April 27, 2011 - HMS introduces Anybus X-gateway for Modbus TCP.  With slim housing, web-based configuration, easy cable connection and an SD card slot for easy module replacement, the gateways are designed to make life easier for system integrators. The gateway enables communication between Modbus TCP (widely used within process automation, measuring, sensors and actuators etc.) and PLC networks on Profibus, DeviceNet and EtherNet/IP.

As all Anybus gateways, the X-gateway for Modbus TCP solves important connectivity issues for system integrators working with industrial network design. These issues include connecting two otherwise incompatible networks in a factory, migrating to a newer network standard or expanding the length of an existing network.

Design makes system integration easier
The gateway design offers many benefits for the user such as easier cable connection, backplane stacking possibilities and a wall-mount option for harsh industrial environments. The gateways are designed to operate in rugged industrial conditions and are certified by CE, RoHS, UL, Haz.Loc, ATEX, with Marine certification pending (AICS E10DNC 2.4).

How it works
The X-gateway works as a client/master on the Modbus TCP network (which can eliminate the need for an additional PLC or master) and a slave/adapter on the Profibus, DeviceNet and EtherNet/IP network. It is connected via a 24 VDC power supply, has a power consumption of no more than 150 mA and passes up to 256 bytes of transparent, cyclic I/O input and output data. The new gateway is designed to provide a very fast transfer of I/O data between networks, typically with a delay of no more than 5ms.

The dual Ethernet port on the down-link side allows daisy-chaining and eliminates the need for parallel wiring. Configuration is handled through a web interface without the need for any programming. By using an SD memory card, the gateway can be exchanged without any configuration at all which shortens the down time considerably.

What is an X-gateway?
Anybus X-gateways allow two different networks to talk to each other. In simple terms you could say that it is a real-time translator between any two networks. Gateways solve important industrial communication issues for system integrators working with industrial network design and offer a quick and easy way to connect two otherwise incompatible networks.
