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 SERCOS III networks.
2.2 Fieldbus Conformance Notes
•
The Anybus CompactCom 30 SERCOS III has been pre-compliance tested by the Institute for
Control Engineering of Machine Tools and Manufacturing Units (ISW) at the University of
Stuttgart and found to comply with SERCOS interface specification, Compliance Class A. For
details, please consult www.anybus.com.
For further information, please contact HMS.
2.3 Conformance Test Guide
When using the default settings of all parameters, the Anybus CompactCom SERCOS III 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 SDDML file, supplied by HMS, will require a certification. A Vendor ID can be obtained from SERCOS International and is compulsory for certification. This section
provides a guide for successful conformance testing your product, containing the Anybus CompactCom
SERCOS III module, to comply with the demands for network certification set by SERCOS International..
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.

2.3.2 Factory Default Reset
Reset command to Application Object (FFh) must be supported
When Anybus CompactCom 30 SERCOS III 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 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 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 to support the Anybus CompactCom
30 SERCOS III, however due to the nature of the SERCOS III networking system certain things must
be taken into account:
•
The Anybus CompactCom 30 SERCOS III supports one consuming and one producing connection.
•
The flexible nature of the Anybus concept allows the application to modify the behavior on SERCOS III in ways which contradict the generic SDDML File or in other ways voids network certification. Those responsible for the implementation of the final product should ensure that their
level of implementation matches their own requirements and policies regarding network certification and interoperability.
•
The use of advanced SERCOS III-specific functionality may require in-depth knowledge in
SERCOS III networking internals and/or information from the official SERCOS III specification. In such cases, the people responsible for the implementation of this product is expected
either to obtain these specifications to gain sufficient knowledge or limit their implementation in
such a way that this is not necessary.

Anybus-CompactCom Software Design Guide, ‘Application Data Object (FEh)’
3.1.2 SDDML File
Each device on SERCOS III is associated with an SDDML File in XML format, which holds a description of the device and its functions.
HMS supplies a generic Device Description File which can serve as a basis for new implementations.
However, due to the flexible nature of the Anybus CompactCom concept, it is possible to alter the functionality of the module in ways which contradicts the information in this file. This may cause trouble if
the master expects the configuration stated in the file. In some cases, these problems can be rectified by
the end user by manually changing I/O parameters etc. However, to ensure interoperability and to reduce the complexity for the end user, it is generally recommended to create a custom SDDML File to
match the final implementation of the product.
The following scenarios are known to require a custom SDDML File.
•
The use of a custom Vendor code
•
The use of a custom Vendor device ID
Note that any deviations from the generic SDDML File requires the use of custom Vendor- and Product
IDs.

Basic Operation 13
3.2 Network Identity
By default, the module identifies itself as a generic Anybus implementation as follows:
Vendor Code
Device Type
Vendor Device ID
Device Name
005Ah (HMS Industrial Networks, allocated by SERCOS International)
“Communication adapter”
“ABCC SRC3”
“Anybus-CompactCom SERCOS III”
It is possible to customize the identity information so that the Anybus module appears as a vendor specific implementation rather than a generic Anybus product. Note however that this invalidates the standard XML-file an thus re-certification of the product is necessary.

•
“SERCOS III Object (F1h)” on page 94
3.3 Communication Settings
Network related communication settings are grouped in the Network Configuration Object (04h). In
case of the Anybus CompactCom 30 SERCOS III this includes...
•
Ethernet Interface Settings
The module is locked to 100Mbit full duplex operation as required by SERCOS III.
•
TCP/IP Settings
These settings must be set in order for the module to be able to participate on the network.
•
SMTP Account Settings
These settings must be set in order for the module to be able to send email messages.

3.4 Network Data Exchange
3.4.1 Application Data (ADI)
Application Data Instances (ADIs) can be accessed from the network as manufacturer specific IDNs.
4096 ADIs are accessible in each of the eight manufacturer specific parameter sets, for a total of 32767
possible ADIs. However, SERCOS limits the maximum total number of IDNs in a slave to 16383. This
includes both standard IDNs and manufacturer specific IDNs. Any ADIs with instance numbers exceeding 32767 or order numbers exceeding 16383 minus the number of standard IDNs, implemented
by the module, will not be accessible.

