1.1.2 I-port interface

I-port is a Festo-specific interface for transmitting communic­ation data (process data, sensor signals, pilot signals) and
supply voltages.

The I-port communication protocol is based on the IO link
protocol. The electrical and mechanical link between bus
nodes and I-port device is standardised.

The bus node has separate operating and load voltage sup­plies. It also supplies voltage to the devices connected via the
I-port interface.

Located at the bottom of the bus node is the I-port interface
for connection to an I-port-compatible device, e.g. valve ter­minal or decentralised electrical connectio n box.

– Predefined master/slave connection set for the simplified

transmission of I/O data between the master and the PLC
and the slave and the bus node

– Real-time operation: Exchange of I/O data in “real-time”

– Message types supported for the Master/slave I/O con-

nection:

– Polled communication (“I/O polling”)

– Change of state / Cyclic communication

– Supports the QuickConnect feature and the Automatic

1. Introduction

1.2 General information on the fieldbus protocol DeviceNet

1.2.1 Central component of the fieldbus protocol

Participant features

A DeviceNet participant is configured based on product-spe­cific data and characteristics, which the manufacturer
provides in the form of electronic datasheets (EDS). These
EDS files contain the product code, revision data and the
available address space (input/output size).

The configuration program of the DeviceNet Master manages
the EDS files of all fieldbus participants in a list or an EDS
library.

Special Device Configuration Files contain additional project
data over and above the content and scope of the EDS file.

Communication protocol

According to the layer model of the International Organisation
for Standardisation (Open Systems Interconnection Reference
Model - OSI), DeviceNet uses the principles of the Controller
Area Network (CAN) Protocol at security layer level (Data Link
Layer),aswellastheCommonIndustrialProtocol(CIP)forthe
upper communication level.

The DeviceNet protocol therefore represents a conversion
from CIP based on CAN principles.

1. Introduction

Message types

The following message types are available for master/slave
networks (predefined master/slave connection set):

– Polled communication (“I/O polling”)

or

– Change of state / Cyclic communication

Object directories

DeviceNet devices have an object directory which makes all
important participant parameters accessible in a standard­ized manner. A DeviceNet system is essentially configured by
accessing the objects in the object directory of the individual
fieldbus participants.

2.1 Installation

This chapter contains information for mounting the Bus node
CTEU on an I-port-compatible device (e.g. valve terminal with
I-port interface) and for installing this combination in a high­er-level field bus system (network).

2.1.1 Safety regulations

Warning

Danger of injury through uncontrolled movements of con­nected equipment.

Make sure that electrical and pneumatic equipment are in
a de-energised and pressureless status.

Before working on the pneumatics:

• Switch off the compressed air supply

• Vent the valve terminal

Before working on the electrical components, e.g. before
installation or maintenance work:

• Switch off power supply

In this way, you can avoid:
– uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the connec-

ted actuators

– undefined switching states of the electronics

Festo P.BE-CTE U-DN-OP+MAINT-EN en 1206NH

2-3

2. Install ati on and interfaces

Note

The bus node includes electrostatically sensitive devices.

• Do not touch any electrical or electronic components.

• Observe the handling specifications for electrostatically

sensitive devices.

They will help you avoid damage to the electronics.

Note

Use protective caps to seal unused connections. This is
how you achieve protection class IP65/IP67.

2.1.2 Mounting the bus node

A valve terminal with I-port interface or an electrical connec­tion box, type CAPC-..., is required to mount the bus node.

Note

Information on mounting the bus node on the electrical
connection box type CAPC-... canbefoundintheassembly
instructions that accompany the connection box.
For H-rail mounting, you also need the mounting kit
CAFM-... (CAPC and CAFM).

2.2.2 Power supply

The bus node has separate operating and load voltage
supplies. The bus node also supplies voltage to equipment
connected via the I-port interface.

