2.2.3 LED Indicators
The Saitel DP modules include some visible LEDs (light emitting diodes) on the front side. All
acquisition modules have common LEDs, and the rest are specific for each module, which are
detailed in the corresponding user manual.
The front panel of each acquisition module has a red indicator DIA and a green indicator RUN. The
module performs a self-check during the start-up process. When successful, the red indicator is
switched off and the green indicator displays the module’s configuration status.
If any problem is detected, the red indicator DIA is switched off. The meaning of these LEDs
depends on the module type and it is explained in the user manual for each module.
This information will only be valid if the module is completely configured and operational.

2.4.2 RTU Basic Functions
The control unit (CPU) performs the control functions for the complete system, centralizes the
information acquired by other modules, and executes the programmable logic control,
communication protocols and user-specific applications.
The communication with I/O modules is established by an internal high-speed bus that makes the
system highly reliable even in noisy environments. This bus is implemented in the backplane
Figure 11 – Communication between the CPU and I/O modules.
The CPU module controls and manages the following functions:
Bus Controller
The Baseline software installed in the CPU controls the operation of both, CPU and I/O modules
connected to the backplane.
This control includes:
• Operation mode monitoring. It performs functions as hardware and software Watchdog control,
• Interface with the operator through the console, webApp (for supervision and maintenance)
• Firmware upgrade by SFTP or webApp (using an Ethernet port) or USB 2.0 port.
RTU Configuration
The CPU maintains and manages the information that supports the real-time database, coreDb. In
this database, the I/O signals are related to the communication protocols signals. The configuration
is based on XML files that are generated with the Easergy Builder tool. These files are generated
on a PC and sent to the CPU via an SFTP connection through Ethernet ports.

source is used.
Pag 28
User Manual – Saitel DP Platform
30/06/2020
The available synchronization sources are:
• GPS: A GPS connected to a serial port. The time received from the GPS is used to set the
system’s clock and the RTC.
• SNTP: A SNTP source through Ethernet. CPU modules can operate as an SNTP client or as
an SNTP server.
• Protocol: Most control protocols allow synchronizing slave devices.
• Console: The user can set the system's time manually from the console terminal.
• IRIG-B: It’s possible to configure the CPU as a server and/or client. The communication always
will be made with IRIG-B compliant devices.
If the synchronization source is not configured, the console device will always be created by
default. The console operates as the lowest priority when another source is configured.
CPU Communications
Saitel DP supports the following communication protocols with field devices:
• IEC101 master and slave.
• IEC103 master.
• IEC104 master and slave.
• DNP 3.0 master and slave.
• Modbus master and slave.
• IEC61850 client, Edition 1 and 2.
• IEC61850 server, Edition 1 and 2.
I/O Acquisition
The CPU manages the information exchange with the I/O modules. This information is sent from
the acquisition module to the CPU through the bus.
The software in the CPU adds the following features:
• Processing I/O information, which offers an added value to the information from field.
• Accessing the internal bus to exchange information with the I/O modules.
Real-time Database (coreDb)
The core of the Baseline Software Platform is the real-time database or coreDb. It is a real-time
database which stores not only the information acquired from field devices, but also the information
about the status of the CPU modules and I/O modules included in the RTU.
coreDb also relates the acquisition signals to the communication protocol signals. This database is
generated in the CPU by using the configuration information.
The information which is received from field in real time is processed, stored in the coreDb and
then related to the communication protocols signals of the RTU, which function is to transfer that
information to the master device.

coreDb can also have as a source of information the result of a logic, which can be implemented by
a third-party software such as ISaGRAF® or within the database itself witch an internal device of
the type “Formula”.

2.5 Redundant Configurations in Saitel DP
Due to the wide range of redundant configurations supported by Baseline Software Platform and
Saitel DP, it is necessary to make a detailed analysis in order to determine the concepts applicable
to functionalities and to set a common terminology.
It should be highlighted that redundancy always intends to increase the level of reliability and
availability of the critical elements within a control system.
Redundant configurations are defined to strengthen the following parts of the control system:
• Power supply: This is the first doubled element in the system, since a power supply fails
would mean a total power-off of the system. Power supply units are also devices which transfer
powers, sometimes extremely high and could cause a significant wear of the components. All
Saitel P modules and most auxiliary elements support a redundant power supply.
• CPU: The SM_CPU866 and SM_CPU866e modules allow defining configurations with CPU
redundancy with a high level of flexibility meeting the specific requirements of any system.
• Acquisition bus: The acquisition bus allows the CPU to acquire data from acquisition
modules. Saitel DP backplanes include a double acquisition bus. The CPU module together
with the acquisition modules implement the functions to make an efficient use of these
redundant communications.
• Communication channels: Several master and slave communication protocols support a
double communication channel, which are switched with certain rules according to the protocol.
• System’s duality: All the system’s components are doubled under this configuration. This is
the typical configuration of data hubs and communication front-ends.
Different types of redundancy can be combined in order to make the system as much robust as
possible with doubled elements..
2.5.1 Power Supply Redundancy
Power supply redundancy consist of the use of multiple power supply units for the same backplane.
Thus, the power supply reliability is much improved.
The SM_BPX and SM_CHX backplane have two different power supply options available:
• Power supply using SM_PS40 units
• Power supply using external power supply units.
In both cases, it is possible to have a simple or redundant configuration.

components may be damaged.
Each power supply must be available to provide the 100% of the required power, regardless if
SM_PS40, an external power supply or a combination of the two options is used. Therefore, there
are four possible redundant configurations

adequate wiring.
Power Supply Redundancy in SM_CHX
The SM_CHX backplane has the same power supply options as the SM_BPX backplane, so the
redundancy configuration is similar.
The difference is that the connectors for external power sources are located at the back of the
circuit board rather than on the side (see connector 3 in Figure 49). The pinout of this connector is
detailed in section 0 of this manual.

