Redundancy via SCA-RS
14 Unrestricted SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
1.1 Overview
1.1.1 Redundancy
With redundancy one part of the system is used for the operation (active), while the other
system part is on standby.
For simple redundancy applications the processing elements are designed redundant,
whereby one is active and the other is passive (Standby). With a failure of the active
processing element a switchover to the standby can take place without any operational
interruption, refer also to section 1.1.2, Synchronization (this way redundant automation tasks
can be realized simply and inexpensively).
With redundant communication routes, both communication interfaces can be used at the
same time for the purpose of load sharing. If one communication link fails, all data are sent
over the communication link still available. In this case one speaks of functional redundancy.
Here, this concerns communication redundancy between two identical single point protocol
elements (PRE). These must sit on the same protocol module (in other words PRE0 with
PRE1 or PRE2 with PRE3). The data are sent and received over one or the other protocol
element. In the error free state the distribution can take place either fixed (data split mode) or
according to load (load share mode)
For redundant Front-Ends the switchover can take place separately for each communication
interface. This increases the availability, especially with redundant communication routes to
the RTU.
If automation units (AU) are designed redundant, a permanent comparison of the open/closed
loop user programs can also be carried out with the help of a vendor module in the CAEx plus
application (application-related redundancy)
Based on the system information received, a voter decides which system part is active, when
this is deactivated (switched passive) and when it activates the passive system part. The voter
therefore performs the switchover from one system part to the other, refer to section 1.1.3,
Voting.
For SICAM AK there are mainly two distinct types of redundancy:
•CPU Redundancy
Always means the presence of one or multiple CPU pairs (including SSE and PE) within
one AU
•AU Redundancy
Always means the presence of one AU pair with the same functionality.
This type of redundancy refers to two AUs.
In the case of CPU redundancy, up to 5 redundant processing elements can be configured in
one SICAM AK. Since the power supply can also be designed redundant, an availability is
achieved close to that with two separate automation units.

Redundancy via SCA-RS
SICAM RTUs, SICAM AK Redundancy Unrestricted 15
DC2-026-2.07, Edition 10.2016
In the case of AU redundancy one differentiates between two types of switchover:
•Global redundancy switchover
(automatic voting by SCA-RS or application-related voting)
The entire AU is either in the redundancy state active or passive.
•Line-by-line redundancy switchover
(automatic voting by SCA-RS or application-related voting)
Only certain elements of an AU are switched to the passive state. In an AU some
elements can be active, others passive.
Prerequisites of Redundancy
Each of the two elements of the redundancy pair is already configured separately.
All redundant elements must have the same HW-FW configuration and be loaded with the
same FW version and the same parameters (state).
In certain redundancy configurations after startup messages in control direction (commands,
setpoint values,…) will be transmitted only to the active component /CPU because only the
active component has replied to the general interrogation and thus, the distribution criteria
(CASDU) has been learned.
If you want to have a transmission also to the passive components/CPUs, the following
solutions are available:
•selective data flow
•data flow filter
in the topology just enter "both directions" as data flow direction for a communication
interface, then „activation“ will be also sent without learned CASDU.
1.1.2 Synchronization
For the synchronization one can distinguish between two cases:
•Synchronization via HSL
The High Speed Link (HSL) is used for the synchronization of the redundant elements for
both types of redundancy (CPU redundancy and AU redundancy).
The interface is monitored by means of periodical monitoring messages. These monitoring
messages are generated and monitored by the system elements or automation units at
both sides of the interface.
•Synchronization via external communication
Here the monitoring time is dependent on the protocol. The system-technical parameter
Redundancy | Synchronization parameters | Red_Sync monitoring timeout
is used for monitoring the redundancy-synchronization interface and defines a time period,
within which a corresponding monitoring message is generated in case an error has
occurred (monitoring timeout for the interface). This means, if no communication takes
place within this parameterized time, the failure is detected. The value is to be set
according to the protocol used.
The control of the passive C-CPU is always timed by the active one, so that the function
diagram (FUD) runs simultaneously. Consequently the passive CPU has the same data as
the active CPU: the input data in the FUD on the active and passive are identical,
consequently the output data also have the same values.
A comparison (or a synchronization or an update) takes place in 2 cases:

Redundancy via SCA-RS
16 Unrestricted SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
•An update is requested by the user via the FUD
•An update is carried out automatically for the following changes of state:
─Going inconsistency of the control parameter
─Going inconsistency of the Ax-PE parameter
─Going redundancy synchronizing link failure (if FUDs are consistent)

