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.

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

—————— SBI-PDP-33 ——————

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

The status bit is only used by the Slave, therefore it has a meaning only during
the transmission from Slave to Master; in the transmisson from Master to Sla-
ve it has always to be set to 0.
3.2 Meaning of Handshake
The Handshake bit prevents the same service request from being carried out
more than once and its function is the same both in the direction from Master
toSlaveand from Slave to Master.Theexplanationbelow refers to the direction
Master to Slave, but the same considerations may be applied for the opposite
direction.
The default value of this Bit is 0. Every time that a transition of this Bit occurs,
both from 0 to 1 (positive edge) and from 1 to 0 (negative edge), the Slave
carries out the service requested by the Master through the data frame
previously set. Therefore, this Bit acts as a Trigger, through which the Master

—————— SBI-PDP-33 ——————
12
indicates the Slave that the data for the requested service are ready.
The Slave responds to the Master in the same way, by causing a Handshake
Bit transition (both positive or negative).
Consequently, the Master is able to send a service on the Bus only if its
Handshake Bit is equal to the one received by the Slave.
During the initialization and in case the Master does not receive the Slave
response within a Timeout of 500 mSec, the Master shall send a no-request
service (all Bits are set to 0), thus allowing the Slave to perform a
communication Reset. This causes the reset of the Slave Handshake Bit.
The Timeout for the service towards the APC100y option shall be longer (1.5
sec). The Master should therefore have two different Timeouts: one for the
services towards the drive and one for those towards the APC100y option.

Chapter 4 - Process Data Channel Control
This function allows the assignment of the drive parameter to the Process
Data Channel Words.
The SBI card uses 4 or 6 words (WORD) for the Process Data Channel (abbr.
PDC Process Data Channel ).
The Process Data Channel for the SBI-PDP-33 card has the following
configuration
WORD 0 WORD 2 WORD 3 WORD 4 WORD 5WORD 1
The Slave can both read and write Process Data Channel data.
The data read from Profibus-DP by the Slave are referred to as input data; the
data written in Profibus-DP by the Slave are referred to as output data.
The Slave parameters are cyclically read by the Master by assigning drive
parameters to the PDC output configuration parameters.
The Master cyclically transmits drive parameters to the Slave by assigning
drive parameters to the PDC input configuration parameters.

Chapter 5 - Alarms
5.1 Profibus-DP Alarms
The alarms indicated to the drive by the SBI card are the following:
1 - Bus loss: if an accidental interruption of the connection occurs, this alarm
is generated.
2 - SBI Hardware Fault: if the SBI card is faulted, this alarm is generated.
The alarm handling carried out by the drive depends on the drive itself and
how the alarms are configured.
If the Master is switched off before the Slave, the Bus-Loss alarm occurs; the
drive handles this event by not storing the alarm in order to avoid having the
alarm annunciated when the drive is next switched on.
The communication between Master and Slave can only be carried out if the
initialization of the drive and of the SBI card is successfully terminated; if not,
it is not possible to determine the cause of the erroneous initialization using
the Bus.
5.2 Drive Alarms Handling
The drive reports automatically its status to the SBI card, if an alarm condition
occurs.
When the communication is established, the drive status is sent to the Master
in at the moment in which the drive initialization has terminated.
Every time the Drive changes its status, the SBI card sends the updated drive
status to the Master by means of a diagnostic message ( please refer to “Draft
Standard DIN 19245 Part 3” sect. 8.3.1 ).
The information are contained in the ‘User Specific Diagnostic Data’ field of
the diagnostic message.
This field is made up of three Bytes. The first contains the ‘User Specific
Diagnostic Data Length (in bytes)’and is set to three. The second and the third
contains the code of the drive status (for the code please refer to the drive
manual). When a drive alarm occurs, also the ‘Ext_Diag’ bit in the first Byte of
the ‘Diagnostic Data’ is set to 1.

As for the digital terminals, before operating the virtual digital I/O, drive
parameters must be assigned to the single terminal; in order to do this, please
refer to the drive manual.
DigitalI/O value can be cyclically and fast transferred throughthePDC channel,
in order to do this, the virtual digit I/O value parameter must be assigned to
one of the PDC words.
Above picture shows that the virtual digital input has been assigned to the
PDC Input Word 0. The example reports also some drive signal assigned to
the virtual digital input.
For virtual digital I/O configuration, please refer to the “OPTION 1” chapter of
the drive instruction manual.
