2.2 IO-Link
The IO-Link network system serves to exchange serial data from decentralised function modules
(devices) at the field level.
The electrical interface CPX-CTEL-2-M12-5POL-LK has 2 interfaces (ports) that, with few limitations,
support connection of IO-Link devices.
The limitations compared to the IO-Link standard are:
– the SIO mode is not supported.
– the process data length of the inputs and outputs is limited to 32 bytes (2 x 16) each.
– the driver strength on the C/Q line is limited to 250 mA.
The connection type corresponds to a start topology, that means, only 1 device can be connected to
each port.

2.4 Addresses
The module can make available a total of up to 16 bytes for inputs and 16 bytes for outputs per port.
The precise quantity of the I/O bytes made available depends on the selected configuration presetting.
2.4.1 I/O configuration presetting
The address space that the module makes available and assigns accordingly in the CPX system can be
configured according to various presettings (Tab. 2.3).
These presettings correspond to the selection options that are supported within the configuration files
for the respective host system (3.6 Connection with the host system).

• Donottouchanycomponents
• Observe the handling specifications for electrostatically sensitive devices.
They will help you avoid damage to the electronics.
Note
• Handle all modules and components carefully.
• Comply with the specified torques.
Information about mounting of the CPX terminal can be found in the CPX system descrip-
tion (P.BE-CPX-SYS-...).

3 Installation
16 Festo – P.BE-CPX-CTEL-LK-EN – 1405NH – English
3.2 Mounting/dismounting
The module is designed for mounting in a CPX interlinking block (Fig. 3.1).
Warning
Mounting /dismounting of the module must always take place in a de-energised status.
• Disconnect the corresponding CPX terminal completely from the related power sup-
ply or switch it off.
Note
The module does not have a separate connection block, but is designed as a complete
unit.
Before the module is mounted, it makes sense to set or check the desired configuration
with the help of the DIL switches, since they can no longer be reached after mounting
(2.4.2 Setting of the I/O configuration presetting).

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 existing self-cutting
threads can be used.
5. Tighten the screws with a TORX screwdriver, size T10 with 0.9 ... 1.1 Nm.
Dismantling
Dismantle the module as follows:
1. Loosen screws with a TORX screwdriver, size T10.
2. Pull module carefully and without tilting away from the contact rails of the interlinking block.
3.3 Connecting cables
Note
Malfunction due to impermissible cabling.
• If possible, use only specified connecting cables from Festo to connect the devices
to the module (www.festo.com/catalogue).
• Observe the maximum length of 20 m for the connecting cables used to connect the
devices.
You will then avoid errors in data exchange between the module and the connected
devices.
Replacement of devices during operation (tool change mode).
The interface of the connecting cable must be designed so that, when creating the con-
nection, the contacts of the power supply (PS) are energised first.
Otherwise, a short circuit might be reported temporarily through the voltage present on
the C/Q cable when the connection is created.

3 Installation
18 Festo – P.BE-CPX-CTEL-LK-EN – 1405NH – English
3.4 Connection of devices
A total of up to 2 IO-Link devices can be connected to the module. These are connected to the module
through specified connecting cables (3.3 Connecting cables).
If an error occurs on several devices simultaneously, only the diagnostic or error message
of the device with the highest priority is passed on
(5.2.1 Priorities of the diagnostic/error messages).
After this error is eliminated, the error with the next lowest priority is displayed. The prior-
ity of the connected devices results from the number of the used port (X1 or X2). The
device at X1 has the highest, the device at X2 the lowest priority in representing a dia-
gnosticorerrormessage.
With use in a CPX terminal of more than one of the modules described here, the module that is moun-
ted closer to the CPX bus node has the higher priority.
The result of this is that devices with process-critical functions must be connected to the
port with the higher priority.
Connect devices:
1. Connect devices with the connecting cables to the module corresponding to their priority (see
above).
2. Tightly screw the plug of the connecting cable to the socket of the module. In this way, the electrical
contact is guaranteed.
3. With the inscription labels (type IBS 6x10 or IBS 9x20), mark the port to which the device is connec-
ted. In this way you can avoid confusion during later repair and maintenance work.

3 Installation
Festo – P.BE-CPX-CTEL-LK-EN – 1405NH – English 19
3.5 Connecting the power supply
Take the following aspects into consideration when installing a CPX system with the module described
here:
– power supply (3.5.1 Power supply)
– current consumption (3.5.2 Determining the current consumption)
– formation of voltage zones (CPX system description P.BE-CPX-SYS-…).
Note
• Observe the notes on earthing the devices in the description for the respective
device.
Recommendation:
• When implementing an emergency-off function, guide the load voltage of the corresponding actuat-
or technology separately.
Note
• Check whether a pressure switch-off on the machine or system is also necessary in
case of emergency off.
3.5.1 Power supply
The CPX terminal has 3 different conductors:
–U
EL/SEN:
Power supply (PS) for internal electronics of the module and connected devices
–U
OUT:
Load voltage supply for digital output modules
–U
VAL:
Load voltage supply (PL) for valve terminals, output modules or other consumers.
The load voltage supply U
OUT
is not used by the module described here.
Additional information on power supply and formation of voltage zones (CPX system
description P.BE-CPX-SYS-…).
Note
Malfunctions due to insufficient power supply.
• Supply of the load voltage supply U
VAL
must be sufficiently dimensioned to be able
to supply the connected actuators.
• Observe that, dependent on the respective length of the connecting cable and cur-
rent consumption of the connected device, a voltage drop results between the mod-
ule and device.
Therefore, when connecting cables > 5 m are used, the operating voltage supply
U
EL/SEN
should not be fallen below by more than 10 %.
• The total current requirement of the CPX terminal and the connected devices as well
as the limit values for the maximum current intensities must be taken into account in
the design of the power supply (3.5.2 Determining the current consumption).

3 Installation
20 Festo – P.BE-CPX-CTEL-LK-EN – 1405NH – English
3.5.2 Determining the current consumption
The current consumption of the module depends on the number and type of connected devices.
Recommendation:
• Use a regulated power supply
• When selecting the power supply unit, check whether it has sufficient output.
Calculate the total current consumption, if necessary.
Calculation:
• Use the following table to calculate the total current consumption (Tab. 3.1).
• Refer to the corresponding technical data for the current consumption of the devices.
Note
• Select a power supply unit which provides sufficient power for later extensions.
• Observe the notes regarding selection of the power supply unit in the CPX system
description (P.BE-CPX-SYS-…).
• If output modules with a separate load voltage connection are used, take into account
the corresponding current consumption when selecting a power supply unit.
