Chapter 2
2. Basic Operation
2.1 General
The Anybus Communicator is designed to exchange data between a serial sub-network and a higher level
network. Unlike most other similar devices, the Anybus Communicator has no fixed protocol for the
sub-network, and consequently can be configured to handle almost any form of serial communication.
The gateway can issue serial telegrams cyclically, on change of state, or based on trigger events issued by
the control system in the higher level network (i.e. the fieldbus master or PLC). It can also monitor certain aspects of the sub-network communication and notify the higher level network when data has
changed.
An essential part of the Anybus Communicator package is Anybus Configuration Manager (ACM), a
Windows-based application used to supply the gateway with a description of the sub-network protocol.
No programming skills are required; instead, a visual protocol description-system is used to specify the
different parts of the serial communication.

Basic Operation 17
2.2 Data Exchange Model
Internally, data exchanged on the sub-network and on
the higher level network all resides in the same memory.
ABC Internal Memory
This means that in order to exchange data with the subnetwork, the higher level network simply reads and
writes data to the memory locations specified using the
Anybus Configuration Manager. The very same memory locations can then be exchanged on the sub-network.
Input Data (512 bytes)
Higher Level Network
•
Output Data
(512 bytes)
Subnetwork
The internal memory buffer is divided into three areas,
based on function:
Input Data
(512 bytes)
This area can be read by the higher level network, the web server and the E-mail client.
(Data representation on the higher level network is described later in this chapter).
•
General Data
Output Data (512 bytes)
This area can be read/written to by the higher
level network, the web server and the E-mail client.
(Data representation on the higher level network is described later in this chapter).
•
General Data (up to 1024 bytes)
This area cannot be accessed from the higher level network, but can be used for transfers
between individual nodes on the sub-network, or as a general “scratch pad” for data. The actual
size of this area depends on the amount of data that is exchanged on the sub-network. The gateway can handle up to 1024 bytes of general data.
2.2.1 Memory Map
When building the sub-network configuration using the Anybus Configuration Manager, the different

2.2.2 Data Exchange Example
In the following example, a temperature regulator on the sub-network exchanges information with a
PLC on the higher level network, via the internal memory buffers in the Anybus Communicator.
PLC (EtherNet/IP Scanner)
PLC Memory (Inputs)
PLC Memory (Outputs)
Actual Temperature
Temperature Setpoint
EtherNet/IP
The PLC Memory associated with
the ABC is exchanged;
Data from the Input Data area is copied to
PLC Input Memory, and PLC Output
Memory is copied to the Output Data
area.
The PLC exchange data between the internal
PLC memory and the slaves (in this case the
ABC) on the EtherNet/IP network.

Basic Operation 19
2.3 Sub-network Protocol
2.3.1 Protocol Modes
The Anybus Communicator features three distinct operating modes for sub-network communication:
‘Master Mode’, ‘DF1 Master Mode’ and ‘Generic Data Mode’. Note that the protocol mode only specifies the basic communication model, not the actual sub-network protocol.
•
Master Mode
In this mode, the gateway acts as a master on the sub-network, and the serial communication is
query-response based. The nodes on the network are not permitted to issue messages unless first
addressed by the gateway .
For more information about this mode, see “Master Mode” on page 20.
•
DF1 Master Mode
In this mode, the gateway acts as a master on the sub-network, using the DF1 protocol. The serial
communication is query-response based. For more information about this mode, see “DF1 Protocol Mode” on page 86.
•
Generic Data Mode
In this mode, there is no master-slave relationship between the sub-network nodes and the gateway; any node on the sub-network, including the gateway, may spontaneously produce or consume messages.
For more information about this mode, see “Generic Data Mode” on page 21.
2.3.2 Protocol Building Blocks
The following building blocks are used in Anybus Configuration Manager to describe the sub-network
communication. How these blocks apply to the three protocol modes is described later in this document.
•
Node
A ‘node’ represents a single device on the sub-network. Each node can be associated with a number of transactions, see below.
•
Transaction
A ‘transaction’ represents a complete serial telegram, and consists of a number of frame objects
(see below). Each transaction is associated with a set of parameters controlling how and when to
use it on the sub-network.
•
Commands
A ‘command’ is simply a predefined transaction stored in a list in the Anybus Configuration Manager. This simplifies common operations by allowing transactions to be stored and reused.
•
Frame Object
‘Frame objects’ are low level entities used to compose a transaction (see above). A frame object
can represent a fixed value (a constant), a range of values (limit objects), a block of data or a calculated checksum.
Anybus Communicator EtherNet/IP/Modbus-TCP 2-port User Manual
Doc: HMSI-27-316, Rev. 1.00
Basic Operation 20
2.3.3 Master Mode
In this mode, the communication is based on a query-response scheme; when the gateway issues a query
on the sub-network, the addressed node is expected to issue a response. Nodes are not permitted to issue
responses/messages spontaneously, i.e. without first receiving a query.
There is, however, one exception to this rule; the broadcaster. Most protocols offer some way of broadcasting messages to all nodes on the network, without expecting them to respond to the broadcasted
message. This is also reflected in the gateway, which features a dedicated broadcaster node.
Control System
Gateway
Subnetwork Devices
In Master Mode, Anybus Configuration Manager comes pre-loaded with the most commonly used
Modbus RTU commands, which can be conveniently reached by right-clicking on a node in the Anybus
Configuration Manager and selecting ‘Insert New Command’. Note, however, that this in no way
prevents other protocols based on the same query-response message-scheme from also being implemented.
Anybus Communicator EtherNet/IP/Modbus-TCP 2-port User Manual
Doc: HMSI-27-316, Rev. 1.00
Basic Operation 21
2.3.4 Generic Data Mode
In this mode, there is no master-slave relationship between the nodes on the sub-network and the gateway. Any node (including the gateway) may spontaneously produce or consume a message. Nodes are
not obliged to respond to messages, nor do they need to wait for a query in order to send a message.
Control System
Gateway
Subnetwork Devices
In the figure above, the Anybus Communicator ‘consumes’ data ‘produced’ by a node on the sub-network. 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
sub-network, for ‘consumtion’ by a node.
2.3.5 DF1 Master Mode
Please refer to “DF1 Protocol Mode” on page 86.

