    摘要: Systems, methods, and apparatus for facilitating communications between an external controller and Fieldbus devices are described. A primary linking device in communication with the controller and one or more Fieldbus devices may be configured to direct the communication of a timing message to the controller and determine whether a response to the timing message has been received from the controller. Based upon the determination, the primary linking device may direct a switching of communications control to a secondary linking device.
