Wireless device and method for setting the same, sensor unit and wireless unit,

Abstract

The invention provides a wireless device and a method for setting the same, a sensor unit and a wireless unit. The wireless device includes a sensor unit and a wireless unit. The sensor unit includes an input / output unit for measuring or manipulating a state quantity in a process; a first local communication unit for performing local communication to transmit / receive measurement results or manipulation commands for the input / output unit; and a first supply unit for supplying power to the input / output unit and the first local communication unit. The wireless unit may include: a wireless communication unit configured to transmit / receive the measurement results or the manipulation commands for the input / output unit; a second local communication unit configured to perform local communication with the first local communication unit to transmit / receive the measurement results or the manipulation commands for the input / output unit; and a second supply unit configured to supply power to the wireless communication unit and the second local communication unit.

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that the input / output unit cannot measure and manipulate state quantities (ie, it goes offline) when the battery is replaced

[0014] (3) The battery cannot be replaced while the factory is running

With the latter method, there is a problem that a considerable amount of time and cost are required since the wireless field device must be removed and then reinstalled