Basic Operation 22
2.4 EtherNet/IP
2.4.1 General
EtherNet/IP is based on the Control and Information Protocol (CIP), which is also the application layer
for DeviceNet and ControlNet. The Anybus Communicator acts as a Group 2 or 3 server on the
EtherNet/IP network.
Input and output data is accessed using I/O connections or explicit messages towards the assembly object and the parameter input/output mapping objects.
Note: The EtherNet/IP Run/Idle header function must be disabled in the Anybus Configuration Manager if explicit messaging is used.
See also...
•
“CIP Object Implementation” on page 107
•
“Fieldbus Settings” on page 63
2.4.2 Data Types
The input and output data hold two types of data; I/O data and parameter data. I/O data is exchanged
on change of value, and can be accessed using I/O connections towards the assembly object.
Parameter data can be accessed acyclically via the parameter input and output mapping objects. Note,
however, that each instance attribute within these objects must be created manually using the Anybus
Configuration Manager.
For more information see “Parameter Data Initialization (Explicit Data)” on page 121.

2.5 Modbus-TCP
2.5.1 General
The Modbus-TCP protocol is an implementation of the standard Modbus protocol running on top of
TCP/IP. The built-in Modbus-TCP server provides access to the input and output data areas via a subset of the functions defined in the Modbus-TCP specification.
The server supports up to 8 simultaneous connections and communicates over TCP port 502. For detailed information regarding the Modbus-TCP protocol, consult the Open Modbus Specification.
2.5.2 Addressing Modes
The Anybus Communicator features two different modes of operation regarding the Modbus communication:
•
Modbus Addressing Mode (Default)
In this mode, the input and output data areas are mapped to different function codes.
Note that coil addressing is not possible in this mode.
See also...
- “Modbus Addressing Mode” on page 25
•
Anybus Addressing Mode
Compared to Modbus Addressing Mode, this mode allows data to be addressed in a more flexible
way. Note however that several function codes can be used to access the same data in the gateway. While this may appear confusing at first, it allows data to be manipulated in ways not possible in Modbus Addressing Mode (e.g. it is possible to manipulate individual bits of a register by
accessing coils associated with the same memory location).

3. File System
3.1 General
General
The Anybus Communicator features a built-in file system, which is used to store information such as
web files, network communication settings, e-mail messages etc.
Storage Areas
The file system consists of the different storage areas:
•
Non-volatile area (approx. 1.4 Mb)
This section is intended for static files such as web files, configurations files etc.
•
Volatile area (approx. 1 Mb)
This area is intended for temporary storage; data placed here will be lost in case of power loss or
reset.
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 may not contain the following characters: ‘\ / : * ? “ < > |’
•
Names cannot be longer than 48 characters (plus null termination)
•
A path cannot be longer than 256 characters (filename included)
•
The maximum number of simultaneously open files is 40
•
The maximum number of simultaneously open directories is 40
Important Note:
The non-volatile storage is located in FLASH memory. Each FLASH segment can be erased approximately 100 000 times.
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

3.3 System Files
The file system contains a set of files used for system configuration. These files, known as “system files”,
are regular ASCII files that can be altered using a standard text editor (such as the Notepad in Microsoft
Windows™). Note that some of these files may also be altered by the gateway itself, e.g. when using SSI
(see “Server Side Include (SSI)” on page 44).
The format of the system files are based on the concept of ‘keys’, where each ‘key’ can be assigned a
value, see example below.
Example:
[Key1]
value of key1
[Key2]
value of key2
The exact format of each system file is described in detail later in this document.
The contents of the above files can be redirected:
Example:
In this example, the contents will be loaded from the file ‘here.cfg’.
[file path]
\i\put\it\over\here.cfg
Note: Any directory in the file system can be protected from web access by placing the file web-accs.cfg
in the directory, see “Authorization” on page 42.

4. FTP Server
4.1 General
The built-in FTP server provides a way to access the file system using a standard FTP client.
The following port numbers are used for FTP communication:
•
TCP, port 20 (FTP data port)
•
TCP, port 21 (FTP command port)
Security Levels
The FTP server features two security levels; admin and normal.
•
Normal level users
The root directory will be ‘\user’.
•
Admin level users
The root directory will be ‘\’, i.e. the user has unrestricted access to the file system.
User Accounts
The user accounts are stored in two files, which are protected from web access:
•
‘\user\pswd\sys_pswd.cfg’
This file holds the user accounts for normal level users.
•
‘\pswd\ad_pswd.cfg’
This file holds the user accounts for admin level users.
File Format:
The format of these files are as follows:
Username1:Password1
Username2:Password2
Username3:Password3
Note 1: If no valid user accounts have been defined, the gateway will grant admin level access to all users. In such cases, the FTP accepts any username/password combination, and the root directory will be
‘\’.
Note 2: The FTP server shares user accounts with the Telnet server.

FTP Server 30
4.2 FTP Connection Example (Windows Explorer)
The built-in FTP client in Windows Explorer 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 ‘Explore’.
2. In the address field, type FTP://<user>:<password>@<address>
- Substitute <address> with the IP address of the Anybus Communicator
- Substitute <user> with the username
- Substitute <password> with the password
3. Press enter. The Explorer will now attempt to connect to the gateway using the specified settings.
If successful, the built in file system is displayed in the Explorer window.

5. Telnet Server
5.1 General
The built-in Telnet server provides a way to access the file system using a standard Telnet client. The
server communicates through TCP port 23.
Security Levels
Just like the FTP server, the Telnet server features two security levels; admin and normal.
•
Normal level users
The root directory will be ‘\user’.
•
Admin level users
The root directory will be ‘\’, i.e. the user has unrestricted access to the file system.
User Accounts
The Telnet server shares user accounts with the FTP server. If no valid user accounts have been defined,
the gateway will grant admin level access to all users. In such case, no login is required, and the root directory will be ‘\’.

6. Basic Network Configuration
6.1 General Information
The Anybus Communicator offers two modes of operation regarding the network settings:
•
Settings specified in Anybus Configuration Manager
When valid settings have been specified in Anybus Configuration Manager
(‘TCP/IP Settings’ = enabled), then these are the settings the gateway will use.
When settings have been specified in Anybus Configuration Manager, the contents of the system
file ‘ethcfg.cfg’ will be ignored completely, causing the following behavior:
- DNS services will not be available
- Domain and Host name cannot be set
- E-mail services will not be available
- Network settings received via HICP or DCP) will be lost in the event of a power loss or a
reset.
•
Settings specified in ‘ethcfg.cfg’
If no settings are specified in Anybus Configuration Manager (i.e. ‘TCP/IP Settings’ = disabled),
the gateway will use the settings stored in the system file ‘ethcfg.cfg’.
If this file is missing, the gateway will attempt to retrieve the settings via DHCP or HICP for 30
seconds. If no configuration has been received within this period, the gateway will halt and indicate an error on the on-board LEDs.
EtherNet/IP
The TCP/IP settings can be accessed from EtherNet/IP through the TCP/IP Interface Object.

