 SureCross™ Wireless Network—Rotary Table
Application In a number of automotive manufacturing processes, rotary tables are used for indexing parts into various automatic and manual work stations. In many cases, it is necessary to use sensors to verify that parts are present, properly placed or correctly processed before indexing. Historically, the solution of using slip rings to allow sensor power and signals to be hardwired to the control system has often proven to be costly and unreliable. An alternative solution of allowing more sensor signals to be processed while increasing the reliability is also beneficial in many applications. Solution Banner’s SureCross™ wireless network is designed specifically to operate in concert with sensor technology (analog and discrete) in an industrial environment (IP67 enclosure rating). The system consists of a Gateway which communicates with up to 15 Nodes using Frequency Hopping Spread Spectrum (FHSS) and Time Division Multiple Access (TDMA) methodologies, creating a very robust protocol for the factory floor. Multiple Gateways can be added to increase the potential number of Nodes in a system.  In this example, four Banner part-presence sensors are connected to a Node powered by a FlexPower™ battery module. The lifetime of a battery is dependent on several factors including the number and type of sensor, sample rate and cycle time, and can last for years in some cases. Sensor signals are transmitted from the Node to the Gateway, which has four corresponding digital outputs connected to the control PLC.
With SureCross™, Banner’s comprehensive sensor capabilities are extended through wireless connectivity, often to locations and applications never before possible. Learn more about how SureCross can solve the most challenging applications . |
