Chapter 1
1. About the Anybus Communicator CAN
1.1 Introduction
The Anybus Communicator CAN is a series of products that acts as a gateway between a subnetwork,
running the standard CAN protocol, and a number of popular industrial networks. Integration of industrial devices is enabled without loss of functionality, control and reliability, both when retro-fitting to
existing equipment as well as when setting up new installations.
The Anybus Communicator CAN is based on patented Anybus technology, a proven industrial communication solution used all over the world by leading manufacturers of industrial automation products.
Each module offers integration of industrial CAN devices to one of these industrial networks: EtherCAT, PROFIBUS, ControlNet, Modbus-RTU, Modbus-TCP, PROFINET, PROFINET IRT, EtherNet/IP, DeviceNet, CC-Link and CANopen. The scope of this manual is the Anybus Communicator
CAN for CC-Link. The manual primarily describes the functionality and the configuration of the CAN
network and the connection between the CAN network and the CC-Link network. Relevant information on the CC-Link interface of the module is given, with the intention to facilitate the configuration
of the interface into a CC-Link network. For more information about CC-Link, please refer to official
specifications.
No proprietary configuration software is needed. All necessary configuration is performed using the tool
Anybus Configuration Manager that accompanies the product.

1.2 Anybus Communicator CAN Concept
1.2.1 General
The Anybus Communicator is designed to exchange data between a subnetwork, running CAN, and a
higher level network. The CAN protocol uses frames, that are individually configurable, offering great
flexibility.
Through the configuration of the CAN frames, the Communicator will adapt to a predefined CAN network. It will be possible to send data to and receive data from the subnetwork, but also to act as a relay
for data on the CAN subnetwork.
The Communicator can issue frames cyclically, on change of data, or based on trigger events issued by
the control system of the higher level network (i.e. the fieldbus master or PLC) or by the CAN network.
It can also monitor certain aspects of the subnetwork communication and notify the higher level network when data has changed.
An essential part of the Anybus Communicator package is the Anybus Configuration Manager, a Windows™ application which is used to supply the Communicator with a description of the subnetwork
protocol. No programming skills are required; instead, a visual protocol description-system is used to
specify the different parts of the CAN frames.

About the Anybus Communicator CAN 6
1.2.2 Data Exchange Model
Internally, the data exchanged on the subnetwork, and
the data exchanged on the higher level network, resides
in the same memory.
Anybus Communicator CAN
Internal Memory
This means that in order to exchange data with the subnetwork, the higher level network simply reads and
writes data to memory locations specified using the Anybus Configuration Manager. The very same memory
locations can then be exchanged on the subnetwork.
Input Data (Up to 48 bytes in v1 and up to
368 bytes in v2)
This area can be read by the higher level network.
Higher Level Network
•
Output Data
(v1: 48 bytes
v2: 368 bytes)
CAN Network
The internal memory buffer is divided into three areas
based on their function:
Input Data
(v1: 48 bytes
v2: 368 bytes)
General Data
•
Output Data (Up to 48 bytes in v1 and up to
368 bytes in v2)
This area can be written to by the higher level
network.
•
General Data
This area can not be accessed from the higher level network, but may be used for transfers between individual nodes on the subnetwork, or as a general “scratch pad” for data. The size of the
General Data area is 1024 bytes. How much data of the area that is used for subnetwork communication is decided by the configuration.
Memory Map
When building the subnetwork configuration using the Anybus Configuration Manager, the different areas described above are mapped to the memory locations (addresses) specified below.

4. CAN Network Communication
4.1 General
The CAN protocol is message-based and offers the possibility to exchange up to 8 bytes of data in each
message. How these bytes are interpreted, is defined in each application. The CAN protocol is a transparent protocol, meaning that it only acts as a data carrier, and it is up to the users (the application) to
define and interpret the data content of the messages.
Data on CAN is exchanged using frames. Each frame has a unique identifier for the data it exchanges.
The identifier also represents the message priority on the CAN network. The Anybus Communicator
CAN supports either 11-bit (CAN 2.0A) or 29-bit (CAN 2.0B) identifiers, depending on what is defined
during configuration.
CAN is essentially a produce-consume network, where all nodes listen to all messages. The devices recognize what data to collect by what identifier the CAN frame carries. The Communicator is also able to
act as a Master and issue queries that demand responses. It is possible to use both methods in the same
configuration of the module.
4.2 Types of Messages
The Anybus Communicator CAN features three different message types regarding the subnetwork communication, called ‘Query/Response’, ‘Produce’ and ‘Consume’. Note that these messages only specify
the basic communication model, not the actual CAN protocol. All three types of messages can be used
in the same configuration.
4.2.1 Query-Response
The Communicator acts as a master on the subnetwork, and the CAN communication takes place in a
query-response fashion. The Communicator sends a query and expects an answer within the specified
timeout.