“TCP/IP Interface Object, Class F5h” on page 117
DHCP/BootP
The Anybus Communicator can retrieve the TCP/IP settings from a DHCP or BootP server. If no
DHCP server is found, the gateway will default to the current settings in ‘\ethcfg.cfg’.
If no current settings are available (‘ethcfg.cfg’ is missing, or contains invalid settings), the gateway will
halt and indicate an error on the on-board status LEDs (the network configuration may however still be
accessed via HICP, see “Anybus IPconfig (HICP)” on page 40.

6.2 Ethernet Configuration File (‘ethcfg.cfg’)
6.2.1 General
To exist on the network, the Anybus Communicator needs a valid TCP/IP configuration. These settings
are stored in the system file ‘\ethcfg.cfg’. Note that if TCP/IP settings are enabled in Anybus Configuration Manager, then the IP address, gateway and subnet settings in ethcfg.cfg will be overwritten every
time the module is restarted. All other settings are unaffected.

6.5 Anybus IPconfig (HICP)
The Anybus Communicator supports the HICP protocol used by the Anybus IPconfig utility from
HMS, which can be downloaded free of charge from the HMS website. This utility may be used to configure the network settings of any Anybus product connected to the network. Note that if successful,
this will replace the settings currently stored in the configuration file (‘ethcfg.cfg’).
Upon starting the program, the network
is scanned for Anybus products. The network can be rescanned at any time by
clicking ‘Scan’. In the list of detected devices, the gateway will appear as ‘ABCEIP’. To alter its network settings, double-click on its entry in the list.
A window will appear, containing the IP
configuration and password settings.
Validate the new settings by clicking ‘Set’,
or click ‘Cancel’ to abort.
Optionally, the configuration may 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’. When protected, any changes in the configuration requires that the user supplies a valid password.
When done, click ‘Set’. The new IP configuration will now be stored in the configuration file (‘ethcfg.cfg’).
Note that if ‘TCP/IP Settings’ has been enabled in the Anybus Configuration Manager, any settings received via HICP will be lost in the event of a power loss or reset.

Protected Files
For security reasons, the following files are protected from web access:
•
Files located in ‘\user\pswdcfg\pswd’
•
Files located in ‘\pswd’
•
Files located in a directory which contains a file named ‘web_accs.cfg’
Default Web Pages
The Anybus Communicator contains a set of virtual files which can be used when building a web page
for configuration of network parameters. These virtual files can be overwritten (not erased) by placing
files with the same name in the root of disc 0.
This makes it possible to, for example, replace the HMS logo by uploading a new logo named ‘\logo.jpg’.
It is also possible to make links from a web page to the virtual configuration page. In such case the link
shall point to ‘\config.htm’.
These virtual files are:
\index.htm

8. Server Side Include (SSI)
General
Server Side Include (from now on referred to as SSI) functionality enables dynamic content to be used
on web pages and in e-mail messages.
SSI are special commands embedded in the source document. When the Anybus module encounters
such a command, it will execute it, and replace it with the result (when applicable).
Syntax
The ‘X’s below represents a command opcode and parameters associated with the command.
<?--#exec cmd_argument=’XXXXXXXXXXXXXXXXXXXXXX’-->
Example
The following example causes a web page to display the Ethernet Mac ID of the module:
<HTML>
<HEAD><TITLE>SSI Test</TITLE></HEAD>
<BODY>
The Ethernet Mac ID of the Anybus module is:
<?--#exec cmd_argument=’DisplayMacID’-->
</BODY>
</HTML>
Resulting webpage:
The Ethernet Mac ID of the ABC is: 00:30:11:78:9A:BC

GetText
Note: This function cannot be used in e-mail messages.
This SSI function gets the text from an object and stores it in the OUT area.
Syntax:
<?--#exec cmd_argument=’GetText( "ObjName", OutWriteString ( offset ), n )’-->
ObjName- Name of object.

printf
This SSI function includes a formatted string, which may contain data from the Anybus IN/OUT area,
on a web page. The formatting of the string is equal to the standard C function printf().
Syntax:
<?--#exec cmd_argument=’printf("String to write", Arg1, Arg2, ..., ArgN)’-->
Like the standard C function printf() the "String to write" for this SSI function contains two types of
objects: Ordinary characters, which are copied to the output stream, and conversion specifications, each
of which causes conversion and printing of the next successive argument to printf. Each conversion
specification begins with the character % and ends with a conversion character. Between the % and the
conversion character there may be, in order:
•
Flags (in any order), which modify the specification:
+
(space)
0
#
which specifies left adjustment of the converted argument in its field.
which specifies that the number will always be printed with a sign
if the first character is not a sign, a space will be prefixed.
for numeric conversions, specifies padding to the field with leading zeroes.
which specifies an alternate output form. For o, the first digit will be zero. For x or
X, 0x or 0X will be prefixed to a non-zero result. For e, E,f, g and G, the output
will always have a decimal point; for g and G, trailing zeros will not be removed.
•
A number specifying a minimum field width. The converted argument will be printed in a field
at least this wide, and wider if necessary. If the converted argument has fewer characters than the
field width it will be padded on the left (or right, if left adjustment has been requested) to make
up the field width. The padding character is normally space, but can be 0 if the zero padding flag
is present.
•
A period, which separates the field width from the precision.
•
A number, the precision, that specifies the maximum number of characters to be printed from a
string, or the number of digits to be printed after the decimal point for e, E, or F conversions,
or the number of significant digits for g or G conversion, or the minimum number of digits to
be printed for an integer (leading 0s will be added to make up the necessary width)
•
A length modifier h, l (letter ell), or L. "h" Indicates that the corresponding argument is to be
printed as a short or unsigned short; "l" indicates that the argument is along or unsigned long.

byte, short; decimal notation.
byte, short;single character, after conversion to unsigned char.
char*; characters from the string are printed until a "\0" is reached or until the number of characters
indicated by the precision have been printed
float; decimal notation of the form [-]mmm.ddd, where the number of d’s is specified by the precision. The default precision is 6; a precision of 0 suppresses the decimal point.
float; decimal notation of the form [-]m.dddddd e+-xx or[-]m.ddddddE+-xx, where the number of d’s
specified by the precision. The default precision is 6; a precision of 0 suppresses the decimal point.
float; %e or %E is used if the exponent is less than -4 or greater than or equal to the precision; otherwise %f is used. Trailing zeros and trailing decimal point are not printed.
no argument is converted; print a %