Note

• Use only PELV circuits for the electrical power supply in

accordance with IEC/EN 60204-1

(Protective Extra-Low Vo l tage, PELV).

• Observe the general requirements in accordance with

IEC/EN 60204-1 for PELV circuits.

• Useonlyvoltagesourcesthatguaranteeareliableelec-

tric separation of operating and load voltage in accord­ance with IEC/EN 60204-1.

• Always connect both circuits for operating and load

voltage supply.

Through the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is en­sured in accordance with IEC/EN 60204-1.

Note

Fieldbus participants of different manufacturers have dif­ferent tolerances regarding the power supply to the bus
(V+, also designated as CAN_V+ or CAN+).

– Tolerance range of the power supply to the bus of the

fieldbus interface CTEUDN: DC 11 … 30 V, reverse polar­ity protected

Fieldbus connecting cable – Specification and configuration

For fieldbus communication, Festo recommends the use of a
two-pair, screened fieldbus connecting cable (network cable).

• You need at least a screened 4-wire line

(CAN_H/CAN_L as well as V +/V –).

• Preferably use cable with twisted and screened wire

pairs.

• Always use a terminating resistor (121Ω ±1%, 0.25W)

at both ends of the fieldbus between the wires for
CAN_H and CAN_L.

• Connect the screening of the fieldbus cable to the

fieldbus plug.

• Connect the screening continuously to all fieldbus

cables and earth the screening only once (star­shaped) to avoid ground loops.

• Make sure that the connected fieldbus equipment or

the decentrali sed adapter is earthed.

• Observe the specifications in the manuals of your con-

trol system, in particular regarding the bus lines,
cable type, max. length of branch lines and branches
as well as the connection technology (network plug,
adapter).

• In calculating the max. effective data rate, also take

into account the length of branch lines and branches

 Section 2.2.6, “Setting the DIL switches”
 Information on maximum usable data rate (baud

rate).

2. Installation and interfaces

Note

Faulty installation and high transmission rates may cause
data transmissio n errors as a result of signal reflectio ns
and attenuations.

Fieldbus adapter (bus connection/plug-adapter) for
continued fieldbus communication

With fieldbus adapters from Festo ( Tab. 2/4 below), you
can separate the fieldbus connection from the bus node
without interrupting the communication of the remaining
fieldbus participants.

You can use the following fieldbus adapters for forwarding
the fieldbus connection.

account the length of the network lines (main bus line,
branch lines and branches)  seenotebelow.

Note
Maximum effective data rate (baud rate)

The setting of the baud rate depends on the length of all
fieldbus connecting cables (network lines).

• Consider the length of the fieldbus line between the PLC

and bus node (main bus line) as well as the length of any
existing branch lines and branches for continued field­bus configuration.

• Also consider the overall length (sum) of all branch lines.

• The table below contains reference values for the max-

imum baud rate, depending on the line lengths. The
baud rates named here are not supported by all control­lers.

• Observe any deviating specifications in the manual of

Warning

• Prior to switch on: make sure that the requirements for

commissioning have been met. Also observe Sec­tion 3.1.2, especially regarding the DIL switch setting.

• During operation: do not alter the DIL switch setting

during operation. This will prevent accidental and un­controlled movements of the connected actuators and
undefined switching states of the electronics.

3.2.3 DeviceNet participant features (EDS file)

To configure the CTEU-DN bus node, an Electronic Data Sheet
(EDS) containing all product-specific data and characteristics
of the bus node accessible via the network is available: The
EDS is therefore also referred to as the device description file.

The characteristics and functions described in the EDS file are
summarised under the term DeviceNet participant character­istics.

DeviceNet participant characteristics can also be configured
manually, without installing an EDS file (“enter”).

All characteristics of the DeviceNet participants are usually
contained in an EDS library in the controller software.

EDS variants The individual network participants are configured via a

standard EDS or a modular EDS:

– A standard EDS contains all the required information

across the entire installation system e.g. the bus node
and corresponding valve terminal.

