Distributed IOs communicate wirelessly for the first time

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. It is designed for harsh industrial environments with a high degree of protection (IP65/66/67) and conceived for use directly on the machine.

Typical application areas where this is advantageous include overhead monorail conveyors, automatic guided vehicles, and warehouse logistics. The user can choose expansion modules for Simatic ET 200pro IWLAN as usual from the range of Simatic ET 200pro modules.

The new interface module is integrated in the communication network as an IWLAN client via an IWLAN access point, such as the Scalance W access point from Siemens. The 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.

It also supports the important industrial functions iPCF (Industrial Point Coordination Function) for deterministic WLAN communication and rapid roaming as well as standard and safety-oriented applications via Profinet. A web server is integrated for user-friendly basic and security settings of the device.
