Procedure designed to monitor an automation system used in automation engineering, wherein said procedure is designed to perform a process, wherein the automation system comprises at least the following elements: - several field devices that are distributed around the automation system and that each have at least a sensor or actuator element and at least an environmental sensor element, wherein the at least one sensor or actuator element is designed to measure and/or set a process-dependent primary process variable (F, p, T, R, D) and wherein the at least one environmental sensor element is designed to measure a secondary environmental variable, - at least a higher-level process control unit to control the process, wherein, to control the process, the process control unit is in connection with the several field devices in a manner that transmits data in such a way that at least the primary process variable (F, p, T, R, D) can be communicated between the process control unit and the several field devices in order to control the process, wherein said procedure comprises at least the following steps: - Transmission of the measured secondary environmental variables, wherein the measured environmental variable is transmitted by at least some of the several field devices to a higher-level database and analysis platform, particularly a cloud computing-based platform; - Monitoring of the automation system by the database and analysis platform, wherein, for the purpose of monitoring the automation system, the database and analysis platform compares the measured and transmitted secondary environmental variables with the environmental comparative variables that represent a normal condition of the automation system in order to detect an unusual condition in the automation system. - several field devices that are distributed around the automation system and that each have at least a sensor or actuator element and at least an environmental sensor element, wherein the at least one sensor or actuator element is designed to measure and/or set a process-dependent primary process variable (F, p, T, R, D) and wherein the at least one environmental sensor element is designed to measure a secondary environmental variable, - at least a higher-level process control unit to control the process, wherein, to control the process, the process control unit is in connection with the several field devices in a manner that transmits data in such a way that at least the primary process variable (F, p, T, R, D) can be communicated between the process control unit and the several field devices in order to control the process, - Transmission of the measured secondary environmental variables, wherein the measured environmental variable is transmitted by at least some of the several field devices to a higher-level database and analysis platform, particularly a cloud computing-based platform; - Monitoring of the automation system by the database and analysis platform, wherein, for the purpose of monitoring the automation system, the database and analysis platform compares the measured and transmitted secondary environmental variables with the environmental comparative variables that represent a normal condition of the automation system in order to detect an unusual condition in the automation system.
