Industrial Wireless Communications Industrial use of radio technology requires particularly reliable connections. A solid basis therefore is provided by the universal standard IEEE 802.11. Interference-tolerant modulation is taken into account. In order to maintain a radio link even over long distances or in the event of reflection against metal objects, the data rate is reduced in defined increments. These are all components of the IEEE 802.11. However, the requirements for data communication in the industrial area is outside the normal scope. The devices in the SCALANCE W family compliment the universal WLAN Standard IEEE 802.11 with additional features, that justify the ‘I’ in IWLAN. For example IWLAN components from Siemens which makes a defined data rate available to selected clients. IWLAN offers deterministic data traffic based on the shared WLAN medium. IWLAN supports the focused monitoring of a client's connection to the access point so that countermeasures can be initiated the moment the connection is broken or the radio cell exited.
Network Components - SCALANCE W The products of SCALANCE W offer the unique combination of reliability, ruggedness and security in one product. High availability and reliable radio communication for productive operation in the plant thanks to the dedicated bandwidth and the cyclic monitoring of the connection to the clients Rugged IP 65 protection, for temperatures of between -20°C with moisture condensation and +60°C, and satisfy stringent demands regarding vibration and shock resistance High data security to protect against hackers and operator faults thanks to the latest security mechanisms such as WPA (WiFi Protected Access) and 128-bit encryption with AES (Advanced Encryption Standard) Easy to install with a flexible single line energy supply for data and power by means of Power-over-Ethernet (PoE) in accordance with IEEE 802.3af, even at 24 VDC. Simple and rapid configuration using the installation wizard. Easy replacement of device in fault scenarios by means of C-PLUG (Configuration Plug) Access Points - SCALANCE W-780 The access points serve to establish radio networks in accordance with IEEE 802.11a/b/g/h up to 54 Mbit/s, at both 2.4 GHz as well as at 5 GHz. Ranges of up to 30 m indoors (100 m outdoors). Industrial Wireless LAN functionality can easily be added to existing LAN and WLAN networks be means of SCALANCE W-780 access points. Client Modules - SCALANCE W-740 The client modules serve as a radio interface between a client with as Industrial Ethernet interface, for example S7-300 with CP343-1 or ET200pro, and the radio network in accordance with IEEE 802.11a/b/g/h up to 54 Mbit/s, both at 2.4 GHz as well as at 5 GHz. Connections can be established with up to 8 IP devices.
Communications processors - CP 7515 The CP 7515 is a PC card (32 bit CardBus) for operation on an Industrial Wireless LAN (IWLAN) radio network with reliable communication. It is designed to be used used with a SIMATIC Field PG or a Notebook PC. The CP 7515 can be used in a standard WLAN according to IEEE 802.11b/g and IEEE 802.11a at 2.4 GHz or 5 GHz. Two Integrated antennae (for antennae diversity) for reliable reception in areas that place high demands on radio communication. Two devices in one: can operate at 2.4 GHz or 5 GHz High degree of protection against unauthorized access thanks to WPA and 128-bit encoding (AES) Investment protection through recognized worldwide industry standard IEEE 802.11 Communication Processor - CP 1515 The CP1515 is a Type II PCMCIA card (16 bit) and can be used on MOBIC. It operates at 2.4 GHz with 11 Mbit/s (IEEE 802.11b)
Mobile Industrial Communicator - MOBIC T8 MOBIC T8 - the Mobile Industrial Communicator is an industrial-strength, only 1,7 kg weighty Internet Pad which enables local or worldwide access to an intranet or the Internet. Mobile means it can use pluggable PCMCIA-radio cards, like wireless LAN (IEEE802.11b) for local access or GSM/HSCSD for global use over normal period of operation of 8 hours use without recharging battery. Industrial strength means it is especially rugged, splash-proof, and dust-resistant. Vibration protected up to an acceleration of 150m/s 2 and drop height 2 meters to MIL standard 810. MOBIC provides security for your use. MOBIC is also certified of course according to FM class 1 division 2, CE, UL, CSA and e1- for installing the MOBIC in vehicles with a MOBIC charging station. It is ergonomically designed, with 8.4" color touch display operated with either pen or fingertip and with additional function keys on the right-hand side. The high resolution (SVGA 800x600 pixel) TFT-display ensures the easy clearness of display in case of insufficient light.
