摘要： An asset tracking system for use in a process control environment may include one or more asset tracking devices and an asset tracking host. The asset tracking device may receive signals corresponding to a position or location of an asset to be tracked, and may communicate, using an industrial automation protocol such as wireless HART, an indication of the position to the asset tracking host. The signals may be GPS signals that are re-radiated into the process control environment. Other information, such as environmental data, may be communicated in conjunction with the position of the asset. The asset tracking host may store and/or display the data or information included in the message, and may send a different message to the asset tracking device. An asset tracking device may be included in a field device, a network device, or a portable communications device used in the process control environment.

摘要： An interface module is operatively coupled to a Fieldbus process control network and a Modbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a register map database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to register numbers of the Modbus process control network. Once the Fieldbus process control parameters are mapped to the Modbus registers, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the register map database.

摘要： An industrial field device provides information indicative of a process variable. The field device includes a controller, communication circuitry, a process variable sensor and measurement circuitry. The communication circuitry is coupled to the controller. The process variable sensor has an electrical characteristic that changes based on a variable of a process fluid. The measurement circuitry is coupled to the process variable sensor and coupled to the controller. The controller is configured to generate communication via the communication circuitry relative to the process variable, and to provide an indication of sand flow or other solids in the fluid.

摘要： An electrically variable optical attenuator and associated methods are disclosed. In one aspect, the attenuator includes at least one sensor that provides a sensor output with respect to a variable that affects attenuation. Methods of characterizing the attenuator include obtaining a set of attenuation/sensed variable data, and generating a relationship (such as a look-up table or mathematical function) relating the sensed variable to the attenuation.
