A method implemented by a monitoring device for monitoring a current loop, the method comprising: intercepting (102) a command circulating on the current loop according to a HART protocol; extracting (104), from the command, first data indicating whether the command is transmitted by a master station in the meaning of the HART protocol and second data indicating the type of the command; and generating (106) or not generating an alarm from the extracted data, the alarm indicating a potential anomaly and/or hazard of the command. 一种由监控设备实现的用于监控电流回路的方法，所述方法包括：拦截(102)在电流回路上循环的根据HART协议的命令；从所述命令中提取(104)指示所述命令是否由HART协议意义上的主主站发送的第一数据和指示所述命令的类型的第二数据；以及根据所提取的数据生成(106)或不生成警报，所述警报指示所述命令潜在异常和/或危险。
