2. Anybus X-gateway Modbus-TCP
2.1 Introduction
The Anybus X-gateway Modbus-TCP is a series of network gateways, used to provide a seamless connection between a Modbus-TCP network and a controlling network. This particular product connects a
Modbus-TCP network to a PROFINET network. The X-gateway enables the controller of the PROFINET network to control the Modbus-TCP network. These X-gateways makes it possible to integrate
Modbus-TCP devices into almost any other PLC system and their supported networks.
The X-gateway is based on patented Anybus
technology, a proven industrial communication solution used all over the world by leading manufacturers of industrial automation
products. Each module offers Modbus-TCP
master connectivity to one of these industrial
networks: EtherNet/IP, DeviceNet and
PROFIBUS DP-V1, EtherCAT, ControlNet, CANopen, Modbus-TCP, Modbus
RTU, PROFINET, CC-Link.
No proprietary configuration software is
needed. All necessary configuration is made
via the built-in web interface.

2.2 Features
Anybus X-gateways for Modbus-TCP act as intelligent links between two industrial networks. On the
Modbus-TCP network, they function as clients (masters) while they function as devices (slaves) on the
PROFINET network. The implementation is based on the Anybus NP30 ASIC technology.
2.3 Configuring the PROFINET Network
The Anybus X-gateway Modbus-TCP is a PROFINET device (slave) on the PROFINET network. The
general settings for the device interface are configured using the configuration web pages (see “PROFINET (Device Interface)” on page 36). All data transfers must be configured using the PROFINET configuration tool. Please note that the size of the I/O data that can be read from and written to the module
is defined when configuring the X-gateway using the configuration web pages.
There are a number of different configuration tools for PROFINET available on the market. The choice
of tool depends on the application and the PROFINET controller of the network. A .GSD file for the
device interface is available at ‘www.anybus.com’.
An application note, describing how to configure an Anybus PROFINET IO device interface with the
Siemens Step7 PLC, is available on the support pages for the Anybus X-gateway Modbus-TCP PROFINET module at ‘www.anybus.com’.
2.4 PROFINET Generic Station Description (GSD-file)
On PROFINET, the characteristics of a device is stored in an XML data file. This file, referred to as the
‘GSD’-file, is used by PROFINET engineering tools when setting up the network configuration. HMS
provides a generic GSD-file, which corresponds to the default settings in the module.
The latest version of the GSD file for the Anybus X-gateway PROFINET interface can be downloaded
from the HMS website, ‘www.anybus.com’.

Anybus Modbus-TCP
Master Interface
Modbus-TCP network
Internally, the X-gateway consists of an intelligent gateway platform, an Anybus Modbus-TCP interface
and an Anybus PROFINET (device) interface. The Modbus-TCP interface and the Anybus PROFINET (device) interface are interconnected through the intelligent gateway platform, which basically forwards data from one network to the other and vice versa as shown below. This design allows almost any
other industrial network to be connected to a Modbus-TCP master on a separate Modbus-TCP network.

Anybus X-gateway Modbus-TCP 12
2.6 Data Exchange
Each of the two network interfaces exchanges data on its network through two buffers. The X-gateway
forwards the data between these buffers as shown below. Note that this process is separated from the
network data exchange. While the X-gateway ensures data consistency (where applicable), it does not
feature any built-in mechanisms for synchronization between the Modbus-TCP network and the
PROFINET network.

Each buffer holds a maximum of 256 bytes of data. The first two bytes in either direction can be dedicated for control/status information, and another eight bytes of data retrievable from the X-gateway by
the PROFINET network can feature a live list. Please note that the actual number of bytes that can be
exchanged is highly network dependent.
Through the dedicated control word, the controller on the PROFINET network starts/stops the exchange of data on the Modbus-TCP network, and also resets the X-gateway if needed. The controller
on the PROFINET network can see the status of the Modbus-TCP network in the corresponding status
word. The live list feature gives the controller on the PROFINET network the opportunity to continuously see and monitor the status of each individual transaction on the Modbus-TCP network.
Two additional lists, transaction status and exception codes, retrievable from the module by the master
on the PROFINET network, provides detailed error information about all transactions.
The amount of data that shall be exchanged, and the use of the control/status word and the live list, is
specified separately for each application. This means that even though up to 256 bytes of data can be
potentially forwarded to an interface, the amount of data that will actually be exchanged on that network
is determined by the Modbus-TCP settings and the limitations of the master side fieldbus.
The available control/status functionality is described below, as well as the live list and the transaction
status and exception code lists. Also note that the terminology and definitions used for different types
of data vary greatly between different networking systems.

