2.1 Overview CTEL system

Festo can assist you in solving your automation task at the machine level with the aid of valve terminals
and I/O modules.
The CTEL master module from Festo permits connection of devices with an I-port interface (I-port
devices) 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 master
module over specified I-port connecting cables. In this way, it is possible to decentralise the arrange
ment of the devices. The compact valve terminals and I/O modules with I-port can thus be mounted
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.

2 System overview, CTEL system

2.1.1 Mode of operation of the CTEL system

CTEL systems are composed of the following modules:

Modules

Functions

CTEL master – Are components of a CPX system and serve as gateway

between CPX and I-port modules.

– Provide connections for up to 4 valve terminals or I/O modules

per 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

interrogation of cylinder positions, for example.

Other I-port modules

Tab. 2.1

Festo – P.BE-CPX-CTEL-EN – 1411a – English 9

2 System overview, CTEL system

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.

2 System overview, CTEL system

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 over IODD is not supported.
The connection type corresponds to a star topology. That means, only 1 device can be connected to
each I-port.

Monitoring of the load supply voltage (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.

2 System overview, CTEL system

2.4 Addresses

The CTEL master module can make available a total of up to 32 bytes for inputs and 32 bytes for out
puts. The precise amount of the I/O bytes made available depends on the requirements of the connec
ted devices or of the correspondingly selected operating mode.

2.4.1 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 13 different presettings (è Tab. 2.4). These presettings corres
pond to the selection options that are supported within the configuration files for the respective host
system (è 3.6).
There are 4 presettings available in each case for operation as “pure input module”, “pure output mod
ule” and for “mixed operation”.
In addition, there is a configuration for operation without connected devices.

(through the user) or automatically (through the module itself), dependent on the operating mode.

Festo – P.BE-CPX-CTEL-EN – 1411a – English 15

2 System overview, CTEL system

2.5 Operating modes (selection of the I/O configuration presetting)

Users can determine the I/O configuration presettings used by the CTEL master module themselves
(operating mode “Manual configuration”) or have it determined automatically through the module
(operating mode “Automatic configuration”).
Selection of the operating mode and the setting for the manual configuration takes place via the DIL
switches on the left side of the module, directly below the housing cover. These are only accessible if
the module is removed from the CPX system.

Fig. 2.6

The operating mode of the CTEL master module (automatic configuration or manual configuration) is
determined with the DIL switches 1.1 and 1.2 (è Tab. 2.5).
With the DIL switches 2.1 and 2.2, the I/O length, i.e. the available I/O bytes per I-port, are determined
in the manual configuration (è Tab. 2.6). In automatic configuration, the setting of these two switches
is not relevant.

16 Festo – P.BE-CPX-CTEL-EN – 1411a – English

2 System overview, CTEL system

In the manual configuration, the established I/O length always applies for all 4 I-ports
(max. 8 bytes per I-port).
In the case of automatic configuration, the I/O length for each I-port is determined indi
vidually and this value is used to select the appropriate or next highest configuration
preset (è 2.4.1 or 4.1.2).

They will help you avoid damage to the electronics.

Note

 Handle all modules and components carefully.
 Comply with the specified torques.

You can obtain information on mounting the CPX terminal in the CPX system description
(è P.BECPXSYS…).

18 Festo – P.BE-CPX-CTEL-EN – 1411a – English

3 Installation

3.2 Mounting and dismantling of the module

The CTEL master module is designed for mounting in a CPX interlinking block (è Fig. 3.1).

Warning

Mounting/dismantling of the CTEL master module must always take place in a de-ener
gised 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.

Before the CTEL master module is mounted, the desired operating mode/configuration
should be set or checked with the help of the DIL switches (è 2.5), since they can no
longer be reached after mounting.

3 Contact rails
4 Screws

3 Installation

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 I-port connecting cables

Note

Malfunction due to impermissible cabling.
 To connect the I-port devices to the CTEL master module, use only the special I-port

connecting cables from Festo (è A.3).

 The maximum length of the I-port connecting cables used to connect the I-port

devices is limited to 20 m.
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 constructed so that, when creating the
connection, the contacts of the device supply voltage (24 V PS and 0 V 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.

20 Festo – P.BE-CPX-CTEL-EN – 1411a – English

3 Installation

3.4 Connection of the devices to the CTEL master module

A total of up to 4 I-port devices can be connected to one CTEL master module.
The devices are connected via Festo I-port connecting cables to the CTEL master module
(è 2.1 Overview CTEL system and 3.3 I-port connecting cables).

