Chapter 1 Introduction
1.1 Overview
The Wireless Gateway products provide a wireless interface between various fieldbus protocols
used in process and automation applications. The
105U-G can be fitted with different radio boards
covering regulated frequency bands in different
parts of the world, both license-free and licensed
bands.
The 105G 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 105G interfaces between 105U 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.
• Combined networks of the above.
The 105G has eight on-board discrete I/O. Each I/O
point can be configured individually as a contact input signal, or a discrete output signal. Input
signals can send via its fieldbus connection to a host device (PLC, DCS etc) or be transmitted by
radio to other 105U units. The output signals can be driven by a host device, or linked to inputs
on remote 105U units.
