The SCALANCE W746-1PRO Ethernet client module is highly suitable for integrating devices with an Industrial Ethernet con- nection into Industrial Wireless LAN (IWLAN) radio networks with reliable communication. The SCALANCE W746-1PRO Ethernet client module handles the radio connection for a maximum of eight connected devices with Ethernet interface. If one of the connected devices is exchanged, the Ethernet client module recognizes this immediately and administers the new address.

	SIMATIC PCS 7 allows you to integrate mobile or stationary
	remote clients into the OS-LAN (terminal bus) via a SCALANCE
9	W788-1PRO access point.
	The following applications can be implemented in this manner:
	• Use of additional remote OS clients (1 or 2 on IWLAN)
	• Linking of Web clients to a SIMATIC PCS 7 Web server (1 or
	2 on IWLAN)
	• Remote access to an engineering station with application of
	Remote Desktop (Windows XP or Server 2003 operating sys-
	tem) or PC Anywhere, e.g. during commissioning
	Mobile remote clients (e.g. notebooks) possessing a WLAN in-
	terface can communicate with the access point via it. Stationary
	remote clients in a desktop/tower housing (SIMATIC PCS 7 In-
	dustrial Workstations) require a SCALANCE W746-1PRO Ether-
	net client module for the IWLAN communication with the access
	point.
	SCALANCE W746-1PRO Ethernet client module and
	SCALANCE W788-1PRO access point are both very rugged,
	use state-of-the-art authentication and encryption procedures,
	and guarantee high reliability of the radio channel.
	Note:
	Please note that Industrial Wireless LAN is not approved of as a terminal
	bus (OS-LAN) or plant bus of SIMATIC PCS 7.

Special features of the SCALANCE W746-1PRO Ethernet client module

•Versatile power supply facilities (operation on 100 V to 240 V AC network with PS791-1PRO power supply)

•Antenna diversity for reliable reception in complex radio envi- ronments with two ANT795-4MR omnidirectional antennas screwed onto the housing, can be replaced by other types from the SCALANCE W700 range

•Transmission rate up to 54 Mbit/s at 2.4 GHz and 5 GHz with radio approval in more than 30 countries

•Conforms to the IEEE 802.11b/g and IEEE 802.11a standards

•High reliability through reservation of data transfer rate with IWLAN communication with SCALANCE W788-1PRO access point

•WPA and 128-bit encryption (AES) for high security against il- legal access

•Rugged metal enclosure resistant to shock and vibration, and with IP65 dust protection

•Suitable for ambient temperatures from -20 to +60°C (resistant to condensation)