Redundancy via SCA-RS
SICAM RTUs, SICAM AK Redundancy Unrestricted 17
DC2-026-2.07, Edition 10.2016
During an update the following parts of the control are transmitted to the passive CPU:
•Instance data of all program instances
•Instance data of all global variable objects
•Signal process image (excl. system data points)
•Status process image of the signals
What is synchronized?
•CAEx plus program
•Singular Ax PE
1.1.2.1 CAEx plus Program
The start of every single task of the CAEx plus application, which runs on both CPUs, is
synchronized over the HSL.
The exchange of multiple data points between the two CPUs, on which the CAEx plus
application is running, is performed by means of CAEx plus modules, refer to section 1.6.3,
Redundancy Control with CAEx plus.
Another kind of synchronization takes place by copying the process image of the CAEx plus
application from the active CPU to the passive CPU. This synchronization is carried out after
the startup or by the user.
The tasks are stopped during this calibration.
Please note, that redundant CAEx plus applications require longer cycle times than one single
application.
1.1.2.2 Singular Ax PE
The connection of one PE to two redundant BSEs is called singular PEs.
The active BSE communicates with the PE. The passive BSE receives information via HSL.
Redundant BSEs are located either inside one AU (CPU-redundancy) or in separate AUs
(=AU-redundancy).

Redundancy via SCA-RS
18 Unrestricted SICAM RTUs, SICAM AK Redundancy
Edition 10.2016, DC2-026-2.07
Example for CPU-Redundancy:
FUD is running, for instance, on both C-CPUs of the AU. Synchronization mode is HSL with
singular Ax-PEs.
Example for AE-redundancy with singular AX-PE-Bus.
Periodical data points from the PEs are detected automatically over the HSL and used by the
passive CPU.
Spontaneous data points are copied from the active CPU to the passive CPU.
If the communication between the passive BSE and the PE is interrupted, no further periodical
data points are updated on this BSE.
Spontaneous data points are flagged as NT (not topical) and also not updated.
Following restoration of the communication the periodical data points are updated
immediately.
If the FUD has been changed during the communication failure between the passive BSE and
the PE, the status of the CAEx plus application is not identical on both BSEs.
The synchronization of the spontaneous data points must take place by copying the process
image, see parameter Red_Sync Org_Abb, in section 1.4, Parameter Setting of the CP-
2017/PCCX25.

DC2-026-2.07, Edition 10.2016
1.1.3 Voting
1.1.3.1 Automatic Voting
The voting process is based on the definition of priorities in the redundancy table (see also the
description of the priority levels in sections 1.2.3.2 ff.) and applies for
•CPU Redundancy
The voting between both BSEs is performed automatically by the M-CPU (automatic
voting with CPU redundancy).
•AU Redundancy
The voting between both AUs is performed automatically by the SCA-RS, regardless of
the type of switchover (global and line-by-line redundancy switchover)
1.1.3.2 Application-Related Voting
The voting process is usually performed by an external application based on user data
messages received (more precisely: redundancy status information control messages) (see
also section 1.6, Redundancy Messages). However, the voting is primarily application-related,
the voter thereby also makes use of the error messages of the sum and detail diagnostic, in
order to generate its own redundancy control messages for the switchover.
This way the behavior of the external application can be defined with any level of flexibility.
The voting process is therefore not based on the definition of priorities.
1.1.4 Redundancy Switchover
For AU redundancy there are 2 switchover possibilities:
•Global redundancy switchover
(automatic voting by SCA-RS; application-related voting)
The entire AU is either in the redundancy state active or passive.
•Line-by-line redundancy switchover
(automatic voting by SCA-RS; application-related voting)
Only defined elements of an AU are switched to the passive state. Within an AU, some
elements can be active, others passive.

1.1.5 Overview of Redundancy Modes
Below the various redundancy modes are explained with the help of rough schematic
representations. Please note, that the representations are merely examples.
Example for CPU redundancy:
CPU redundancy with the predefined redundancy pair C-CPU 4 and 5 with fixed installed
HSL, the FUD runs for instance on both C-CPUs. The voting between both BSEs is performed
automatically by the M-CPU. The overview of a total system realized with CPU redundancy
can be found in section 1.2.1.3, SICAM AK - SICAM TM PE, Electrically and Optically
Connected.
Example for AU redundancy with SCA-RS:
Global redundancy switchover: all SEs of an AU are switched active/passive.
Line-by-line redundancy switchover: the SEs of an AU are switched active/passive selectively.
Please note the distances between the AUs and SCA-RS, see detailed hardware
configurations in sections 1.3.1.1 ff.
