SIMATIC Mobile Panel 277(F) IWLAN

Configuration

Configuration is carried out with the SIMATIC WinCC flexible

Standard or Advanced configuration software (see

SIMATIC WinCC flexible HMI software/engineering software).

SIMATIC WinCC flexible is the logical further development of the

field-proven ProTool family. Projects generated using ProTool

can be easily migrated to WinCC flexible. If WinCC flexible is

started directly from SIMATIC Manager, data in STEP 7 can be

accessed directly when the panel is configured. Duplicated data

input and data management is, therefore, avoided.

IWLAN infrastructure

The required IWLAN infrastructure is set up using the

SCALANCE W-700 IWLAN Access Points, preferably with the

SCALANCE W-700 variant that has two wireless cards built into

the device (Dual Access Point) and KEY-PLUG W700 iFeatures

which supports the application options of the Mobile Panel

277(F) IWLAN.

The iPCF-MC functionality (rapid roaming = fast, uninterrupted

switchover between multiple access points) is only available

with panels in version V2 or higher.

The Access Point provides an Industrial Ethernet interface for

connection to the wired network.

In addition to a reliable radio link, the SCALANCE W-700 Access

Points stand out due to their optimum support of standardized

IT mechanisms:

• IEEE 802.11b/ g/ a/ h for different frequency ranges

• IEEE 802.11e for multimedia, wireless multimedia (WMM)

• IEEE 802.11i for security

• Construction of redundant networks with the Rapid Spanning

Tree Protocol (RSTP)

• Virtual networks (VLAN) to logically separate, for example,

different user groups

• Sending the log entries of the SCALANCE W devices to a

Syslog server

Onlythe wireless approvals printed on the Mobile Panel are

binding. The RF approvals planned for all SIMATIC products can

be viewed at http://www.siemens.com/wireless-approvals.

Integration

The SIMATIC Mobile Panel 277(F) IWLAN communicates via

the WLAN Standard IEEE 802.11 a(b/g) via PROFINET. The

Mobile Panel 277F IWLAN devices also support PROFIsafe

communication.

There are five device variants with V2:

For mobile operation and monitoring via WLAN:

• Mobile Panel 277 IWLAN V2

• Mobile Panel 277 IWLAN V2 with handwheel, key switch and

illuminated pushbuttons

As fail-safe device for safety-oriented operation as well:

• Mobile Panel 277F IWLAN V2 with acknowledgement button

and emergency stop button

• Mobile Panel 277F IWLAN V2 with acknowledgement button,

emergency stop button, handwheel, key switch and illumi-

nated pushbuttons

• Mobile Panel 277F IWLAN RFID Tag (for V2 only)

For the versions Mobile Panel 277F IWLAN (PROFIsafe), the

following system prerequisites apply:

• The Mobile Panel must be connected as a safe device

(PROFIsafe, Distributed Safety)

• Use of a SIMATIC F-CPU



= Recommended

= Requirement

– = Not required

The Mobile Panel 277(F) IWLAN can be connected to:

• SIMATIC S7-200/300/400 (one F-CPU required for integrating

the Mobile Panel 277F IWLAN and SIMOTION (Mobile Panel

277 IWLAN V2 or higher, or Mobile Panel 277F IWLAN V2 or

higher (WinCC flexible 2008 SP3 or higher))

Note:

Further information can be found under "System interfaces".

The Function Manuals "Fail-Safe Operation of the

Mobile Panel 277F IWLAN" are available for downloading