2.5.2 CPU Redundancy
The SM_CPU866e module, together with the backplanes (SM_BPX and SM_CHX), supports the
definition of different redundancy configurations of the CPU.
The redundancy types are defined by:
• Physical site: The two CPU are installed consecutively in the same backplane or in different
backplanes.
• Switching mechanism: The switching can be arbitrated by the MSAC module or managed by
the CPU modules themselves.
• Switching type: Both "cold" and "hot" switching are possible. In the first case, the database of
the STANDBY device is not updated with the ONLINE device’s database, but it only updates
when switching is triggered. In the second case, the STANDBY device is constantly updating
the database with the ONLINE device.
• IP address allocation: Baseline Software Platform allows configuring a number of IP
addresses associated to the ONLINE CPU. These addresses are assigned dynamically to
allow CPU modules in redundant systems to inter-communicate and use the same IP address
after switching.
2.5.2.1 CPU Physical Site
Two CPU Modules in the Same Backplane
This is the simplest redundant configuration as it makes the best use as possible of the features of
the backplanes (SM_BPX and SM_CHX). It is the only configuration which allows the two CPU
modules to share the SM_SER communication modules. It also allows (alike in other
configurations) acquisition modules to be shared.
If there are two CPU modules in the same backplane, the switching mechanism can be controlled
by the MSAC module or be managed by the two CPU. In this case, Both CPU can
intercommunicate through a dedicated high-speed channel included in the backplanes or through a
serial or Ethernet link.
Its main disadvantage is that a malfunction in the CPUs’ backplane, caused by any of the modules,
affects the two CPU similarly. Therefore, there are simple faults which might make the two CPU
fail.

This configuration requires an additional backplane; moreover, the number of SM_SER
communication modules, which are doubled, cannot communicate with the CPU if they are nor in
the same backplane.

modules. In this case, both CPU can intercommunicate through a serial or Ethernet link.
This configuration prevents a simple failure in the backplane from affecting the system completely.
located, since the CPU will not be able to access the acquisition data of the modules located in
the backplane of the other CPU.
Figure 22 – Two CPUs in different backplanes.
2.5.2.2 Switching Mechanisms
MSAC Module
MSAC (Signaling, Arbitration and Switching Module) can, in redundant CPU configurations,
perform the following functions:
• Using a powerful "hardware" protocol, it detects if a CPU is operational or not. It arbitrates
which of the two CPU is ONLINE or STANDBY.
• If a GPS is used for synchronization, the synchronization signal is broadcasted to the two CPU.
• It links each CPU to a relay output, which is activated if the device is operational (ONLINE or
STANDBY) and deactivated if a FAIL status is detected. This relay output can interrupt the
output polarization, signaling, etc.
The MSAC module includes a set of LEDs to indicate the state of each CPU.
Pag 35
30/06/2020
User Manual – Saitel DP Platform
Figure 23 – Switching using the MSAC module.
The CPU (A or B) reports its status to the MSAC. If it is ONLINE, it generates a pulse train, which is
not generated if it is FAIL. The MSAC reports the other CPU whether it should switch to ONLINE or
not, and if the other CPU is in a FAIL status.
RCAP Protocol
If there is no MSAC module installed, the switching van be performed through the RCAP
(Redundancy Control Asymmetric Protocol) protocol.
In this case, there is a communication channel, which can also be redundant, between the CPU
modules. Using this channel, the CPU modules manage the switching through a Schneider Electric
proprietary protocol (RCAP). The communication channels include:
• Ethernet. Communications are established using an IP address through an Ethernet port.
• Serial. The CPU modules communicate using a serial port in the SM_CPU866e module.
• Communication through the backplane (only available when the two CPU are installed in the
same backplane). The backplane incorporates a dedicated serial channel so that the CPU
modules can communicate.
This switching mechanism is specially recommended when the two control modules are installed in
the same backplane or when they are installed at a short distance.
2.5.2.3 Switching Mode
There are two types of switching: “Cold Data” and “Hot Data”.
Cold Data
Under this mode, there is no communication between the two CPU, and when the switching is
performed, the new ONLINE CPU initializes with a database with default values.
Pag 36
User Manual – Saitel DP Platform
30/06/2020
Figure 24 – Switching status under Cold Data mode.
Hot Data
There are three status defined for each CPU:
• STANDBY: Under this status, the CPU is operational, the defined software modules (coreDb,
synchronization, web server,...) in AutoLoad.cfg, the supervision module and ISaGRAF are
loaded. The other BinControllers are not executed. The CPU does not access to the acquisition
bus, the SM_SER communication bus or generate the PPS. The database is not updated.
• ONLINE: Under this mode, the CPU is operational and all applications are executing. The
protocol BinControllers are executed. The communication is activated through the acquisition
bus and SM_SER communication bus; the PPS is generated.
After the switching, communications and acquisition are resumed, and all parameters use
default values.
• FAIL: Under this status, the CPU is not operational.
By adding a second CPU to a control system, this configuration has the advantage of improving
availability considerably so that maintenance, database modifications and testing tasks can be
carried out over the STANDBY CPU, not comprising the system’s performance.
Under Hot Data mode, there is a high-speed communication channel (Ethernet or backplane)
between the two CPU, which is used to update the STANDBY CPU’s database with the ONLINE
CPU’s database. When a switching is performed, the new ONLINE CPU starts with updated
values. In this operation mode, database IDs must be the identical.
The update is performed by exception; it only sends the values of the points which have changed,
except for the first time when the entire database is updated.
The information which is shared by the two CPU is exclusively related to coreDb points; internal
information about the BinControllers is not shared. This is the reason why, some information may
be lost after a switching. Examples of this type of information are events and commands.
The use of a BinController of the laq type which uses a Profibus protocol sending the status of the
outputs constantly achieves that the values sent as outputs will match the values corresponding to
the actuations performed on the points associated in coreDb.

