About the Anybus CompactCom 40 Common
Ethernet
2.1
General
The Anybus CompactCom 40 Common Ethernet communication module provides a common
platform for the Industrial Ethernet networks, that are supported in the Anybus CompactCom 40
product family. The communication software for the selected network is downloaded to the module and the module will seamlessly integrate to the network. It is also possible to use the module
as a general Ethernet interface, using the included TCP/IP stack (See Socket Interface Object
(07h), p. 65). The modular approach of the Anybus CompactCom 40 platform allows the module
to 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 Anybus CompactCom 40 modules defined in the Anybus CompactCom 40 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.

Socket Interface (Advanced Users Only)
The built in socket interface allows additional protocols to be implemented on top of TCP/IP. Data is structured by the application and is then embedded within the Ethernet frames. The host
application can open network connections of its own to other nodes on the network, e.g. if you
want to connect to another server or use a web server of your own.

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...
TCP/IP settings
These settings must be set properly in order for the module to be able to
participate on the network.
The module supports DHCP, which may be used to retrieve the TCP/IP settings
from a DHCP-server automatically. DHCP is enabled by default, but can be
disabled if necessary.
Physical Link Settings
By default, the module uses auto negotiation to establish the physical link
settings, however it is possible to force a specific setting if necessary.
The parameters in the Network Configuration Object (04h) are available from the network
through the built in web server.

Communication Settings in Stand Alone Shift Register Mode
If the Anybus CompactCom 40 is used stand alone, there is no application from which to set the
IP address. The IP address is instead set using the DIP1 switches (IP address byte 3) and the
virtual attributes (Ethernet Host object (F9h), attribute #17), that are written to memory during
setup (IP address byte 0 - 2). A flowchart is shown below.

File System
Category: Extended
3.7.1
Overview
The Anybus CompactCom 40 Common Ethernet has an in-built file system, that can be accessed from the application and from the network. Three directories are predefined:
VFS
The virtual file system that e.g. holds the web pages of the module. The virtual file
system is enabled by default in the Anybus File System Interface Object (0Ah).
Application
This directory provides access to the application file system through the
Application File System Interface Object (EAh) (optional).
Firmware
Firmware updates are stored in this directory.
In the firmware folder, it is not possible to use append mode when writing a file. Be sure to use
write mode only.

General Information
The built-in file system hosts 28 MByte of non volatile storage, which can be accessed by the
HTTP and FTP servers, the email client, and the host application (through the Anybus File System Interface Object (0Ah)).
The maximum number of directories and files, that can be stored in the root directory, is 511 if
only short filenames are used (8 bytes name + 3 bytes extension). The number of files that can
be stored in other directories, than the root directory, is unlimited.
The file system uses the following conventions:
•
\ (backslash) is used as a path separator
•
Names may contain spaces, but must not begin or end with one.
•
Valid characters in names are ASCII character numbers less than 127, excluding the following characters: \ / : * ? “ < > |
•
Names cannot be longer than 48 characters
•
A path cannot be longer than 126 characters (filename included)

The file system is located in flash memory. Due to technical reasons, each flash
segment can be erased approximately 100000 times before failure, making it
unsuitable for random access storage.
The following operations will erase one or more flash segments:
3.7.3
•
Deleting, moving or renaming a file or directory
•
Writing or appending data to an existing file
•
Formatting the file system
System Files
The file system contains a set of files used for system configuration. These files, known as “system files”, are regular ASCII files which can be altered using a standard text editor (such as the
Notepad in Microsoft Windows™). The format of these files are, with some exceptions, based on
the concept of keys, where each key can be assigned a value, see below.
Example 1:
[Key1]
value of Key1
[Key2]
value of Key2

