The easy way to configure a Modbus TCP network!


The Anybus X-gateway Modbus TCP configuration is made via built-in web configuration pages. No scripting or programming is needed as you are guided through an easy-to-use visual configuration method.

Here you set the Ethernet TCP/IP settings, Modbus-TCP Client/Server configuration and I/O data size transfer between Modbus-TCP and the chosen network.

The uplink fieldbus or Ethernet slave interface to the PLC is configured with a standard device description file (GSD/EDS/XML) in the PLC engineering tool.

Modbus TCP Configuration features

  • Configure the communication between Modbus TCP and another network in a matter of minutes.
  • Authorization and user/password setup protects your configuration
  • Simple visiual Modbus TCP Client/Server configuration
  • Live list to inform the uplink PLC the status of connected Modbus TCP server devices

Get a status overview

When accessing the web page configuration, you are presented with the configuration and status web pages, which present important error tracking information, as well as general information and statistics.

Here you can also secure your configuration by enabling or disabling "Administrator Authentication". If enabled, it is possible to set a username and password to protect the configuration.


Set up the Client interface

There are different options to use when configuring the Client network settings. If not set by DHCP (or HICP), you can set these values manually. DHCP is enabled by default. When enabled, the X-gateway can obtain the TCP/IP settings dynamically from the DHCP server of the Modbus-TCP network.

Anybus IPconfig (HICP) is enabled by default. When enabled, the TCP/IP settings for the Modbus-TCP network can be configured temporarily with the included software "Anybus IPconfig tool".


Configure the Modbus servers

The configuration of the servers on the Modbus-TCP network is made here. The X-gateway can handle up to 64 different servers, and a maximum of 64 transactions distributed among those servers.

Once the server setup is complete, you can then click ‘Add new server’ to add a Modbus server to the configuration. Click ‘Edit’ to see and edit the settings.


Add your transactions

Transactions represent the data that is read from/written to the servers of the Modbus-TCP network. 

The global configuration limits box keeps track of the number of added transactions, the current minimum allowed scan time, and the current amount of I/O mapped data as well as total amount of data (both I/O mapped and not I/O mapped data).


Set up the other network

Here you can easily setup the other chosen gateway network and set the I/O data size. Enabling or disabling the mapping of the control/status word (depending on chosen network) and Live List features are also made here.

By returning to X-gateway Management and "Apply changes," you 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’. 


Handy Live List

The transaction monitor interface "Live List" presents a detailed list of all transactions 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.


SD Card storage slot

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. 
  • Simple configuration copy - Using the SD card, the configuration on one X-gateway can be copied to other X-gateways. 
  • Easy replacement - If an X-gateway malfunctions during operation, a replacement module can easily be replaced.


SD Card

What you can do!

Connect any two industrial networks — Fieldbus, or Industrial Ethernet or connect to IT systems via MQTT or OPC UA.
