3 General description
Modern factory automation and process control has ever more complex and sophisticated requirements. Control
is no longer the sole focus, but monitoring of components and processes becomes more and more important. This
is exactly the target application area of the intelligent and bus-capable power distribution system ControlPlex®. It
serves for the protection of industrial applications as well for monitoring and control. The bus controller CPC10PB
is the core of the system and provides the data exchange between superordinate and subordinate components.
These are on the one hand programmable control units and on the other hand it is the power distribution system
SVS201-PWR-xx, fitted with the electronic circuit protectors ESX50D-S1-xx. The bus controller CPC10PB can be
connected with four independent power distribution systems SVS201-PWR-xx and offers the possibility of
communication with up to 96 electronic circuit protectors. Communication options comprise transmission of the
operating condition, of measuring values and device information regarding the connected components, but also
changes of the product-specific parameters such as current ratings and execution of actions, e.g. ON and OFF
operation.
Information can be transmitted in a cyclical or non-cyclical mode to the superordinate control system or via an
available service interface to the connected service computer. If no connection is available to a superordinate
control unit, this will have no effect on the behaviour of the connected circuit protectors. The bus controller is
able to ensure their functionality even without a connection to a superordinate control unit. The saved parameters
will be used for this purpose.
The bus-capable power distribution system ControlPlex®offers the well-known E-T-A quality and reliability
with regard to overcurrent protection in combination with the innovative functions on the score of automation
technology.

3.1 Design of the entire system
The bus controller CPC10PB-Tx is the centre of the ControlPlex®system. Thanks to its interfaces, it allows
a consistent communication between the power distribution systems SVS201-PWR-xx with the plugged-in
electronic circuit protectors ESX50D-S1xx and the superordinate control units as well as the service computer.
The PROFIBUS-DP interface to the superordinate control unit features a 9-pin SUB-D connector. It allows
connection of the required control unit with the ControlPlex®system, thus enabling display and analysis of
the individual measuring values as well as diagnosis and control of the individual electronic circuit protectors. The
same functions are also made available at the USB service interface. Should there be any changes in the
automation system, all required measuring values of the electronic circuit protectors can be observed by
means of the service interface and, if this functionality has been released by the superordinate control unit,
they can be adjusted to the device parameters. This enables the user to have unrestricted access to the
safety-relevant functions even in the event of an interruption. Any occurring failures will be detected quickly
and can be remedied without delay. The CP system effectively reduces system downtimes and significantly
increases productivity.
The interface to the up to four power distribution boards SVS201-PWR-xx is realised with local bus defined
specially in-house at E-T-A called ELBus® . It transmits all cyclical and non-cyclical data in a cycle time of
230 - 730 milliseconds (depending on the version of the up to four power distribution boards SVS201-PWR-xx).
The power boards are mutually independent and are addressed in parallel by the communication unit. Each
specific version of the power distribution board SVS201-PWR-xx can be selected by the customers in available slot
numbers of four, eight, twelve, sixteen and twenty-four electronic circuit protectors.

3.4.1 Terminals for voltage supply
The operating voltage of the device is 24 V DC. Faultless operation of the device is ensured in a voltage range
of 18 V to 32 V. Current consumption on duty is typically 60 mA.
Using a supply voltage outside the indicated operating range can cause malfunctions or destruction
of the device.
3.4.2 Connector socket for the ELBus®, connector sockets X51, X52, X53, X54
These connector sockets served for connecting the communication unit CPC10 with up to four power distribution
boards SVS201-PWR-xx. Connection of the devices is realised with a one-to-one wiring mode. Preferably it shall
be realised with a cable type H07V-K 1.5mm². The cable does not have to be shielded specially. The cable length
between the bus controller and the power distribution board SVS201-PWR-xx must not exceed 2 m.
Use of the terminals for applications not provided for in the operation manual or improper connection
can lead to malfunction or destruction of the device.

