HMS Industrial Networks (www.hms.se) has introduced theAnybusWirelessBridge, which extends industrial Ethernet networks wirelessly in open air over distances of up to 400 m.
This wireless bridge connects industrial devices running EtherNet/IP, Profinet and Modbus TCP through cable-free links.
Aside from offering a wireless bridge between two separate points in an industrial Ethernet network, the system is also capable of connecting devices to an existing wireless infrastructure. The company said that this makes life easier for network designers and system integrators who need to make connections in awkward locations or hazardous areas, or in moving installations with undesirable cables.
The wireless connections are created using either WLAN or Bluetooth technologies. Although the WLAN approach offers users wider bandwidth due to its broader frequency range, the Bluetooth version, however, is more favored as it is more noise-immune and reliable. This is attributed to the ability of Bluetooth technology to easily switch between different frequencies.
“We see an emerging need in the market for industrial-quality wireless communication,” said Henrik Arleving, Line Manager for Remote Management Products at HMS.
“Wireless technology is nowadays very reliable and it is becoming more and more accepted on the industrial automation market. The Anybus Wireless Bridge provides a simple solution to complicated connectivity problems and is yet another step in our efforts to make industrial networking easier.”