If an error occurs on several devices simultaneously, only the diagnostic/error message of
the device with the highest priority is passed on
(è 5.2.1 Priorities of the diagnostics/error messages).
After this error is eliminated, the error with the next lowest priority is displayed.
The priority of the connected devices results from the number of the used I-port. The
device at I-port 1 has the highest, the device at I-port 4 the lowest priority in representing
a diagnostic/error message.
If the CTEL master is configured to “I/O mixed operation”, diagnostics/error messages
from inputs have priority over diagnostics/error messages from outputs.

With use of more than one CTEL master module in a CPX terminal, the module that is mounted 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
I-ports as high a priority as possible.

Connect devices:

1. Connect devices with the I-port connecting cables to the CTEL master module corresponding to their
priority (see above).

2. Tightly screw the plug of the I-port connecting cable to the socket of the CTEL master module by
using the union nut. In this way the electrical contact is guaranteed.

3. With the inscription labels (type IBS 6x10 or IBS 9x20), mark the I-port to which the device is con
nected. In this way you can avoid confusion during later repair and maintenance work.

Festo – P.BE-CPX-CTEL-EN – 1411a – English 21

3 Installation

3.5 Connecting the power supply

Take the following aspects into consideration when installing a CPX system with the CTEL master mod
ule:
– Power supply (è 3.5.1 Power supply)
– Current consumption (è 3.5.2 Determining the current consumption)
– Formation of voltage zones (è CPX system description P.BE-CPX-SYS-…)

Note

 Observe the instructions on earthing the I-port devices in the description for the

relevant module.

Recommendation:
 When implementing an EMERGENCY-OFF function, guide the load voltage for the corresponding

actuator technology separately.

Note

 Check whether pressure switch-off is also necessary for an EMERGENCY-OFF func

tion on your machine/system.

3.5.1 Power supply

The CPX terminal has 3 different conductors:
–U
–U
–U

Power supply (PS) for internal electronics of the module and connected devices

EL/SEN:

Load voltage supply for digital output modules

OUT:

Load voltage supply (PL) for valve terminals, output modules or other consumers.

VAL:

The load voltage supply U

is not used by the module described here.

OUT

Additional information on power supply and formation of voltage zones (è CPX system
description P.BE-CPX-SYS-…).

Note

Malfunctions due to insufficient power supply.
 Supply of the load voltage supply U

must be sufficiently dimensioned to be able

VAL

to supply the connected actuators.

 Observe that, dependent on the respective length of the I-port connecting cable and

current consumption of the connected I-port device, a voltage drop results between
the CTEL master module and the device.
Therefore, when connecting cables > 5 m are used, the operating voltage supply
U

should not be fallen below by more than 10 %.

EL/SEN

 The total current requirement of the CPX terminal and the CTEL system, as well as

3.5.2 Determining the current consumption

The current consumption of a CTEL system depends on the number and type of connected I-port
devices.

Recommendation:
 A regulated power supply.
 When selecting the power supply unit, check whether it has sufficient output. Calcu

late the total current consumption, if necessary.

Calculation

 Use the following table to calculate the total current consumption (è Tab. 3.1).
 Please refer to the relevant technical data for the current consumption of the I-port devices.

Note

 Select a power supply unit which provides sufficient output for subsequent expan

sions to the CTEL system.

 Observe the notes regarding selection of the power supply unit in the CPX system

description (P.BE-CPX-SYS-…).

 If you are using I-port output modules with a separate load voltage connection, take

into account the corresponding current consumption when selecting a power supply
unit.

3.6 Connection with the host system

For the required connection between the CTEL master module in the CPX terminal and the higher-order
host system, it is required that the configuration file entry that corresponds to the current configuration
presetting of the CTEL master module is selected in the host system.
Only in this case is the CTEL master module correctly recognised when the system is run up.
Otherwise, no communication can be built up and no diagnostics/error message is output. The possible
configurations correspond to the description in section 2.4.1 I/O configuration presettings.

3.7 Ensuring protection class IP65/67

Note

To comply with protection class IP65/IP67:
 Seal unused I-ports with corresponding protective caps (accessories, not included in

the scope of delivery (è A.3)).

