• Check the start behaviour of the CPX terminal before

replacing the bus node.

If the Modify LED (M) illuminates or flashes permanently
after the system start, “System start wi th saved paramet­risation and saved CPX expansion” is set or “Force” is act­ive. In this case parameterisation is not created automatic­ally by the higher-order system when replacing the bus
node or CPX terminal during servicing.

• Therefore, verify which settings are required before re-

placement and restore these settings after replacement.

• Always use the correct screws for the interlinking block,

which depend on whether the block is made of metal or
plastic:

–forplastic interlinking blocks:

self-tapping screws

–formetal interlinking blocks:

screws with metric thread.

Both types of screws are enclosed respectively when ordering
the bus node as a single part.

Mounting the bus node 1. Check the seal and the sealing surfaces between the bus

node and interlinking block.

2. Place the bus node in the interlinking block without
tilting. Make sure that the corresponding slots with the
contacting terminals on the bottom of the bus node are
above the contact rails.

3. Push the bus node carefully and without tilting as far as
possible into the interlinking block.

4. Set the screws so that the self-cutting threads can be
used.

1.2.1 Setting the operating mode and protocol

• Use DIL switch group 1 ( Fig. 1/1 1).

Operating mode and protocol

Remote I/O operating mode

All functions of the CPX terminal are controlled
directly via EtherNet/IP or Modbus TCP.
A CPX-FEC or CPX-CECthat may be integrated
into the CPX terminal works as a passive function
module without controller.

Operating mode Remote Controller

A CPX-FEC or CPX-CECintegrated into the CPX
terminal takes over I/O control.

EtherNet/IP protocol

The CPX terminal uses the EtherNet/IP protocol.

Modbus TCP protocol

The CPX terminal uses the Modbus/TCP
protocol.

1.3.1 General information about networks

Note

Sub-assemblies with Ethernet interfaces should only be
operated in networks if all connected network components
are supplied by PELV power supplies or integrated power
supplies with equivalent protection.

Installation guidelines

The installation guidelines can be obtained via the OD VA user
organisation:

 Internet: http://www.odva.org

Observe the instructions in these documents.

Use of switches and routers

The switch integrated in the bus node permits division of the
network into several segments.

With use of additional switches and routers, the network can
be divided into additional segments. Thus, it is possible to
structure the network and realise greater network expan­sions.

Independent of the network structure, the expansion of a
network segment must not exceed certain connection
lengths.

2.1 EtherNet/IP protocol

EtherNet/IP is an industrial Ethernet protocol, which is pre­dominantly used in automation technology.

The EtherNet/IP protocol is activated with DIL
switch 1.2 = OFF. The bus node is then identified with the
designation: FB36 - EtherNet IP Remote-IO

After switching the protocol ( section 1.2.1) the following
unmodified parameters are available:

– IP address

–Diagnosticsmode

– System parameters

The DIL switch function remains unchanged.

Retentive bus-specific parameters are onl y active if the relev­ant protocol is selected ( section 1.2.1).

Parameterisation examples can be found in appendix C.5.

2.1.1 Multicast telegram

EtherNet/IPusesIPMulticasttelegramsasstandardfor
transferring process data. An advantage of Multicast com­pared to Unicast is that a telegram can be received by mul­tiple participants.

Simple switches, however, cannot distinguish to which parti­cipant a Multicast telegram is to be transferred. Therefore,
these switches send the Multicast telegrams to all devices in
the network.

This results in an EtherNet/IP participant receiving numerous
unnecessary telegrams, which must then be discarded from
the device. This can reduce the response times of the parti­cipants. The demand on the network bandwidth increases.

Festo P.BE-CPX-F B36-EN en 1309NH English

2. Preparing for commissioning

This does not pose a problem for smaller networks; the per­formance for larger networks, however, can be improved with
the following functions and/or protocols.

– Use of switches wi th “IGMP snooping”

– Segmentation of the network

Switches with “IGMP snooping”

By using an IGMP (Internet Group Management Protocol) the
switches are able to decide to which devices the various Mul­ticast telegrams are transferred. This allows unnecessary
Multicast traffic to be avoided.

• Activate this function in all switches/routers used.

• Configure at least one switch so that cyclical IGMP quer-

ies are sent. The IGMP snooping function cannot work
properly without these IGMP queries.

2.1.2 QuickConnect

2-4

Segmentation of the network

• Split the machine into smaller network segments. This can

be realised without changing the network cabling, for
example, by using VLANs.

The EtherNet/IP function QuickConnect (QC) enables a quick­er initialisation of the CPX terminal and a fast connection set­up to the EtherNet/IP master.

QuickConnect is commonly used for applications with a tool
change, for which the downtime should be minimised by the
disconnection and connection of devices.

The bus node corresponds to a Class A device of the Ether­Net/IP specification. When switched on, the bus node re­quires less than 350 ms to accept a TCP connection.

Note

Due to the rapid establishment of the TCP connection, the
detection of already used IP addresses (IP Address Con­flict Detection, ACD) is not executed completely. This can
lead to multiple assigned IP addresses only being detected
at a late stage. This can impair the function of the network.

Fig. 2/2: Device Level Ring topology, example

The availability of the network can be increased by using ring
topology as there are redundant communication paths
between two devices. A cable or communication fault
between two devices will therefore not result in communica­tion failure. Only two faults in a ring will lead to a malfunction.

A ring always consists of at least one ring supervisor and any
number of ring nodes.