– A modular EDS provides a separate EDS file for every sys-

tem component, every module (bus node, I/O module,
valve terminal etc.) as well as individual functions.

EDS for CTEU- DN To configure the CTEU-DN bus node or the CTEU installation

system, a standard EDS file is available  Section 3.2.4.

(e.g. by installation of the EDS file), the following steps are
required for starting up the bus node:

1. Insert the CTEU-DN bus node (“par ticipant”) into the pro­ject/network (online or offline).

If the participant is inserted offline, for example, it will be
selected from the participant list and added to the net­work.

2. Assign the participant to a scanner.

– A network may contain several scanners.

– The participant must be uniquely assigned to a scan-

ner.

3. Define the I/O parameters of the participant.

The following details are required here:

• Number of the I/O bytes to be transmitted

For the CTEU-DN bus node or the CTEU installation
system, the number depends on the connected I-port
devices.

• Message type

For the CTEU-DN bus ode:

– Polled communication (“I/O polling”)
or
– Change of state / Cyclic communication

4. Commissioning

Note

The following applies when using a Allen-Bradley SLC 500
PLC in conjunction with an Allen-Bradley scanner type
1747-SDN:

– “Change of state / Cyclic communication” can only be

used in conjunction with the diagnostics via Strobed I/O
starting from software version V4.015 of the scanner.

• Assign the I/O addresses of the participant to the PLC

operands.

• Diagnosticbytes(forI-port1andI-port2)tothePLC

operands, insofar as diagnostic mode has been activ­ated via the DIL switch.

Note

The specification of diagnostic mode (assignment of dia­gnostic bytes) must correspond to the DIL switch setting
 Section 2.2.6.

4. Load the configuration into the scanner.

4.3 Parameterisation

Note

Observe the subsequent sections to ensure that the para­meterisation required for your application is automatically
restored at switch-on, after a restart or after a devi ce re­placement.

Check which settings are required, especially before a
device replacement. Make sure that these settings are
retained or restored (e.g. by the higher-order
controller/PLC)  Section 2.3.

4.3.1 Methods of p arameterisation

CTEU-DN can be parameterised as follows ( Tab. 4/15):

– via the configuration program

– via the scanner

–viatheuserprogram

Use the QuickConnect and Automatic Device Replacement
(ADR) DeviceNet functions or communi cation and program­ming via Explicit Messaging, in order to set the required para­meters.

In this case, the PLC automatically transmits the programmed
parameters to the bus node after switch-on. The settings will
then be retained even after a restart or device replacement.

Note

The last parameterisation received in the CTEU-DN is al­ways valid.

4. Commissioning

4.3.3 Device-specific parametrisation

The CTEU-DN bus node has device-specific parameters, re­ferred to as parameter objects, e.g. for setting the behaviour
of the connected I-port devices or for activ ating certain status
signals. These parameters can be set in the configuration
program (“network configurator”  “Parameters”).

Thetypeandscopeoftheparameterobjectsavailablein
CTEU-DN depends on the connected I-port device.

Use the QuickConnect and Automatic Device Replacement
(ADR) DeviceNet functions or communi cation and program­ming via Explicit Messaging, in order to set the required para­meters ( Section 4.3.1 and Tab. 4/15).

In this case, the controller (PLC) automatically transmits the
programmed parameters to the bus node after switch-on. The
settings will then be retained even after a restart or device
replacement.

To use explicit messaging programming, you need the object
descriptions and addresses of the DeviceNet object model
 Appendix A.4.

4.3.4 Behaviour of the inputs and outputs in fail state mode

In case of a control or communication interference, the net­work participants, i.e. the bus nodes and the I-port devices,
assume fail state mode.

Possible causes of fail state mode:

– Interference in the control system (PLC/scanner)

– Network/fieldbus interruption (e.g. communication inter-

ference, broken cable)

Festo P.BE-CTE U-DN-OP+MAINT-EN en 1206NH

– Interference to data telegrams.