CAN Network Communication 15
4.2.2 Produce and Consume
When using these messages, there is no master-slave relationship between the Communicator and the
nodes on the subnetwork. Any node, including the Communicator, may spontaneously produce a message. The message is sent on the network. The nodes on the network listen to all traffic and decide independently which messages to consume (read). Nodes do not have to respond to messages, nor do they
have to wait for a query to send a message on the network.
Control System
Communicator
Subnetwork Devices
Node 2
Node 1
Node 3
In the figure above, the Communicator ‘consumes’ data that is ‘produced’ by a node on the subnetwork.
This ‘consumed’ data can then be accessed from the higher level network. This also works the other way
around; the data received from the higher level network is used to ‘produce’ a message on the subnetwork to be ‘consumed’ by a node.
Note: When configuring the Communicator using the Anybus Configuration Manager, ‘produce’ and
‘consume’ are defined from the Communicator’s perspective.
4.3 Protocol Building Blocks
The following building blocks are used in Anybus Configuration Manager to describe the subnetwork
communication. How these blocks apply to the two modes of operation will be described later in this
document.
•
Group
A group in the Anybus Configuration Manager does not represent any special device on the CAN
network. It is a means to structure the transactions that are defined for the Communicator. Each
group can be associated with a number of transactions, see below.
•
Transaction
A transaction consists of one or more CAN frames. Each transaction is associated with a set of
parameters controlling how and when to use it on the subnetwork. There are five kinds of transactions: produce, consume, query-response, dynamic produce and dynamic consume. A group
can contain transactions of all three types simultaneously. A total of 128 transactions can be configured.
•
Dynamic Transaction
In normal transactions, all parameters are changed using the Anybus Configuration Manager. A
dynamic transaction makes it possible for a network master to change selected parameters during
runtime. The parameters are mapped to the output data area or to the general data area and it
will not be possible to change them using the Anybus Configuration Manager. A dynamic trans-

CAN Network Communication 16
action may only consist of one CAN frame that can hold up to one data object. Also only one
produce and one consume dynamic transaction are allowed.
•
CAN Frames
The CAN frames are low level entities used to compose transactions (see above). Each frame
carries an 11-bit or 29-bit identifier and can hold up to 8 bytes of data. See “Configuration of
CAN Frames” on page 36. A total of 256 CAN frames can be configured.

4.4 Control/Status Word
An optional control/status word can be used to control the startup mode of the module and to read the
status of the CAN network. The control word is always mapped to the first two bytes of the output data
area, and the status word is mapped to the first two bytes of the input data area. It is not possible to
change these locations.

Note 1: The picture shows the maximum available data areas in the Communicator. Not all fieldbuses
can access all addresses in the input and output data areas, please see section Data Exchange Model in
chapter 1.
Note 2: The control/status words are stored in the first two bytes of the data areas, with the least significant byte (bit 0-7) in the first byte (byte #0).
Through the control word it is possible to reset the CAN controller, reboot the module and decide the
start-up mode of the Communicator:

4.5 Transaction Live List
An optional transaction live list is available. It consists of a bit array where each bit corresponds to a
transaction on the CAN subnetwork. (bit 0 corresponds to transaction 1 etc.). A set bit indicates normal
functionality. The bit is not set if the transaction is non-working or non-existent. The live list is mapped
in the input data area of the memory, either at the start of the area or directly after the status word. From
8 transactions up to 128 transactions in steps of 8 can be monitored using the live list. Thus, up to 16
bytes of the input data area of the memory can be occupied by the live list.
The latest live list is always available from the Anybus Configuration Managers Diagnostics/Status window, whether the live list is mapped in the input data area or not, see “Diagnostics/Status” on page 44.

