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

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

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.
