Anybus X-gateway Modbus TCP

Anybus X-gateway - Modbus-TCP Master/Client

Integrate your Modbus-TCP network to Fieldbus/Industrial Ethernet
With the powerful Modbus-TCP X-gateways, you can integrate a Modbus-TCP network to another controlling network — quickly and easily without the need for any programming.

Fast and powerful network translators
The X-gateway acts as translator between a Modbus-TCP network and another industrial network. The primary focus is the fast transfer of cyclic I/O data between Modbus-TCP and the other chosen network (approx 5ms). With the Modbus-TCP Master/Client functionality, the X-gateway can eliminate the need for a Modbus-TCP PLC Client/Master on the Modbus-TCP side and thus help reduce infrastructure costs.

Modbus TCP Master/Client functionality
On the Modbus-TCP down link side the Anybus X-gateway supports a maximum data size of 256 byte input and 256 byte output, including Control and Status words. The X-gateway can manage up to 64 Modbus servers, and up to 64 different input/output transactions can be configured and visualized in the mapping overview of the configuration web pages. Via the live list, every transaction can be closely monitored by the PLC to minimize down time.

Fieldbus/Ethernet Slave functionality
On the Fieldbus/Ethernet uplink side the X-gateway appears as a standard I/O module and is configured using a standard device description file (GSD/EDS) with the PLC engineering tool.

Easy visual web-based configuration - No programming required
Configuration is handled through a web interface which is accessed by simply connecting the gateway to a computer via a regular Ethernet cable. No programming skills are required which means that the network and its devices will be up and running in no time.

Dual port Ethernet switch technology
On the Modbus TCPside, the x-gateway is equipped with an integrated 2-port switch on the Ethernet side, enabling Ethernet installations in bus or line topology without the need for external switches. As a result, system integrators can benefit from significantly reduced installation and maintenance costs.

Modbus TCP is often very popular within process automation, measurement and with sensor and actuators. It fits with all types of energy distribution and control applications including renewable energy.

Fieldbus migration
Typical applications are industrial applications on established fieldbus networks from Siemens, Rockwell, Beckhoff, ABB, Mitsubishi which require integration into an upgraded Ethernet Modbus TCP network.

Ethernet to Ethernet
In addition to fieldbus migration, the X-gateway is also equally adept at inter-linking two modern similar or dissimilar Industrial Ethernet networks. The Master/Client capaiblity of the X-gateway enables substansial cost savings.




Application example: Profibus to Modbus TCP migration and EtherNet/IP to Modbus TCP

Easy visual web-based configuration
Configuration is made via Ethernet and a built-in web page. The configuration page is used to configure 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) in the PLC engineering tool.

A configuration example video for the Anybus X-gateway Modbus-TCP Client/Master. In this example the uplink slave network is Profibus. The same pricinple can be applied to connect other supported slave networks of the X-gateway Modbus-TCP.


 


How to configure Anybus X-gateway for Modbus TCP
Anybus X-gateway configuration example

Fast data mapping
The Anybus X-gateway Modbus-TCP appears as a standard I/O module on the up-link network. It transmits I/O-data in both directions in a cyclical manner ensuring the fastest possible performance.

The Modbus-TCP side is configurable to send data cyclically or in a change-of-state manner. It basically forwards I/O data from one network to the other and vice versa as shown below. Status and Control words are available as well as a Live List telling the status of the Modbus-TCP downlink Modbus transactions.

Each of the two network interfaces exchanges data on its network through internal I/O buffers. The gateway forwards the data between these buffers as shown above. On the Modbus-TCP Client interface, the dedicated control word is used to start/stop the exchange of data, or to reset the gateway if needed.

The master on the uplink network (e.g. Profibus) can see the status of the Modbus-TCP network in the corresponding status word.

All new enhanced design for streamlined connectivity
The X-gateway Modbus TCP design meets the industrial demands for functionality, robustness, size, durability and most importantly ease of use. It offers many benefits for the user such as easier cable connection and backplane stacking possibilities.

Handy SD memory card slot saves time and know how
The design also includes an SD memory card slot for fast and easy backup, configuration and if necessary for an "easy module replacement" which saves crucial time and resources.