4.1 Description of the operating modes

The behaviour of the CTEL system is fundamentally influenced by the set operating mode. The following
criteria are particularly decisive for the selection of the operating mode:
– Type of installation (permanent or flexible)
– Available address space (large or strongly limited)

4.1.1 Manual configuration (tool change mode)

Benefits

Manual configuration of the I/Os offers the possibility to replace the connected I-port devices during
operation. I/O configuration and I/O length are determined together for all I-ports. Each I-port device
that corresponds to this configuration can be connected during operation.

For permanently established I/O lengths, observe that the connected modules must not
exceed the set I/O lengths. Otherwise, an I-port configuration error is output
(è 5.7.2 “Manual configuration” operating mode).

Select manual configuration

For manual configuration, it must be determined through the DIL switches S1.1 and S1.2 whether the
CTEL master module at all 4 I-ports makes available only inputs (pure input module), only outputs (pure
output module), or inputs and outputs (mixed operation) (è Tab. 2.5).

I/O lengths

The I/O length is determined together for all 4 I-ports through the DIL switches 2. An I/O length of
4 bytes per I-port corresponds to a setting of 16 bytes, for example (è Tab. 2.6).
Example:
The following devices should be connected to the CTEL master module at system start:
– Output module with 16 outputs (2 bytes O)
– Input module with 8 inputs (1 byte I)
– Valve terminal with 32 outputs (4 bytes O)
– Input module with 16 inputs (2 bytes I)
Since devices with inputs and outputs should be connected, the CTEL master module must be set to
“mixed operation” (switch S1.1 and S1.2 to “ON”).

The I/O length results from the device with the highest I/O requirements, in this case
4 bytes for the valve terminal.

Since no individual I/O lengths are possible with the manual configuration, an I/O length of 4 bytes per
I-port, that is 16 bytes (for all I-ports together) must be selected (switch S2.1 to “OFF”, S2.2 to “ON”).
The configuration presetting selected through this is thus 16 bytes I/16 bytes O.

26 Festo – P.BE-CPX-CTEL-EN – 1411a – English

4 Commissioning

In cases in which the reserved address space is not completely used by the connected devices, this
results in input and output addresses (channels) to which no device input or output is assigned.

Unused channels

Input channels to which no device input is assigned are automatically set to the value “0” in the CPX
system.
Output channels to which no device output is assigned are ignored in data transmission.

Sequence at system start

At the start of the system, the CTEL master module checks all I-ports for connected devices and their
agreement with the selected configuration presetting.

Communication with the host system

To make a connection set-up between the CPX terminal and higher-order controller possible, the manu
al configuration presetting of the CTEL master module must agree with the respective entry of the cor
responding fieldbus configuration file (è 3.6 Connection with the host system).

Festo – P.BE-CPX-CTEL-EN – 1411a – English 27

4 Commissioning

4.1.2 Automatic configuration

Benefits

No setting by the user is necessary in automatic configuration of the I/Os. At system start, the CTEL
master module automatically determines the suitable I/O configuration presetting
(è 2.4.1 I/O configuration presettings). The precise sum of the required I/Os are used for this so that a
smaller configuration presetting can be selected compared to the manual configuration.

Select automatic configuration

To operate the CTEL master module with the “Automatic configuration” operating mode, the DIL
switches S1.1 and S1.2 must be set to “OFF”. The position of switches S2.1 and S2.2 is not relevant
thereby.

Sequence at system start

– Interrogation of the I-ports

At system start, all four I-ports are interrogated and the number of I/Os of all connected devices is
determined to the precise byte.

– Selection of the configuration presetting

The sum of the determined I/Os is compared by the software to the available configuration preset
tings (è 2.4.1 I/O configuration presettings). The suitable or next higher configuration presetting is
selected.
Example:
The following devices are connected to the CTEL master module at the system start:
– Output module with 16 outputs (2 bytes O)
– Input module with 8 inputs (1 byte I)
– Valve terminal with 32 outputs (4 bytes O)
– Input module with 16 inputs (2 bytes I)
Sum of the required I/O bytes: 3 bytes I/6 bytes O

Selection of the configuration presetting:

Sum of I/O bytes

Configuration presettings

3 bytes I/6 bytes O …

32 bytes I/0 bytes O
8 bytes I/8 bytes O

16 bytes I/16 bytes O

…

28 Festo – P.BE-CPX-CTEL-EN – 1411a – English

4 Commissioning

Distribution of the assigned addresses to the I-ports is individually possible in the auto
matic configuration. That is, an individual I/O length between 1 byte and 32 bytes can be
assigned to each I-port for determination of the sum of the I/O bytes.
But the sum of the bytes available in total remains 32 bytes. That means, if the 32 bytes
are issued to an I-port, no more I/Os are available for the other three I-ports.

