Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to prop-
erty damage.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into account.

Welcome
Welcome to the Getting Started for the Mobile Panel 277 IWLAN. Taking the
Mobile Panel 277 IWLAN as an example, we will show you how to set up and
configure a WLAN wireless network. Wireless operator-control and monitoring
devices are primarily used in applications where inaccessible process stations
have to be reached quickly: cranes, high-bay warehouses, telpher lines and
even physically separated subnets. With its WLAN flexibility, the
Mobile Panel 277 IWLAN offers you great flexibility.
The Getting Started will give you a brief introduction into WLAN technology.
You can use it to perform the following tasks:
• Setting up and configuring a WLAN
• Creating a project to display WLAN wireless network quality
And finally, we will give you some useful tips on how to plan a wireless network
in a production environment.
The following components have been used for the example in this
Getting Started:

If you do not have the access point shown, you can also use a standard WLAN
router. In this event, the configuration may deviate from the configuration illus-
trated in this Getting Started.
Requirements
The access point is intended for Web Based Management.
The following WLAN configurationsettings are used by way of an example in this
Getting Started:
• IP address of the configuring PC: 192.168.1.100
• IP address of the Mobile Panel 277 IWLAN: 192.168.1.11
• IP address of the access point: 192.168.1.10
• Subnet mask: 255.255.255.0
• SSID WLAN: AP_transport_WLAN
• Network code (WPA2): Klh65Rff
Engineering offices which specialize in wireless network planning can also assist
you in planning.
This Getting Started presupposes that the configuring PC possesses WLAN-
capability. If you are in any doubt about this, contact your system administrator.
Note
The WLAN configuration described in this Getting Started also applies to
the fail-safe Mobile Panel 277F IWLAN. You can find out more on how to
configure the fail-safe Mobile Panel in the function manual entitled,
“Fail-safe operation of the Mobile Panel 277F IWLAN”.
The network code is used on
the access point and on the
Mobile Panel as a starting
p
oint for the encryption algo-
rithm. It contains up to 64
characters. Use the letters “A”
to “Z” and the numbers “0” to
“9”, mixing upper and lower-
case lettering.
