    • A handheld communicator wirelessly interfaces or communicates with individual devices in a process control system, such as field devices, controllers, etc., to wirelessly perform monitoring, maintenance, configuration and control activities with respect to those devices. The wireless handheld communicator includes a housing adapted for handheld operation, a processing unit disposed within the housing, a computer readable memory disposed within the housing and coupled to the processing unit and a display, a keypad and a radio frequency transceiver. The handheld communicator may be adapted to communicate with a host system to receive information needed to communicate with various field devices in the process plant and may then be used to wirelessly communicate with each of the various field devices directly while in close proximity to the field devices to perform monitoring and configuration activities with respect to the field devices. Thereafter, information obtained from the field devices may be wirelessly communicated to the host system or to a repository, such as a data historian or a configuration database.
    • 手持式通信器与诸如现场设备,控制器等的过程控制系统中的各个设备无线地接口或通信,以无线地执行关于这些设备的监视,维护,配置和控制活动。 无线手持通信器包括适于手持操作的外壳,设置在外壳内的处理单元,设置在外壳内并耦合到处理单元的计算机可读存储器,以及显示器,小键盘和射频收发器。 手持式通信器可以适于与主机系统进行通信,以接收与过程工厂中的各种现场设备进行通信所需的信息,然后可以用于与各种现场设备中的每一个直接通信,同时紧邻现场设备 对现场设备执行监控和配置活动。 此后,从现场设备获得的信息可以无线地传送到主机系统或存储库,诸如数据历史记录器或配置数据库。