4-15

4. Commissioning

Depending on the DIL switch setting, the inputs and outputs
hold the last state or reset to the basic state  Tab. 2/7.

The selected setting applies for all outputs. (Factory setting:
“reset”).

4.3.5 Behaviour of the inputs and outputs in idle state mode

Idle mode is assumed by the network participants when this
is requested by the controller or scanner. The controller is
then in stop mode.

Depending on the DIL switch setting, the outputs hold the last
state or reset to the basic state  Tab. 2/7.

The inputs of the network participants continue to be trans­ferred to idle state mode.

The selected setting applies for all inputs and outputs and is
coupled to the setting for the fail state mode. (Factory setting:
“reset”).

4.3.6 Parameterisation via a user program (explicit messaging)

Parameter values can also be read and written by the control­ler. To do so, communicate and program via “Explicit Mes­sage”. The required parameter values are specified in a user
program.

For this parameterisation method, you require device-specifi c
parameter objects and/or the corresponding object descrip­tions  Tab. 4/16 and Tab . 4/17. Note that these tables spe­cify only the frames for using parameterisation via explicit
messaging.

5.3 Reaction to malfunctions in the control system

The reaction of outputs and valves to control and communica­tion malfunctions can be set via device-specific parameterisa­tion  Section 4.3.4.

In case of a malfunction, the network participants, i.e. the bus
nodes and the I-port devices, assume the parameterised fail
state mode.

Depending on the DIL switch setting, the inputs and outputs
hold the last state or reset to the basic state  Tab. 2/7.

The selected setting applies for all outputs. (Factory setting:
“reset”).

Note

Pleasenotethefollowingvalvereactioniftheoutputsare
reset after PLC stop, network/fieldbus interruption or other
malfunction:

– Monostable valves mo ve to the basic position
– Double-solenoid valves remain in the current position
– Mid-position valves move to mid-position (pressurized,

exhausted or closed, depending on valve type).

Warning

Danger of injury.

• Make sure that outputs and valves are moved to a safe

state when malfunctions occur .

Incorrect output and valve states can cause dangerous
situations!

d

Short circuit or overload monito ring depends on the connec­ted I-port device: When the I-port device monitors the load
voltage and I-port connection for short circuit and overload,
corresponding error messages are generated and forwarded
to the PLC. On the bus node, the “PS” LED flashes green,
showing a malfunction in the operating and load voltage sup­ply ( Tab. 5/2).

6.1 Fault finding and error elimination

This section is meant as a checklist to help you inspect your
installation and commissioning steps if an error occurs. You
will find information on fault finding and error elimination, as
well as references to the respective chapters of the two-part
product documentation on the bus node.

Eliminate individual sources of error by running the following
checks in the specified order.

6.1.1 Check installation

• Check the mechanical and electrical installation of the bus

node on the I-port device or the electrical connection box
and the correct earthing of all of the components in­volved.

• Check whether all the required connection lines and con-

necting cables are fitted correctly .

• Carefully check potential l y faulty lines and cables.

• Replace any visibly damaged lines and cables.

Information relating to installing the bus node can be found in
Part I of the product documentation entitled “Installation and
Interface manual”, which is supplied with the bus node.In­formation for mounting the bus node on the electrical connec­tion box CAPC-... can be found in the assembly instructions
supplied with the electrical connection box.

6.1.2 Check the power supply

Warning

• Use only PELV circuits for the electrical power supply in

accordance with IEC/EN 60204-1
(Protective Extra-Low Vo l tage, PELV).

• Observe also the general requirements for PELV circuits

in accordance with IEC/EN 60204-1.

• Useonlyvoltagesourcesthatensureareliableelectric

separation of operating voltage in accordance with
IEC/EN 60204-1.

