1Welcome

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

The network code is used on the access point and on the Mobile Panel as a starting

oint for the encryption algorithm. It contains up to 64 characters. Use the letters “A” to “Z” and the numbers “0” to “9”, mixing upper and lowercase lettering.

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 illustrated in this Getting Started.

Requirements

The access point is intended for Web Based Management. The following WLAN configuration settings are used by way of an examp le 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 netwo rk 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”.

2 Configuring the WLAN

The access points permit a Mobile Panel to roam from one access point's wireless range to that of another access point.

2.1 What is a WLAN?

Data is transmitted and received by radio waves in WLAN instead of via cables. Mobile HMI devices such as the Mobile Panel 277 IWLAN conduct wireless communication with the PLC via the access point, which makes them very flexible to use, e.g. for maintenance and diagno st ics.

Minimum configuration

A WLAN configuration comprises the following components, at least, in automation technology:

• Access point The access point is the link which connects the wireless HMI device and the

wire-bound network, e.g. Ethernet.

• Configuring PC Two tasks are performed with the configuring PC in the WLAN:

• You can use it to configure the access point's WLAN parameters.

• You can use WinCC flexible to configure the project for operating and

monitoring and transfer it via WLAN to the Mobile Panel.

• Mobile Panel 277 IWLAN The Mobile Panel 277 IWLAN is a portable, wireless HMI device on which the

process is displayed and operated. The Mobile Panel 277 IWLAN can be used to operate and monitor machines and plant control systems directly onsite with visual contact.

2 Configuring the

WLAN

transmitter's range at

2.4 GHz is between 30 and 100 m. The range depends on the antenna, on objects in the way indoors, on surfaces and on materials. Operation at 5 GHz has a lower range, although it is more resistant to radio interference. All SIEMENS access points are designed for industrial use.

• Plant control system The PLC transmits the process data to the access poin t via Ethernet and

receives the operating data about the Mobile Panel from it.

How it works

WLAN uses electromagnetic waves for wireless data transmission. The IEEE 802.11 process use d for WLAN transmits on the frequencies 2.4 GHz and 5 GHz which are available license-free to all countries. Only one station can transmit at any one time on each of a frequency's channe ls (sim p lex mod e ).

Security

SIEMENS access points support all the current me asures to secure yo ur WLAN. Take the following steps to avoid unauthorized access to the WLAN:

1. Select a secure encryption process.

All SIEMENS access points support WPA2 with AES and TKIP, which is currently regarded as the most secure encryption process.

2. Password-protect the access point.

The access points support MAC address filters as well as the encryption processes WEP, WPA2 with AES and TKIP, EAP-TLS and EAPPEAP. You can find additional information about the individual security processes in the system manual entitle d “SIMATIC NET, Basics of Industrial Wireless LAN”.

3. Select an SSID (service set identifi er) whi ch does no t in d ic ate th e hardware used.

2.2 Configuring the Access Point

Configuration during Commissioning with the Primary Setup Tool

The Primary Setup Tool is used to configure the access point. The WLAN is set up when you commission an access point. The Primary Setup Tool is supplied in the access point package.

Requirements

• The access point has a power supply and is switched on.

• The Primary Setup Tool is installed on the configuring PC.

• The configuring PC is connected to the access point by a network cable.

oints in a wireless network, simply upload the saved configuration data to the other access points.

The access point is configured for commissioning. Further configuration is performed via the Web Based Management.

Configuring WLAN Settings for the Access Point with Web Based Management

The Web Based Management represents the homepage for the access point. Configure the WLAN settings for the access point using the Web Based Management. This includes the the security settings, such as encryption, or the name of the WLAN.

Ensure that JavaScript is enabled in the browser and that the firewall permit s access to port 80.