8.2 Changing SSI output
There are two methods of changing the output strings from SSI functions:
1. Changing SSI output defaults by creating a file called "\ssi_str.cfg" containing the output strings
for all SSI functions in the system.
2. Temporary changing the SSI output by calling the SSI function "SsiOutput()".
8.2.1 SSI Output String File
If the file "\ssi_str.cfg" is found in the filesystem and the file is correct according to the specification
below, the SSI functions will use the output strings specified in this file instead of the default strings.
The files shall have the following format:
[StoreEtnConfig]
Success: "String to use on success"
Invalid IP: "String to use when the IP address is invalid"
Invalid Subnet: "String to use when the Subnet mask is invalid"
Invalid Gateway: "String to use when the Gateway address is invalid"
Invalid Email server: "String to use when the SMTP address is invalid"
Invalid IP or Subnet: "String to use when the IP address and Subnet mask does
not match"
Invalid DNS1: "String to use when the primary DNS cannot be found"
Invalid DNS2: "String to use when the secondary DNS cannot be found"
Save Error: "String to use when storage fails"
Invalid DHCP state: "String to use when the DHCP state is invalid"
[scanf]
Success: "String to use on success"
Failure: "String to use on failure"
[IncludeFile]
Failure: "String to use when failure"1
[SaveToFile]
Success: "String to use on success"
Failure: "String to use on failure"1
[SaveDataToFile]
Success: “String to use on success”
Failure: “String to use on failure”1
[GetText]
Success: “String to use on success”
Failure: “String to use on failure”
The contents of this file can be redirected by placing the line ‘[File path]’ on the first row, and a file path
on the second.
Example:
[File path]
\user\ssi_strings.cfg
In this example, the settings described above will be loaded from the file ‘user\ssi_strings.cfg’.
1. ‘%s’ includes the filename in the string

8.2.2 Temporary SSI Output change
The SSI output for the next called SSI function can be changed with the SSI function “SsiOutput()”.
The next called SSI function will use the output according to this call. Thereafter the SSI functions will
use the default outputs or the outputs defined in the file ‘\ssi_str.cfg’. The maximum size of a string is
128 bytes.
Syntax:
<?--#exec cmd_argument=’SsiOutput( "Success string", "Failure string" )’-->
Example:
This example shows how to change the output strings for a scanf SSI call.
<?--#exec cmd_argument=’SsiOutput ( "Parameter1 updated", "Error" )’-->
<?--#exec cmd_argument="scanf( "Parameter1", "%d", OutWriteByte(0) )’-->

9. E-mail Client
9.1 General
The built-in e-mail client can send predefined e-mail messages based on trigger-events in input and output data areas. The client supports SSI, however note that some SSI functions cannot be used in e-mail
messages (specified separately for each SSI function).
See also...
•
“Server Side Include (SSI)” on page 44
Server Settings
The Anybus Communicator needs a valid SMTP server configuration in order to be able to send e-mail
messages. These settings are stored in the system file ‘\ethcfg.cfg’.
See also...
•
“Ethernet Configuration File (‘ethcfg.cfg’)” on page 37
Event-Triggered Messages
As mentioned previously, the e-mail client can send predefined messages based on events in the input
and output data areas. In operation, this works as follows:
1. The trigger source is fetched from a specified location
2. A logical AND is performed between the trigger source and a mask value
3. The result is compared to a reference value
4. If the result is true, the e-mail is sent to the specified recipient(s).
Which events that shall cause a particular message to be sent, is specified separately for each message.
For more information, see “E-mail Definitions” on page 57.
Note that the input and output data areas are scanned twice per second, i.e. to ensure that an event is
detected by the gateway, it must be present longer than 0.5 seconds.

9.2 E-mail Definitions
The e-mail definitions are stored in the following two directories:
•
‘\user\email’
This directory holds up to 10 messages which can be altered by normal level FTP users.
•
‘\email’
This directory holds up to 10 messages which can be altered by admin level FTP users.
E-mail definition files must be named ‘email_1.cfg’, ‘email_2.cfg’... ‘email_10.cfg’ in order to be properly
recognized by the gateway.

13. Transactions
13.1 General
As mentioned previously, transactions are representations of the actual serial telegrams exchanged on
the serial sub-network. Although the gateway does not feature a scan list in the traditional sense, all
nodes and their transactions will be processed in the order they were defined in ACM.
Transactions are handled slightly differently in the three protocol modes:
•
Master Mode
For regular nodes, transactions always come in pairs; a query and a response. The query is issued
by the gateway, while responses are issued by the slaves on the sub-network. The Broadcaster
can only send transactions.
•
Generic Data Mode
Transactions can be added as desired for both directions. Transactions sent to the sub-network
are called “Transaction Produce”, and transactions issued by other nodes are called “Transaction
Consume”.
•
DF1 Master Mode
Please refer to “DF1 Protocol Mode” on page 86.
Theoretically, the gateway supports up to 150 transactions. The actual number may however be less depending on the memory requirements of the defined transactions.