3.4.3 USB service interface, terminals X61
The USB interface serves for connection of the service computer. By means of the available user software
ControlPlex®Views it is possible to import the measuring values of the individual circuit protectors, to change
parameters and to switch the devices on or off. The connection is realised by means of USB-2.0 type B. The
length must be less than 3 m. In the event of a bus communication with the superordinate control unit, the
user software has only reader access. If a change of the device parameters should be made possible on behalf of
the user software, this has to be explicitly released by the superordinate control unit.
3.4.4 Bus interfaces to PROFIBUS-DP, connector socket X81
The PROFIBUS-DP connection is realised via a 9-pin SUB-D connector. It allows direct connection of the
device with other PROFIBUS-DP participants. For mounting and special selection of cables and connectors

5 Operating modes of the CPC10PB controller
5.1 Operating mode: Start-up mode
The bus controller is initialised by applying the supply voltage. The device will carry out implemented programme
memory tests and self test routines. During this time a communication via the interfaces is not possible.
5.2 Operating mode: System error mode
If a failure is detected during the self test routines, the bus controller will change into operating mode System
Error. This operating mode can only be discontinued by way of re-starting the device and it prevents the data
exchange via the interfaces. If the bus controller is in the aforementioned operating mode, it is unable to
control the electronic circuit protectors and these will stay in the stand-alone mode (overcurrent protection).
5.3 Operating mode: Configuration error mode
If there are no valid or invalid configuration data available in the bus controller, it will change into the Configuration
Error Mode. This operating mode only allows non-cyclical data exchange. Cyclical data exchange is prevented.
Leave this operating mode upon receipt of the correct slot parameters and configuration data.
5.4 Operating mode: Stand-alone mode
In normal duty there is a connection between the bus controller and the superordinate control unit. Thus the
electronic circuit protectors are controlled and their parameterss are changed by the superordinate control unit.
Should the communication between both participants fail, this has no influence on the protective function of the
circuit protectors. In this case the bus controller CPC10 will automatically adopt the control and parameterisation of
the electronic circuit protectors, because are required data sets are saved within the CPC10. By means of the user
software ControlPlex®Views the electronic circuit protectors, their status and parameters can be accessed via the
maintenance and service interface. It is thus possible to change e.g. parameter data of the various electronic circuit
protectors. If the failure on the communication level is remedied, this operating mode will be left and the superordinate
control unit will take over control again as master. If during this time a parameter was changed while there was no
communication, this will be signalled to the superordinate control unit. In this case the user can correspondingly
define the control behaviour and it can be programmed in the programmable control unit. This allows the user to
select a reaction meeting his requirements.

13
5.5 Operating mode: Slave mode
In this operating mode the bus controller CPC10 is involved in a PROFIBUS-DP system. Communication to the
bus controller CPC10 works faultlessly and the controller can be addressed and controlled by the superordinate
control unit.
The behaviour of the bus controller with simultaneous use of a field bus interface and the USB service and
maintenance interface can be determined by means of the configuration of the device in the superordinate
control unit. It can be pre-selected there that the USB service and maintenance interface is granted either
only reader access or reader and editor access. In the event of editor access, changes of the parameterisation
of the electronic circuit protectors can be carried out in parameter selection to the field bus system. These
parameter changes will then be advised to the superordinate control system and can be adopted by it or also
overwritten. The user can select the behaviour accordingly.
5.6 Operating mode: Firmware update mode
The devices are supplied with a software programmed according to their functionality. If the functions of the
devices are extended, this will be carried out in the firmware. It is therefore necessary to carry out a firmware
update if the new functionality shall be used. More detailed information regarding the firmware update are
made available in the user manual of the software ControlPlex®Views.
5.7 Signalling of the various operating modes
The different operating modes of the bus controller CPC10 are indicated as follows:
Operating mode Indication of operating mode

