Simatic ET 200pro IWLAN (photo) is the first distributed I/O system from this firm that communicates via Industrial Wireless LAN (IWLAN). For this purpose, the new 154-6 PN HF IWLAN interface module was developed for the Simatic ET 200pro system. The interface module wirelessly integrates the distributed I/O system into the automation network, and is designed for harsh industrial environments with a high degree of protection (IP65/66/67). Typical applications include overhead monorail conveyors, automatic guided vehicles and warehouse logistics. The interface module works according to the WLAN standards IEEE 802.11 a/b/g/h, and therefore operates in the 2.4 and 5 GHz frequency bands. — Siemens Industry Automation Division, Nuremberg, Germany
