November 19, 2013--Siemens introduces Scalance modules for applications of wireless data transmission in cabinets and in equipment at the field level.
With the compact Scalance W761-1 RJ45 access point and the Scalance W721-1 RJ45 client module, users can implement wireless machine networking out of the cabinet, with cost and space savings, for example, in conjunction with the Simatic ET 200SP distributed I/Os. The components are designed with degree of protection IP20 and support transmission rates of up to 150 Mbit/s.
The Scalance W774-1 RJ45 access point and the Scalance W734-1 RJ45 client module are designed for transmission rates up to 300 Mbit/s. These devices are enclosed in a compact and robust aluminum housing, provide a slot for the Key-Plug W700 iFeatures swap medium and support Power-over-Ethernet (PoE). Additional functions, known as iFeatures, such as iPCF, can be activated via key-plug in a later delivery stage. The design, based on Simatic S7-1500, permits fast and flush installation directly adjacent to the new Siemens controls or the powerful Simatic ET 200MP distributed I/Os.
Siemens also offers a WLAN controller, with which wide radio coverage can be achieved with up to 96 controller-based access points. The offering is rounded off by a comprehensive portfolio of antennas. The MIMO antenna technology (Multiple Input Multiple Output) according to the IEEE 802.11n standard that is used provides a high level of data transmission reliability. Industrial wireless networks are used both indoors and outdoors and in harsh environments.
Typical applications include high-bay warehouses and transportation systems in internal logistics, assembly-line production, mobile equipment such as cranes or amusement park rides, and railroad applications.