13.3 Transaction Parameters (Master Mode)
13.3.1 Parameters (Query & Broadcast)
Parameter
Minimum time between broadcasts (10 ms)
Description
This parameter specifies how long the gateway shall wait after transmitting a broadcast transaction before processing the next entry in the scanlist. The value should be
set high enough to allow the slave devices time to finish the handling of the broadcast.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
Offline options for fieldbus
Note: This setting is only relevant for the Broadcaster node.
This parameter specifies the action to take for this transaction if the higher level network goes offline. This affects the data that is sent to the sub-network.
• Clear - The data destined for the slave-devices is cleared (set to zero)
• Freeze - The data destined for the slave-device is frozen
Offline options for sub-network
• NoScanning -The updating of the sub-network is stopped
This parameter specifies the action to take for this transaction if the sub-network goes
offline. This affects the data that is reported to the control system.
• Clear - Data is cleared (0) on the higher level network if the sub-network goes
offline
Reconnect time (10 ms)
• Freeze - Data is frozen on the higher level network if the sub-network goes offline
This parameter specifies how long the gateway shall wait before attempting to reconnect a disconnected node. A node will be disconnected in case the maximum number
of retries (below) has been reached.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
Retries
Timeout time (10 ms)
Trigger byte address
Note: This setting is not relevant for the Broadcaster node.
This parameter specifies how many times a timeout may occur in sequence before the
node is disconnected.
This parameter specifies how long the gateway will wait for a response from a node. If
this time is exceeded, the gateway will retransmit the Query until the maximum number of retries (see above) has been reached.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
This parameter specifies the location of the trigger byte in internal memory (only relevant when “Update mode” is set to “Change of state on trigger”).
Valid settings range from 0x200 to 0x3FF and 0x400 to 0xFFF
Anybus Communicator EtherNet/IP/Modbus-TCP 2-port User Manual
Doc: HMSI-27-316, Rev. 1.00
Transactions 71
Parameter
Update mode
Description
This parameter is used to specify when the transaction shall be sent to the slave:
• Cyclically
The transaction is issued cyclically at the interval specified in the “Update time”
parameter.
• On data change
The data area is polled for changes at the time interval defined by Update time. A
transaction is issued when a change in data is detected.
• Single shot
The Query is issued once at start up.
• Change of state on trigger
Update time (10 ms)
The Query is issued when the trigger byte value has changed. This feature enables the control system to notify the gateway when to issue a particular Query. To
use this feature correctly, the control system must first update the data area associated with the Query/transaction, then increase the trigger byte by one. The location of the trigger byte is specified by the “Trigger byte address” parameter. The
trigger byte is checked at the interval specified in the “Update time” parameter.
This parameter specifies how often the transaction will be issued in steps of 10 ms
(relevant only when “Update mode” is set to “Cyclically”, “On data change” or “Change
of state on trigger”).
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
13.3.2 Parameters (Response)
Parameter
Trigger byte
Trigger byte address
Description
This parameter is used to enable/disable the trigger functionality for the response. If
enabled, the gateway will increase the trigger byte by one when the gateway receives new
data from the sub-network. This can be used to notify the control system of the updated
data.
The location of the trigger byte is specified by the “Trigger byte address” parameter below.
This parameter specifies the location of the trigger byte in the internal memory buffer.
Valid settings range from 0x000 to 0x1FF and 0x400 to 0xFFF

13.4 Transaction Parameters (Generic Data Mode)
13.4.1 Produce Transactions
Parameter
Offline options for fieldbus
Description
This parameter specifies the action to take for this transaction if the higher level network
goes offline. This affects the data that is sent to the sub-network.
• Clear
Data is cleared (0) on the sub-network if the higher level network goes offline
• Freeze
Data is frozen on the sub-network if the higher level network goes offline
• NoScanning
Update mode
Stop subnet scanning for this transaction if the higher level network goes offline
The update mode for the transaction:
• Cyclically
The transaction is sent cyclically at the interval specified in “Update Time”.
• On data change
The data area is polled for changes at the time interval defined by Update time.
A transaction is issued when a change in data is detected.
• Single shot
The transaction is sent once at startup.
• Change of state on trigger
Update time (10 ms)
The transaction is sent when the trigger byte has changed. This feature enables the
control system to notify the gateway when to issue a particular transaction. To use this
feature correctly, the control system must first update the data area associated with
the transaction, then increase the trigger byte by one. The location of the trigger byte
is specified by the “Trigger byte address” parameter. The trigger byte is checked at the
interval specified in the “Update time” parameter.
This parameter specifies how often the transaction will be issued in steps of 10ms
(relevant only when “Update mode” is set to “Cyclically”, “On data change” or “Change of
state on trigger”).
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.

Transactions 73
Parameter
Trigger byte address
Description
This parameter specifies location of the trigger byte in the internal memory buffer.
If “Update mode” is set to “Change of state on trigger”, the memory location specified by
this parameter is monitored by the gateway. Whenever the trigger byte is updated, the
gateway will produce the transaction on the sub-network.
This way, the control system can instruct the gateway to produce a specific transaction on
the sub-network by updating the corresponding trigger byte.
The trigger byte should be incremented by one for each activation. Please note that the
trigger byte address must be unique to each transaction. It can not be shared by two or
more transactions.
Note: This parameter has no effect unless the “Update mode” parameter is set to “Change
of state on trigger”.
Valid settings range from 0x200 to 0x3FF and 0x400 to 0xFFF
13.4.2 Consume Transactions
Parameter
Description
Offline options for sub-network This parameter specifies the action to take for this transaction if the sub-network goes
offline. This affects the data that is sent to the higher level network.
• Clear
Data is cleared (0) on the higher level network if the sub-network goes offline
• Freeze
Offline timeout time (10 ms)
Trigger byte
Data is frozen on the higher level network if the sub-network goes offline
This parameter specifies the maximum allowed time between two incoming messages
in steps of 10ms. If this time is exceeded, the sub-network is considered to be offline. A
value of 0 disables this feature, i.e. the sub-network can never go offline.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
• Enable
Enables the trigger byte. The location of the trigger byte must be specified in “Trigger byte address”.
The trigger byte value will be increased each time a valid transaction has been consumed by the gateway.
The trigger byte will also be increased if the offline option is set to “Clear” and the
offline timeout time value is reached.
This feature enables the control system to be notified each time new data has been
consumed on the sub-network.
• Disable
Trigger byte address
Disables the trigger byte functionality.
This parameter specifies the location of the trigger byte in the internal memory buffer.
Valid settings range from 0x000 to 0x1FF and 0x400 to 0xFFF.
Please note that the trigger byte address must be unique to each transaction. It can not
be shared by two or more transactions.

13.5 Transaction Editor
The Transaction Editor can be used to edit the individual frame objects of a transaction. The same settings are also available in the parameter section of the main window, however the Transaction Editor
presents the frame objects in a more visual manner.
Frame
Objects
To edit the value of a parameter, click on it and enter a new value using the keyboard. When editing
transactions which are based on predefined commands, certain parts of the transaction may not be editable.
The File menu features the following entries:
•
Apply Changes
This will save any changes and exit to the main
window.
•
Exit
Exit without saving.
Example:
The transaction created in this example are built up as follows:
The first byte holds the STX (0x02) followed by two bytes specifying the length of the data field
(in this case 8). The next 8 bytes are data and since this is a “query”-transaction, the data is to be
fetched from the Output Area which starts at address location 0x202. No swapping will be performed on the data. This is followed by a two-byte checksum. The checksum calculation starts
with the second byte in the transaction.
The transaction ends with a byte constant, the ETX (0x03).

