1 Bus specific parameters
Bus specific parameters 1
The following settings for the serial communication between the
PROFIBUS-DP master and the PROFIBUS-DP slave of the SIPROTEC
device have to be defined when programming the device.
Slave address The PROFIBUS-DP slave address of the SIPROTEC device is set using
the parameterization system DIGSI. Permissible slave addresses are in
the range between 1 and 126.
Baud rate The PROFIBUS-DP slave of the SIPROTEC devices can communicate
in a PROFIBUS-DP net with one of the following baud rates:
9.6; 19.2; 93.75; 187.5; 500, 1500; 3000 and 6000 kB/s.
Note
•At use of a SIPROTEC device with a PSO module the maximum
baud rate is 1500 kB/s (ref. to chap. 7.2).
•The PROFIBUS-DP slave of the SIPROTEC devices supports
automatic baud rate recognition.

Configuration data The DDB file characterises the SIPROTEC communication module as a
“slave with modular design“, i.e. depending on the selected mapping, the
number of input and output data is modified without changing the DDB
file.
The configuration data to the various devices are contained in the
corresponding bus mapping documents (ref. to page i).

2 Execution of switching operations via PROFIBUS-DP
Execution of switching
operations via PROFIBUS-DP 2
2.1 Command output modes
The following types of commands are available in the SIPROTEC
device:
Double commands Execution of the double commands, output to the switching devices and
checkback signal are processed through two outputs respectively two
bits, which are defined by “01“ = OFF and “10“ = ON.
Single commands Execution of the single commands, output to the switching devices and
checkback signal are processed by one output respectively one bit,
which is defined by “0“ = OFF and “1“ = ON.
Note
In deviation to the above-written definition, control of the single and
double commands in the SIPROTEC device via PROFIBUS-DP is
processed identically via two bits of the PROFIBUS-DP output
message.
A command output in the SIPROTEC device can be executed as conti-
nuous output or pulse output.
Commands with
continuous output Commands in the operation mode continuous output are executed
(controlled), if in the corresponding pair of bits a value changeover (a
slope) is recognized via PROFIBUS-DP from “quiescent status“ or OFF
to ON and they remain active until a new value changeover occurs from
“quiescent status“ or ON to OFF via PROFIBUS-DP.

Note
For the definition of the values for “quiescent status“, ON and OFF ref. to
chap. 5.2 and 5.3.
Commands with
pulse output Output of a control pulse to switch a switching device incl. monitoring the
programmed times is executed autonomously by the SIPROTEC device.
The switching operation (the pulse output via the allocated binary
outputs of the SIPROTEC device) is executed, if in the PROFIBUS-DP
output message the value of the corresponding pair of bits is changed
•from “quiescent status“ or ON to OFF or from “quiescent status“ or
OFF to ON controlling double commands,
•from "quiescent status" to ON controlling single commands.
For controlling switching devices it is preferred to use pulse outputs, for
which a number of parameters (e.g. output duration, overtravel time,
checkback supervision time) have to be set using the parameterization
software DIGSI.
Note
The switching direction OFF for single commands with pulse output is
not permitted and is rejected in the SIPROTEC device.

2.2 Behaviour under special operating conditions
•A change of the switching device status which was not initiated by
the PROFIBUS-DP master (e.g. circuit breaker trip) is recognized by
the PROFIBUS-DP master by a change of the value of the switching
device status in the corresponding bit positions of the input
message. If the PROFIBUS-DP master wants to reclose the locally
switched off switching device, then the current value (OFF) or
“quiescent status“ must first be transmitted via PROFIBUS-DP and
then the switching device can be reclosed by setting the must-value
to ON.
•A switching operation requested via PROFIBUS-DP which cannot be
executed (e.g. because the control authority is set to LOCAL or the
corresponding interlock conditions in the bay are not fulfilled), is
recognized by the PROFIBUS-DP master from a discrepancy
between the checkback signal of the double command or the status
of the single command in the PROFIBUS-DP input message and the
requested switching status (a checkback supervision time may be
activated in the PROFIBUS-DP master). Before starting a new
switching attempt, first the current switching status as per the input
message or “quiescent status“ has to be transmitted again in the
output message via PROFIBUS-DP.
•The response in the event of disturbed communication is described
in chap. 3.

3 Response in the event of disturbed communication to the PROFIBUS-DP master
Response in the event of
disturbed communication to
the PROFIBUS-DP master 3
The following response is defined for the SIPROTEC devices:
After detecting
the interrupted
connection to the
PROFIBUS-DP
master
1. The tagging SYSINTERR (Error Systeminterface) in the SIPROTEC
device is set to ON (registration in the operations event log,
processing in CFC is possible).
2. The status of the outputs and switching devices remains the same,
as they were before the interruption of the communication.
After
reestablishing
the
communication
1. The tagging SYSINTERR (Error Systeminterface) in the SIPROTEC
device is set to OFF (registration in the operations event log,
processing in CFC is possible).
2. The data from the messages which are now again received by the
PROFIBUS-DP master are registered (if this is possible according to
the control authority status).
If the switching device status of the SIPROTEC devices shall not be
changed after reestablishing the communication between PROFIBUS-
DP master and slave, then “quiescent status“ (value “00“) has to be
transmitted in the output message’s corresponding bit positions or the
control authority has to be set to LOCAL.

4 Annunciations to the PROFIBUS-DP master
Annunciations to the
PROFIBUS-DP master 4
Note
When analysing the annunciations of the SIPROTEC device in the
PROFIBUS-DP master, it should be noted that due to the cycle period of
the PROFIBUS-DP system or due to the cyclic processing time of a
PLC, temporary changes of an annunciation’s value (ON and OFF within
one cycle) may eventually not be recognized.
This applies in the first place for protection annunciations.
Protection pickup Protection annunciations which indicate the status protection pickup, are
active only for the period of time of the protection pickup.
Protection TRIP The parameter MINIMUM DURATION OF TRIP COMMAND (parameter
address = 210) allows setting of the minimum duration of the TRIP
command.
This time setting applies to all protection functions which may cause a
TRIP signal. After a protection TRIP, the corresponding protection
annunciations transmit the value ON for the programmed minimum time
duration.

Data type definitions 5
Following data types are used for storage of variables in PROFIBUS-DP
messages:
•Single-point indications
•Single commands
•Double-point indications
•Double commands
•Measured values (signed integer)
•Metered measurands (unsigned long)
Note
The storage of variables of more complex data types (measured values,
metered measurands) in the PROFIBUS-DP messages is processed
according to the following convention:
The octet with the most significant byte (MSB) of the variable is
transmitted prior to the octet with the least significant byte (LSB).
