摘要
A system includes a server configured to generate a request for status information and/or diagnostic information associated with a field device in a process control system. The system also includes an interface component having (i) an emulator configured to emulate a device manager associated with the field device and (ii) a communication manager configured to communicate with the field device over a communication link using a specified protocol. The server is configured to provide the request to the communication manager through the emulator, receive the status information and/or the diagnostic information from the field device through the communication manager and the emulator, and generate a user interface based on the status information and/or the diagnostic information. The communication manager could represent a communication Device Type Manager (DTM), and the emulator could emulate at least some functions of a device DTM.
