    Abstract: A method includes identifying a plurality of elements in a process control system that uses a process value from a field device. The method also includes identifying an aggregate control connection status of the field device by (i) determining whether one or more of the elements can use a manual value in place of the process value, (ii) determining whether one or more other elements in the plurality can use a user configured value, and (iii) evaluating a logic expression based on results of the determining in (i) and (ii). The method further includes determining whether the field device is available to be taken offline based on the aggregate control connection status. In addition, the method includes generating a notification based on the determination of whether the field device is available to be taken offline.