Communication with the host system

To make a connection set-up between the CPX terminal and higher-order controller possible, it must be
ensured that the automatically determined configuration presetting of the CTEL master module agrees
with the respective entry of the corresponding fieldbus configuration file (è 3.6).

4.1.3 Address assignment in the CPX system

I/O bytes are assigned in the CPX system corresponding to the selected configuration presetting.
The assigned address spaces are thereby filled “from below”, that is, the starting point is the least
significant address (LSB). The unused MSBs expire.
The distribution of the device addresses to the address space of the CTEL master module in the ex
amples from sections 4.1.1 and 4.1.2 would look as follows:

Through the possibility of automatic I/O configuration and exact-byte issuing of an indi

reduced compared to the manual configuration.

In the example, the assigned address space in the automatic configuration is 8 bytes I/8 bytes O
(12.5 % of the entire address space in the CPX system). To use the same devices in the manual config
uration, 16 bytes I/16 bytes O are needed (25 % of the total address space in the CPX system).

4.2 Procedure for commissioning

In order to avoid connecting and configuration errors, commissioning in steps is required.
Proceed as follows:

1. Check the CTEL master module and the connected I-port devices
(è 4.3 Preparing the CTEL system for commissioning).

2. Determine the configuration presetting (è 2.4.1 I/O configuration presettings).

3. If required: Parameterisation of the CTEL master module and the I-port devices (è 4.6 Parameter).

4. Check power supplies (è 3.5 Connecting the power supply).

5. Commissioning of the entire system (è description of the specific CPX bus node).

4.3 Preparing the CTEL system for commissioning

Note

 Do not connect the CPX terminal to a higher-order controller yet to prepare for com

missioning.
You will thus avoid addressing faults which may occur in various fieldbus systems when
address ranges are modified during operation.

The host system integration of the CTEL master module might have to take place through
a device description file, dependent on the CPX fieldbus node used. Corresponding de
scription files: è www.festo.com/sp.

4.3.1 Check the CTEL master module and the connected I-port devices

 Check, if necessary, the position of the DIL switches to guarantee the desired operating mode and

configuration presetting.
 Check the CTEL master module for a tight fit in the interlinking block.
 Check whether the connected I-port devices correspond to the entry of the configuration file on the

host system (è 3.6 Connection with the host system).
 Check whether the connected I-port devices are distributed to the I-ports corresponding to their

priority for the diagnostic/error messages (è 5.2.1 Priorities of the diagnostics/error messages).
 Check whether the current consumption of the connected I-port devices and the other CPX modules

corresponds to the specifications and limit values (è 3.5 Connecting the power supply).
 Check the power supply connections at the interlinking blocks.

4.4 Behaviour in case of malfunctions in operation

If there is a malfunction on an I-port during operation, e.g. broken cable, etc., this will be indicated by
flashing or illumination of the display LED (X1 ... X4) of the corresponding I-port on the CTEL master
module.
The behaviour of the affected device is dependent on the device type.
Moreover, additional diagnostic information of the module is available and can be called up both via the
fieldbus used as well as via the Festo Maintenance Tool (CPX-FMT) or the operator unit (CPX-MMI).

Detailed instructions on the diagnostic functions of the CTEL master module:
è 2.3 Display components, è 5.1 Summary of diagnostics options.

4.4.1 Start of the CPX terminal with system setting “Stored parameters”

If the start setting “Stored parameters” is configured in the system settings of the CPX
terminal instead of “Standard parameters”, the current assignment of the I/O address
space of all modules remains permanently stored in the CPX terminal.

Particularly if the CTEL master module is operated in the automatic configuration, the following must
be observed:
In case of a change of the I/O assignment of the I-ports (e.g. through connection/disconnection of
devices or wire break in the I-port connecting cable) in combination with a restart of the CPX terminal,
the error “Incorrect I/O length” is reported, since the currently existing I/O configuration of the CTEL
master differs from the configuration stored in the CPX terminal.