14. Frame Objects
14.1 General
Each transaction consists of Frame Objects which makes up the serial telegram frame. Each Frame Object specifies how the gateway shall interpret or generate a particular part of the telegram.
There are 5 types of frame objects, which are described in detail later in this chapter:
•
Constant Objects
•
Limit Objects
•
Data Objects
•
Variable Data Objects
•
Checksum Objects
Example:
The following Transaction consists of several frame objects; three constants, a data object, and
a checksum object.

14.7 Checksum Object
Most serial protocols features some way of verifying that the data has not been corrupted during transfer. The Checksum Object calculates and includes a checksum in a transaction.
Parameter
Error Check Start byte
Error Check Type
Description
Specifies the byte offset in the transaction to start checksum calculations on.a
This parameter specifies which type of algorithm to use:
• CRC (2 bytes)
CRC-16 with 0xA001 polynome (Modbus RTU standard)
• LRC (1 byte)
All bytes are added together as unsigned 8-bit values. The two’s complement of the result
will be used as a checksum.
(Modbus ASCII standard with Error Check Start Byte = 0x01 and Representation = ASCII)
• XOR (1 byte)
All bytes are logically XOR:ed together. The resulting byte will be used as a checksum.
• ADD (1 byte)
Error check type
combined with
Representation
All bytes are added together as unsigned 16-bit values. The lowest 8 bits in the result will
be used as a checksum.
The binary value can be converted to its one’s or two’s complement. This conversion is carried
out before ASCII formatting (see next parameter).
• None
The checksum binary value is transmitted without conversion.
• One’s complement
The checksum value will be converted to its one’s complement (inverse code).
Example: 00001100 will be transmitted as 11110011
• Two’s complement
The checksum value will be converted to its two’s complement (complement code).
Example: 00001100 will be transmitted as 11110100
• Binary
The checksum is transmitted in binary format.
• ASCII
All characters in the checksum are converted to ASCII values.
a. In Generic Data Mode the Start character (if used) will not be included in the checksum calculation.

15. Commands
This information is only valid for the Master and Generic Data modes. For DF1 master mode, please
refer to “Services” on page 89.
15.1 General
As mentioned previously, commands are actually predefined transactions that can be stored and reused.
Just like regular transactions, commands consist of frame objects and are representations of the actual
serial telegrams exchanged on the serial sub-network.
Adding a command to a node actually results in (a) transaction(s) being added according to the directions
specified in the command. The frame objects in such a transaction may retrieve their values not only
from parameters in the parameter section, but also from other sources such as the “SlaveAddress”-parameter (see “Node Parameters” on page 67). In such case, the parameters in the parameter section will
be greyed out and cannot be edited directly.
In Master Mode, ACM comes preloaded with commands for most common Modbus RTU functions.
Additional commands can easily be added using the Command Editor (see “The Command Editor” on
page 83). For DF1 Master Mode, see “Services” on page 89. In Generic Data Mode, no predefined commands exist, but custom ones may be implemented as desired.
15.2 Adding & Managing Commands
To add a command to a node, right-click on the node in the Navigation Section and select “Add Command”.
A list of commands will appear:
Select the desired command in the list, and select “Add Command” in the “Command”-menu. The specified command will be
added to the node.
Just like other transactions, the frame objects of added command
may be edited in the Navigation/Parameter Section or using the
Transaction Editor. Note however that certain frame objects may
be locked for editing.

16. DF1 Protocol Mode
This mode makes the Anybus Communicator act as a DF1 protocol master on the sub-network.
16.1 General
In DF1 master mode, communication is based on “services”. A “service” represents a set of commands
and operations on the sub-network, that is predefined in the Anybus Communicator. Each service is
associated with a set of parameters controlling how and when to use it on the sub-network.
The communication is based on a query-response scheme, where the gateway issues a query on the subnetwork. The addressed node on the sub-network is expected to issue a response to that query. Nodes
are not permitted to issue responses spontaneously, i. e. without first receiving a query.
Control System
Gateway
Subnetwork Devices
In DF1 Master Mode, ACM comes preloaded with a number of services, that can be selected by the user.
The actual DF1 commands, that perform the services during runtime, are predefined in the Anybus
Communicator. The configuration of the services is performed by right-clicking on a node in the ACM
and selecting “Add Command”.

16.6 Integrity Check
This service checks that a node is up and running correctly. A telegram is sent to the node. The node
mirrors and returns the telegram. No configuration is needed, apart from the general parameters, common to all services.
16.7 Read Diagnostics
This service reads diagnostic information from the module.
Command parameters
The command parameter Size decides the amount of data that can be read. The size is given in bytes
which means that it always has to be an even number as only whole elements can be read from the slave.
One bit/integer element is 2 bytes and one float element is 4 bytes. The range of the size differs, depending on node type:
Size range (in bytes)

17. Sub-network Monitor
17.1 General
The sub-network Monitor is intended to simplify configuration and troubleshooting of the sub-network.
Its main function is to display the data allocated for sub-network communication and detect if any area
has been allocated twice (i.e if a collision has occurred).
All configured nodes, and their transactions, are listed in the middle of the screen (B). Selecting and deselecting single transactions makes it possible to view any combination of allocated data.
Note: The sub-network monitor has a negative influence on the overall performance of the gateway.
Therefore the monitor functionality should be used with care.
17.2 Operation

18. Node Monitor
18.1 General
The Node Monitor can provide valuable information when setting up the communication with the subnetwork, by allowing individual commands to be issued manually, and monitoring the response (if applicable). It also provides an overview of the memory used by a particular node.
Note: The node monitor has a negative influence on the overall performance of the gateway, i.e. it
should be used only when necessary.
The Node Monitor behaves somewhat differently in the three protocol modes:
•
Master Mode and DF1 Master Mode
The selected Command (Query Transaction) or Service is sent to the sub-network. The response
to the Query can be monitored in the Response Section.
Command Section (Query)
Subnetwork
Response Section
•
Generic Data Mode
The selected command (Transaction Produce) is sent to the sub-network. It is not possible to
monitor any responses etc. generated by other nodes.

