905U-G Wireless Gateway
 |
The 905U-G Wireless gateway products provide a wireless interface between various data buses used in process and automation applications. The 905U-G includes an integral 900MHz license-free radio transceiver, and transfers transducer and control signals (I/O) using a highly secure and highly reliable radio protocol.
The 905U radio protocol is designed for very efficient radio usage, with configurable communications based on event reporting (I/O change), update times and/or poll response. Other features are:
high security data encryption
automatic acknowledgment and error-correction,
peer to peer addressing, and
mulitple path routing
Applications include:
- The 905U-G interfaces between 905U wireless I/O and various data buses. Connect wireless I/O to PLC’s, DCS, SCADA or Internet.
- Wireless extension of factory automation buses such as Profibus and Ethernet, providing a high security firewall.
- Wireless interconnectivity between different data buses - Ethernet to Profibus to Modbus to DF1.
- Combined networks of the above, forming an Elpro WIB (“Wireless Instrumentation Backbone”).
The 905U-G modules also have eight on-board discrete I/O, individually configurable as input or output. Network configuration is performed with easy-to-use free software.
I/O links are configured between different modules in the network.
