Support Rapid Roaming capability for Up to 50 Ethernet Clients
-
Rapid Roaming offers real-time wireless communication and allows the Ethernet clients to move from one radio cell (Access Point) to another at high speed up to 50 MPH
Configuration backup using "C-PLUG" to simplifiy equipment maintenance for engineers
-
SCALANCE W automatically store configuration data on a removable plug called C-PLUG. When the maintenance engineer needs to replace a defective unit in the field, only the C-PLUG must be transferred to its replacement. The replacement unit can start operating immediately with the same configurations copied from the C-PLUG retrieved from the original unit.
Fully support IEEE 802.11 Wi-Fi, a recognized worldwide industry standard
-
SCALANCE W supports all 802.11a, 802.11b and 802.11g standards and both 2.4 GHz and 5 GHz frequencies.
Support dedicated data channel for critical wireless clients for deterministic real-time industrial applications
-
The randomly controlled access process describled in IEEE 802.11 is sufficient for most office applications. However, an exactly timed process is necessary for industrial control units and peripheral equipment with cyclical data exchange. Therefore, SCALANCE W Access Point offers the options of dedicating a defined data channel in advance for critical clients, thus allowing time-critical connections to be realized via the industrial wireless network.
Support strongest wireless data security and encryption functions for your important industrial network data:
-
Wi-Fi Protected Access (WPA) with RADIUS server. Encryption support AES and TKIP
-
Wi-Fi Protected Access-Preshared Key (WPA-PSK). Requires no external RADIUS server, uses preshared key between clients and access points.
-
802.1x with RADIUS server
-
Wired Equivalent Privacy (WEP), 64-bit and 128-bit
Designed specifically for the industrial environment
-
Shock, vibration resistance
-
IP65-rated metal enclosure
-
Class I Div 2 & Zone 2 ceritified for hazardous locations
-
Redundant 24VDC power inputs
Support optional 2nd independent wireless RF interface
-
The second RF radio interface can be configured independently for 802.11b, 802.11g or 802.11a for use either as 2nd wireless connection or for redundancy
Active Antenna Diversity allows reliable sending and receiving and avoiding wireless dead zones.
-
In order to bypass spatially limited wireless dead zones, Active Antenna Diversity comes standard with SCALANCE W. Between 2 antennas, the strongest signal is constantly used for the data transmission.
