The Siemens Simatic ET 200pro IWLAN from Siemens Industry Inc. saves significant communication cabling and installation costs by delivering wireless connectivity from any distributed I/O station, the company says. Compatible with Siemens line of ET 200pro I/O and specialty modules, the rugged IP67-rated IWLAN interface can be directly mounted on a machine, eliminating the need for installation inside an electrical enclosure, the company says. Based on IEEE 802.11 WLAN standards, the ET 200pro’s wireless design supports deterministic iPCF (Industrial Point Coordination Function) for critical industrial Ethernet communications using standard Profinet protocol. The ET 200pro IWLAN includes a complete wireless network interface with removable antenna interface unit, standard ET 200pro connection unit for adding modular I/O devices, diagnostic LEDs and a built-in Ethernet port for local programming or network trouble shooting. An industry standard 7/8 inch plug-in connector provides the power connection and each ET 200pro station can be vertically or horizontally installed without restrictions. Optional antennas including omni-directional antennas are available for direct or remote mounting and higher gain signal transmission over longer distances or through obstructions. Wireless radio frequency is selectable for either standard 2.4 GHz or 5 GHz and includes support for IEEE 802.11 a/b/g/h/e/i transmission standards. The maximum wireless data transmission rate is 54 Mbits/s with a typical send cycle time of 32 ms.

Each device includes a built-in Web server with HTML pages for editing configurations, setting security access and viewing important diagnostic information.