2.7 I/O Mapped Data
I/O mapped data is cyclic data, exchanged between the networks and/or devices at a high transfer rate.
It is associated with data that is continuously sent on the network.
2.8 Parameter Data
Parameter data is usually exchanged acyclically, to set or change parameters in devices before or during
normal process. Typical parameter data that can be retrieved from the module by the master of the
PROFINET network includes the transaction status list and the exception code list.
2.9 Control/Status Word
The Control/Status word is always retrievable using acyclical access. Optionally, the Control/Status
word can also be I/O mapped. The I/O mapping can be enabled/disabled when configuring the
PROFINET network via the configuration web pages. See “PROFINET (Device Interface)” on page
36.
For information about how to access the Control/Status word, either I/O mapped or using parameter
access, see “Mapping Overview” on page 38.
The Control word is a 16-bit word (uint16) used by the PROFINET network to control the Anybus Xgateway and subsequently also the Modbus-TCP network.

2.10 Live List
The live list features the possibility for the PROFINET network to retrieve a list containing the status
of every transaction on the Modbus-TCP network.
It is accessible using parameter access, and also I/O mapped by default. The I/O mapped live list can
be enabled/disabled when configuring the PROFINET network settings. See “PROFINET (Device Interface)” on page 36. If the I/O mapped live list is enabled, it will occupy either byte 0-7 (control/status
word not enabled) or byte 2-9 (control/status word enabled and mapped to the first two bytes) in the
input data area.
All transactions and their places in the live list are also visible in the Transaction Monitor on the configuration web pages.
The live list consists of a bit array with 64 elements, where each bit corresponds to a transaction on the
Modbus-TCP network as in the table below.
Byte 7
Byte 6-1
Bit 63
Bit 62-56

Bit set to 0
Transaction not successful.
Note: the reason for the unsuccessful transaction can be found on the corresponding index in
the transaction status list.
The order of the transactions in the live list conforms to the order in which they are stored in the Modbus Server list.
Example
Consider the following configuration:
•
Server 1 : a total of 2 transactions
•
Server 2 : a total of 3 transactions
•
Server 3 : a total of 1 transaction
This scenario will produce a live list as follows (assuming that the transactions are successful):

3.2 Mounting the X-gateway
The Anybus X-gateway Modbus-TCP can be physically installed either by mounting it onto a DIN-rail
or, if installed in areas exposed to vibration, by mounting it on a wall for more stability.
3.2.1 DIN-rail Mounting
Make sure the DIN-rail fastening mechanism on the back of
the module is in a fixed and closed position, i. e. pushed all the
way up.
To mount the module, first hook it on to the DIN-rail (1),
then push it against the DIN-rail to make it snap on (2).
To unmount the module, a screwdriver is needed. Use the
screwdriver to push the DIN-rail fastening mechanism on the
back of the module down until it locks in a fixed and open position (1). Then unhook the module from the DIN-rail (2).
Note: Do not leave the module with the DIN-rail fastening
mechanism in a fixed and open position. This may eventually
wear the fastening mechanism out so it cannot be used efficiently. Be sure to push the DIN-rail fastening mechanism
back into the fixed and closed position after unmounting the
module.

3.2.2 Wall Mounting
Use the wall mounting option if there is a need to place the X-gateway in an environment exposed to
vibration. This way of mounting the module offers more stability than the traditional DIN-rail mounting.
Note: The X-gateway should be fastened in a standing-up position, to ensure a constant air flow.
Note: When mounting the X-gateway to a wall using the wall mount option, do not forget to connect
the module to protective earth (PE) via the power connector. See “Power Connector” on page 22.