Doc.Rev. 2.10
Doc.Id. HMSI-168-72
Basic Operation 14
3.4.2 Process Data
ADIs mapped as Process Data will be exchanged cyclically. The actual map is based on the Process Data
map specified during startup and cannot be changed from the network during runtime.
The module supports one consuming and one producing connection, each containing up to 256 bytes
of data as shown in this table:
Device control
2 Byte
Connection control
2 Byte
Process data connection content
IO Control
ABCC process data
2 Byte
0 - 256 Byte
Pad byte
0 - 1 Byte
If the process data size is not even (odd number of bytes), an extra pad byte is appended at the end.
Note 1: Due to limitations in the SERCOS FSP_IO profile, only a total of 255 process data mappings
(total of inputs and outputs) are supported.
Note 2: “Device control” is sent with “Process data connection”, but is not tied to it. The order does
not have to be as shown in the table.

“Manufacturer Specific IDNs” on page 20
3.5 Diagnostics
The standard Diagnostic Object (02h) provides access to basic diagnostic functionality. Major unrecoverable events will cause the module to physically disconnect itself from the network, thus preventing network participation.
Major diagnostic events are translated to SERCOS Class 1 diagnostic events, if support for latching diagnostic events is included in the SERCOS III application object. Otherwise the major diagnostic events
will be translated to class 2 events.
Up to 5 diagnostic instances can be created by the host application. An additional 6th instance may be
created in event of a major unrecoverable fault.

3.6 Web Interface
The built-in web server can be used to provide rich, dynamic content, by means of SSI scripting. This
enables access to information and configuration settings within the file system, as well as through the
Anybus CompactCom object module.
Web server content resides within the FLASH-based file system, which means it can be accessed and
customized as needed using a standard FTP-client.

3.7 Email Client
The built-in email client enables the host application to send email messages stored in the file system, or
defined directly within the SMTP Client Object (09h). Messages are scanned for SSI content, which
means it’s possible to embed dynamic information from the file system or from the Anybus CompactCom object model.

3.8 Network Reset Handling
3.8.1 Restore Manufacturer Parameters to Default
Upon receiving a ‘Load defaults procedure command’ from the network, the module will issue a reset
command to the Network Configuration Object (04h),with CmdExt[1] set to 01h (‘Factory default reset’).

•
“Command Details: Reset_Command” on page 57
3.9 SERCOS address
The SERCOS address range is 0 - 511. If defined during setup, the address can not be changed later
from the network. If defined after setup, the SERCOS address can be changed from the network.

3.10 File System
3.10.1 General Information
The built-in file system hosts 1.18 MByte of non-volatile storage, which can be accessed by the HTTP,
FTP and TFTP servers, the email client, and the host application.
The file system uses the following conventions:
•
‘\’ (backslash) is used as a path separator
•
A ‘path’ originates from the system root and as such must begin with a ‘\’
•
A ‘path’ must not end with a ‘\’
•
Names may contain spaces (‘ ’) but must not begin or end with one.
•
Names must not contain one of the following characters: ‘\ / : * ? “ < > |’
•
Names cannot be longer than 48 characters
•
A path cannot be longer than 255 characters (filename included)

•
“Email Client” on page 28
•
“Server Side Include (SSI)” on page 29
•
“File System Interface Object (0Ah)” on page 80
IMPORTANT: 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:
•
Deleting, moving or renaming a file or directory
•
Writing or appending data to an existing file
•
Formatting the file system
3.10.2 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:
[Key1]
value of Key1
[Key2]

List of FSP_IO function group replacements.
The module only supports one-to-one replacements.
Function groups 1502, 1503, 1504, and 1505 are supported.
Attempts at replacement with other function groups will be refused.
Procedure command used to perform the replacement according to
IDN/S-0-1500.0.11
One 1502 IDN is generated for every read process data mapping,
and one 1503 IDN is generated for every write process data mapping. Quantity and width are set to match the number of elements
and data type size of the mapping.
The structure instance number starts at 1 and is incremented for
each process data mapping. For this reason the module will only
support a maximum of 255 process data mappings.
Normally there are no 1504 or 1505 IDNs available, but IDN/S-01500.0.11 and procedure command IDN/S-0-1500.0.12 can be used
to replace digital 1502 and 1503 IDNs with analog 1504 and 1505
IDNs respectively.
The replacement is purely a change in representation of the process
data, and has no effect on the actual raw process data exchange.

