摘要： Method and apparatus for sustaining process temperature measurement with respect to a lead wire break. A resistance temperature device can include a group of lead wire arms including lead wire arms of a first lead wire type and a second lead wire type. An operation can occur to automatically switch from a first lead wire type configuration to a second lead wire type configuration in the resistance temperature device having the plurality of lead wire arms including the first lead wire type and the second lead wire type, if one or more wire breaks occurs in one or more the lead wire arms.

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.