Hot Data switching has several peculiarities. We recommend you to contact Saitel Support
For BinControllers using other protocols (101,104, DNP) which send commands by exception, no
command is sent after a switching.
ISaGRAF and supervision BinControllers are executed in the STANDBY CPU. The points with
sources in the supervision BinController are not shared by the two CPU.
Both CPU can initialize in different moments, so there is no guarantee that ISaGRAF sequential
program is under the same status in both CPU. If status synchronization between both programs is
required, it must be implemented in the program itself using ISaGRAF variables mapped to coreDb
signals.

There are three status defined for each CPU:
• STANDBY: Under this status, the CPU is operational, the defined software modules in
AutoLoad.cfg (coreDb, synchronization, web server,...), the supervision module and ISaGRAF
are executed. The other BinControllers are not executed. The CPU does not access to the
acquisition bus, the SM_SER communication bus; the PPS is not generated and dbNET is
disabled. Data related to the point status are received from the other CPU and updated in
coreDb.
• ONLINE: Under this mode, the CPU is operational and all applications and protocol
BinControllers are executing. The communication is activated through the acquisition bus and

2.5.3 Acquisition Bus Redundancy
The backplanes in Saitel DP include four communication buses for module interconnection.
Figure 26 – Communication buses in the backplane
These four buses are:
• Double Profibus-DP communication bus for the communication between I/O modules and
control module (PF1 and PF2).
• Communication bus for synchronizing acquisition modules (SYN).
• High-speed communication bus for the communication between the control module and
communication modules, SM_SER.
• High-speed communication bus for the communication between the two control modules
installed at the same backplane (CPU).
The acquisition bus redundancy in Saitel DP is achieved by the Profibus DP (RS-485) double bus.
This bus enable distributed acquisition architectures to be defined; it is highly flexible and robust
and can cover distances of up to 1500 meters. The communication rate for these channels is
selectable from 9.6 kbps and 1.5 Mbps.
Profibus redundancy is expandable to other backplanes since the channels: PF1, PF2 and SYN
are outputs in the backplane through the expansion connectors.

Profibus implementation for Saitel DP has the following features:
• There is only one serial controller for the two Profibus buses.
• Messages both from the master and the slaves are broadcasted through the two buses.
• Both the master and the slaves select the reception bus.
• The redundant bridge must be installed in the backplane in order to be able to select the
listening bus. If uninstalled, the listening bus will always be the bus 1.
• When there is no response in the master (including the attempts), the system switches to the
active listening bus.
• If communication is lost between a slave and the master through the two channels during more
than 8 seconds, this event is detected and the adequate diagnostic led is lit.
• The buses are alternatively monitored every minute. Therefore, both fault detection and
recovery may be delayed one minute.
2.5.4 System’s Duality
The system’s duality is the last option in order to maximize the system’s availability. Duplicity
means that all system's elements are doubled. This is the typical configuration of data hubs and
communication front-ends.
In terms of redundancy, there are two CPU in different backplanes with a specific number of
communication modules associated. Both hot and cold switching, which is arbitrated by the MSAC
module, are possible. Even though generally there is no acquisition, it is possible to have
acquisition modules installed in the CPU's backplanes in this case.
Communication channels are multiplexed by using a logic device.

2.5.5 Recommendations
Following paragraphs provide information about the different types of existing redundancies and
which is the most adequate redundancy for each case. Due to the wide range of redundancy
possibilities available for Saitel 2000DP, these proposals are general and open, so it is possible
that the least recommended options here are the most appropriate for a specific project
2.5.5.1 Power Supply
In non-redundant configurations, the use of an external power supply module is recommended as
the most appropriate option for the backplanes. For the same reasons, it is the recommended
option here.
In this case, two slots are not occupied; they can be used for communication or acquisition
modules. Moreover, since the power supply source is different to the polarization source (if
acquisition is available), one can be down without affecting the other.
The table below summarizes the options in order of preference:

It is less robust than the existing channel in the backplane, but it is
the only method available to update the database of the stand-by
CPU if it is installed in a different backplane. Whenever possible, it
is recommended to have this channel in a dedicated network.
2.5.5.3 Acquisition Bus (Profibus)
If the specific subsystem consists only on a backplane, a Profibus redundancy (that is, setting the
enabling jumper or not) has no effect. Nevertheless, when communications with the acquisition
must be established outside the backplane, then they must be more secured.
To do so, it is possible to take two channels from the same expansion connector or obtain each
channel for a connector.
When distances are relatively long, copper wires should not be used, but optic fiber instead. In this
case, the recommended converter is BP2F.
wires between different cabinets.
For the particular case of a system with redundant CPU modules in different backplanes, the status
of Profibus communications in the STANDBY (inoperational) CPU can be monitored by the
ONLINE CPU.
To do so, at least one acquisition module is required in the CPU backplanes. The ONLINE CPU will
be able to access to those modules, and the status of the module’s diagnostic signals of the
STANDBY CPU will be the status of the Profibus channel (or channels) of the STANDBY CPU.
Therefore, the status of the Profibus channel in the backplane of the STANDBY CPU will be
provided by the acquisition module.
Following paragraph includes some example of Probifus expansion.
If the bottom CPU is the ONLINE CPU will be able to know that the upper CPU in STANDBY status
has lost the Profibus channel when the I/O module does not respond.
2.6 RTU Expansion
The RTU can be expanded to other backplanes (including only I/O modules) according to the
system requirements. All technical information about RTU expansion is included in chapter