4.5 Notes on operation

Warning

Accidental interchange of the connected I-port devices.
Caution with subsequent modification of the I-port assignment:
 Make sure that devices are not separated from an I-port and accidentally connected

to another I-port. Use the identification labels (type IBS-6x10 or IBS-9x20) in order
to identify modules uniquely.

 Before starting the system, check whether the I-port assignment corresponds to the

configuration in the host system.
You can thereby avoid:
– Unintended movements of actors.

Warning

Accidental activation of actuators!
An incorrect status of the valves and outputs can lead to dangerous situations!
 Make sure that valves and outputs are put in a safe status when malfunctions occur.

Note

Please note the following if the outputs of a valve terminal are reset after master stop,
fieldbus interruption or malfunction:
– Monostable valves move to the initial position
– Double-solenoid valves remain in the current position
– Mid-position valves go into mid-position (pressurized, exhausted or closed, depend

ing on valve type).
 Observe the product specific instructions in the documentation supplied with the

valve terminal components.

4.6.4 Parameter “I-port configuration”

Through the parameter “I-port X configuration” (X = number of the I-port), the type of diagnostics or

First and foremost, the setting is used for monitoring whether a device is connected and, if so, whether
it fits the configuration presetting.

At system start, the parameter is set to “Use existing device”. This setting can only be
changed after the system start.

Nominal configuration

Devices recognised at system start are saved as the “nominal configuration”. This nominal configura
tion remains intact even after modification of the parameter “I-port configuration” and is sometimes
even used by other configurations.
The following I-port configurations are available:
– Use existing device (standard setting)

Operating mode “Automatic configuration”:
A device recognised at an I-port during system start is stored as a nominal configuration for this
I-port. When communication with the device is interrupted, the error “I-port device missing/failed”
is output. If the device is replaced by another device, this results in an “I-port configuration error”.
Additional information: è 5.7.1 Operating mode “Automatic configuration”.
Operating mode “Manual configuration”:
Communication with the device works in a manner corresponding to the set I/O configuration (the
device must correspond to this configuration). If communication is interrupted, an error is not out
put. If the device is replaced by another device, various sequences are possible
(è 5.7.2 “Manual configuration” operating mode).

– Expect device

This I-port configuration always requires a device connected to the corresponding I-port. An I-port
with this I-port configuration must always be connected to a device. Otherwise, an error is output.

5 Diagnostics and error handling

5.2 Diagnostics/error messages

Note

A requirement for transmission of diagnostic/error messages (if supported by the re
spective fieldbus) is an existing connection to the host system (è 3.6) and a corres
ponding parameterisation of the CTEL master module (è 4.6).
In the operating mode “Automatic configuration” without connected devices (0I/0O),
no diagnostic/error messages can be transmitted to the bus node. The diagnostic dis
play in this case takes place locally through the LEDs.

5.2.1 Priorities of the diagnostics/error messages

The CTEL master module differentiates between 5 different instances (system + 4 I-ports) that can
cause the diagnostics/error messages.
The instances have different priorities in the CPX system. If several diagnostics/error messages cannot
be displayed parallel to each other on the fieldbus side, the error message with the highest priority is
displayed.

Priority Error instance Description

Highest System Error in the CTEL master module
 I-port 1 Error in the module at I-port 1
 I-port 2 Error in the module at I-port 2
 I-port 3 Error in the module at I-port 3
Lowest I-port 4 Error in the module at I-port 4

Tab. 5.2 Priorities of the error instances

The error instances of the I-ports are assigned standard to the outputs. If no outputs are
intended in the configuration of the CTEL master module, the error instances are assigned
to the inputs.

In the CPX terminal, the individual modules also have prioritisation. This runs from the
CPX bus node (always completely to the left) descending to the right. Modules that are
closer to the bus node thus have a higher priority than modules that are further to the
right.

Within a CPX terminal, diagnostics/error messages with reference to inputs have priority
over diagnostics/error messages of outputs. This principle of error prioritisation also
finds use in the CTEL master module in the I/O mixed operation.

5 Diagnostics and error handling

5.7 Behaviour after lost connection to the device

With an interruption of the communication between the CTEL master module and a device (e.g. through
a wire break), the CTEL master module puts out various diagnostic/error messages. These are (also)
dependent on the selected operating mode and the setting of the parameter “I-port configuration”.

