accepts the control word. The
Gateway automatically converts this bit to
a "1".
The control word for:

Reference/Actual values
The reference and the actual value of the
VLT®returned are handled in a norm-set
format. The setting range goes from
-10000 for -100.00% up to +10000 for
+100.00%. The 100.00% corresponds to
4000 hex. Negative reference are
generated through the two's complement.
Example:
Min.frequency = 0Hz;
Max.frequency = 50Hz
Desired is 25Hz corresponding to 50% of
the max. rpm:
50.00% = 2000 hex =
0010 0000 0000 0000Binary
For 25Hz with reversing = -50% of the
max. rpm:
50.00% = 2000 hex =
0010 0000 0000 0000Binary
reversal of a positive to a negative desired
value:
00100000 0000 0000 Binary
-> 1101 11111111 1111 Binary One's complement
-> + 1 Binary
= 1110 00000000 0000 Binary Two's complement
-50.00% = E000 hex = 1110 0000 0000 0000Binary

Parameter interface in
Write.Request
The parameter interface (PCV) of the VLT®
5000 contains a total of 4 words. This
enables reading and writing of parame-
ters, 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
the parameter number, in the upper four
bits (bits 12..15) select the desired action.
2. Word (Index/Subindex, IND); the byte
"Index" is only used if wanting to use
elements of an array. In 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.
3. + 4. Word (Parameter Value, PVA); in
the case of write action, this is where the
value of the selected parameter is ente-
red. The third word is the High-Word; the
fourth word is the Low-Word. The third
word is only used if parameter values
above 65535 are to be transmitted.
Since values are not transmitted in
comma format, each parameter value
must be multiplied by a factor. The para-
meter factor in each case can be seen
from the manual for the PROFIBUS Option
Card.
Example:
In VLT®5000, with bus address 2, the
parameter 202 maximum frequency is to
be changed to 80 Hz,
PCA: 20CA
Parameter CA hex = 202
Action 2 = Change parameter value
IND:0000
no Subindex
no Index
PVA: 0000 0320
Parameter value_low =
320 hex = 800 = 80.0 x Factor 10
Parameter value_high = 0

Responses from the VLT®to an order
initiated previosly via Write.Request. Data
is only available in the case of a positive
confirmation; if there is a negative
confirmation, an error code is reported.
1. Word (Parameter-Identification-Value,
PCA); in the lower 11 bits (bits 0..10) the
VLT®enters the parameter number; in the
upper four bits (bits 12..15) the type of
response appears.
2. Word (Index/Subindex, IND); the byte
"Index" is only entered if elements of an
array have been accessed. In normal pa-
rameter actions, this byte is not used. The
byte subindex is intended for subsequent
extensions and is not used at this point.
■
Properties of PROFIBUS-DP
Now the length of the data has to be
entered; since, however, this is only pre-
pared for the maximum layout, a length of
112 bytes has to be entered here. Now
follows the data of the VLTs, in the se-
quence of their addresses.
3. + 4. Word (Parameter value, PVA); this
is where the VLT®enters the value of the
selected parameter. The third word is the
High-Word; the fourth word is the Low-
Word. The third word is only used if para-
meter values above 65535 have been
transmitted.
Since the values to be transmitted are not
transmitted in comma format, the indivi-
dual parameter value must be divided by a
factor to obtain the actual value. The indi-
vidual parameter factor can be seen in 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, there 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 concerning
the PCP Communication please see the
manual for the InterBus-S-Master.
All start-up components first branch into
FB210, which carries out the configu-
ration of the InterBus-S-Master assembly.