6 Basic functions of the entire system
6.1 Internal cycle times
The cycle time of the system depends on the number of data to be transmitted between the bus controller
CPC10 as well as the number of slots intended on the power distribution system for the electronic circuit
protectors ESX50D-S. The cycle time decreases when using a power distribution board with four slots as
opposed to the cycle time with a power distribution system with 24 slots from 730 ms to 230 ms. During the
aforementioned period the status, the output voltage and the load current of each circuit protector is cyclically
transmitted to the CPC10. This has to be seen independently of the number of connected power distribution
boards SVS201-PWR with which the CPC10 communicates in parallel. The cycle time of the entire system
goes by the longest cycle time of the designed power distribution board. If for instance a power distribution
board with 16 and three more with 8 slots are connected to a CPC10PB-T4, the cycle time will comply with
the 16-slot-board and will thus be 530 ms for all four connected power distribution systems.
It is possible to choose the data quantity for the communication to the superordinate control unit. This can
be achieved by using the different data models. It is therefore possible to transmit either the status, the measuring
values for the load current and the output voltage of the electronic circuit protector or to only send the circuit
protector status to the superordinate control unit. The choice between the various data models is made available to
the user in the GSD file of the control system. These are configuration data which are transmitted to the store
programme control by means of the hardware configuration of the CPC10.

6.2 Hot swap of circuit protectors
The electronic circuit protectors ESX50D-S can be plugged into the power distribution board SVS201-PWR-xx at
any time. The ON/OFF button of the electronic circuit protector has to be in the OFF position.
For safety reasons the electronic circuit protectors ESX50D-S must only be plugged in in the OFF
condition.

15
After plugging in a circuit protector, it will automatically be parameterised if parameters are available for the
slot in question. Transmission of the parameters will be without interruption of the cyclical data exchange between
the communication unit SVS200-COM and the electronic circuit protector ESX50D-Sxx. After switching the device
on with the ON/OFF button the electronic circuit protector is ready for use.
6.3 Communication via the USB service interface
In addition to the PROFIBUS-DP interface, a maintenance and service interface will also be made available
to the user. It enables direct access to the bus controller CPC10PB. This is also possible when there is no
communication via the field bus interface. If the device is in the stand-alone mode, the user can access the
bus controller and the connected electronic circuit protectors at any time (reading or editing) via this interface. The
access in the slave mode can be parameterised by the user via the field bus interface. The delivery conditon
allows only reading access. Editor access has to explicitly be released by the user in the superordinate control
unit.
If the slot parameters are changed, the change will be signalled to the superordinate control unit. The user will
thus be able to process these changes in his control accordingly.
For parameterisation of the individual electronic circuit protectors the corresponding user software
ControlPlex®Views is available for the USB service interface. This software is available for download from
the E-T-A website and can be installed on a Windows®computer. The user software is described separately
in another manual.
7 Communication via PROFIBUS-DP
Depending on the designed configuration a different quantity of data bytes will be exchanged in the cyclical
data traffic between master and slave.
The system allows determination which data volume can be exchanged. Two different modules are selectable
per PWR board with different configurations (4, 8, 12, 16, 20 or 24 slots for the circuit protectors).
The module Control-Measure exchanges I/O data (status/control) and measuring values of the individual circuit
protectors with the master. The module Control only exchanges I/O data (status/control) of the individual circuit
protectors with the master.
The GSD file made available for the projecting tool allows the related configuration, the system recognises all
permitted configurations and processes the cyclical data defined in the projection.
Only the module I/O data CPC10PB-Device is firmly pre-set and cannot be removed because the input bytes
hold vital failure and diagnoses information as described in the following.
The maximum number of input and output data is limited to 244 bytes each.
Not more than 368 bytes must be exchanged in total.

8 Non-cyclical data
Non-cyclical PROFIBUS-DP services allow exchange of more data with the CPC10PB controller and the
circuit protectors. The non-cyclical access also enables direct addressing of a circuit protector on a SVS201-PWR
board.
Addressing of the data is by indication of the hardware identifier and of the index.
With ControlPlex® the hardware identifier holds the CPC10PB controller as well as the pertinent SVS201-PWR
board, the index holds the slot number and parameter index.
The index consists of the slot number and the parameter index.
