Title: EXPANDING FUNCTIONS OF A PROCESS DEVICE
Abstract:
A board-level assembly (114) that is useful to expand functions of a valve positioner (100) on a valve assembly (102). The board-level assembly (114) can incorporate a main circuit board (116) and a smart circuit board (118). The main circuit board (116) may be configured to communicate with the smart circuit board (118), find a storage memory (160) on the smart circuit board (118), retrieve data from the storage memory (160), and use the data to configure functions on the main circuit board (116). In one implementation, the smart circuit board (118) can release and engage the main circuit board (116). This configuration can allow different configurations of the smart circuit board (118) to swap into the board-level assembly (114), each of the different configurations providing data the main circuit board (116) can exploit to change the functions of the valve positioner (100).
