Apparatus and method for integrating wireless field devices with a wired protocol in a process control system
An apparatus is provided for facilitating integration of a wireless field device (such as a wireless sensor or actuator) and a wired protocol that is used in a process control system. The apparatus supports a wireless field device protocol for communicating with the wireless field device. The apparatus also supports a wired field device protocol for communicating with other components of the process control system over a network. The apparatus could map a wireless application model associated with the wireless field device protocol to a wired application model associated with the wired field device protocol. The apparatus could actually support multiple mappings from the wireless application model to wired application models associated with multiple wired field device protocols. As particular examples, the wired field device protocol(s) could include the HART, Foundation Fieldbus, Profibus, and/or Modbus protocols. The network could represent an Ethernet network or a serial network.
