Overview
The Wireless Gateway products provide a wireless interface between various fieldbus protocols
used in process and automation applications. The WI-GTWY-9-xxx 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 105U-G units provide the same functionality as
the WI-GTWY-9-xxx, but with a fixed frequency
radio suitable for licensed frequencies in the 380 –
520 MHz radio band.
Functionality discussed in this manual for the
WI-GTWY-9-xxx range also applies to the 105U-
G range.
The WI-I/O 9-x radio protocol is designed for very
efficient radio band usage, with event reporting
communications, automatic acknowledgment and
error-correction, peer to peer addressing, multiple
path routing, and frequency encoding and data
encryption for system security.
Application types include:
•
The WI-GTWY-9-xxx interfaces between WI-
I/O 9-x wireless I/O and various fieldbus
protocols. Connect wireless I/O to PLC’s, DCS,
SCADA or Internet.
•
Wireless extension of factory automation buses such as Profibus.
•
Wireless interconnectivity between different fieldbuses - Ethernet to Profibus to Modbus to
DF1.