19. Data Logger
19.1 General
This feature allows the sub-network traffic to be logged into a buffer for examination. This may provide
valuable information when debugging the lowest levels of the sub-network communication.
Note that the logger function is part of the gateway itself and is separate from ACM. This means that
logging can be performed even if the gateway is physically disconnected from the PC running ACM.
19.2 Operation
Start & Stop Logging
•
Start logging
Select “Start Logging” in the “Tools”-menu. ACM will then prompt for the desired mode of operation, see below.
•
Stop logging
Select “Stop Logging” in the “Tools”-menu. This will open the log-window, see below.
Modes of Operation
Select the desired mode of operation and click “OK” to start logging data.
•
Log until full
Data will be logged until the log-buffer is full.
•
Log continuously
Data will be logged continuously until logging is
stopped by clicking “Stop Logging”. The log-buffer
will contain the most recent data.
Log Window
The logged data is displayed in hexadecimal, decimal and ASCII format for both directions. The time between the log-entries is displayed in a separate column.
The data may optionally be saved in ASCII text format by
clicking “Create Text file”.
Click “Close” to exit.

20. Configuration Wizards
20.1 General
When creating a new sub-network configuration, the Anybus Configuration Manager provides a choice
between starting out with a blank configuration, or using a predefined template, a.k.a a wizard.
The wizard automatically creates a sub-network configuration based on information supplied by the user, i.e the user simply has to “fill in the blanks”. Note however that this will only work when the subnetwork fits the wizard profile; in all other cases the ‘Blank Configuration’ option must be used.
20.2 Selecting a Wizard Profile
The following window appears each time the Anybus Configuration Manager is started, or upon selecting the ‘New’ entry in the ‘File’-menu (unless it has been disabled in the ‘Options’-menu, see “Tools”
on page 60).
Currently, the following wizards are available:
•
Wizard - Modbus RTU Master
This option is suitable for Modbus RTU-based networks.
See also “Wizard - Modbus RTU Master” on page 101.
•
Blank Configuration
This option creates an empty configuration.
Highlight the desired wizard and click ‘OK’ to continue.

Configuration Wizards 101
20.3 Wizard - Modbus RTU Master
This wizard can be used to create a Modbus-RTU-based network configuration based on certain information about the sub-network. The online help system explains each configuration step in detail.
•
Important Notes:
Many OEM devices do not fully comply with the Modbus standard. For example, they may implement a variation of this standard or be limited to the use of specific Modbus commands other
than the ones used by this wizard. In all cases, the user should consult the documentation of the
devices that shall be used on the sub-network for information about their serial communication
requirements, and if necessary contact the manufacturer of the device to obtain further information about the serial communication protocol.
In the event that the wizard doesn’t handle a particular Modbus command required by a device,
it is possible to specify this command manually as a transaction in the Anybus Configuration
Manager.
Using this wizard involves the following steps:
Step 1: Communicator Type
Select ‘EtherNet/IP’.
Click ‘Next’ to continue.
Tip: It is possible to return to a previous
menu at any time without losing any settings by clicking ‘Previous’.
Step 1a: I/O Sizes
Specify the sizes of the input and output
data areas.
Click ‘Next’ to continue.

21. Control and Status Registers
21.1 General
The Control and Status Registers are disabled by default, but can be enabled using ACM (see “Control/
Status Word” on page 65). These registers form an interface for exchanging status information between
the sub-network and the fieldbus control system.
The main purpose of these registers is to...
•
Report sub-network related problems to the fieldbus control system
•
Ensure that only valid data is exchanged in both directions
•
Enable the fieldbus control system to start/stop data exchange with selected nodes on the subnetwork
If enabled, these registers occupy the first two bytes in the input and output data areas (0x000–0x001
and 0x200–0x201 respectively), which means they can be accessed from the fieldbus just like any other
data in these areas.
Note: Internally, these registers are stored in Motorola-format (i.e. MSB first). If the higher level network uses a different byte order, the upper and lower bytes will appear swapped.
21.1.1 Handshaking Procedure
A special handshaking procedure, which is illustrated in the two flowcharts below, must be followed
when accessing these registers to ensure that both parts receive proper information.

Control and Status Registers 103
21.1.2 Data Consistency
The “Data Valid”-bits in the Control and Status Registers are used to ensure data consistency during
start-up and fieldbus offline/online transitions.
If the “Control/Status Word”-parameter in ACM is set to “Enabled”, the gateway will wait for the fieldbus control system to set the “Data Valid”-bit in the Control Register before it starts exchanging data
on the sub-network.
If the same parameter is set to “Disabled” or “Enabled but no startup lock”, communication will start
as soon as the fieldbus goes online.
State Machine
The fieldbus network participation can be described using a state machine as described below.
A: Offline (No data exchange)
1. Clear the “Data Valid”-bit in the Control Register.
2. Write initial data to the Output Area
according to the sub-network configuration.
A
Start
Offline
(no data exchange)
3. Wait until the fieldbus control system
and the gateway are online on the fieldbus network, and shift to state B.
B
Online
(not yet exchanging data)
B: Online (Not yet exchanging data)
4. Wait until the “Data Valid”-bit in the
Status Register is cleared by the gateway.
5. Set the “Data Valid”-bit in the Control
Register.
C
Online
(exchanging data)
6. When the “Data Valid”-bit in the Status Register is set by the gateway, shift
to state C.
7. If the gateway goes offline on the fieldbus, shift to state A.
C: Online (Exchanging data)
Exchanging valid data in both directions.
If the gateway goes offline on the fieldbus, shift to state A.
Note: The gateway cannot spontaneously clear the “Data Valid”-bit in the Status Register.
Latency
The “Data Valid”-bit in the Status Register may in some cases be delayed. This latency can be caused by
a missing node or a bad connection to a node with a long timeout value assigned to it.
Therefore, the fieldbus control system should not wait for this bit to be set before communicating with
the sub-network devices; it should be considered as an aid for the fieldbus control system to know when
all data has been updated.

behavior is specific to devices from Rockwell Automation and is not defined in the EtherNet/IP specification.
However, since all known PLCs are implemented this way, the Anybus Communicator adopts this behavior
and strips off the corresponding four bytes from the consumed data.

