FA Wireless LAN Unit
WE70
Reliable Wireless Ethernet for Harsh FA Environments
Conforms to IEEE 802.11a/b/g
Construct an Ideal Wireless LAN System for FA Applications!
The FA Wireless LAN Unit manages
FA sites with 3 solutions
Wireless LAN systems
conforming to global standards.
Conforms to IEEE 802.11a/b/g (5 GHz/2.4 GHz)!
Nominal 54 Mbit/s high-speed communications!
The WE70 Wireless Unit supports
three Wireless LAN standards.
The appropriate standard can be
selected according to the environment
or use of the FA system.

Secure and easy to implement at FA sites.
Stable operation even in harsh FA environments!
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.
Good noise resistance
can be obtained by
connecting the Wireless
Unit to an OMRON
Power Supply Unit.
Signal status can be observed!
With the popular Received Signal Strength
Indicator (RSSI), the status of invisible
radio waves can be easily identified by
checking the indicators.

Versatile and easy installation!
This Wireless LAN Unit can be easily
installed anywhere on a DIN Rail or
a wall.
Install it in the
control panel with
other FA devices!
Use magnets to mount
it on metal surfaces!
OMRON'S original security system prevents important
production information from being disclosed.
The latest encryption technology combined with OMRON'S
original encryption technology forms a strong security
environment.

Secure and easy to implement at FA sites.
Prevents signal interference! Variable transmission power function!
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.
High transmitter output
Low transmitter output (See note.)
Note:
The transmission distance will be
shortened.
Signal interference!
Maintains good security.
Setting Tool
FA Wireless LAN settings can be made from a remote location!
Settings can be managed from a WEB browser. Specific software tools are not required.
The status of the FA Wireless LAN can be checked from the control room.
