The latest encryption technology combined with OMRON'S
original encryption technology forms a strong security
environment.
The FA Wireless LAN contains the following security features.

Secure and easy to implement at FA sites.

With the popular Received Signal Strength
Indicator (RSSI), the status of invisible
radio waves can be easily identified by
checking the indicators.

Various antennas are available for different installation locations (optional).

Stable operation even in harsh FA environments!

OMRON'S original security system prevents important
production information from being disclosed.

Signal status can be observed!

Versatile and easy installation!

The Wireless LAN Unit has the same level of noise and
environmental resistance as OMRON FA Devices, such as
PLCs and Power Supply Units. It is capable of stable
operation when installed within the same control panel as
other FA devices.
There is no need to reset
the power supply even
if the Wireless LAN
Unit runs out of
control because it
will automatically
restart itself.

Note: Partly quoted from the Wireless Security Guidelines (Ministry of

Internal Affairs and Communications).

This Wireless LAN Unit can be easily
installed anywhere on a DIN Rail or
a wall.

In addition to the included Pencil Antenna, the popular Magnetic-base Antenna is available.
The FA Wireless LAN Unit can be installed inside the control panel and the Antenna on the
outside of the control panel.

Good noise resistance
can be obtained by
connecting the Wireless

Secure and easy to implement at FA sites.

There are three transmitter output levels. By setting the level to low, you can reduce its influence on other systems within the
same area, and more systems can be added.

Prevents signal interference! Variable transmission power function!

Note: The transmission distance will be

shortened.

Setting Tool

Up to 63 clients can be connected to one access point.
Communications between access points enables switching of access
points when expanding the communications area or when there is a
communications error.

Note: Make sure that you read the Wireless LAN Unit Operation Manual (Cat. No. N153)

and check the operating conditions on site before using the roaming function.

Diverse systems to match applications.

Large quantities of production data can be managed as a batch.

The roaming function allows systems to be moved and communicate with mobile devices.