23. Advanced Fieldbus Configuration
23.1 General
The fieldbus interface of the gateway consists of an embedded Anybus-S communication interface. Normally, the Anybus-S configuration settings are set up automatically by the gateway. However, advanced
users can configure the Anybus-S card for specific features. This chapter assumes that the reader is familiar with the Anybus-S and it’s application interface. For more information about the Anybus-S platform, consult the Anybus-S Parallel Design Guide.
The standard initialization parameters are determined by the sub-network configuration. Information
about the amount of input and output data used for sub-network communication is used by ACM to
create the configuration message that sets the sizes of the input and output data areas in the Dual Port
RAM of the embedded Anybus-S interface. It is possible to add fieldbus specific mailbox messages to
customize the initialization. This is done in the Mailbox Editor, see below.
(A mailbox message is a HMS specific command structure used for low-level communication with an
Anybus-S interface. Consult the Anybus-S Parallel Design Guide and the fieldbus appendix for the desired fieldbus for further information.)
23.2 Mailbox Editor
To add a mailbox message to the configuration, right-click on
“EndInit” and select “Insert New Mailbox”.
A mailbox message consists of a Header section and a data section where the Header consists of 16 words (32 bytes) and the data
section consists of up to 128 words (256
bytes). All fields are editable except the Message information field that is fixed to 0x4002,
which means that only fieldbus specific mailbox messages can be entered here.
A
B
The mailbox message is presented as two columns; one contains header information (A),
the other one contains the message data (B).
To add message data, simply change the Data
size parameter in the header column (A), and
the corresponding number of bytes will appear in the message data column (B).
For more information about fieldbus specific mailbox messages, consult the separate Anybus-S Fieldbus
Appendix for the fieldbus you are using. For general information about the Anybus-S platform, consult
the Anybus-S Design Guide.

Appendix A
A. Parameter Data Initialization (Explicit Data)
A.1 General
The portion of the input and output data that is declared as parameter data cannot be accessed from the
network unless it has been properly initialized.
The purpose of this procedure is to specify which data blocks in the input and output data areas to associate with the instance attributes in the Parameter Data Input Mapping Object and the Parameter Data
Output Mapping Object.
To achieve this, it is required to set up two mailbox messages in the Mailbox Editor of the Anybus Configuration Manager.
For more information about the Mailbox Editor, see “Mailbox Editor” on page 120.
A.2 Add a Mailbox Message
To add a mailbox message to the configuration, right-click on
‘EndInit’ and select ‘Insert New Mailbox’.
This causes the following window to appear:
This window, a.k.a. the Mailbox Editor, will be used in the
examples later in this chapter.
See also “Mailbox Editor” on
page 120.

Parameter Data Initialization (Explicit Data) 122
A.3 Mapping Input Parameter Data to EtherNet/IP
Example
In the following example, a total of 160 bytes of data will be mapped to the Parameter Data Input Mapping Object. The data is made up of 5 separate data blocks, each associated with a particular instance
attribute.
To achieve this, perform the following steps:
1. Add a new mailbox message to the configuration (see “Add a Mailbox Message” on page 121).
2. Change the ‘Command’-value in the mailbox header to 0084h.
3. Adjust the ‘Data Size’-value in the mailbox header (left column). In this example, the size shall
be set to 20 (0014h), since each mapped attribute occupies 4 bytes of mailbox data.
4. Specify the mapping locations for the attributes in the mailbox data section. As mentioned above,
each mapping entry needs 4 bytes; two bytes specifying the offset1 of the data block, followed by
two bytes which specify the length of the data block. Note that these values must be entered in big
endian (Motorola) format.
In this example, this gives us the following mailbox data:

A.4 Mapping Output Parameter Data to EtherNet/IP
Example
Mapping output data is similar to mapping input data; in the following example, a total of 144 bytes of
data will be mapped to the Parameter Data Output Mapping Object. The data is made up of 4 separate
blocks, each associated with a a particular instance attribute.
To achieve this, perform the following steps:
1. Add a new mailbox message to the configuration (see “Add a Mailbox Message” on page 121).
2. Change the ‘Command’-value in the mailbox header to 0085h.
3. Adjust the ‘Data Size’-value in the mailbox header (left column). In this example, the size shall
be set to 16 (0010h), since each mapped attribute occupies 4 bytes of mailbox data.
4. Specify the mapping locations for the attributes in the mailbox data section. As mentioned above,
each mapping entry needs 4 bytes; two bytes specifying the offset1 of the data block, followed by
two bytes which specify the length of the data block. Note that these values must be entered in big
endian (Motorola) format.
In this example, this gives us the following mailbox data:

B.4 Sub-network Interface
B.4.1 General Information
The sub-network interface provides for RS232, RS422 and RS485 communications. Depending on the
configuration specified in the Anybus Configuration Manager, different signals are activated in the subnetwork connector.
B.4.2 Bias Resistors (RS485 Only)
When idle, RS485 enters an indeterminate state, which may cause the serial receivers to pick up noise
from the serial lines and interpret this as data. To prevent this, the serial lines should be forced into a
known state using pull-up and pull-down resistors, commonly known as bias resistors.
The bias resistors form a voltage divider, forcing the voltage between the differential pair to be higher
than the threshold for the serial receivers, typically >200 mV.
Note that bias resistors shall only be installed on one node; installing bias resistors on several nodes may
compromise the signal quality on the network and cause transmission problems.
B.4.3 Termination (RS485 & RS422 Only)
To avoid reflections on the serial lines, it is important to properly terminate the sub-network by placing
termination resistors between the serial receivers near the end nodes.
The resistor value should ideally match the characteristic impedance of the cable, typically 100–120 Ω.

a. Connecting this signal directly to Protective Earth (PE) of other nodes may, in case of grounding loops etc., cause
damage to the on-board serial transceivers. It is therefore generally recommended to connect it only to Signal
Ground (if available) of other nodes.

D. Troubleshooting
Problem
Problem during configuration Upload / Download.
The Config Line “LED” turns red in ACM.
The serial port seems to be available, but it is not possible
to connect to the gateway
Poor performance
No sub-network functionality
Anybus Communicator EtherNet/IP/Modbus-TCP 2-port User Manual
Solution
• Serial communication failed. Try again
• The serial port may be in use by another application.
Exit ACM and close all other applications including the
ones in the system tray.
Try again
• Select another serial port
Try again
• Right click “sub-network” in the Navigation window and
select “sub-network Status” to see status / diagnostic
information about the sub-network.
If the gateway reports very many retransmissions, check
your cabling and/or try a lower baud rate setting for the
sub-network (if possible).
• Is the Subnet Monitor in ACM active?
The sub-network monitor has a negative influence on the
overall performance of the gateway, and should only be
used when necessary.
• Is the Node Monitor in ACM active?
The node monitor has a negative influence on the overall
performance of the gateway, and should only be used
when necessary.
• Use the “Data logger”-functionality to record the serial
data communication on the sub-network.
• If no data is being transmitted, check the configuration in
ACM.
• If no data is received, check the sub-network cables. Also
verify that the transmitted data is correct.