FTP Server
5.1
General Information
The built-in FTP-server makes it easy to manage the file system using a standard FTP client. It
can be disabled using attribute #6 in the Ethernet Host Object (F9h).
By default, the following port numbers are used for FTP communication:
•
TCP, port 20 (FTP data port)
•
TCP, port 21 (FTP command port)
The FTP server supports up to two concurrent clients.
5.2
User Accounts
User accounts are stored in the configuration file \ftp.cfg. This file holds the usernames, passwords, and home directory for all users. Users are not able to access files outside of their home
directory.
File Format:
User1:Password1:Homedirectory1
User2:Password2:Homedirectory2
User3:Password3:Homedirectory3
Optionally, the UserN:PasswordN-section can be replaced by a path to a file containing a list of
users as follows:
File Format (\ftp.cfg):
User1:Password1:Homedirectory1
User2:Password2:Homedirectory2
.
.
UserN:PasswordN:HomedirectoryN
\path\userlistA:HomedirectoryA
\path\userlistB:HomedirectoryB
The files containing the user lists shall have the following format:
File Format:
User1:Password1
User2:Password2
User3:Password3
.
.
.UserN:PasswordN
Notes:
•
Usernames must not exceed 16 characters in length.
•
Passwords must not exceed 16 characters in length.
•
Usernames and passwords must only contain alphanumeric characters.

•
If \ftp.cfg is missing or cannot be interpreted, all username/password combinations will be
accepted and the home directory will be the FTP root (i.e. \ftp\).
•
The home directory for a user must also exist in the file system, if the user shall be able to
log in. It is not enough just to add the user information to the ftp.cfg file.
•
If Admin Mode has been enabled in the Ethernet Object, all username/password combinations will be accepted and the user will have unrestricted access to the file system (i.e. the
home directory will be the system root). The vfs folder is read-only.
•
It is strongly recommended to have at least one user with root access (\) permission. If not,
Admin Mode must be enabled each time a system file needs to be altered (including \ftp.
cfg).
Session Example
The Windows Explorer features a built-in FTP client which can easily be used to access the file
system as follows:
1.
Open the Windows Explorer.
2.
In the address field, type FTP://<user>:<password>@<address>
3.
–
- Substitute <address> with the IP address of the Anybus module
–
- Substitute <user> with the username
–
- Substitute <password> with the password
Press Enter. The Explorer will now attempt to connect to the Anybus module using the
specified settings. If successful, the file system will be displayed in the Explorer window.

Web Server
6.1
General Information
Category: extended
The built-in web server provides a flexible environment for end-user interaction and configuration purposes. The powerful combination of JSON, SSI, and client-side scripting allows access
to objects and file system data, enabling the creation of advanced graphical user interfaces.
The web interface is stored in the file system, which can be accessed through the FTP server. If
necessary, the web server can be completely disabled in the Ethernet Host Object.
The web server supports up to TBD concurrent connections and communicates through port 80.

Default Web Pages
The default web pages provide access to:
•
Network configuration parameters
•
Network status information
•
Access to the host application ADIs
The default web pages are built of files stored in a virtual file system accessible through the vfs
folder. These files are read only and cannot be deleted or overwritten. The web server will first
look for a file in the web root folder. If not found it will look for the file in the vfs folder, making it
appear as the files are located in the web root folder. By loading files in the web root folder with
exactly the same names as the default files in the vfs folder, it is possible to customize the web
pages, replacing such as pictures, logos and style sheets.
If a complete customized web system is designed and no files in the vfs folder are to be used, it
is recommended to turn off the virtual file system completely, see the File System Interface
Object.

Directories can be protected from web access by placing a file called “web_accs.cfg” in the directory to protect. This file shall contain a list of users that are allowed to access the directory
and its subdirectories.
Optionally, a login message can be specified by including the key [AuthName]. This message
will be displayed by the web browser upon accessing the protected directory.