3.1 General Description
The Baseline Software Platform is used with Saitel products and other Schneider Electric products.
It consists of:
• Real-time operating system (RTOS): Linux.
• Real-time applications and configuration files (XML format).
• Software tools: Configuration, local and remote maintenance, supervision and monitorization.
The following figure shows the different applications included in the software platform, as well as
additional applications (Devices) implementing new Devices or protocols to upgrade Easergy
Builder.
Figure 33 – Baseline Software Platform.
The operating system abstracts the hardware from the software applications and manages the
applications in real time. It integrates the basic protocols to access the remote unit (SFTP, SSH,
etc.) and manage multiple users.
The real-time database, named coreDb, is probably the most important element. All the other
elements are developed around coreDb.

User Manual – Saitel DP Platform
NOTICE
It should be noted that any coreDb signal can be associated to more than one source; this is
Figure 34 – Relation between coreDb and other applications.
The following concepts are related to coreDb:
• Device Controller (also referred to as Controller): Real-time application that accesses coreDb.
Each Controller acts as a producer and/or consumer of information managed by coreDb.
• Point: Each register of coreDb is a point. A point can be included in the table Status, Analog,
Command or Setpoint.
• Device: A set of I/O points that share a common source/destination. A typical example of a
Device is an IED that communicates with the RTU, or the representation of a SCADA
exchanging information acquired or generated by the RTU. A Device is always associated to a
type of Controller.
• Source: Origin of the value of a coreDb data point. Any coreDb data point can have several
different sources (in one or several Devices). This means that a value of a database point can
be configured to be updated by several different entities.
• Destination: Target of the value of a coreDb data point. coreDb data points can be configured
to have several different destinations (in one or several Devices).
only applicable to Command and SetPoint tables. Allocating more than source to one point is
not recommended in Status and Analog tables.
• Coordinate: Point identification within a Device. It is unique for each point and has a different
structure for each Controller.
• Configuration Plugin: Specific Configuration plugins extend the Easergy Builder application to
configure Device Controllers.
The user can modify the configuration of each Controller and Device using the appropriate Plugin.
Once the database is completely configured, the files with the new information can be generated
and transferred to the RTU, where they will be processed by the software on startup.
Pag 48
User Manual – Saitel DP Platform
30/06/2020
NOTICE
The information exchange, that is, the exchange of configuration data between the RTU and
Easergy Builder is not continuous, but performed through XML files under user’s request. When
the configuration is modified in Easergy Builder and the XML files are sent to the RTU, it
is necessary to reboot the RTU.
3.2 Main Elements
For the user, the Baseline Software Platform has the following main elements:
3.2.1 coreDb – Real Time DataBase (RTDB)
coreDb is the real-time database which stores not only the information acquired from field devices,
but also the information about the CPU and I/O modules status that are part of the RTU. coreDb
also relates the acquisition signals to the communication protocol signals. This database is
generated in the CPU by using the configuration information.
The information which is received from field in real time is processed, stored in the RTDB and then
related to the communication protocols signals of the RTU, which function is to transfer that
information to the master device.
Figure 35 – Interfaces with coreDb.
CoreDb points are organized in four tables: Status, Analog, SetPoint and Command to group the
different types of points. These internal tables present the following differences:
• Depending on the point type: status, and command tables support integer values, whereas
setpoint and analog tables manage floating values.
• Depending on the treatment of the point: Status and Analog points can be locked or reset to
initial values, whereas the other two signal types cannot. All types can retain the value in a
non-volatile memory.
Pag 49
30/06/2020
User Manual – Saitel DP Platform
3.2.2 Devices
Each type of device keeps a list of its associated points, identified by unique labels. These labels
allow the identification of each device point unequivocally as source or destination of a coreDb data
point.
Each point is a piece of information produced (or consumed) by a Device. Within a single Device,
point identifiers (coordinates) are unique and cannot be used by two different points.
3.2.3 User Interfaces
The user can use the following tools in order to access to the RTU information:
• Easergy Builder: configuration tool for Schneider Electric RTUs that uses the Baseline
Software Platform. It has to be installed in a PC, and among other features, it can be used to
perform: offline configuration of the general settings of an RTU (IP address, user
administration, communication channels and so on), design and maintenance of coreDb,
administration of the synchronization mechanisms, configuration of the supervision and
monitoring features.
• Console: advanced diagnostic (for expert users only, local or remote connection). It is possible
to connect the PC through the serial cable to the CON port or using an Ethernet cable to an
ETH port and SSH.
• webApp: is the local and remote user interface for online monitoring, operating and
maintaining the CPU.
3.2.4 Cybersecurity
The module SM_CPU866e is provided with a standard security policy and a default RBAC (RoleBased Access Control) model), allowing different levels of user access adapted to this CPU usage
compliant with standard IEC 62351-8. This model is defined and managed by a special tool - CAE.
Based in this model, authorized users can create and manage other users in the system. Also, the
CPU includes a firewall.
3.3 Software Tools
A basic configuration is included with CPU, which should be adapted to the requirement of the
system. Depending on the CPU and the baseline installed on it, following software tools will be
available for configuration or maintenance:
• Easergy Builder: Engineering tool for the RTU OFFLINE configuration. It allows to include and
adapt the different functions of the RTU to the system where it is being integrated. It is a
software tool that needs to be installed on a PC.
• CAE: Only available for SM_CPU866e with baseline 11.06.00 and later. Engineering tool for
defining the security policy and assigning roles to users. It allows defining a series of rights and
responsibilities in the system for authorized users. It defines WHO, WHAT, WHEN and HOW
can the user do it, according to the RBAC model. It is a software tool that needs to be installed
on a PC.
• webApp: Web tool for online maintenance and monitoring of the RTU with SM_CPU866e as
CPU. Using the configuration defined in Easergy Builder and loaded in the CPU, the user can
consult and/or change some parameters through the WEB server. Unlike Easergy Builder,
webApp does NOT allow adding new features. Only the parameters included in the
configuration can be changed.
• SFTP: Manual exchange of configuration files (for expert users only).