4. SD Card Functionality
Using an SD card with the X-gateway adds the following features:
•
Easy backup.
Every applied change in the configuration will automatically be saved to the X-gateway and the
SD card. See “Easy Backup” on page 24.
•
Simple configuration copy.
Using the SD card, the configuration on one X-gateway can be copied to other X-gateways. See
“Simple Configuration Copy” on page 24.
•
Easy replacement.
If an X-gateway malfunctions during operation, a replacement module can easily be configured
by moving the SD card to the new module. See “Easy Replacement” on page 24.
A configuration on the X-gateway is saved automatically to the SD card in any of these two events:
•
A configuration is applied in the X-gateway Management section
•
A configuration is restored from a backup file
Important
The SD card acts as a master in the X-gateway. When an X-gateway is turned on with an SD card inserted, and that SD card contains a valid configuration file, the configuration on the SD card will always
overwrite any configuration on the X-gateway.
4.1 General Advice and Guidelines
Turn the power off before inserting or removing an SD card from the X-gateway.
Do not turn the X-gateway off while the SD LED indicates that the SD card is being accessed. Refer to
“Status LEDs” on page 17 for more information.
The X-gateway will not write any data to a write-protected SD card.
4.2 Starting Up
1. Format the SD card for the FAT file system using a PC. The X-gateway cannot use an unformatted SD card.
2. Make sure the SD card is empty and that it is not write-protected.
3. Turn the X-gateway off.
4. Insert the SD card into the SD card slot in the X-gateway.
5. Turn the X-gateway on.
6. Create the configuration. When finished, press the apply button in the X-gateway Management
section to reboot using the new configuration. During the reboot, the latest applied configuration
will automatically be copied and saved to the SD card.
7. Now, the SD card is synchronized with the X-gateway. Both the SD card and the X-gateway contain the latest applied configuration.
Every time a new configuration is applied in the X-gateway Management section, it is also copied to the
SD card to ensure synchronization.

SD Card Functionality 24
4.3 Easy Backup
Every time a configuration change is applied in the X-gateway Management section using the configuration web pages, the configuration is saved both in the memory of the X-gateway and on the SD card.
This is the easiest way of keeping a continuously updated configuration backup.
4.4 Simple Configuration Copy
If a configuration on one X-gateway needs to be copied to one or more other X-gateways, it is easily
done using an SD card.
1. Turn the X-gateway running the desired configuration off.
2. Remove the SD card from the X-gateway containing the desired configuration and insert it into
another one.
Note 1: The firmware version must be the same or higher in the new X-gateway.
Note 2: The new X-gateway must support the same network type as the first X-gateway.
3. Turn the new X-gateway on. The new X-gateway will automatically start up using the configuration found on the SD card.
Important
If the configuration was protected by authentication information, the same information will be needed
to alter the configuration in the new X-gateway.
4.5 Easy Replacement
If an X-gateway malfunctions during operation, the SD card functionality makes it easy to get the application up and running again fast.
1. Turn the malfunctioning X-gateway off.
2. Replace the old X-gateway with a new one.
Note 1: The firmware version must be the same or higher in the new X-gateway.
Note 2: The new X-gateway must support the same network type as the old X-gateway.
3. Remove the SD card containing the configuration file from the old X-gateway and insert it into
the new one.
4. Turn the new X-gateway on. If the SD card contains a valid configuration file, the X-gateway will
automatically start up using the configuration found on the SD card.
Important
If the configuration was protected by authentication information, the same information will be needed
to alter the configuration in the new X-gateway.
Depending on the settings of the master network, the communication link between the X-gateway and
the master may no longer be valid. X-gateway settings that were configured from outside the configuration web pages will need to be set again.

SD Card Functionality 25
4.6 SD Card Synchronization Failure
In the event of applying a configuration or restoring a configuration from a backup file, the SD card
synchronization can fail. There are many possible reasons for an SD card write failure:
•
The SD card is write-protected.
•
The configuration file on the SD card is write-protected.
•
The SD card memory is full.
•
The SD card file system is corrupt.
•
The SD card is damaged.
If the SD card write process fails, the reboot cycle of the X-gateway will halt. The GW LED will indicate
“invalid configuration” and the SD LED will indicate “failure”. See “Status LEDs” on page 17.
To eliminate the problem, follow the steps below:
1. Turn the X-gateway off.
2. Remove the SD card. Find the cause of the problem.
3. Insert an SD card.
Note: This SD card must not contain a configuration file. If it does, the configuration on the SD
card will overwrite the configuration on the X-gateway.
4. Turn the X-gateway on. The X-gateway will run the configuration that was applied or restored
when the SD card write process failed.
5. Apply the configuration in the X-gateway Management section to save the configuration to the
SD card.
6. Now, the SD card is synchronized with the X-gateway. Both the SD card and the X-gateway contain the latest applied configuration.

5. Modbus-TCP Functions
The Modbus-TCP protocol is an implementation of the standard Modbus protocol, running on top of
TCP/IP. The same function codes and addressing model are used.
The Anybus X-gateway Modbus-TCP supports a subset of the functions described in the Modbus-TCP
specification.
Modbus-TCP transactions are normally transmitted and received on TCP port no. 502. The X-gateway
features the possibility to set TCP ports individually for each Modbus-TCP server.
For detailed information regarding the Modbus-TCP protocol, consult the Open Modbus-TCP Specification.

