1. About the Anybus CompactCom 30 DeviceNet
1.1 General
The Anybus CompactCom 30 DeviceNet communication module provides instant DeviceNet connectivity via the patented Anybus CompactCom host interface. Any device that supports this standard can
take advantage of the features offered by the module, allowing seamless network integration regardless
of network type.
The modular approach of the Anybus CompactCom platform allows the CIP-object implementation to
be extended to fit specific application requirements. Furthermore, the Identity Object can be customized, allowing the end product to appear as a vendor-specific implementation rather than a generic Anybus module.
This product conforms to all aspects of the host interface for Active modules defined in the Anybus
CompactCom 30 Hardware- and Software Design Guides, making it fully interchangeable with any other device following that specification. Generally, no additional network related software support is needed, however in order to be able to take full advantage of advanced network specific functionality, a
certain degree of dedicated software support may be necessary.

Chapter 2
2. Tutorial
2.1 Introduction
This chapter is a complement to the Anybus CompactCom Implementation Tutorial. The ABCC tutorial describes and explains a simple example of an implementation with Anybus CompactCom. This
chapter includes network specific settings that are needed for a host application to be up and running
and possible to certify for use on DeviceNet networks.
2.2 Fieldbus Conformance Notes
•
The Anybus CompactCom 30 DeviceNet has been pre-compliance tested by ODVA’s authorized Independent Test Lab and found to comply with the ODVA Conformance Test Software.
However, in accordance with ODVA’s conformance test policy, the final product must still be
compliance tested to ensure fieldbus conformance. In order to be able to do this, the vendor information in the DeviceNet Host Object must be customized.
•
It is strongly recommended to customize the information in the Identity Object (CIP), to enable
the product to appear as a vendor specific implementation rather than a generic Anybus module.
ODVA requires that all manufacturers use their own Vendor ID. A Vendor ID can be applied
for from ODVA.
For further information, please contact HMS or ODVA.
2.3 Conformance Test Guide
When using the default settings of all parameters, the Anybus CompactCom 30 DeviceNet module is
precertified for network compliance. This precertification is done to ensure that your product can be certified, but it does not mean that your product will not require certification.
Any change in the parameters in the EDS file, supplied by HMS, will require a certification. A Vendor
ID can be obtained from ODVA and is compulsory for certification. This section provides a guide for
successful conformance testing your product, containing the Anybus CompactCom 30 DeviceNet module, to comply with the demands for network certification set by the ODVA.
Independent of selected operation mode, the actions described in this section have to be accounted for
in the certification process. The identity of the product needs to be changed to match your company and
device.
IMPORTANT: This section provides guidelines and examples of what is needed for certification. Depending on the
functionality of your application, there may be additional steps to take. Please contact HMS Industrial Networks at
www.anybus.com for more information.

a. The Device Type default value 0000h must be changed for the module to pass a conformance test. If no other
specific profile is implemented, use the value 002Bh (Generic Device (keyable)).
2.3.2 Factory Default Reset
Reset command to Application Object (FFh) must be supported
When Anybus CompactCom 30 DeviceNet modules are delivered, they are required to be in their “Factory Default” state. When a Factory Default Reset command is received from the network, the Anybus
module will erase all non-volatile information and inform the host application that a reset of the Anybus
module is required. This is done by sending a Reset command to the Application Object (FFh) of the
host (Power-on + Factory Default). For more details, please consult the Anybus CompactCom 30 Software Design Guide.

3. Basic Operation
3.1 General Information
3.1.1 Software Requirements
Generally, no additional network support code needs to be written in order to support the Anybus CompactCom DeviceNet. However, due to the nature of the DeviceNet networking system, certain restrictions must be taken into account:
•
Certain functionality in the module requires that the command ‘Get_Instance_Number_By_Order’ (Application Data Object, FEh) is implemented in the host application.
•
Up to 5 diagnostic instances (See “Diagnostic Object (02h)” on page 36) can be created by the
host application during normal conditions. An additional 6th instance may be created in event of
a major fault.
For in-depth information regarding the Anybus CompactCom software interface, consult the general
Anybus CompactCom Software Design Guide.
See also...
•
“Diagnostic Object (02h)” on page 36 (Anybus Module Object)
•
Anybus CompactCom Software Design Guide, ‘Application Data Object (FEh)’
3.1.2 Electronic Data Sheet (EDS)
Since the module implements the Parameter Object, it is possible for configuration tools such as RSNetWorx to automatically generate a suitable EDS-file.
Note that this functionality requires that the command ‘Get_Instance_Number_By_Order’ (Application Data Object, FEh) has been implemented in the host application.
See also...
•
“Device Customization” on page 12
•
“Parameter Object (0Fh)” on page 28 (CIP-object)
•
Anybus CompactCom Software Design Guide, ‘Application Data Object (FEh)’
IMPORTANT: To comply with CIP-specification requirements, custom EDS-implementations require a new Vendor
ID and/or Product Code.
To obtain a Product Code which complies to the default Vendor ID, please contact HMS.