3.5 Local Acquisition
Local acquisition is understood as the handling carried out by the system of the information arriving
to the CPU from field devices either through available integrated local acquisition in the CPU itself
or through external I/O modules.
This manual describes the configuration of the local acquisition signals in general terms, with no
comprehensive information about the configuration of each I/ module. This chapter explains how
information is processed by the CPU once it is received from each module.
For more detailed information about each I/O module, please refer section 5.6 and the
corresponding user manual.
3.6 Treatment of Local Acquisition Signals
3.6.1 Introduction
The input/output information processing is performed between the I/O modules and the CPU, which
will be in charge of the data exchange with the real-time data base by means of the internal data
bus. The information processing consists of treating and adapting the inputs and a conditioning of
the field outputs.
Figure 36 – Data processing in the CPU
All the signals stored in the real-time database are associated to quality information. This
information is generated by the status controller block, which uses the following information to
generate the quality flag:
• Diagnostic information, which is transmitted to the head unit by the I/O module.
• Diagnostic information and internal bus status.
• Information generated by other processing blocks in the same CPU.
The status of each signal and its associated quality bits can be viewed from Saitel Webtool, as
described in the user manual of this tool.
The following sections explain the types of data that Saitel DP can manage through the acquisition
block. These sections also describe the information processing procedure and the quality
associated to the stored data.
Pag 52
User Manual – Saitel DP Platform
30/06/2020
3.6.2 Digital Inputs
Saitel DP manages digital inputs with or without timestamp. In both cases, the values are 0 and 1.
The I/O module transmits the signal’s value to the CPU whenever it changes; it also attaches a
timestamp if using this type of signals.
The quality values associated to the signal’s values are:
• Invalid value due to a polarization failure.
• Locked signal.
• Invalid time; the module is not synchronized (only for signals with timestamp).
The types of points managed by RTDB and that are defined in function of these digital inputs are:
• Single digital.
• Double digital.
• Slow counter.
The digital inputs processing received from the field devices includes the functions explained
below. Each processing will be applied or not depending on the type of point generated.
Digital Filtering
Digital filtering allows eliminating the changes made to the inputs if these changes are not retained
for a minimum amount of time “Filtering Time” or TF.
The filtering response from a digital input is shown in the following figures.
Figure 37 – Digital filtering
Pag 53

