3.1 General Description
As a Wireless Access Point (WAP), the device makes it possible to integrate
conventional ETHERNET devices in a wireless network. For this purpose, the
device has a wired ETHERNET interface and another interface for radio
communication. The device uses the integrated radio technology to transmit the
data received on the ETHERNET interface. Conversely, the device uses the
ETHERNET interface to send data received on the radio interface. As data
transmission of ETHERNET packets occurs with a transparent protocol on Layer
2 of the OSI reference model, this provides for easy integration of all Ethernet-
based fieldbuses, such as MODBUS/TCP, EtherNet/IP or PROFINET.
In combination with another function-related device, e.g., another WAP or Access
Point (AP) of the same radio technology, the WAP can serve as a wireless
replacement for ETHERNET cables. The WAP permits particularly robust, real-
time radio connections over long distances. A suitable configuration can also
prevent any degradation to other radio networks.

An innovative operator control concept enables easy initiation of automatic
configuration processes using a Mode membrane key on the device.
This can be used to configure a substitute cable link between two WAPs in only a
few seconds, without using additional aids or hardware / software.
Status information and advanced device functions of the WAP can also be
viewed and configured via a Web-based Management System (WBM).
Depending on the application, the unit can be operated in various modes.
