Systems and methods for write protecting foundation fieldbus linking devices

摘要

Systems (100) and methods (700) for write protecting Foundation Fieldbus linking devices (115) are described. A message output by an external system (125) for communication to a Foundation Fieldbus linking device (115) may be received (705) by a gateway device (105). The linking device (115) may be identified by a virtual address included in the received message. The gateway device (105) may determine (715) whether the message includes a command to write data to the linking device (115) or a Foundation Fieldbus device (120) connected to the linking device (115). If it is determined that the message does not include a command to write data, then the gateway device (105) may direct (725) communication of the message to the linking device (115). If, however, it is determined that the message includes a command to write data, the gateway device (105) may generate (720) an exception for preventing the requested write operation.