User Manual – Saitel DP Platform
NOTICE
Change Memory
This functionality is applicable to all the points generated from digital signals, being single, double
or slow counters.
The memory time can range between 0 and 255 ms.
The change memory can store the changes detected in the inputs for a specified period of time
“Memory Time” or TM. It only applies to single and double points. It doesn’t apply in counter
signals. If the TM parameter is set to 0, this function is disabled
The change memory response for a digital input is represented in the following figures.
Figure 38 – Change memory
The memory time can range between 0 and 2559 ms.
Inversion
It only applies to single and double points. It doesn’t apply in counter signals. By using this
mechanism, the input can be configured as enabled when the value is “1” or disabled when the
value is “0”.
Edge Configuration for Counters
It applies only for signals defined as slow counters (DI_CNT). It allows configuring each slow
counter as single (DblCnt = “N”) or double (DblCnt = “Y”) counter. In the first case the counter is
incremented when a rising edge is detected in the input. However, the double counters are
incremented when both rising and falling edges are detected.
3.6.3 Digital Outputs
All Saitel DP output signals are direct, that is, each output signal is triggered by a direct command.
Each signal can be single or double, and it can be configured as latched or with an associated
pulse time.
Please note that when a point is defined as double in the coreDb, the two field signals to be
wired must be contiguous and on the same acquisition block.
IMPORTANT: When the RTU is operating under “Local” mode, all commands received on the
digital outputs are rejected. This is not applicable for analog outputs.
Pag 54
User Manual – Saitel DP Platform
30/06/2020
A single command is used to run the command:
• Running command Activated output.
• Completed command Deactivated output.
For a double command, two outputs are used to run the command:
• Deactivation command Output 1 “ON”, Output 2 “OFF”.
• Activation command Output 1 “OFF”, Output 2 “ON”.
• Two outputs can never be activated simultaneously.
The digital outputs processing includes the following functions:
Pulse Time
The pulse time is only applicable when the point is defined as pulsing; it specifies the output
duration. It can be configured through the system’s parameter called Execution Time or ExeTime,
which indicates the time in millisecond units, although with an accuracy of 100 ms. Its value is
selectable from 0 to 65535, but it shoudn’t be configured below 10 ms.
3.6.4 Analog Inputs
Input Range
Saitel DP allows managing analog input signals related to voltage and current. These analog
inputs have a quality bit associated which indicates whether the value is invalid due to a power
supply failure.
Previously to store the information into the corresponding point in the coreDb, the system performs
the following processing only for the first two types of signals:
It is possible to define in coreDb the input range for each analog signal received from an I/O
module. It even allows defining a different range for each signal.
The processing of the received analog measurement includes the value conversion to the range
defined in the coreDb.
The figure below shows the range conversion:
Figure 31 – Converting input range to engineering units.
Pag 55
30/06/2020
User Manual – Saitel DP Platform
NOTICE
The analog input processing distinguishes between unipolar and bipolar input ranges.
NOTICE
The RTU operation in “Local” mode does not affect the execution of analog outputs; only
Out-of-Range Detection
If the system detects that the value is higher or lower than the valid range, after the conversion to
engineering units (grayed area in previous figure), it will be indicated in the signal quality flag with
the corresponding bit activation,
Scaling to Engineering Units
This functional block can convert the analog measurement value expressed in field units to
engineering units (UI). The user defines the relation between two points within the field values
range and their corresponding values in the engineering units scale. Based on this relation, the
system defines the scaling formula which will be used to convert any field value within its valid
range to engineering units.
Range Checking
The user can define four alarm values associated to each signal: Very low, low, high, and very
high. Each value has an alarm flag associated which is transmitted as an input to the “status
controller” block.
3.6.5 Analog Outputs
Reset Value
Keep
commands (digital outputs) are discarded.
The processing of analog outputs consists of the following steps:
Figure 31 – Processing analog outputs.
The user must define the output reset value, that is, the output initial value after resetting the
acquisition block.
If the analog module is not in RUN status (LED Run is off) and maintenance is configured, the
analog output will retain the last value written to it, or the reset value otherwise.
Pag 56
User Manual – Saitel DP Platform
30/06/2020
Scaling to Field Values
This module performs the opposite process than the “Scaling to Engineering Units” in analog input
processing, that is, it converts the output value expressed in engineering units to its corresponding
field units.
Figure 31 – Scaling to field values.
The configuration of this scaling is the same as described for the processing of analog inputs in
paragraph “Scaling to Engineering Units”.
Output range configuration
The user can define the output range for each analog output using Easergy Builder. If the hardware
supports multirange, it should be configured with a range as close as possible to the user-defined
range. In any case, the user can define a value range different to the hardware range for each
analog signal.

• SM_CHX9 with 9 slots.
4.2.2.1 Mechanical Features
Both, SM_CHX9 and SM_CHX4 backplane modules are designed to be fixed on a metallic panel
19’’ wide, 6 U high and 180 mm deep. This chassis provides the mechanic support to fix all the
modules. The SM_CHX4 has a format that allows to mount two boards in the same chassis (one
next to the other). This option is the most suitable in solutions which give access to the rear part of
the electronic components.
For SM_CHX, the power connector, bus expansion connectors and configuration switches are
located on the back side of the card to be accessible from the back of the chassis.
The necessary space around the backplane must be respected in order to allow assembly and
disassembly of the modules.

• Use both connectors, which is the recommended option. In this case, it will be necessary to
wire only the pins 1 and 2 of each connector, with which we will have associated the external
source 1 to the first connector (J15) and the external source 2 to the second connector (J14).
For SM_CHX4, only connector J15 is available, so we have the two external power supplies

On a voltage drop, the backplane is shutdown when the voltage level falls to 5.0 VDC, and on a
power surge, the backplane is shutdown when the voltage level comes to 5.8 V
The best way to power the backplanes is depending on both the number of available power

4.4.2 BP2F Module (Expansion with Fiber Optic)
BP2F (Backplane to Fiber) is a RS-485 to fiber optics converter, specifically designed by Schneider
Electric for the communication between Saitel DP backplanes. This device allows the creation of a
fiber optics bus for communications between backplanes physically far away avoiding distance and
electromagnetic problems.
The BP2F device converts and regenerates the signal, allowing the connection of a large number
of nodes to the fiber optics buses.

Its main functional features are:
• RS-485 to fiber conversion. A RS-485 driver is used to communicate with Saitel DP’s
backplane; the fiber transceptors allow communicating with other buses.
• The consumption is minimal thanks to a low-consumption CPLD. The power is supplied
through the backplane.
• Signal regeneration between nodes.
• Transmission of pulse per second and Profibus communications.
• Conversion of Profibus-DP and synchronization buses.

4.4.2.2 Power Supply
The device’s main supply voltage is 5.4 V. There are two available options to achieve this:
• The expected voltage can be supplied to the device over the DB-9 port connected to the
backplane.
• Another options is to use a switched regulator to supply the required 5.4 V with an input range
of 4 ~ 6 V. This provides a stable supply voltage, better isolation and a wider operating range.