Basic Operation 12
3.2 Device Customization
By default, the module supports the generic CIP-profile with the following identity settings:
•
Vendor ID:
005Ah (HMS Industrial Networks)
•
Device Type:
0000h (Generic Device)
•
Product Code:
0062h (Anybus CompactCom DeviceNet)
•
Product Name:
‘Anybus-CC DeviceNet’
It is possible to customize the identity of the module by implementing the DeviceNet Host Object. Furthermore, it is possible to re-route requests to unimplemented CIP-objects to the host application, thus
enabling support for other profiles etc.
To support a specific profile, perform the following steps:
•
Set up the identity settings in the DeviceNet Host Object according to profile requirements.
•
Set up the Assembly Instance Numbers according to profile requirements.
•
Enable routing of CIP-messages to the host application in the DeviceNet Host Object.
•
Implement the required CIP-objects in the host application.
See also...
•
“Identity Object (01h)” on page 16 (CIP-object)
•
“DeviceNet Host Object (FCh)” on page 42 (Host Application Object)
•
“CIP Request Forwarding” on page 49
IMPORTANT: The default identity information is valid only when using the standard EDS-file supplied by HMS.
To comply with CIP-specification requirements, custom EDS-implementations require a new Vendor ID and/or Product
Code.
To obtain a Product Code which complies to the default Vendor ID, please contact HMS.
3.3 Communication Settings
As with other Anybus CompactCom products, network related communication settings are grouped in
the Network Configuration Object (04h).
In this case, this includes...
•
Baud rate
See “Instance Attributes (Instance #2, ‘Baud rate’)” on page 39
•
MAC ID
See also... “Setting MAC ID” on page 13
The parameters in the Network Configuration Object (04h) are available from the network through the
Identity Object (CIP-object).

Basic Operation 13
3.3.1 Setting MAC ID
There are three different methods to set the MAC ID (the node address) of the module.
Actions Required to be Performed by Host
Application
Node address set only • Set attribute #5 in the Network Configurafrom network
tion Object (04h), Instance #1 to any value
between 64 - 255.
• Set attribute #9 in the DeviceNet Object
(FCh) to TRUE.
Method
Node address set only
from application
Node address set from
network or from application
• Set attribute #9 in the DeviceNet Object
(FCh) to FALSE.
• Set attribute #5 in the Network Configuration Object (04h), Instance #1 to any value
between 0 - 63.
• Each time the host application changes the
value, the new value shall be written to attribute #5 in the Network Configuration Object
(04h), Instance #1.
• Set attribute #5 in the Network Configuration Object (04h), Instance #1.
• Each time the host application changes the
value, the new value shall be written to attribute #5 in the Network Configuration Object
(04h), Instance #1.
• Set attribute #9 in the DeviceNet Object
(FCh) to TRUE.
Comments
An invalid device (node) address (64 - 255) is
set in the application. The network will write a
valid node address to the Network Configuration object. The module deletes all Connection
objects and restarts the network access process.
If an invalid value is set by the application (64 255), the module will enter the “Communication
faulted state” at network initialization.
If an invalid value is set by the application, the
module will return to the last used .
When a device adress is set from the network,
the address will be set in attribute #5 in the Network Configuration Object (04h), Instance #1.
The module deletes all Connection objects and
restarts the network access process.