5. FTP Server
5.1 General Information
The built-in FTP-server1 makes it easy to manage the file system using a standard FTP client.
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 8 concurrent connections.
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:Homedir1
User2:Password2:Homedir2
User3:Password3:Homedir3
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:Homedir1
User2:Password2:Homedir2
\path\userlistA:HomedirA
\path\userlistB:HomedirB
The files containing the user lists shall have the following format:
File Format:
User1:Password1
User2:Password2
User3:Password3
Notes:
•
Usernames must not exceed 15 characters in length.
•
Passwords must not exceed 15 characters in length.
•
Usernames and passwords must only contain alphabetic characters and/or numbers.
•
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 they should be able to log in,
just adding the user information to the 'ftp.cfg' file it is not enough.
1. The module also supports TFTP.

Doc.Rev. 2.10
Doc.Id. HMSI-168-72
FTP Server 23
•
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).
•
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’).
5.3 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 by right-clicking on the ‘Start’-button and selecting ‘Explorer’
2. In the address field, type FTP://<user>:<password>@<address>
- Substitute <address> with the IP address of the Anybus module
- Substitute <user> with the username
- Substitute <password> with the password
3. 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.

6. Web Server
6.1 General Information
The built-in web server provides a flexible environment for end-user interaction and configuration purposes. The powerful combination of SSI and client-side scripting allows access to objects and file system
data, enabling the creation of advanced graphical user interfaces.
The web interfaces 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 20 concurrent connections and communicates through port 80.

“FTP Server” on page 22
•
“Server Side Include (SSI)” on page 29
•
“Ethernet Host Object (F9h)” on page 97
6.2 Default Web Pages
The default web interface consists of a set of virtual files; these virtual files may be replaced, but not
permanently erased, by placing files with the same name in the same location (i.e. the web root).
The files can be used as-is or called
from a customized web environment.
index.htm
The files are:
<WebRoot>\style.css
<WebRoot>\arrow_red.gif
<WebRoot>\index.htm
<WebRoot>\netinfo.htm
<WebRoot>\netconfig.htm
<WebRoot>\netstat.htm
<WebRoot>\parameter.htm
<WebRoot>\language.htm
language.htm
parameter.htm
netinfo.htm
netconfig.htm
netstat.htm
Note: If none of these files are used, it is recommended to completely disable the virtual file system
altogether in the File System Interface Object.

SSI File Types
By default, only files with the extension ‘shtm’ are
scanned for SSI. Additional SSI file types can be
added here as necessary.
The web root directory determines the location of all files related to the web interface. Files outside of
this directory and its sub-directories cannot be accessed by the web server.
6.3.2 Index Page
The module searches for possible index pages in the following order:
1. <WebRoot>\index.htm
2. <WebRoot>\index.html
3. <WebRoot>\index.shtm
4. <WebRoot>\index.wml
Note 1: Substitute <WebRoot> with the web root directory specified in ‘\http.cfg’.
Note 2: If no index page is found, the module will default to the virtual index file (if enabled).

7. Email Client
7.1 General Information
The built-in email client allows the application to send email messages through an SMTP-server. Messages can either be specified directly in the SMTP Client Object, 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.
See also...
•
“Network Configuration Object (04h)” on page 51
•
“SMTP Client Object (09h)” on page 75
7.2 How to Send Email Messages
To be able to send email messages, the SMTP-account settings must be specified.
This includes...
•
A valid SMTP-server address
•
A valid user name
•
A valid password
To send an email message, perform the following steps:
1. Create a new email instance using the ‘Create’-command (03h)
2. Specify the sender, recipient, topic and message body in the email instance
3. Issue the ‘Send Instance Email’-command (10h) towards the email instance
4. Optionally, delete the email 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. For a description of the file format, see “Command Details: Send Email From File” on page 78.