6. Network Configuration
6.1 General Information
The Anybus X-gateway features built-in web pages for easy configuration. The web pages are all described in this chapter. To access the web configuration pages, the following system requirements need
to be met:
•
Internet Explorer 8.0 or 9.0
•
Javascript enabled
Note: Altering the configuration while the X-gateway is exchanging data between the two networks may
affect performance.
Note: Only one user at a time should be accessing the configuration web pages. If two or more users
make simultaneous changes to the configuration, the configuration saved last will overwrite other changes.
There are things to take into consideration when making the configuration.
•
Remember to apply the configuration in order for changes to take effect. See “X-gateway Management” on page 37. As soon as you have saved data to the configuration but not yet applied it,
you will see the box below at the top of the web pages:
•
A maximum of 64 Modbus-TCP servers can be added to the configuration.
•
A maximum of 61 transaction units can be set up to the servers in the configuration.
•
Take care when choosing scan times for the transactions. The mimimum allowed scan time (ms)
is the total number of transaction units multiplied by three and cannot be less than 10 ms.
•
Take care not to map too much data. The data (including both I/O mapped data and parameter
data) limits are 256 bytes input data and 256 bytes output data, including optional control/status
word and live list.

6.2 Introduction
To display the configuration and status web pages of the X-gateway, start a web browser and type the
IP address of the module in the address field.
The default IP address of the X-gateway is 192.168.0.100. To connect a computer to the X-gateway,
make sure that both the computer and the module are using the same subnet mask, e.g. 255.255.255.0.
Change the IP address of the computer to 192.168.0.X, where X is any number between 0 and 255 except 100.
If, for example, there is a DHCP server on the network, the IP address might be unknown. In that case,
use the Anybus IPconfig tool to find it. The Anybus IPconfig tool can be downloaded from www.anybus.com.
If a list of connected devices does not show automatically, press the scan button. Identify the IP address
of the X-gateway by its type ‘Anybus X-gateway Modbus-TCP’ or by its MAC address. The MAC address of the X-gateway can be found at the bottom of the module.
For additional information about the Anybus IPconfig tool, see “Anybus IPconfig Tool” on page 43.

Default name is ‘New_Trans’, followed by an incrementing suffix.
Max length: 32 characters.
Timeout (ms)
The time span within which the server must return a response to the transaction.
If no response is received within the timeout period, the connection to the server will be closed.
If the connection to the server is closed, all transactions to that server will be affected .
Value range: 10 - 65535 (ms).
Scan time (ms)
The scan time defines how often the transaction shall be resent, e.g. the time cycle of a repeating
transaction.
Minimum scan time (ms) is calculated by multiplying the total number of transactions by three.
The minimum scan time will increase by adding more transactions.
Value range: 10 - 10000 (ms).
Unit ID
Only applicable for Modbus RTU servers. If the Modbus-TCP server functions as a router to Modbus RTU servers, it is possible to send transactions to a single Modbus RTU server using the unit
ID.

6.5.1 X-gateway Management
Apply changes
Permanently store changes made to the configuration and reboot, using the new configuration.
No changes made in the configuration will be permanently stored or used by the X-gateway until they
are applied by clicking ‘Apply’.
Before storing and rebooting, the X-gateway will validate the not yet stored configuration. If errors are
found, the X-gateway will produce an information message with instructions to correct the errors. The
X-gateway will not store an invalid configuration.
Reboot and undo changes
The X-gateway will be restarted. All changes made since the last configuration was loaded will be undone.
Undo changes
Undo all changes made since the last configuration was loaded.
Factory reset
Reset the X-gateway to completely remove the configuration currently stored in the module.
Wink device
Clicking the “Wink device” button will start a 15 second LED sequence on LEDs 1, 5 and 6 on the Xgateway. For identification purposes.
6.5.2 Backup and Restore
Backup the configuration that is currently used to file, or restore a previously saved configuration from
file.
It is not possible to backup or restore the configuration until all changes are either applied or undone.
See “X-gateway Management” on page 37.
Two things can happen when loading an old configuration:
•
Configuration valid:
The X-gateway will reboot and automatically use the previously stored configuration.
•
Configuration not valid:
The X-gateway will produce an error message. The chosen configuration will not be accepted or
loaded into memory.
Important Notice
Before loading a previously stored configuration, locate any authentication information associated with
it. If a valid configuration is loaded that is protected by a password, the X-gateway can not be reconfigured until the authentication information has been provided.

