The safety chapter explains the safety symbols used and their meanings. They contain fundamental safety
instructions that are essential for the avoidance of personal injuries and damage to property.
Exclusion of liability
Beckhoff shall not be liable in the event of non-compliance with this documentation and thus the use of the
devices outside the documented operating conditions.
2.1 Description of safety symbols
The following safety symbols are used in these operating instructions. In order to avoid personal injuries and
damage to property, read and follow the safety and warning notices.
Warning of personal injuries:
DANGER
Disregarding the safety notice will lead to death or serious injuries.
WARNING
Disregarding the safety notice may lead to death or serious injuries.
CAUTION
Disregarding the safety notice may lead to minor injuries.
Warning of damage to property:
NOTE
Disregarding the notice may lead to damage to property.
2.2 Intended use
The CP29xx multi-touch built-in Control Panel is designed for industrial applications in machine and system
engineering. A display with multi-finger touch screen is installed in an aluminum housing. The control panel
is installed in the front of control cabinets.
The DVI/USB extension technology integrated in the CP29xx-0000 Control Panel enables the panel to be
located up to 50m away from the PC.
The CP-Link 4 technology integrated in the CP29xx-0010 Control Panel enables the panel to be located up
to 100m away from the PC via a CP-Link 4 cable with optionally integrated or separate 24V power supply,
depending on the transmitter module.
The front of the control panel is designed for an IP65 working environment. It offers full protection against
contact and against water jets (nozzle) from any angle and against dust. The rear of the control panel is
designed for an IP20 working environment. This involves finger protection and protection against solid
foreign objects up to 12.5 mm. There is no protection against water. The specified limits for technical data
must be adhered to.
The control panel can be used within the documented operating conditions.
Improper use
Do not use the device outside the documented operating conditions.

For your safety
CP29xx 7Version: 3.6
2.3 Fundamental safety instructions
The following safety instructions must be observed when handling the device.
Application conditions
• Do not use the device under extreme environmental conditions. Protect the back of the device from
dust, moisture and heat and keep the ventilation slots clear.
• Never use the device in potentially explosive atmospheres.
• Do not carry out any work on the device while it is live. Always switch off the supply voltage for the
device before mounting it, replacing device components or rectifying malfunctions.

security concept for the operation are necessary to protect the respective plant, system, machine and
networks against cyber threats. The products sold by Beckhoff are only part of the overall security concept.
The customer is responsible for preventing unauthorized access by third parties to its equipment, systems,
machines and networks. The latter should be connected to the corporate network or the Internet only if
appropriate protective measures have been set up.
In addition, the recommendations from Beckhoff regarding appropriate protective measures should be
observed. Further information regarding information security and industrial security can be found in our
https://www.beckhoff.com/secguide.
Beckhoff products and solutions undergo continuous further development. This also applies to security
functions. In light of this continuous further development, Beckhoff expressly recommends that the products
are kept up to date at all times and that updates are installed for the products once they have been made
available. Using outdated or unsupported product versions can increase the risk of cyber threats.

3.2.4 USB Extended input
The CP29xx-0000 Control Panel has a USB Extended input (X105) in the form of an RJ45 socket. The
control panel is connected to the CU8801 USB-to-USB extended converter box via the interface. The
connection is made via a standard RJ45 cable, not crossed. The interface transmits USB 2.0 at 480Mbit/s.
The socket does not represent an Ethernet port.
To realize a distance of 50m without hubs, USB Extended converts the USB signal so that it can be
transmitted via a 50m CAT-5 cable. In the control panel the signal is converted back to USB.

3.2.5 DVI Extended input
The CP29xx-0000 Control Panel has a DVI Extended input (X106). It is used to transmit the graphics signal
from the industrial PC to the control panel.
The graphics signal is transferred directly via a DVI cable over a distance of 50m max. Such a cable length
leads to strong distortion of the graphics signal on arrival at the control panel. A signal processor is used in
the control panel to fully restore the DVI signal. The industrial PC requires a conventional DVI output.

The CP29xx-0010 Control Panel has a CP-Link 4 input (X104) in the form of an RJ45 socket. This is not an
Ethernet port. Via the interface, the control panel can be connected to an industrial PC at a distance of up to
100m. The connection can be made either directly with an industrial PC with a corresponding PCIe module
or indirectly via an intermediate transmitter box.

On an industrial PC with PCIe module, CP-Link 4 is available as a Two Cable Display Link. The control panel
can be connected directly to the industrial PC via the module. USB 2.0 (100Mbit/s) and DVI are transmitted
together via a CP-Link 4 cable. For the power supply of the CP29xx-0010 you have to connect an additional
power supply (see Fig. 12).

CP-Link 4 with transmitter box
If the industrial PC is not equipped with a PCIe module, a transmitter box is required for connecting a
CP29xx-0010. The CU8802 transmitter boxes (Two Cable Display Link) and CU8803 (One Cable Display
Link) are available for this purpose.
When installing the CP29xx-0010 with the CU8802 transmitter box, the industrial PC is connected to the
transmitter box via USB and DP/DVI. The transmitter box is then connected to the control panel via the CP-
Link 4 connection of the transmitter box using a CP-Link 4 cable. USB and DVI are transmitted together via
this cable. For the power supply of the CP29xx-0010 you have to connect an additional power supply (Two
Cable Display Link). Fig. 13 shows the wiring with the CU8802.

When installing the CP29xx-0010 with the CU8803 transmitter box, the industrial PC is likewise connected to
the transmitter box via USB and DP/DVI. The transmitter box is then connected to the control panel via the
CP-Link 4 connection of the transmitter box using a CP-Link 4 cable. With this box, USB, DP/DVI and power
supply can be transmitted together via the cable (One Cable Display Link). Accordingly, you do not have to
connect an additional power supply to the CP29xx-0010. Fig. 14 shows the wiring with the CU8803.