• Always connect both circuits for operating and load

voltage supply.

• Check to make sure both power supplies for the operat-

ing and load voltage are connected.

Note

The devices connected to the bus node are powered ex­clusively via the load voltage connection.

• Check the pin assignment of self-assembled cables.

Information relating to installing the bus node can be found in
Part I of the product documentation entitled “Installation and
Interface manual”, which is supplied with the bus node.

Normal status LED PS-LED illuminates green and the X1-L ED and/or X2-LED illu-

minate green.

Error status 1 The operating voltage supply for the bus node exhibits under-

voltage:

6-4

– PS-LED flashes green

Festo P.BE-CTEU-DN-OP+MAINT-E N en 1206NH

6. Error handling

Error status 2 The load voltage supply for the connected device is missing

or exhibits undervoltage:

– PS-LED flashes green

and

– X1 and/or X2-LED flash green

Note

Requirement for diagnostics via LED display:
The connected device must support this diagnostic function.
(Additional information can be found in the respective device
description).

6.1.3 Restart communication between the bus node and the device

Problem description: X1 and X2 flash red simultaneously.The check of the mechani cal

connection between bus node and device (dismantling/in­stalling) effected no change. The fault cannot be eliminated in
this way.

Remedy Proceed as follows:

1. Disconnect the operating vol tage.

2. Check, sever and re-establish the electrical connection
between the bus node and connected devices.

3. Restore voltage.

X1 and/or X2 illuminate or flash green.

6.1.4 Check fieldbus communication

• Compare the desired baud rate with the baud rate set on

the bus node (DIL switch setting).

Festo P.BE-CTE U-DN-OP+MAINT-EN en 1206NH

• Compare the desired station number (NodeID) with the

station number set on the bus node (DIL switch setting).

6-5

6. Error handling

Information relating to installing the bus node can be found in
Part I of the product documentation entitled “Installation and
Interface manual”, which is supplied with the bus node.

• Compare your cable lengths with the technical data in the

Attachment and the recommendation in the CiA specifica­tion ( Tab. 2/8).

• Test the fieldbus communication using the object direct-

ory ( Appendix A.4).

Normal status LED MNS-L ED is off and I/O-LED illuminates green (in operational

mode).

MNS-LED is off and I/O-LED is off (if no fieldbus communica­tion).

6.1.5 Check DeviceNet configuration

Problem description: Process data are defective.

Remedy Proceed as follows:

1. Check whether the I/O mapping matches the controller
settings ( Appendix A.4).

2. Check whether the bus node status, e.g. operational
mode, matches the controller settings ( Section 5.2.5).

Problem description: Outputs do not switch to the desired state if fieldbus commu-

nication is disrupted.

Remedy Proceed as follows:

1. Check whether fail state mode or idle state mode is activ­ated in the controller.

6-6

This ensures that the bus node can detect disrupted field­bus communication and that the outputs are set to a
defined state after fieldbus communication is restored
(network communication).

Festo P.BE-CTEU-DN-OP+MAINT-E N en 1206NH

6. Error handling

2. Check whether Fail State is activated on the bus node (DIL
switch position).

Fail state mode off (reset):
The outputs are reset to “0” after fieldbus communication
is restored.

Fail state mode on (hold last state):
Once fieldbus communication is restored, the outputs
resume their state prior to failure.

6.1.6 Read out diagnostic messages via DeviceNet

Problem description: Th e previous checks are “fruitless”, i.e. provide no informa-

tion about the cause of the fault.

Remedy: Read out diagnostic messages via DeviceNet.

Requirement: The I-port devices connected to the bus nodes can offer

advanced diagnostic options.

Additional prerequisites:

– Diagnostic mode is activated:

Check the DIL switch setting.

– Network connection to the connected I-port device is

available:
X1 or X2-LED flashes green.

Proceed as follows:

Evaluate the diagnostic information in the process data (see
Section 5.3).
