1.1 Hardware requirements, Order options and Firmware compatibility
Two PROFIBUS communication modules are used for the redundant PROFIBUS DP
slave of the 6MD663 and 6MD664 devices.
These two modules are installed on port B and port D of the SIPROTEC device (ref.
to Figure 1-1).
Figure 1-1 Communication interfaces at the rear panel of a device with redundant PROFIBUS DP RS485
Note:
The functionality of the redundant PROFIBUS DP interface only is possible with
PROFIBUS communication modules from HW revision 4.
If devices with an already built-in PROFIBUS communication module HW revision 2
shallbe retrofitted with aredundant PROFIBUSDP interfacethen thisexistingmodule
also has to be replaced by a HW revision 4 module.
Additional information about the hardware releases of the communication modules
you find in the manual “SIPROTEC Communication module, PROFIBUS DP - Com-
munication profile”.

1.2 Redundancy concept
6MD663 and 6MD664 devices with redundant PROFIBUS DP interface are intended
for use in a PROFIBUS DP communication system with system redundancy.
The remarkable features of system redundancy are:
•Redundant PROFIBUS DP master devices.
•Redundant field bus lines.
•Bay controller with redundant PROFIBUS DP slave interfaces.
System

Figure 1-2 Components of a system-redundant communication system
During operation, one of the subsystems shown in Figure 1-2
•Master #A - Field bus #A - Slave interface #A or
•Master #B - Field bus #B - Slave interface #B
is in state PRIMARY (or process-controlling) whereas the other subsystem has the
state BACKUP (or standby).
PRIMARY The PRIMARY subsystem is the active one and has full access to the process.
Beside reading access, the PRIMARY master also can send output data to the bay
unit as well as to the process, e.g.:
•command outputs and set-point values,
•time synchronization of the slave devices by the master,
•acknowledgment of read event list entries.
All these information and commands are evaluated by the PRIMARY slave interface
and passed on to the bay unit or the process outputs.

BACKUP In the BACKUP subsystem, the master device behaves passive in process direction.
Only read access of process data is possible for the BACKUP master.
All data in the output messages are rejected by the BACKUP slave interface.
AMaster-Mastercommunication1serversfor comparison ofthe processimages inthe
master devices and for mutual supervision.
In case of a failure of components in the current PRIMARY subsystem, the BACKUP
system can take process control and become PRIMARY for its part (redundancy
switchover).
Redundant slave A redundant PROFIBUS DP slave(e.g. 6MD663 or 6MD664) which can be connected
to the system-redundant communication as shown in Figure 1-2 has the following
characteristics:
•The redundant slave consists of two independent PROFIBUS communication inter-
faces (which are redundant with respect to the protocol firmware and the hardware
interface).
•It exists an internal communication channel (independent from PROFIBUS)
between the two PROFIBUS communication interfaces of the redundant slave.
This communication channel is describedas RedCom subsequently and serves for
exchanging of status information as well as for mutual supervision.
•Both slave interfaces have identical PROFIBUS addresses.
•One of the both slave interfaces works as PRIMARY, the other as BACKUP.
Output data of the master device are only evaluated in PRIMARY state.
The decision if a slave interface can become PRIMARY depends on various factors:
•Communication status with the master device (“in data exchange” or “not con-
nected”).
•PRIMARY/BACKUP state of the master device.
The master device must inform the slave about its state via PROFIBUS communi-
cation. In the implementation of the redundant slave of the SIPROTEC devices a
byte in the data area of the cyclic data exchange message is used for that (ref. to
chap. 1.4.1.4).
•Operating status of the partner module (partner interface) in the redundant slave.
This contains both the current redundancy state (PRIMARY/BACKUP) and the
hardware state (“operational” or “error”).
RedCom communication is used to determine the state of the partner module.
The behavior of the redundant slave of the SIPROTEC devices in case of redundancy
start-up and redundancy switchover is described in chap. 1.6.

Also a superordinated control system can do this task.

1.3 Parameterization
1.3.1 DIGSI
1.3.1.1 Procedure
Prerequisites For the parameterization of a 6MD663 or 6MD664 with redundant PROFIBUS DP
have to be used:
•DIGSI 4.71 or higher,
•6MD663/4 PROFIBUS DP standard mapping 3-3 or 3-4
(with redundancy support, ref. to chap. 3 and 5 for data size)
Module selection Figure 1-3 shows the system interface selection when a new device with redundant
PROFIBUS DP RS485 (according to the device MLFB order number) is created in
DIGSI.
Changing the system interface in DIGSI to redundant PROFIBUS DP for already exist-
ing devices is also possible considering the prerequisites discussed in chap. 1.1.
Figure 1-3 Selection of PROFIBUS DP RS485 redundant as system interface
Mapping file and
allocation The parameterization of a redundant PROFIBUS DP system interface does not differ from the steps which must be executed for a non-redundant PROFIBUS DP system
interface. This includes the mapping file selection and the allocation of data objects as
“Source system interface” and “Destination system interface”.
Please ref. to the manual “SIPROTEC Communication module, PROFIBUS DP -
Communication profile”, chap. “PROFIBUS DP - Parameterization in DIGSI”, regard-
ing information about the mapping file selection and the allocation of data objects.
During the device start-up, the SIPROTEC device firmware ensures that in case of a
redundant PROFIBUS DP interface the parameter data (allocations and bus specific
parameters) are loaded onto the two PROFIBUS DP modules. Both PROFIBUS DP
interfaces of the redundant slave always have identical parameters with that.
The communication redundancy itself is transparent for the SIPROTEC device.
All redundancy tasks are carried out by the PROFIBUS DP modules using the PRI-
MARY/BACKUP principle (ref. to chap. 1.2).
Data from the device are transferred to both modules simultaneously.
Commands to the device come only from the module which has the PRIMARY state.

