© Siemens AG 2007 Communication Industrial Ethernet Industrial Wireless LAN (IWLAN) ■ Overview ■ Design SCALANCE W746-1PRO Ethernet client module OS clients SCALANCE X414-3 PCS 7 Web server OS-LAN (terminal bus) SCALANCE X204-2/X208 Redundant OS server Engineering station Access point SCALANCE W788-1PRO Mobile remote client with WLAN interface 9 Ethernet Client module SCALANCE W746-1PRO Stationary remote client SIMATIC PCS 7 allows you to integrate mobile or stationary remote clients into the OS-LAN (terminal bus) via a SCALANCE 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 system) or PC Anywhere, e.g. during commissioning Mobile remote clients (e.g. notebooks) possessing a WLAN interface can communicate with the access point via it. Stationary remote clients in a desktop/tower housing (SIMATIC PCS 7 Industrial Workstations) require a SCALANCE W746-1PRO Ethernet 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. 9/30 Siemens ST PCS 7 · November 2007 The SCALANCE W746-1PRO Ethernet client module is highly suitable for integrating devices with an Industrial Ethernet connection 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. 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 environments 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 illegal 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) For further information and detailed technical specifications, refer to Catalog IK PI, the A&D Mall or Catalog CA 01 under "Communication/networks, SIMATIC NET communication systems, Industrial mobile communication".