4.4.3 Using BP2F for Expansion
The device can establish Profibus and PPS communications. Depending on it, the RS-485
communications will have a behavior or another.
4.4.3.1 Profibus Communications
In Profibus RS-485 communications, the driver initializes in reception mode. If any communication
is received from RS-485 (start bit detection), it will be transferred to the fiber ports. When detecting
the first bit, the regeneration sequence starts, sending the byte with a half-bit delay. The stop byte
will be monitored. If there is an error, its LED will be switched on indicating the communication
error, so the rate settings must be revised.
In case of fiber optic Profibus communications, the fiber port will be polled. If any communication is
received, it will be sent to another fiber transmitter and to the RS-485 Profibus driver (activating the
driver previously)
Profibus conflicts are solved as follows:
• In order to prevent errors in two simultaneous receptions, when detecting a start bit in the
reception of any port, the reception through other ports will be cancelled until the message is
completely forwarded.
• Anti-streaming, in order to prevent a bus from cancelling all the communications, a system to
detect this anomaly is integrated (set to '0' for 1 ms). When a new transition to standby status is
received, this system will allow the bus to retransmit (RS-485 communications are interrupted)
Pag 89
30/06/2020
User Manual – Saitel DP Platform
• A relay contact closure on (terminal B1) is included to indicate bus anomalies. This signal is
used to report remote faults.
4.4.3.2 Detection of FO1 activity.
The BP2F can be configured to monitor the activity of the reception line in the FO1 port.
If the device doesn’t detect activity on the FO1 reception line, it will disable outgoing transmissions
through the FO1 transmission line. The relay output (B1) will open and the LED AUX will switch on
to indicate the anomaly.
When the BP2F detects activity in the FO1 reception line, transmissions through this port will be reenabled, the LED AUX will switch off and the B1 relay contact will close.
To enable this feature, set the configuration switch 6 to on (see paragraph 4.4.2.3). Otherwise, the
device will operate in standard mode.
4.4.3.3 Pulse per Second Communications
Based on a master or slave BP2F, you have the following issues:
• PPS signal in the master BP2F. The RS-485 port is always in reception mode and its signal is
transmitted through the fiber optic port with no delay. A pulse treatment is included in the
master BP2F which adds a minimal delay of 1 / 24 MHz to the master plus the propagation
time. The signal is repeated in the rest of devices, which only has a propagation delay through
logic ports.
• PPS signal in the slave BP2F. The RS-485 port is always in transmission mode. This port is
used to transmit the signal received from the PPS reception line. The signals received from the
reception port is transmitted through the transmission fiber port.
The number of supported nodes is limited by the maximum delay allowed in the network (<10 µs).

4.5 Field Connection
Acquisition modules can be connected to the field using two different procedures:
• A1: Terminal connection or direct connection. It is used when the length of the field cabling is
short, for example, when interconnections and assemblies are done within the cabinet, signals
are generated in a close site or proceed from an interface cabinet located at the same site, etc.
• A2: Flat-ribbon connection through terminal blocks. It is used when the distance between the
module and the signal source is long or when the cable gauge needs to be bigger than 0.5

due to the cabling layout.
mm
The following figures show the available connection options A1 and A2:
Figure 70 – Terminal connection (A1)
A module can be easily replaced by disconnecting the two field-connectors and removing the
module from its slot, in both direct and terminal-block connections.
In some modules, input circuits need to be polarized in order to perform signaling and command
functions.

4.5.1 A1 – Terminal Connection
The acquisition modules have Eurostyle ™ 20-way and 3.81 mm connectors, allowing the user to
use multiple solutions to your needs header connector (terminal screw, spring, small screw ... ). An
example is shown in the following figure:

4.5.2 A2 – Flat Ribbon Connection (Terminal Blocks)
When the connection is established through terminal blocks, they can be simple connecting
interfaces made up by a flat ribbon and terminals. These spring-type terminals with capacity for 2.5
2
gauge cables have a DIN 35 rail mounting base. The flat ribbon cable has 20 ways, so two
mm
terminal blocks for each module are required.
4.5.3 Wiring Recommendations for I/O Modules
It is necessary to take into account the following considerations regarding the wiring of the
modules:
• Recommended cable type: Low voltage computer with 20 x 0.14 by EMELEC.
Figure 73 - Cable for field connection
For connection, you should remove the shield of the cable between 8 and 10 cm and protect the
cut with an insulating material, as shown in the figure:
Figure 74 - Prepared cable for field connection
The shield at the end of each individual cable should be removed for a distance of 0.5 cm, which
will be the part of copper to introduce in the terminal:

You can see that the space is enough to the door to be closed:
Figure 76 - Position of the cables when they are installed
To avoid jerking and the weight of the cable doesn't fall on the terminal, when the module is
installed in the cabinet, both wires will be joined with a plastic bracket, and they should be fixed to
the cabinet or chassis too.
The following image shows an example:
Figure 77 - Mounting cables to the cabinet or chassis
4.6 Wiring recommendations for EMC
To improve the EMC behavior of the equipment, it is recommended to follow the following
indications in the wiring of the cabinet.
Considering the wiring types which could be used, there are several groups:
Table 14 – Wiring groups

1 Analog inputs and outputs.
2 Digital inputs and outputs.
3 Communications.
4 Main and auxiliary power supply and polarization of the field signals.
5 Ground protection for safety and EMC.