1.3.1.2 Bus specific parameters
The chap. “Bus specific parameters” in the manual “SIPROTEC Communication mod-
ule, PROFIBUS DP - Communication profile” describes the common settings for the
serial PROFIBUS DP communication.
In addition to this, further parameters are available if 6MD663/4 standard mapping
3-3 or 3-4 is selected.
PNO identification
number GlobalSection.DP_IdentNo
Here, the PNO identification number of the redundant PROFIBUS DP slave of the
SIPROTEC devices has to be entered: 0x8138.
This must correspond to the GSD file which is used for parameterization in the PROFI-
BUS DP master (ref. to chap. 1.3.3).
Float to integer
conversion for
measured values
GlobalSection.DP_CountersWithStatus
Beside the activation of the status bits for counters (ref. to “SIPROTEC Communica-
tion module, PROFIBUS DP - Communication profile”, chap. “Metered measurands”),
this parameter also determines how the measured values are converted from the
SIPROTEC internal float format to the integer format used for PROFIBUS DP.
The following table shows the valid values for this parameter.
Please ref. to the manual “SIPROTEC Communication module, PROFIBUS DP -
Communication profile”, chap. “Scaling of measured values”, for general information
about the conversion and scaling of measured values.
Table 1-2 Parameter DP_CountersWithStatus
The default value is 1.
Toggle bit timer
reload value GlobalSection.DP_Ttoggle
Reload value (in 100 ms) for the supervision timer of the Toggle bit mechanism (ref.
to chap. 1.4.1.4).
The value 0 disables the Toggle bit mechanism.
If the reload value for the Toggle bit timer is less than the reload value for the PROFI-
BUS DP responsemonitoring timer1thenthe reload value of the Toggle bit timer is set
equal to the reload value of the response monitoring timer in the module firmware.
The default value is 30 which corresponds to 3 seconds.
DP_Counters
WithStatus Status bit for counters Float to integer conversion after
multiplication with scaling factor
0 no without rounding of the measured value
1 yes without rounding of the measured value
16 no with rounding of the measured value
17 yes with rounding of the measured value
1. Response monitoring: PROFIBUS DP standard mechanism for communication supervi-
sion. The reload value for the response monitoring timer in the slave is calculated by the
PROFIBUS DP master with the network size, the baud rate etc. This reload value then
is sent as part of the Set_Prm telegram to the slave.

Maximum value of
Start-up time GlobalSection.DP_Red_TsprimMax
During the redundancy start-up until the initial PRIMARY/BACKUP decision by the
PROFIBUS DP master, both modules have alternating the state S_PRIMARY and
S_WAITING (ref. to chap. 1.6.1).
A state change between the modules is carried out after the time Tsprimary.
Tsprimary starts at 2 s and will be increased by 2 s after each state change until the
configured maximum value TsprimMax.
TsprimMax is entered in 100 ms steps.
If a value is entered which is not divisibleby 2 seconds then TsprimMax is rounded up
or down to the next 2second value by the module firmware. All values less than 2 sec-
onds (including 0) are treated as 2 seconds.
The default value is 20 which corresponds to 2 seconds.
Because this is equal to the Tsprimary start value, all 2 seconds a state change
between S_PRIMARY and S_BACKUP is executed with the TsprimMax default value.

1.3.2.1 Error system interface
IfPROFIBUS DP isselected as systeminterfacethenthe tagging “SysIntErr”(Error
System interface) is available in the device parameter set to signal a communication
error to the PROFIBUS DP master.
The reaction of the SIPROTEC device to a communication interruption using the tag-
ging “SysIntErr” is described in the manual “SIPROTEC Communication module,
PROFIBUS DP - Communication profile”, chap. “Communication interruption”.
A redundant PROFIBUS DP slave differs from this behavior by the fact that only a
communication error of both modules leads to set the tagging “SysIntErr”:
Table 1-3 Tagging “SysIntErr”
Module B
Communication OK Module B Communication error
Module D
Communication OK “SysIntErr” = OFF OK “SysIntErr” = OFF OK
Module D
Communication error “SysIntErr” = OFF OK “SysIntErr” = ON Error
Note:
If the Toggle bit mechanism is activated (Toggle bits, ref. to chap. 1.4.1.4) then a com-
municationerror alsowill besignaled (despitecorrect PROFIBUSDPdata exchange):
•as long as the Toggle bit mechanism was not started by the master device,
•when the Toggle bit timer expires.