5.7.1 Operating mode “Automatic configuration”

When communication with the device is interrupted, the CTEL master module issues the error “I-port
device missing/failed” (CPX error number 57).

If input bytes are assigned for the separated module in the CPX system, these are auto
matically set to “0”.
For existing output bytes, their last known status is saved.

After an interruption is determined, the relevant I-port is queried cyclically and checked for a connec
tion-capable device.
If a device is recognised, the following procedures are then possible:

The exact same device (same serial number) is recognised that was connected to the CTEL master
module prior to the interruption.

In this case, the error in the module is reset and the system can be further operated immediately.

An identically constructed device (same number of I/Os, different serial number) is recognised.

In this case, the error in the module is also reset and the system can be further operated immediately.

Another device is recognised.

An “I-port configuration error” is reported on the diagnostics channel of the corresponding I-port.

The “I-port configuration error” is only displayed if the power supply of the CPX terminal
has not been interrupted. Otherwise, when the system is started, the connected device is
recognised as the setpoint configuration and no error is reported.

5.7.2 “Manual configuration” operating mode

During operation with manual configuration, the I-ports are checked only for the I/Os and I/O lengths
that are set and assigned in the CPX system.
If the configuration parameter of the corresponding I-port is set to “Use existing device”, no error is
issued.
If the configuration parameter of the corresponding I-port is set to “Expect device”, the CTEL master
module issues the error “I-port device missing/failed” (CPX error number 57) when communication
with the device is interrupted.

If input bytes are assigned for the separated module in the CPX system, these are auto
matically set to “0”.
For existing output bytes, their last known status is saved.

Festo – P.BE-CPX-CTEL-EN – 1411a – English 51

5 Diagnostics and error handling

After an interruption is determined, the relevant I-port is queried cyclically and checked for a connec
tion-capable device.
If a device is recognised, the following procedures are possible:

The recognised device agrees with the manual configuration (I/Os and I/O lengths).

The system can continue to be operated without limitation.

If the I/O length of the recognised device is less than the length established in manual
configuration, the I/O bytes used are assigned to the “lower end” of the reserved address
space in the CPX system.
The unassigned bytes at the “upper end” remain unused.

Example:
Manual configuration with an I/O length of 8 bytes. A device with an I/O length of 4 bytes is connected.
The 4 bytes of the device are assigned to the first 4 bytes in the address space of the I-port. The re
maining 4 bytes remain unused.

I-Port Fixed I/O length 8 bytes Device: 4 bytes

I-Port Byte 0 Byte 0

Byte 1 Byte 1
Byte 2 Byte 2
Byte 3 Byte 3
Byte 4 X
Byte 5 X
Byte 6 X
Byte 7 X

Tab. 5.5

The recognised device has established a larger I/O length than in the manual configuration.

The system can still be operated. But the I/O bytes that “project” beyond the reserved address space
are ignored.
Example:
Manual configuration with an I/O length of 4 bytes. Connected is a device with an I/O length of 8 bytes.
The first 4 bytes of the device are assigned to the 4 bytes in the address space of the I-port. The re
maining 4 bytes of the device remain unused.

I-Port Fixed I/O length 4 bytes Device: 8 bytes

I-Port Byte 0 Byte 0

5 Diagnostics and error handling

An output device is recognised, but the CTEL master module is configured for operation as a pure
input module.

The system can still be operated. Corresponding to the setting for the relevant I-port, either an I-port
configuration error is reported (with setting “Expect device”) or no error message is issued (with set
ting “Use existing device”).
The reserved input data address space is completely assigned; all input bits are set to the value “0”.
Write access to the outputs of the connected device is not possible.

An input device is recognised, but the CTEL master module is configured for operation as a pure out
put module.

The system can still be operated. Corresponding to the setting for the relevant I-port, either an I-port
configuration error is reported (with setting “Expect device”) or no error message is issued (with set
ting “Use existing device”).
The reserved output data address space is completely assigned. All write access to the output bits is
ignored.
Changes in status of the device inputs are also ignored.

5.8 Behaviour with error at the PL/PS supply

If the CTEL master module recognises a short circuit or overload at an I-port on one of the related
power supply cables PS or PL, the I-port involved is always switched off completely (PS and PL off ).
Behaviour after elimination of the error can be set via the parameter “Behaviour after I-port short cir
cuit” (è 4.6.3 Parameter “Behaviour after I-port short circuit”).