E-mail Client
7.1
General Information
The built-in e-mail client allows the application to send e-mail messages through an SMTP-server. Messages can either be specified directly in the SMTP Client Object (04h), or retrieved from
the file system. The latter may contain SSI, however note that for technical reasons, certain
commands cannot be used (specified separately for each SSI command).
The client supports authentication using the ‘LOGIN’ method. Account settings etc. are stored
in the Network Configuration Object (04h).
7.2
How to Send E-mail Messages
To be able to send e-mail messages, the SMTP-account settings must be specified.
This includes:
•
A valid SMTP-server address
•
A valid username
•
A valid password
To send an e-mail message, perform the following steps:
1.
Create a new e-mail instance using the Create command (03h)
2.
Specify the sender, recipient, topic and message body in the e-mail instance
3.
Issue the Send Instance Email command (10h) towards the e-mail instance
4.
Optionally, delete the e-mail instance using the Delete command (04h)
Sending a message based on a file in the file system is achieved using the Send Email from File
command. This command is described in the SMTP Client Object (04h).

printf()
This function returns a formatted string which may contain data from the Anybus CompactCom
module and/or application. The formatting syntax used is similar to that of the standard C-function printf().
The function accepts a template string containing zero or more formatting tags, followed by a
number of arguments. Each formatting tag corresponds to a single argument, and determines
how that argument shall be converted to human readable form.
Syntax:
<?--#exec cmd_argument='printf("template" [, argument1, ..., argumentN])'-->
template:
Template which determines how the arguments shall be represented. May contain any
number of formatting tags which are substituted by subsequent arguments and formatted as requested. The number of format tags must match the number of arguments; if
not, the result is undefined.

scanf()
This function is very similar to the printf() function described earlier, except that it is used for input rather than output. The function reads a string passed from an HTML form object, parses
the string as specified by a template string, and sends the resulting data to the specified argument. The formatting syntax used is similar to that of the standard C-function scanf().
The function accepts a source, a template string containing zero or more formatting tags, followed by a number of arguments. Each argument corresponds to a formatting tag, which determines how the data read from the HTML form shall be interpreted prior sending it to the
destination argument.
This command cannot be used in e-mail messages.

Optionally, it is possible to exchange the BOOL data with a message based on the value (true or false). In such case, the actual

This type can also be used when reading ENUM data types from
an object. In such case, the actual ENUM value will be returned.
When using this data type, the ABCCMessage() function will first
read the ENUM value. It will then issue a ‘Get Enum String’-command to retrieve the actual enumeration string. The actual data
type in the response will be STRING.
Response holds no data, hence no data type
It is important to note that the message will be passed transparently to the
addressed object. The SSI engine performs no checks for violations of the object
addressing scheme, e.g. a malformed Get_Attribute request which (wrongfully)
includes message data will be passed unmodified to the object, even though this is
obviously wrong. Failure to observe this may cause loss of data or other undesired
side effects.

SSI Output Configuration
Optionally, the SSI output can be permanently changed by adding the file \output.cfg.
File format:
[ABCCMessage_X]
0:“Success string”
1:“Error string 1”
2:“Error string 2”
...
16“:Error string 16”
Each error code corresponds to a dedicated output string, labelled from 1 to 16.
See Errors, p. 43
[GetConfigItem_X]
0: “Success string”
1:“Authentication error string”
2:“File open error string”
3:“Tag not found string”
Use “%s” to include the name of the file.
[SetConfigItem_X]
0: “Success string”
1:“Authentication error string”
2:“File open error string”
3:“File write error string”
Use “%s” to include the name of the file.
[IncludeFile_X]
0: “Success string”
1:“Authentication error string”
2:“File read error string”
Use “%s” to include the name of the file.
[scanf_X]
0: “Success string”
1:“Parsing error string”
-
[ChangeLanguage_X]
0: “Success string”
1:“Change error string”
-
All content above can be included in the file multiple times changing the value “X” in each tag
for different languages. The module will then select the correct output string based on the language settings. If no information for the selected language is found, it will use the default SSI
output.

JSON
9.1
General Information
JSON is an acronym for JavaScript Object Notation and an open standard format for storing
and exchanging data in an organized and intuitive way. It is used as an alternative to XML, to
transmit data objects consisting of attribute - value pairs between a server and a web application. JavaScripts are used to create dynamic web pages to present the values.
JSON is more versatile than SSI in that you not only can change the values on a web page, but
also the size and the look of the web page dynamically. A simple example of how to create a
web page is added at the end of this chapter.
JSON requests shall be UTF-8 encoded. The module will interpret JSON requests as UTF-8 encoded, while all other HTTP requests will be interpreted as ISO-8859-1 encoded. All JSON responses, sent by the module, are UTF-8 encoded, while all other files sent by the web server
are encoded as stored in the file system.
9.1.1
Access
The JSON resources should be password protected. Add password protection by adding a file
called web_accs.cfg in the root directory.

