Chapter 1 - Introduction
Thismanualdescribesthe SBI-PDP-33optional cardforconnectingofinverters
to Profibus-DP networks.
Drives belonging toARTDrive series can be connected in network through the
SBI-PDP-33 card.
This manual is intended for design engineeres and technicians responsible
for the maintenance, commissioning and operation of Profibus-DP systems.A
basic knowledge of Profibus-DP is assumed and may be found in the “Draft
Standard DIN 19245 Part 3” manual.

1.2 Overview of Profibus-DP
Profibus-DPis afield Bus designed fora fast data exchange relating to sensors
/ actuators level; the communication is established between a Master central
unit (PLC or PC) and Slave units, i.e. sensors, actuators, drives, etc.
The data exchange is cyclic; the Master unit reads the Slaves input data and
writes the Slaves output data. The Bus cycle time is shorter than the cycle time
of the central unit; the Baud Rates for the SBI card are from 9,6 kbit/s to 12
Mbit/s according to Profibus-DP standard part. 3.
The total cycle time depends on the number of Slaves connected; the 1.5-
Mbit/s Baud Rate allows 8 GEFRAN-SIEI drives to be polled in 6 milliseconds.
The physical support is the RS485 serial line; the max. number of Slaves
connected to the Bus is 127.
Example of Mono-Master Profibus-DP system.

2.2 Mounting
The SBI card is supplied with standoffs, screws, washers and a SBI-Drive link
cable provided with connectors.
1. Switch the drive off.
2. If the card is inside the drive mounted (see example below), fasten the
SBIcardtothedrive regulation board by means of screws (B) and standoffs
(A). The SBI-Drive link cable (C) must be connected between XT1 (on
Regulation board) and XT (on SBI card).
If the card is mounted outside the drive, the SBI card has to be fastened
to a DIN rail by using the external mounting kit; it is recommended to keep
the SBI card as close as possible to the drive. Do not put the SBI-Drive
link cable near power cables.

—————— Profibus -DP Interface card ——————
3. The SBI-Drive link cable is connected to the XT connector on the SBI-
card.
4. The bus terminating resistors are connected or disconnected through the
S2 dip switch.
The last physical card in network shall have such resistors connected in
case the connector in use should not contain terminating resistors itself.
ON = connected
OFF = disconnected.
5. The S1 dip switch determines the Slave address.
The addresses “0” and “1” are reserved to the Master and can not be
used. The switch S1-8 is not significant for the address and must always
be set to OFF. The address is only detected when the card is switched
on. If the address has been modified, the Profibus-DP interface card has
first to be switched off and then on in order assume the new address.
6. Connect the Bus cable to XS1 or XS2 connectors.
7. Switch on the drive.
8. The LEDs +5V and +5VE light up.
9. The LED DEA lights up when the communication enters in the Data
Exchange Phase.
2.3 Power Supply
Thepowersupplyisprovidedby the XT connector which is also used to transfer
data between the SBI card and the drive regulation card.
Current draw: 350 mA
2.4 LEDs
+5V +5V power supply.
RST Reset active.
DEA Data Exchange Phase active.
+5VE +5V power supply on the RS 485 driver side galvanic isolated.
2.5 Technical Specification
Storage temperature: -20°... +70°C (-68...+158°F)
Operating temperature: 0°... +55°C (32...+131°F)
These temperatures are adequate to those of the drive, to which the cards are
connected.

2.6 Interface
For the mechanical connection, according to the internal or external mounting,
please use the kit and the mounting instruction sheet supplied with the card.
Fortheelectricalconnectionplease use the SBI-Drive link cable, also supplied.
For the connection to the Bus please use a shielded twisted cable
recommended by Profibus specification.

Chapter 3 - Bytes Assignment for Data Exchange
The SBI card uses a 16 or 20 byte frame. The first 8 bytes represent the
configuration channel for the acyclic data exchange, the other are the process
data channel for the cyclic exchange.
The bytes assignment is as follows:
Configuration channel Process data channel
WORD 0
01234567
Data / error
Subindex / Type
Index
Control byte
WORD 2 WORD 3 WORD 4 WORD 5WORD 1
As to the Data/Error and Index fields, the data format is arranged from the
least to the most significant byte. The meaning of the fields is the following:
A ) Data frame from Master to Slave:
1 ) Data / Error
The content of this field depends on the kind of service carried out: in case
of writing it contains the parameter value, in case of reading it has no
meaning.
2 ) Subindex/Type
It contains the parameter subindex, if any. If the parameter has no
subindexes it has to be set to 0. For parameters with subindex, this has to
be set from 1 to the max. number of parameter elements; the value 0 is
not accepted and rejected. It is not possible to read the whole object, but
onlyitssingleelements.Incaseofservicecarriedouttowards theAPC100y
option, this field should contain the data type (see APC100y manual).
3 ) Index
Index of the parameter involved in the operation with format low byte -
high byte.
4 ) Control byte
The meaning of this byte is described in 3.1.
B ) Data frame from Slave to Master:
1 ) Data / Error

The content of this field depends on the kind of service carried out. In
caseofwritingit containstheoperation result. In case of reading itcontains
the parameter value if the reading had positive result; if not, it contains the
detailed error code. As to the error codes and operation result, please
refer to drive manual).
2 ) Subindex/Type
It contains the parameter subindex, if any. If the parameter has no
subindexes it has to be set to 0. For parameters with subindex, this must
be set from 1 to the max. number of parameter elements; the value 0 is
not accepted and rejected. It is not possible to read the whole object, but
onlyitssingle elements. In case of service carried out towardstheAPC100y
option, this field contains the data type (see APC100y manual).
3 ) Index
Index of the parameter involved in the operation with format low byte -
high byte.
4 ) Control byte
The meaning of this byte is described in 3.1.
Incaseof service towardsAPC100yoption, please refer totheAPC100ymanual
for error codes.