6.5.3 Mapping Overview
This page provides a description of all data resulting from the transactions of the currently applied configuration. It is divided into two parts. The first part describes the X-gateway interface to the PROFINET network, and the second part all applied transactions on the Modbus-TCP network.
If needed, it is possible to print the configuration to paper. Click the printer symbol to the right on the
mapping overview page to access a printer friendly version of the mapping overview.

Slot details, cyclic I/O
A description of the slots resulting from the I/O mapped transactions of the currently applied
configuration. If I/O mapped control/status word and live list are enabled, they also show here
in separate slots. The slots each contain a maximum of 64 words of data. If the configuration
contains more than 64 words in either input or output data, the data will be split up in two or
more slots. When configuring the PROFINET PLC, take care to retain the slot order as seen in
the data section in the overview.
The I/O data will always be divided into slots according to the following priority order:
- Control/status word (optional)
- Live list (optional)
- Input data (bit transactions will always be mapped first)
- Output data (bit transactions will always be mapped first)
All data from the PROFINET network to the Modbus-TCP network (write data) will be mapped
as output data. In the same way all data from the Modbus-TCP network to the PROFINET network (read data) will be mapped as input data.

Parameters, acyclic I/O
A detailed list of all data, including both the I/O mapped and the not I/O mapped data, available
from the X-gateway to the PROFINET network. This list also includes the transaction status and
exception code lists, available for error identification.

6.5.4 Mapping Overview Example
Note that changes to the configuration that are not applied and saved will not show in the overview.
This example includes four transactions. The control/status word and the live list are both I/O mapped.
The resulting slots for the I/O mapped data can be found in the configuration data box and a detailed
view is available in the slot details box:
- New_Trans1: an I/O mapped read/write transaction, reading two bytes and writing two
bytes.
- New_Trans2: an I/O mapped read transaction, reading a total of eight bytes.
- New_Trans3: an I/O mapped write transaction, writing 14 bits. Notice how it is placed before New_Trans1 in the list.
- New_Trans4: a not I/O mapped read transaction, reading a total of eight bytes. Notice how
this transaction is only available from the parameter data box.
In the parameter data box, all configured data is presented. Details for acyclically accessing control/status word, live list, exceptions list and trans-status list, as well as both I/O mapped and not I/O mapped
data, are available here.

6.5.5 Transaction Monitor
The transaction monitor interface presents a detailed list of all transaction currently operating on the
Modbus-TCP network. The data is automatically updated, and it is possible to choose to view the data
either in decimal or in hexadecimal values. The time that has passed since the last update is visible at the
top of the transaction list. Every post in the list contains the following transaction information:
•
Server name and transaction name
•
The type of Modbus function chosen for the transaction
•
The size of the data read from or written to the Modbus-TCP network
•
The actual data read from or written to the Modbus-TCP network
•
The bit position of the transaction in the live list (also presented as byte.bit).
If there is a transaction error, an error message will appear instead of the data.
A red frame around the list indicates that the web browser has lost connection to the web server of the
X-gateway. If this happens, try reloading the page by clicking on “Transaction Monitor” in the menu to
the left.
Note: Viewing the transaction monitor may affect performance.

B. Anybus IPconfig Tool
The X-gateway supports the HICP protocol used by the Anybus IPconfig tool and all Anybus products.
It is possible to see and alter the TCP/IP settings for the X-gateway manually by using the
IPconfig Tool.
At start-up, the IPconfig tool presents a list of
all Anybus products that are connected to the
network. The list can be refreshed by clicking
‘scan’. The X-gateway is identified in the list
by its type ‘Anybus X-gateway Modbus-TCP’
or by its MAC address (found at the bottom
of the module).
Right-clicking a row in the list makes it possible to either visit the web interface of the
product, or bring up the configuration window. Double-clicking a row also brings up the
configuration window.
In the configuration window the TCP/IP settings can be set or changed. Save the new settings by clicking ‘set’, or exit without saving by clicking ‘cancel’.
Note: the IPconfig tool provides the opportunity to set a username and a password. The X-gateway,
however, will not accept any configuration changes where the password has been altered.
Note: if the X-gateway configuration is protected by a password, it is not possible to alter the TCP/IP
settings.
