Comunicación inalámbrica Profinet mediante el uso de equipos SCALANCE

Abstract

This article describes the development of a Wireless Profinet communication link. Using a SCALANCE W746 1-PRO client module, which requested the communication every 16ms through a 5 GHz carrier frequency, the data was transferred from a SCALANCE W788 1-PRO access point located 50 meters away from the client; this was posible due to the Siemens ANT795 4-MR omnidirectional antenas. The connection status was checked through a network analysis and it was corroborated that there is indeed a successful communication. Its application is considered scalable for large networks, providing significant savings in the use of cable which in turn leads to economic savings. In addition, it’s possible to configure a roaming service, allowing the client module to use a network coverage different from the main one, which translates into free movement.