3.5 Data Exchange
3.5.1 Application Data (ADIs)
ADIs are represented on DeviceNet through the ADI Object (CIP-object). Each instance within this
objects corresponds directly to an instance in the Application Data Object on the host application side.
See also...
•
“Parameter Object (0Fh)” on page 28 (CIP-object)
•
“ADI Object (A2h)” on page 31 (CIP-object)
3.5.2 Process Data
Process Data is represented on DeviceNet through dedicated instances in the Assembly Object. Note
that each ADI element is mapped on a byte-boundary, i.e. each BOOL occupies one byte.
See also...
•
“Assembly Object (04h)” on page 21 (CIP-object)
•
“Connection Object (05h)” on page 23 (CIP-object)

4.7 Parameter Object (0Fh)
Category
Extended
Object Description
This object allows configuration tools such as RSNetworx to extract information about the Application
Data Instances (ADIs) and present them with their actual name and range to the user.
Since this process may be somewhat time consuming, especially when using the serial host interface, it
is possible to disable support for this functionality in the DeviceNet Host Object.
Due to limitations imposed by the CIP standard, ADIs containing multiple elements (i.e. arrays etc) cannot be represented through this object. In such cases, default values will be returned, see 4-29 “Default
Values”.

6.2 DeviceNet Host Object (FCh)
Category
Basic, extended, advanced
Object Description
This object implements DeviceNet specific settings in the host application. It is also used when implementing DeviceNet classes in the host application, e.g. when creating profile implementations etc.
The implementation of this object is optional; the host application can support none, some, or all of the
attributes specified below. The module will attempt to retrieve the values of these attributes during startup; if an attribute is not implemented in the host application, simply respond with an error message (06h,
“Invalid CmdExt[0]”). In such case, the module will use its default value.
If the module attempts to retrieve a value of an attribute not listed below, respond with an error message
(06h, “Invalid CmdExt[0]”).

Command Code.: 10h
Valid for:
Object Instance
Description
By setting the ‘Enable CIP Request Forwarding’-attribute (#11), all requests to unimplemented CIP-objects or unimplemented assembly object instances will be forwarded to the host application. The application then has to evaluate the request and return a proper response.
The module supports up to 6 pending CIP-requests; additional requests will be rejected by the module.
Note: This command is similar - but not identical - to the ‘Process_CIP_Message_Request’-command
in the Anybus CompactCom EtherNet/IP.

Appendix A
A. Categorization of Functionality
The objects, including attributes and services, of the Anybus CompactCom and the application are divided into three categories: basic, advanced and extended.
A.1 Basic
This category includes objects, attributes and services that are mandatory to implement or to use. They
will be enough for starting up the Anybus CompactCom and sending/receiving data with the chosen
network protocol. The basic functions of the industrial network are used.
Additional objects etc, that will make it possible to certify the product also belong to this category.
A.2 Extended
Use of the objects in this category extends the functionality of the application. Access is given to the
more specific characteristics of the industrial network, not only the basic moving of data to and from
the network. Extra value is given to the application.
A.3 Advanced
The objects, attributes and services that belong to this group offer specialized and/or seldom used functionality. Most of the available network functionality is enabled and accessible. Access to the specification of the industrial network is normally required.

Appendix B
B. Implementation Details
B.1 DeviceNet Implementation
Predefined Connection Set
The module acts as a Group 2 server and supports the Predefined Master/Slave Connection Set.
•
COS Connection
When the master allocates this connection type, the module transmits the Process Data it changes. An inhibit time can be set to prevent the module from sending too often.
The module supports up to 256 bytes in each direction for this type of connection. The size of
the connection is checked against the number of bytes mapped as Process Data.
•
Cyclic Connection
When the master allocates this connection type, the module cyclically transmits the Process Data
at the configured interval.
The module supports up to 256 bytes in each direction for this type of connection.
•
Bit Strobe Connection
When the master allocates this connection type, the module transmits data when the bit strobe
message is received. The module only uses the input bit if no other I/O connections have been
configured, and produces up to 8 bytes.
•
Polled Connection
When the master allocates this connection type, the module transmits the Process Data data
when a poll command is received.
The module supports up to 256 bytes in each direction for this type of connection.
•
Explicit Connection
The predefined explicit connection has a buffer of 262 bytes.
•
Idle/Running
The module is considered to be in Idle mode when not receiving any DeviceNet telegrams, or
when receiving DeviceNet telegrams with no data. In other cases, the module is considered to
be in Run mode.
This affects the Anybus State machine as describe in B-48 “Anybus State Machine”.
Unconnected Message Server (UCMM)
The module is a UCMM capable device, and supports the Unconnected Explicit Message Request port,
Group3, Message ID=6.
•
Explicit Message Server
The module supports up to 5 simultaneous explicit message connections.