5. CC-Link Communication
5.1 General
The Anybus Communicator CAN acts as a CC-Link slave on the CC-Link network. As such, it does not
initiate communication towards other nodes by itself, but can be read from/written to by a CC-Link
master.
5.2 Data Representation
The Input and Output Data areas in the internal memory buffer are used for CC-Link data. The amount
of data exchanged on the bus depends on the configuration of the Communicator.
When setting up the CC-Link communication, make sure that the I/O sizes in the CC-Link master
match the actual sizes used by the Communicator. The data sizes can be viewed at any time, see “Address Overview” on page 43.
On CC-Link, data is organized as bit and word data, where a block of bit data is immediately followed
by a block of word data. By default, the Communicator exchanges data using version 1 of the CC-Link
protocol, and the data size depends on the number of occupied stations as follows:
Occupied Stations
1
2
3
4
Bit Data
4 bytes
8 bytes
12 bytes
16 bytes
Word data
8 bytes
16 bytes
24 bytes
32 bytes
The Communicator also supports CC-Link version 2 operation, increasing the amount of bit and word
data by utilizing an extended number of bus cycles (‘extension cycles’). In this case, it is possible to specify the number of occupied stations as well as the number of extension cycles, allowing a number of possible data sizes (below).
The bit and word data sizes correlate to the number of occupied stations and extension cycles as follows
(CC-Link Version 2):
Occupied

1
2
3
4

CC-Link Communication 20
5.2.1 CC-Link System Area
The Remote Ready flag in the CC-Link system area (input data, byte 0, bit 3) is used in order for the CCLink interface to appear as a CC-Link Remote Device. This functionality is available through the Anybus
Communicator Manager and is enabled by default to conform to the standard CC-Link profile. If the
functionality is disabled, the system area CC-Link communication flags can be handled freely but in accordance with any of the profiles defined in the CC-Link specification. How this is performed is beyond
the scope of this document.
IMPORTANT: The CC-Link interface is implemented according to the CC-Link Specification (publication BTP05028-B), which means that the last 16 bits of the bit data are reserved for the CC-Link System area, where various
CC-Link communication flags are found. The area cannot be used for data exchange if this functionality is enabled. This
behavior, that is different from that of most other networking systems, must be taken into account when setting up the
subnetwork configuration.
Note that most masters do not require the use of the CC-Link System Area-flags to operate, i.e. the gateway may be able to exchange data even if these flags are left untouched.

5.2.2 Memory Layout (Internal Memory Buffer)
The data in the input and output data areas is represented as continuous blocks of I/O data. Each data
object in a CAN frame adds to the total amount. Usage of the memory can always be seen in the Address
Overview, see page 43.
The bit and word data correlate to internal memory as follows:

6. Configuration
6.1 Configuring the Anybus Communicator CAN
The configuration of the Anybus Communicator CAN is performed using the configuration tool Anybus Configuration Manager for Communicator CAN (ACM). The tool is included on the CD that accompanies the module, and it is also available for download at ‘www.anybus.com’. Chapters 7 to 12 in
this manual describe the configuration tool and its features. A configuration example is given in Appendix B on page 51.
The USB connector at the bottom of the module is used for uploading and downloading the configuration. Please remove the USB cable when the configuration of the Communicator is finished.
6.2 Configuring the CC-Link Network
The Anybus Communicator CAN - CC-Link is a CC-Link slave on the CC-Link network. The general
settings for the adapter interface are configured using the ACM (see “Network Settings” on page 29).
Please note that the size of the I/O data that can be read from and written to the module is defined when
configuring the Communicator using the ACM tool.
The CC-Link slave interface of the Communicator is configured within the configuration of the CCLink network. An application note is available on the support pages for the Anybus Communicator
CAN - CC-Link module at ‘www.anybus.com’.

7. Anybus Configuration Manager
The Anybus Configuration Manager (ACM) is used to configure all aspects of the Communicator CAN.
It also provides different tools for monitoring the module and the CAN subnetwork.
Note: The configuration manager automatically allocates addresses and memory space in the input and
output areas of the Communicator for the data objects that are configured. It is possible to change these
addresses, but it is recommended to finish the configuration using default addresses before starting to
change any addresses. A valid address range is always shown in the information section of the main window.

