Trusted Wireless 2.0: industrial wireless technology
The proprietary Trusted Wireless 2.0 wireless technology was specifically developed by Phoenix Contact for industrial use. It is particularly suitable for forwarding sensor and actuator information wirelessly as well as transmitting low to medium volumes of data in large systems. With a clear line of sight, distances ranging from several hundred meters up to several kilometers can be covered between two wireless devices.
Trusted Wireless 2.0 therefore closes the gap between WirelessHART as a special technology for sensor networks and Wireless LAN high-speed technology.
Various setting options are available to adapt it optimally to the requirements of the relevant application. The technology is used in the industrial Radioline wireless system from Phoenix Contact.
Technologies such as WirelessHART or ZigBee use a central approach to network management. That means that all messages pass through a central master, which can lead to significant wireless network traffic.
Trusted Wireless 2.0 on the other hand uses distributed network management. For this purpose, so-called parent-child zones are constructed in the wireless network, where a higher-level wireless module is called the parent and the modules connected to it are called children.
All network management takes place within the parent-child zone and does not have to be directed through the central manager. This reduces message traffic throughout the whole network and accelerates data exchange.
Trusted Wireless 2.0 provides the option of setting the data rate of the wireless interface and thereby increasing the receiver sensitivity. With a low data rate you can cover significantly greater distances than with a high data rate. Therefore, the user can choose an appropriate setting based on the application and required range.
The Radioline wireless system from Phoenix Contact enables the easy and flexible construction of point-to-point connections, star networks or mesh networks and transmits I/O signals as well as serial data. With Radioline, I/O modules can also be connected to the controller directly via the integrated RS-232 and RS-485 interface using the Modbus protocol.
Trusted Wireless 2.0 and the Radioline wireless system have been specially developed for industrial use for the transmission of serial control data or analog or digital I/O signals. This combination is particularly suitable for use in large systems and networks, for example in the field of water/wastewater or in process engineering.
