2. GENERAL DESCRIPTION
CPC12 - transparency through webserver and
fieldbus connection
The requirements of machine and plant construction
regarding machine uptime and a consistently high
production quality are increasing. Stable processes
are based on a reliable and transparent DC24V pro-
tection and power distribution system.
E-T-A’s CPC12 bus controller has a separate DC24V
power supply and allows independent supply of the
circuit protectors. It records all status information and
measuring values. These data are visualised with the
internal webserver. Via the field bus interface, the
data are also made available to the superordinate
control systems.
E-T-A’s REX12D system in combination with the
CPC12 bus controller was designed specifically for
the requirements of the machine construction and
process control industry. The REX12D modular
power distribution system combined with the CPC12
bus controller meets all requirements.
• Maximises plant and machine uptime
through clear failure detection, high
transparency and remote diagnosis
• Saves space through a slim design of
the circuit protectors and the potential
modules
• Increases flexibility of system plan-
ning through many different modules
meeting the demands of DC24V power
distribution

3. CONNECTION WITH THE WEBS-
ERVER
As soon as the electrical installation of the
ControlPlex® system is completed, an Ethernet
connection can be established via X1 interface
on the CPC12 bus controller.
To do this, the adapter options must first be set to the
standard IP range 192.168.1.XXX (for example
192.168.1.254).
1. Under Windows Settings the submenu "Network
and Internet" is selected
2. Clicking on "Change adapter options" opens the
"Network connections" window
3. Double-click on the current Ethernet connection to
open the "Status of WLAN" window
4. Clicking on "Properties" opens another window in
which the "Internet Protocol, Version 4" is selected

7 7
5. Clicking on "Properties" opens a new window in
which the item "Use the following IP address" is se-
lected, the corresponding address is entered and
confirmed with "OK“
After the network settings have been adjusted, the
webserver of the CPC12 can now be accessed via a
standard web browser. In the following example, the
Microsoft Edge browser was used. In addition, the
browser variants Chrome and Mozilla Firefox in the
latest versions are possible. Only these variants are
checked and available for the webserver. All other
browsers are not supported.
To call the webserver of the CPC12, the default IP
address 192.168.1.1 must be typed in the upper
search field of the web browser and then confirmed.

4.1.3.3 Reset Controller
After selecting the function, the CPC12 bus controller
is reset and restarted. This resets the IP address of
the webserver on port X1 to the default address
192.168.1.1. The language setting is also reset to
English and the user management is reset. (The
function is only possible in Admin mode).
4.1.3.4 Edit Users
After selecting the function, a new window opens with
the overview of the current administrators and users
of the system. New users can be created and exist-
ing ones can be edited and deleted (The function is
only possible in Admin mode).

After pressing the "Add User" button, a window with
possible settings for the new account will open.
Please note the role of the account!
In the admin mode all functions are available.
In the user mode it is only possible to switch the
channel on or off with an already deactivated lock
command. Furthermore, the statistics data and the
error counter can be reset.
4.1.3.5 Firmware-Update
After selecting the "Firmware Update" function, an
Explorer window opens to access the location of the
firmware file. The latest firmware updates are availa-
ble in the download portal of the ControlPlex® sys-
tems via the E-T-A homepage.

After the file has been selected, the firmware update
begins. Attention: The file can only be loaded into the
controller in Admin mode. Otherwise, the file will be
declared as not valid.

4.1.4 Commands
By pressing the Commands button a drop-down
menu opens. This includes various functionalities,
which are described below:
4.1.4.1 Turn all Devices off
By selecting this function, all electronic circuit break-
ers can be turned off. This function is only possible if
there is only one connection to the webserver and
the "Lock" function of the circuit breaker is set to the
"OFF" status (the function is only possible in Admin
mode and without connection to the fieldbus).
4.1.4.2 Reset Devices
By selecting this function, after a short circuit or over-
load trip, all circuit breakers will be reset after the
fault has been solved (the function is only possible in
Admin mode and without connection to the fieldbus).

4.1.4.3 Enable Power Save
By selecting this function, the LED indicators on the
electronic circuit breaker are dimmed or brightened
again (The function is only possible in Admin mode).
4.1.4.4 Batch Edit Devices
Selecting this function opens another window with an
overview page of all configured parameters. First, a
pop-up window asks whether the existing parameters
of the current system should be loaded (Download
Config), an already saved configuration file should be
loaded (Load Config File) or a new standard configu-
ration should be started (Continue with Factory Set-
tings).
The table displayed in the window consists of the fol-
lowing parameters:

The upload of the configuration to the CPC controller
is only possible with admin rights.
4.1.4.5 Adopt Device Types
With the function "Adopt Device Types" selected, the
currently used structure is automatically read out
from the used hardware. The circuit breakers must
therefore no longer be configured manually. (The
function is only possible in Admin mode).
4.2 Status Bar
Below the menu bar, the status of the various elec-
tronic circuit breakers can be evaluated immediately
using the boxes in the area "Device". This box is di-
vided into two areas. By clicking on these areas, it is
also possible to navigate the circuit breaker overview
page to the different parts of the system. The cur-
rently displayed area is shown with a blue line below
it.
If the system is operating, the colour is green. If there
is a warning or an error, it will be highlighted with the
colours orange or red. A gray filled rectangle means
that the circuit breaker was switched off manually at
the device. If the rectangle is only outlined, no device
is connected.

5. CIRCUIT BREAKER OVERVIEW
After the functionality of the system has been de-
scribed in the previous chapter, the middle overview
of the interface will be discussed now. This shows
the various electronic circuit breakers lined up. Each
channel shows the output voltage and current as well
as different status messages.
The upper rectangle contains the currently set cur-
rent rating. Depending on the recent switching state
or message, the box changes its colour. Gray = Off,
Green = On, Yellow = Warning, Red = Trip
Below that, different points clarify the status of the
channel. These can also light up in the colours green,
yellow, red.
The blue line above and below illustrates the se-
lected circuit breaker.

6. CIRCUIT BREAKER
FUNCTIONALITY
The last third of the overview page displays addi-
tional information and functions for the selected cir-
cuit breaker. Three different tabs can be selected on
the left-hand side. These are explained below:
6.1 Parameter
The first tab displays general information about the
circuit breaker, such as the serial number and the
hardware and software version. Furthermore, the last
error reason can be read out.
The possible parameters that can be set have al-
ready been explained in the "Batch Edit De-vice"
function. The different input fields can be adjusted by
the integrated arrow keys. If the required value is
reached, the new setting can be loaded into the de-
vice via the "Write Parameter" button.
The "Restore Factory Settings" button resets all pa-
rameters to the factory settings.
The "Lock" selection option blocks switching the cir-
cuit breaker off or on from the software.
As soon as the function is set to status "OFF", the cir-
cuit breaker can be switched. As soon as the circuit
breaker is switched off from the software, the hard-
ware LED at the channel shows the colour orange.
Attention:
The role of the logged in account has to be checked.
The differences between the Admin and the User
mode are explained in chapter 4.1.3.4.
In addition, the function for resetting a circuit breaker
and switching it on and off is not available with a con-
nected fieldbus interface. The PLC software has a
higher priority.
Furthermore, control and writing via the webserver
can be deactivated via the PLC software (Configura-
tion data of the CPC12 - Byte 0 Bit 0)!