B.2 SUP-Bit Definition
The supervised bit (SUP) indicates that the network participation is supervised by another network device. For DeviceNet this bit is set when the connection object has a connection.
B.3 Anybus State Machine
The table below describes how the Anybus State Machine relates to the DeviceNet network. status
State
WAIT_PROCESS
ERROR
DeviceNet Specific Meaning
The module will stay in this state until a Class
0 connection is opened.
Class 0 connection error, bus off event
detected or dup-MAC-fail
PROCESS_ACTIVE Error free Class 0 connection active
IDLE
Class 0 connection idle
EXCEPTION
Some kind of unexpected behaviour, e.g.
watchdog timeout.
Anybus CompactCom 30 DeviceNet
Doc.Rev. 2.40
Notes
(Not set for explicit connections.)
If the error is fatal, such, such as dup-MAC-fail
or bus off, the module will stay in this state until
it’s restarted.
Can only be set for connections consuming
data.
The Module Status LED will turn red to indicate a major fault, and turn the Network Status
LED off.
Doc.Id. HMSI-168-51
Appendix C
C. CIP Request Forwarding
If CIP request forwarding is enabled (DeviceNet Host Object, Instance 1, Attribute 11), all network requests to unknown CIP objects or unknown assembly object instances will be forwarded to the host
application. For this purpose, the DeviceNet Host Object implements a command called
Process_CIP_Message_Request (Command code 10h), which is used to tunnel CIP requests to the host
application.
Note: CIP requiest forwarding is only relevant for explicit messages. It is not applicable to the messages
that carry the cyclic/process data.
Since the telegram length on the host interface is limited, the request data size must not exceed 255 bytes.
If it does, a the module will send a ‘resource unavailable’ response to the originator of the request and
the message will not be forwarded to the host application.
•
Command Message Layout
This message will be sent by the module to the host application upon receiving an unknown CIP
request from the network.

•
Route CAN_H and CAN_L side by side with similar lengths. Use Shield as a reference plane for
this signal pair and for V+ and V-.
•
If the device is designed with one fieldbus connecoter e.g. a screw terminal, it is recommended
to connect CAN-H and CAN-L only to pins 3 and 5 of the brick header.
•
If the device is designed with two fieldbus connectors, e.g. M12 connectors, it is recommended
to use brick header pins 3 and 5 for one of the connectors, while pins 15 and 16 are used for the
other connector. Which one of the connectors that is used as input or output does not matter.
Route V+and V- with thic traces directly between the connectors.

Technical Specification 54
D.3 Protective Earth (PE) Requirements
In order to ensure proper EMC behaviour, the module must be properly connected to protective earth
via the PE pad / PE mechanism described in the general Anybus CompactCom Hardware Design
Guide.
HMS Industrial Networks does not guarantee proper EMC behaviour unless these PE requirements are
fulfilled.
D.4 Power Supply
Supply Voltage
The module requires a regulated 3.3 V power source as specified in the general Anybus CompactCom
Hardware Design Guide.
Power Consumption
The Anybus CompactCom DeviceNet is designed to fulfil the requirements of a Class A module. For
more information about the power consumption classification used on the Anybus CompactCom platform, consult the general Anybus CompactCom Hardware Design Guide.
The current hardware design consumes up to 65 mA1.
Note: It is strongly advised to design the power supply in the host application based on the power consumption classifications described in the general Anybus CompactCom Hardware Design Guide, and
not on the exact power requirements of a single product.
D.5 DeviceNet Power Supply
The total number of units that can be connected to the DeviceNet bus is limited by the maximum current that the power supply can deliver to the bus. Maximum current consumption per unit is specified
in the DeviceNet specification to 750 mA. If e.g. the supply can deliver 9 A and all units consume maximum current, the maximum numbers of units allowed on the bus are 12 (12x750 mA = 9A).
The Anybus CompactCom 30 DeviceNet module accepts 11 - 25 V on the industrial network side of
the module. Maximum current consumption at 11 - 25 V is 36 - 38 mA/module.
Note: If the M12 version of the module is used, the current on the DeviceNet bus has to be limited to
a maximum of 3 A, which is the max. current allowed for the M12 connectors.
D.6 Environmental Specification
Consult the Anybus CompactCom Hardware Design Guide for further information.
D.7 EMC Compliance
1. Note that in line with HMS policy of continuous product development, we reserve the right to change the
exact power requirements of this product without prior notification. Note however that in any case, the
Anybus CompactCom DeviceNet will remain as a Class A module.