9. Groups and Transactions
9.1 General
The configuration of the Communicator is set up in groups, each containing one or more transactions.
Please note that the groups do not represent a physical device on the CAN network. They are a means
for structuring the application, and maintaining an overview of it. The maximal number of groups is 128.
A transaction can be either a Produce, a Consume or a Query/Response transaction. Each transaction
holds one or more CAN frames, which transport the data on the network. A total of 128 transactions is
allowed, and a total of 256 CAN frames.
Each CAN frame can hold up to 8 bytes of data.
Groups and transactions as well as frames and objects (described in the next section) can be copied and
pasted in the configuration tree, but only at the same level as they were copied from, or their parent.
9.2 Groups
To create a group, right click on ‘Subnetwork’ and select ‘Add Group’. The name
of the group can be changed by selecting
‘Group’ and then entering a new name at
‘Group Alias‘.
If you want to insert another group, right
click on ‘Subnetwork’ once more. The
new group will be added to the end of the list of groups.
If you right click on a group and select ‘Insert Group’, the new group will be inserted before the selected
group.
It is recommended to change the group name, to better present the configuration.
9.3 Transactions
There are five kinds of transactions: Produce,
Consume, Query/Response, Dynamic Produce
and Dynamic Consume.
Selecting the transaction will give the option to
give the transaction an alias. The order of the
transactions in the tree is given as the transaction
number in the parameter section. Each transaction number corresponds to a bit in the transaction live list that can be mapped to the input data
area.
Note: The transaction live list is always available
in the Diagnostics/Status window, even when it is
not mapped to the input data area in the memory.

To add a transaction to the group, right click on the group and select either
Add Produce, Add Consume, Add Query/Response, Add Dynamic Produce or Add Dynamic Consume.
Each transaction holds one CAN frame by default when added to a group.
The dynamic transactions can not hold more than one CAN frame.
9.3.1 Produce
A produce transaction transmits CAN frames
on the CAN network for all devices on the
network to listen to. A CAN device on the
network will use the identifier of the produce
transaction to decide if the data is meant for it
or not. The Communicator operates as any
other device on the CAN network, that produces and transmits data on the network. Selecting ‘Produce’ gives access to the following parameters:

9.3.3 Query/Response
In Query/Response mode the Communicator operates as a master and issues queries to the CAN network. The Communicator will then expect a response within the specified timeout. A Query/Response transaction
includes both query CAN frames and response CAN frames.
Selecting Query will give the same options as selecting Produce, except ‘Update on RTR’, see:
•
“Produce” on page 31.
Selecting Response will give the same options as selecting Consume, see
•
“Consume” on page 32.
Please note that the Offline Timeout value indicates the maximum time that the Communicator will wait
for an answer before an error is issued. For a cyclic query, the offline timeout must be lower than the
update time.

10. Configuration of CAN Frames
10.1 General
Each transaction includes one or more CAN frames. A total of 256 CAN frames is allowed. Right-clicking on a transaction will give the opportunity to add another frame to the transaction.
The Anybus Configuration Manager makes it possible to decide the configuration of the 8 bytes of data
that can be included in each frame. The configuration manager automatically allocates memory space in
the input and output areas of the Communicator for the data objects that are configured in the frames.
The result can be seen in the Address Overview, see page 43. Any address conflicts will turn up red in
this view.
Note: A CAN frame can not contain more than 8 bytes of data. It is possible to configure the data area
in each frame, but the size of the combination of objects must not exceed 8 bytes.
10.1.1 CAN Identifiers
Each frame has a CAN identifier, to make it possible for each node on the CAN network to recognize
data meant for it. Default identifier is ‘0’. It can be changed by selecting the CAN Frame and enter the
new CAN Identifier in the Parameter window.
The CAN frame has either a 11-bit identifier or a 29-bit identifier. If the size of the identifier is changed,
an 11-bit identifier will have the 11 original bits padded with zeroes in front. A 29 bit identifier will have
its 18 highest bits cut, which may cause a not valid 11-bit identifier.
It is possible to have several frames in one transaction. The first frame in a Consume or Response transaction must have a CAN identifier that does not appear in any other Consume or Response transaction.
Consecutive frames within a received transaction may have the same identifier, on two conditions:
•
The first part of the data area in the frame is a byte, word or Dword constant with a unique value
compared to other frames with the same identifier within the transaction.
•
If any frame with another identifier is added to the transaction, it must not break the sequence
of frames with identical identifiers.