• Only use DLR-compatible devices in a ring.

Otherwise, the time required for automatic elimination of
a fault may be adversely affected.

• Operate the bus node as a ring node either in a beacon-

based or announce-based configuration.
Operation as a ring supervisor is not possible. This func­tion is normally executed by an EtherNet/IP scanner.

The DLR protocol is configured via the DLR object (class

2.2 Modbus/TCP protocol

Modbus is an open communication protocol based on the
master-slave architecture. This is a standard for communica­tion via TCP/IP in automation technology.

The Modbus/TCP protocol is activated with DIL
switch 1.2 = ON. The bus node is then identified with the des­ignation: FB36-MB - Modbus TCP Remote-IO

After switching the protocol ( section 1.2.1) the following
unmodified parameters are available:

– IP address

–Diagnosticsmode

– System parameters

The DIL switch function remains unchanged.

2-10

Retentive bus-specific parameters are onl y active if the relev­ant protocol is selected ( section 1.2.1).

The configuration options via Modbus TCP correspond to
those via EtherNet/IP.
Exception: EtherNet/IP objects cannot be accessed via Mod­bus TCP.

In order to configure the CPX terminal for Modbus/TCP, you
will require the Modbus addresses of the data and of the I/Os
of the CPX terminal ( appendix D).

Addressing examples can be found in appendix D.6.1.

the documentation or online help for the controller or control
program.

Note

Bus node CPX-FB36 can be used on all EtherNet/IP or
Modbus/TCP controllers.

The following section describes the configuration and
commissioning procedure using the example of
Rockwell/Allen-Bradley controllers (PLC) via the Rockwell
RSLogix software platform.

2.3.1 Requirements for commissioning

– Installation of the bus node is complete ( chapter 1)

3.1.4 Configuration in the Remote Controller operating mode

When using a CPX-FEC or CPX-CEC in your CPX terminal, the
CPX-FB36 is to be used as the Remote Controller.

In principle, the bus node is configured in the same manner
as in the Remote I/O operating mode, but with different I/O
data lengths.

The bus node then occupies 8 or 16 input bytes and 8 or 16
output bytes (dependent on the switch position DIL 2.2
 Tab. 1/2).
These inputs and outputs are available to the control pro­gram of the CPX-FEC or CPX-CEC.

To use the Remote Controller operating mode:

1. Use DIL switch group 1 to set the bus node to the Remote
Controller operating mode and select an EtherNet/IP or
Modbus TCP protocol ( chapter 1.2.1).

2. Use DIL switch group 2 to set the required data field size

Warning

Uncontrolled movements of the actuators, undefined

Injury to people, damage to the machine and system

• During the parameterisation process make sure that

nobody is within the sphere of influence of moving parts
of your system.

Parameterisation of the CPX-FB36 influences the behaviour
of the CPX terminal.

The CPX terminal is supplied from the factory with preset
parameters. These parameters are saved in the bus node.

These parameters can be used to largely adapt the behaviour
of the CPX terminal to the relevant application.

A distinction is made between the following variants:

– System parameters, e.g. setting reaction times, switching

– Module parameters (module- and channel-specific), e. g.

– Parameters of the diagnostic memory

A detailed description of the individual parameters as well as
basic principles of application can be found in the CPX system
description ( P.BE-CPX-SYS-...).

The module parameters can be found in the descriptions for
the modules, e.g. description of the CPX pneumatic interfaces
and CPX I/O modules ( P.BE-CPX-EA-...).

3.2.1 Parameterisation when switching on (system start)

Parameterisation of the CPX terminal is initially dependent on
the setting of the “System start” parameter. This parameter
establishes whether the default parameters or the paramet­ers saved by the user in the bus node are used wh en switch­ing on the CPX terminal.

The parameterisation is loaded again after every interruption
of the power supply or the network connection. An exchange
of individual CPX modules is therefore possible, for example,
without the need for re-parameterisation.

Sequence of parameterisation when switching on
the CPX terminal

System start with default parameters

1. The controller transmits the parameterisation that is
saved in the controller to the bus node.

3-22

2. The bus node distributes this parameterisation to the
individual modules.

System start with saved parameters

1. The bus node distributes the parameterisation that is
saved in the bus node to the individual modules.

The parameterisation saved in the bus node can be overwrit­ten accidentally by the controller.

• Please observe the general commissioning instructions in

the CPX system description.

• Check the DIL switch settings and the network configura-

tion before using and replacing CPX terminals.

• Check the configured address range. If necessary, test the

I/Os.

• ChecktheaddressassignmentoftheI/OsontheCPX

terminal. For this purpose you can, if necessary, force the
I/Os ( CPX system description).

• Make sure that the desired parameterisation of the CPX

terminal in the start-up phase or after network interrup­tions is restored by the interface module.
This ensures that if the CPX terminal is replaced, the new
terminal will also be operated with the desired parameter
settings.

3-30

• Use spot checks if necessary to check the parameterisa-

tion, either with a configuration program (e.g. RSLogix) or
with an operator unit (e.g.B. CPX-MMI).

4.3 Diagnostics via status bits

Status bits are internal inputs (1 input byte), which serve to
display common diagnostic messages (global error mes­sages).

Note

If status bits are to be transmitted via a “Polled” or
“Change of state” connection, you must set the DIL
switches on the bus node accordingly ( Tab. 1/2).

If all status bits supply logic 0, no error will be reported. The
following table shows the diagnostic information when there
is a 1-signal:
