2 System overview, CTEL system
2.1 Overview of the CTEL system
The CTEL master module enables devices with an I-Port interface (I-Port devices) to be connected to
a CPX system. Up to 4 devices per CTEL master module can be integrated into the CPX system.

Fig. 2.1
A CTEL system consists of the CTEL master module and the devices that are connected to the CTEL
master module via specified I-Port connecting cables. In this way, it is possible to decentralise the ar
rangement of the devices. The compact valve terminals and I/O modules with I-Port can thus be moun
ted very close to the cylinders to be controlled. This means that the length of the air supply lines can be
reduced.
Short compressed air lines minimise the friction losses and the times for pressurising and exhausting
the tubes.
This enables smaller valves with sufficient flow to be used, thereby helping to reduce costs.

Festo – P.BE-CPX-CTEL-EN – 1601b – English 9
2.1.1 Mode of operation of the CTEL system
CTEL systems are composed of the following modules:
Modules Functions
CTEL master module – Are components of a CPX system and serve as a gateway
between CPX and I-Port modules.
– Provide connections for up to 4 valve terminals or I/O modules
per CTEL master module.
– Transmit control signals to the connected modules and monitor
their ability to function.
I-Port valve terminals – Make available various valve functions for controlling pneumatic
actuators.
– Relay plates, pressure zone separation plates and blanking
plates can also be integrated.
I-Port input modules – Make available inputs for connecting sensors and enable inter
rogation of cylinder positions, for example.
Other I-Port modules
Tab. 2.1

2 System overview, CTEL system
10 Festo – P.BE-CPX-CTEL-EN – 1601b – English
Each CTEL master module controls the data transfer to the decentralised I-Port I/O-modules in a CPX
terminal.
In principle, several CTEL master modules can be placed in a CPX terminal.
The number of CTEL master modules that can be placed in a CPX terminal is limited by the
available address space of the CPX terminal of up to 64 bytes of inputs and 64 bytes of
outputs.

Festo – P.BE-CPX-CTEL-EN – 1601b – English 11
2.2 I-Port
The CTEL master module has 4 I-Port interfaces. I-Port is an interface for the exchange of serial data for
the connection of decentralised function modules (devices) from Festo at field level. It is based on the
IO-Link technology and is compatible with it in certain areas.
The limitations compared to the IO-Link standard are, among others:
– Permanently set baud rate of 230.4 kbps.
– SIO mode is not supported.
– The maximum length of the process data is limited to 32 bytes of input data and 32 bytes of output
data.
– Only one extract of the master commands is used.
– "Plug & work" principle, configuration via IODD is not supported.
The connection type corresponds to a star topology. That means, only 1 device can be connected to
each I-Port.

Operation in accordance with the specifications is only guaranteed if original connecting
cables from Festo are used.
For operation in accordance with specifications, the maximum length of the I-Port con
necting cables must always be observed (è3.3 I-Port connecting cables).

Lights up red Device error. Several causes are possible:
– Connection to the device interrupted
– Error in the I-Port communication
Flashes red Compatibility error. Several causes are possible:
– An incompatible device is connected to the corresponding
I-Port.
– The corresponding port is deactivated, but a connected
device is recognised.

Configuration error. Several causes are possible:
– Invalid configuration (e.g. through exceeding of the available
address space)
– Device has been replaced by another device type
Tab. 2.3
Monitoring of the load voltage UVAL (PL) takes place in the devices and is passed on to the
CTEL master module.
Since all connected devices use this LED, the display of an error has priority over the dis
play “OK” (LED illuminated green).
The I-Port at which the error has occurred can be determined through the FMT/MMI using
the diagnostic messages.
Information on eliminating the displayed errors:
è5.2.2 Diagnostic/error messages by CPX error numbers.

Festo – P.BE-CPX-CTEL-EN – 1601b – English 15
2.4 Address space
The CTEL master module can make available a total of up to 32 bytes for inputs and 32 bytes for outputs.
The precise number of the I/O bytes made available depends on the requirements of the connected devices.
I/O configuration presettings
The address space that the CTEL master module makes available and assigns accordingly in the CPX
system can be configured according to different presettings (èTab. 2.4). These presettings correspond
to the selection options that are supported within the configuration files for the respective host system
(è3.6 Connection with the host system).
For the CTEL master module there are 3 presettings available for operation as a “pure input module”,
a “pure output module” and for “mixed operation”. In addition, there is also a setting for operation
without connected devices.

2.5 I/O configuration presetting
The I/O configuration presetting is implemented via the DIL switches on the left side of the CTEL master
module, directly below the housing cover. These are only accessible if the module is removed from
the CPX system.

The I/O mode of the CTEL master module is set via DIL switch group 1 (èTab. 2.5). The setting of
the I/O length, i.e. the determination of available I/O bytes per I-Port, is implemented via DIL switch
group 2 (èTab. 2.6).

3.1 General instructions for installation
Warning
Personal injury or material damage may result due to accidental movement of the con
nected actuators and uncontrollable movements of loose tubing.
Before carrying out mounting, installation and maintenance work, switch off the follow
ing:
– Compressed air supply
– Operating voltage supply for electronics/sensors (UEL/SEN)
– Load voltage supplies for outputs/valves (UOUT/UVAL)
Note
Electrostatically sensitive devices
 Do not touch any components.
 Observe the handling specifications for electrostatically sensitive devices.
Note
 Handle all modules and components carefully.
 Comply with the specified torques.
Information on mounting the CPX terminal can be found in the CPX system description
(èP.BECPXSYS…).

3 Installation
Festo – P.BE-CPX-CTEL-EN – 1601b – English 19
3.2 Mounting and dismantling
The CTEL master module is designed for mounting in a CPX interlinking block (èFig. 3.1).
Warning
The CTEL master module must always be mounted/dismantled in a de-energised state.
 Disconnect the corresponding CPX terminal completely from the related power sup
ply or switch it off.
Note
The CTEL master module does not have a separate connection block, but is designed as
a complete unit.
The desired I/O configuration presetting should be implemented and checked via the DIL
switches (è2.5) before the CTEL master module is mounted, as these switches can no
longer be reached after mounting.

3 Installation
20 Festo – P.BE-CPX-CTEL-EN – 1601b – English
Mounting
Mount the module as follows:
1. Check seal and sealing surface.
2. Insert module into the interlinking block. Make sure that the corresponding slots with the contacts
on the bottom of the module lie above the contact rails.
3. Push the module carefully and without tilting into the interlinking block up to the stop.
4. Screws should only be tightened by hand. Screws must be set so that the self-cutting threads can
be used.
5. Tighten screws (tightening torque 0.9 … 1.1 Nm).
Dismantling
Dismantle the module as follows:
1. Loosen the screws.
2. Pull the module carefully and without tilting away from the contact rails of the interlinking block.
3.3 I-Port connecting cables
Note
Operative malfunction due to impermissible cabling.
 To connect the I-Port devices to the CTEL master module, only use the special I-Port
connecting cables from the Festo catalogue (èwww.festo.com/catalogue)
 Observe the maximum length of 20 m for the I-Port connecting cables.
You will then avoid errors in data exchange between the CTEL master module and the
connected devices.
For an operation with tool change, there are special specifications that must be observed
in designing the connection lines. The interface in the connecting cable must be construc
ted in such a way that, when establishing the connection, the contacts of the power sup
ply for the device (24 V and 0 V UVAL) are connected first. Otherwise, a short circuit may
be reported temporarily through the voltage present on the C/Q cable when the connec
tion is established.