2. Choose industrial network. The example is the same
irrespective of industrial network, but in an application it
is important to choose network first, as the ACM will
show the amount of data that can be transferred.

3. Select ‘Communicator’.
- Enable the Control/Status Word.
If the Control/Status Word is to be used in a
configuration, it is recommended to enable it
before adding any transactions to the configuration. The Control/Status Word is positioned
at the start of the memory, and this may cause
address conflicts if any data objects have been
configured previously.
For more information on the Control/Status
Word, see page 18.
- Leave the rest of the parameters at default values.

4. Select ‘Subnetwork’.
If the Control/Status Word is enabled no Bus Off Action can be defined.
5. Add Groups.
- Right-click on ‘Subnetwork’ and add two groups
to the navigation tree, one for each device on the
CAN network.
- Rename them e.g. Temp. Sensor and Motor. Renaming is essential to enable other users than
the designer of the application to comfortably
monitor and modify the application.
The CAN network is message-based, but using the group to structure the transactions will make
it conceptually easier to build a configuration.
6. Add transactions to Temp. Sensor group.
The temperature sensor needs to be initialized. It
needs instructions during runtime, and it will deliver
temperature data to the Communicator.
A suitable transaction for an initialization is a queryresponse transaction which is run once at start up.
A query-response transaction ensures an acknowledgement of a successful initialization. In this example, the initialization is performed in two steps.
Also, instructions and information need to be sent
to the sensor and data collected. A produce transaction sends information to the network and a consume transaction will collect information.
- Add two query-response transactions and rename them ‘Initialize 1’ and ‘Initialize 2’.
- On each, select Query and change Update Mode to Single Shot. The transactions will be run
once at startup to initialize the communication with the temperature sensor.
- Leave the rest of the parameters at default values.
- Add one Produce transaction to send information and instructions to the temperature sensor. Rename the transaction to ‘Cels/Farenh’ and set Update Mode to Cyclically.
- Leave the rest of the parameters at default values.
- Finally add one Consume transaction to collect the data cyclically from the temperature sensor. Rename the transaction to ‘Temperature’ and set Update Mode to Cyclically.
- Leave the rest of the parameters at default values.

7. Add frames to the transactions.
- Right-click on ‘Query’ in ‘Initialize 1’ and add a CAN
frame.
- Select the frame.
- Set a unique CAN identifier to the frame. The CAN
identifier shall be recognized on the network by the
temperature sensor.
- Right click on the frame to define the components of
the 8 byte data area in the frame, see figure to the right.
- Enter constant values where applicable.
- Right-click on ‘Response’ in ‘Initialize 1’ and repeat the
procedure.
Addresses in the input and output areas of the internal
memory will automatically be allocated to the data objects.
It is possible to change these addresses, but it is recommended to finish configuration using default values. If any
collisions appear, the addresses can be changed at a later
stage. The ACM will not allow you to add a data or a constant object, that is larger than the remaining data area in the selected frame.
8. Repeat according to step 7 to add frames and contents to ‘Initialize 2’, ‘Cels/Farenh’ and ‘Temperature’.
9. Add transactions to Motor group.
The motor needs to be initialized. It also needs instructions during runtime, and it will return status
information to the Communicator. It is also possible to remotely set the speed of the motor.
- Add a query-response transaction and rename it
‘Initialize’.
- Select Query and change Update Mode to Single
Shot.
- Add one Query-Response transaction (‘Motor Control’) to control the motor during runtime.
- Set Update Mode to On Data Change.
- Add one Consume transaction (‘Motor Status’) to collect status cyclically from the motor.
- Finally add a Produce transaction (‘Speed’) to be able to change the speed of the motor.

10. Add frames to the transactions, see step 7 above.
11. Check the validity of configuration in
the Diagnostics/Status window.
If address conflicts are present, check the
Address Overview to see which transactions cause the conflict. Change the addresses of the data objects in the frames to
remove conflicts.
12. Download the configuration to the Communicator using the USB connection. Remove the USB
cable when finished
A configuration can be saved at any time and opened at a later time for editing. Once it is valid it can be
downloaded to the Anybus Communicator CAN.