Hex Format Explained
The metadata max and min fields and the ADI values are ABP data encoded in a hex format. If
the data type is an integer, the endianness used is determined by the data format field found in
adi/info.json.
Examples:
The value 5 encoded as a UINT16, with data format = 0 (little endian):
0500
The character array “ABC” encoded as CHAR[3] (data format is not relevant for CHAR):

If the socket is of TCP-type and a connection is established, the connection is terminated with the RSTflag.
•
To gracefully terminate a TCP-connection, it is recommended to use the ‘Shutdown’-command (see below) before deleting the socket, causing the connection to be closed with the FIN-flag instead.

The recommended sequence to gracefully shut down a TCP connection is described below.
Application initiates shutdown:
1.
Send shutdown with CmdExt[1] set to 01h. This will send FIN-flag to host shutting down the send channel, note that the receive channel will still be operational.
2.
Receive data on socket until error message Object specific error (EPIPE (13)) is received, indicating that
the host closed the receive channel. If host does not close the receive channel use a timeout and progress to step 3.
3.
Delete the socket instance. If step 2 timed out, RST-flag will be sent to terminate the socket.
Application initiates shutdown:
1.
Receive data on socket, if zero bytes received it indicates that the host closed the receive channel of the
socket.
2.
Try to send any unsent data to the host.
3.
Send shutdown with CmdExt[1] set to 01h. This will send FIN-flag to host shutting down the receive
channel.
4.
Delete the socket instance.

For SOCK_STREAM-sockets, this command attempts to establish a connection to a host.
SOCK_STREAM-sockets may connect successfully only once, while SOCK_DGRAM-sockets may use this
service multiple times to change their association. SOCK-DGRAM-sockets may dissolve their association by
connecting to IP address 0.0.0.0, port 0 (zero).

Description
This command receives data from a connected socket. Message segmentation may be used to receive up to
1472 bytes (for more information, see Message Segmentation, p. 80).
For SOCK-DGRAM-sockets, the module will return the requested amount of data from the next received datagram. If the datagram is smaller than requested, the entire datagram will be returned in the response message. If the datagram is larger than requested, the excess bytes will be discarded.
For SOCK_STREAM-sockets, the module will return the requested number of bytes from the received data
stream. If the actual data size is less than requested, all available data will be returned.
NON-BLOCKING mode:
If no data is available on the socket, the error code 0006h (EWOULDBLOCK) will be returned.
BLOCKING mode:
The module will not issue a response until the operation has finished.
If the module responds successfully with 0 (zero) bytes of data, it means that the host has closed the connection. The send channel may however still be valid and must be closed using Shutdown and/or Delete.

Message Segmentation
General
Category: Extended
The maximum message size supported by the Anybus CompactCom 40 is normally 1524 bytes. In some applications a maximum message size of 255 bytes is supported, e.g. if an Anybus CompactCom 40 is to replace an Anybus CompactCom 30 without any changes to the application. The maximum socket message
size is 1472. To ensure support for socket interface messages larger than 255 bytes a segmentation protocol
is used.
The segmentation bits have to be set for all socket interface messages, in the commands where segmentation
can be used, whether the messages have to be segmented or not.
The segmentation protocol is implemented in the message layer and must not be confused with the fragmentation protocol used on the serial host interface. Consult the general Anybus CompactCom 40 Software
Design Guide for further information.
The module supports 1 (one) segmented message per instance
Command Segmentation
When a command message is segmented, the command initiator sends the same command header multiple
times. For each message, the data field is exchanged with the next data segment.
Command segmentation is used for the following commands (Socket Interface Object specific commands):
•
Send
•
Send To
When issuing a segmented command, the following rules apply:
•
When issuing the first segment, FS must be set.
•
When issuing subsequent segments, both FS and LS must be cleared.
•
When issuing the last segment, the LF-bit must be set.
•
For single segment commands (i.e. size less or equal to the message channel size), both FS and LS
must be set.
•
The last response message contains the actual result of the operation.
•
The command initiator may at any time abort the operation by issuing a message with AB set.
•
If a segmentation error is detected during transmission, an error message is returned, and the current
segmentation message is discarded. Note however that this only applies to the current segment; previously transmitted segments are still valid.