8.3.9 printf()
This function returns a formatted string which may contain data from the Anybus 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.

8.3.10 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.
Note: This command cannot be used in email messages.

Comments
Optionally, it is possible to exchange the BOOL data with a message
based on the value (true or false). In such case, the actual data type
returned from the function will be STRING.
Syntax: BOOL<true><false>
For arrays, the format will be BOOL[n]<true><false>.
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
IMPORTANT: 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.

(no data)
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 (EDESTADDRREQ (14)) 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.
Host 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.

Description
This command accepts incoming connections on a listening TCP socket. A new socket instance is created for each accepted connection. The new socket is connected with the host and the response returns
its instance number.
NON-BLOCKING mode:
This command must be issued repeatedly (polled) for incoming connections. If no incoming
connection request exists, the module will respond with error code 0006h (EWOULDBLOCK).
BLOCKING mode:
This command will block until a connection request has been detected.
Note: This command will only be accepted if there is a free instance to use for accepted connections.
For blocking connections, this command will reserve an instance.

Command Code.:

Valid for:

Description
For SOCK-DGRAM-sockets, this command specifies the peer with which the socket is to be associated
(to which datagrams are sent and the only address from which datagrams are received).
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).
NON-BLOCKING mode:
This command must be issued repeatedly (polled) until a connection is connected, rejected or
timed out. The first connect-attempt will be accepted, thereafter the command will return error
code 22 (EINPROGRESS) on poll requests while attempting to connect.
BLOCKING mode:
This command will block until a connection has been established or the connection request is
cancelled due to a timeout or a connection error.

Command Code.:
15h
Valid for:
Instance
Description
This command receives data from a connected socket. Message segmentation may be used to receive up
to 1472 bytes (see “Message Segmentation” on page 102).
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:
If no data is available, the command will block until there is.
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’.

10.2 SERCOS III Object (F1h)
Category
Basic, extended
Object Description
This object implements SERCOS specific features in the host application.
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]”).
Note that some of the commands used when accessing this object may require segmentation. For more
information, see “Message Segmentation” on page 102.

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 SUP-Bit Definition
The supervised bit (SUP) indicates that the network participation is supervised by another network device. In the case of SERCOS III, this bit is set when the SERCOS III slave state machine is in “operating
level”, meaning state is CP2 .. CP4 and “operation state outputs” bit in IO Control word is set.
B.2 Anybus State Machine

Appendix C
C. Message Segmentation
C.1 General
The maximum message size supported by the Anybus-CompactCom is 255 bytes. To provide support
for longer messages (needed when using the socket interface), a segmentation protocol is used.
The segmentation protocol is implemented in the message layer and must not be confused with the fragmentation used on the serial host interface. Consult the general Anybus-CompactCom Software Design
Guide for further information.
The module supports 1 (one) simultaneous segmented message per instance.
C.2 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:
•
Send (see “Command Details: Send” on page 69)
•
Send To (see “Command Details: Send_To” on page 70)
Segmentation Control bits (Command)
Bit

Set if the current segment is the last segment
Set if the segmentation shall be aborted
Set to 0 (zero).
Segmentation Control bits (Response)
Bit
0...7
Contents
(reserved)
Meaning
Ignore.
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 255 bytes), 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.

Message Segmentation 103
C.3 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:
•
Receive (object specific, see “Command Details: Receive” on page 67)
•
Receive From (object specific, see “Command Details: Receive_From” on page 68)

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 255 bytes), both FS and LS are set.
•
The command initiator may at any time abort the operation by issuing a message with AB set.

Appendix D
D. HICP (Anybus IPconfig)
D.1 General
The module supports the HICP protocol used by the Anybus IPconfig utility, which can be downloaded
free of charge from the HMS website. This utility may be used to access the network settings of any Anybus product connected to the network via UDP port 3250.
D.2 Operation
Upon starting the program, the network is scanned for Anybus products. The network can be rescanned at any time by clicking ‘Scan’.
To alter the network settings of the module, doubleclick on its entry in the list. A window will appear,
containing the settings for the module.
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, click on the ‘Change password’ checkbox, and
enter the password under ‘New password’.
