WIRELESS DEVICE FOR CAPTURING STRANDED DATA ON FIELD DEVICES

摘要

A method includes coupling an adapter device to a field instrument in an industrial control system to provide a wireless communication capability to the field instrument. The method also includes connecting a first wire and a second wire of the adapter device to a positive wire of a current loop connected to a positive terminal of a communication module of the field instrument. The method also includes connecting a third wire and a fourth wire of the adapter device to a negative wire of the current loop connected to a negative terminal of the communication module of the field instrument. The method also includes disconnecting the positive wire of the current loop between the first wire and the second wire and the negative wire of the current loop between the third wire and fourth wire.