NOTICE
Analog, digital and communication cables should never share the gutter with power supply or
WARNING
Particular care must be taken when connecting the shielding to make sure it is effective.
4.6.1 Common Recommendations
• Whenever possible, cables of groups 1, 2 and 3 must be wired separately. That is, the analog,
digital, and communication signals should have separate gutters.
• If separate wiring is not possible and the number of signals is low, exceptionally this gutter may
be shared. In this case, as analog and communication signals are the most sensitive, these two
types of signals should be wired through the same gutter, whereas digital signals should be
wired separately.
• When none of the above is possible, it is extremely important to avoid analog, digital and
communication signals to be wired in parallel. If there are some sections in which parallel
wiring cannot be avoided, these should be as short as possible.
• If the cables need to be crossed, theses crossings will be perpendicular to each other.
• In order to increase protection in the field inputs and outputs, terminal blocks are normally used
to reinforce the protection barrier. The power supply and protection terminal blocks of DI, DO,
AI and AO are protection barriers. The input wiring to these elements must always be
independent from the output wiring of these barriers. They should never share the gutter.
polarization cables.
Field input signal cables must never be laid using cables with filtered signals.
4.6.2 Analog Inputs and Outputs Signals
In the case of analog signals, always shielded cables should be used for the connection of the
analog module to the resistor and protection terminal block. The cable shield corresponding to the
terminal block connection must be grounded using a DIN-rail terminal.
Figure 78 – Analog signals wiring.
4.6.3 Communications
The communication bus can be installed using 2-wire communication or 4-wire communication. In
order to increase the immunity to electromagnetic interference (EMC), the use of a shielded twisted
pair is recommended.
The shield connection depends on the equipotentiality between the connected devices:
Pag 94
User Manual – Saitel DP Platform
30/06/2020
Connecting NOT equipotential devices could be hazardous for persons and equipment.
• Guaranteed equipotentiality: Both devices are connected to an ground system, so that the
same potential level is guaranteed The shield must be connected at both ends.
• Limited equipotentiality: Both devices are connected to ground but not to the same ground
system. To limit the difference of potential that can be produced among them a cable with the
appropriate cross-section will be installed between the grounding of both. The shield must be
connected at one end.
• No guaranteed equipotentiality: Ground connection of both devices can’t be guaranteed
(both devices must be connected to a ground system). Copper mustn’t be used in this case.
RS-485 Communications
For RS-485 the pairs are shielded individually or all together by a copper braid. The
recommendations for the cable are:
• Resistance: < 100 Ω/km.
• Section: 0.22 mm
• Characteristic impedance: 120 Ω.

(24 AWG)
DANGER
• Maximum length: 1200 m.

For RS-422 the pairs must be shielded individually. The recommendations for the cable are:
• Resistance: < 100 Ω/km.
• Section: 0.22 mm
2
(24 AWG)
• Characteristic impedance: 100 Ω.
• Maximum length: 1200 m.
4.6.4 Group 4 (Power Supply)
The power supply for the electronic elements is the main barrier between the existing disturbances
in the power supply line and the system. That is the reason why, this power supply is equipped with
some additional filters to achieve a good EMC behaviour of the system. It is extremely important to
keep the filter’s input wiring independent from the output wiring.
Polarization
The output of the polarizing power supplies follows the same route in the field as the digital signals
in which they are used, so the treatment is the same as for a field input/output signal. In some
projects, supplementary filters are installed. In these cases, the wiring should be independent for
the filter’s input and output.

User Manual – Saitel DP Platform
Auxiliary
Filtering
Figure 79 – Polarizing power supply output.
The auxiliary power supply and its wirings do not have any galvanic connection to Saitel DP, so
they should be sufficiently separated from each other (independent gutters and layout) in order to
avoid possible disturbances to reach the Saitel DP wiring itself. In some projects, supplementary
filters are installed. In these cases, the wiring should be independent for the filter’s input and
output.
Generally, a filter will be included as a means to reinforce the protection of the power supply of the
electronic elements. The use of filters for the polarizing power supply is optional.
The polarizing power supply should never be combined with the power supply for electric elements.
The filter cannot be shared in any case, as the polarizing power supply goes to field with the rest of
inputs/outputs. As shown in the figures, an incorrect connection of the polarization power supply
reduces the effect of the protection barriers.

4.6.4.1 Group 5 (Ground Connection)
General Recommendations
The cable section used should be have the appropriate size for each installation, and grounding
braid should be used whenever possible.
The equipment or cabinet need to have a ground wire in a given point in order to achieve a low
impedance for the rest of the elements. Horizontal copper bars, as well as vertical cooper bars
(whenever possible) should be assembled. All metal pieces of the equipment shall be connected to
the ground protection. If metal cabinets are used, the cabinet's walls can also be used to distribute
the EMC ground.

one element would leave other elements within the cabinets without an ground connection.
Previous figure shows a correct connection, in which all metal elements are connected through a
dedicated cable to the ground-connection bar. In following figure, the two ground connection cables
are joined together to simplify the connections, resulting in an incorrect ground connection.
Figure 82 – General scheme of an INCORRECT ground connection.
Ground Connection to avoid Electromagnetic Disturbances (EMC)
The connections to metal parts (which are ground connected) must be rather short.
Ground distribution will be done using the shortest cable lengths as possible. It is very relevant that
EMC ground-connection cables are as short as possible, therefore the entire cabinet metal surface
will be used for the connection.
The electronic elements with metal coating, such as power supplies, must be ground connected in
two points. Firstly, they are connected to the ground protection using a cable with section enough,
linking the ground terminal and the ground-connection bar. Secondly, there is a second cable
linking the ground terminal to the closest metal surface (as shown in the previous figures through
the power supply elements).
It is recommended to use flexible grounding braid for mobile earth parts (such as the cabinet’s
doors). The grounding braid must be short but with a wide surface (the surface is an essential
value in order to reduce high-frequency disturbances).