Response Segmentation
When a response is segmented, the command initiator requests the next segment by sending the same command multiple times. For each response, the data field is exchanged with the next data segment.
Response segmentation is used for responses to the following commands (Socket Interface Object specific
commands):
•
Receive
•
Receive From
When receiving a segmented response, the following rules apply:
•
In the first segment, FS is set.
•
In all subsequent segment, both FS and LS are cleared.
•
In the last segment, LS is set.
•
For single segment responses (i.e. size less or equal to the message channel size), both FS and LS are
set.
•
The command initiator may at any time abort the operation by issuing a message with AB set.

DHCP Option 61 (Client Identifier)
The DHCP Option 61 (Client Identifier) allow the end-user to specify a unique identifier, which has to be
unique within the DHCP domain.
Attribute #22 (DHCP Option 61 source) is used to configure the source of the Client Identifier. The table below
shows the definition for the Client identifier for different sources and their description.

Host Name
The MACID will be used as the Client Identifier
The configured Host Name will be used as the Client Identifier

Generic String
Attribute #23 will be used as the Client Identifier
Attribute #23 (DHCP Option 61 generic string) is used to set the Client Identifer when Attribute #22 has been
set to 3 (Generic String). Attribute #23 contains the Type field and Client Identifier and shall comply with the
definitions in RFC 2132. The allowed max length that can be passed to the module via attribute #23 is 64
octets.
Example:
If Attribute #22 has been set to 3 (Generic String) and Attribute #23 contains 0x01, 0x00, 0x30, 0x11, 0x33,
0x44, 0x55, the Client Identifier will be represented as an Ethernet Media Type with MACID
00:30:11:33:44:55.
Example 2:
If Attribute #22 has been set to 2 (Host Name) Attribute #23 will be ignored and the Client Identifier will be the
same as the configured Host Name.

Appendix A: Categorization of Functionality
A
95 (104)
Categorization of Functionality
The objects, including attributes and services, of the Anybus CompactCom and the application
are divided into two categories: basic 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.
Some of the functionality offered may be specialized and/or seldom used. As most of the available network functionality is enabled and accessible, access to the specification of the industrial
network may be required.

ERROR
The module stays in this state as long as it is
running. From here it can only change to ERROR or EXCEPTION.
Duplicate IP address detected
PROCESS_ACTIVE
-
IDLE
EXCEPTION
Unexpected error, e.g. watchdog timeout etc.
Comment
-
The module shall never enter any of
these states.
MS LED turns red (to indicate a major
fault)
NS LED is off
Application Watchdog Timeout Handling
Upon detection of an application watchdog timeout, the module will cease network participation
and shift to state ‘EXCEPTION’. No other network specific actions are performed.

Secure HICP (Secure Host IP Configuration
Protocol)
C.1
General
The Anybus CompactCom 40 Common Ethernet supports the Secure HICP protocol used by
the Anybus IPconfig utility for changing settings, e.g. IP address, Subnet mask, and enable/disable DHCP. Anybus IPconfig can be downloaded free of charge from the HMS website, www.
anybus.com. This utility may be used to access the network settings of any Anybus product
connected to the network via UDP port 3250.
The protocol offers secure authentication and the ability to restart/reboot the device(s).
C.2
Operation
When the application is started, the network is automatically scanned for Anybus products. The
network can be rescanned at any time by clicking Scan.
To alter the network settings of a module, double-click on its entry in the list. A window will appear, containing the settings for the module.
Fig. 8
Validate the new settings by clicking Set, or click Cancel to cancel all changes. Optionally, the
configuration can be protected from unauthorized access by a password. To enter a password,
check the Change password checkbox and enter the password in the New password text
field.
