Method for monitoring an automation system

A method for monitoring an automation system (500) having a multiplicity of field devices (101-105) which are arranged in a spatially distributed fashion and are each configured to acquire and/or seta primary process variable (F, p, T, R, D) that is dependent on the process, and are also configured to each acquire at least one secondary environmental variable (201-205), and having at least one superordinate process control unit (300) for controlling the process, wherein the method involves at least the following steps: - transmitting the acquired environmental variables (201-205) to a superordinate database and analysis platform (400); - monitoring the automation system (500) by means of the database and analysis platform (400), wherein in order to monitor the automation system (500), thedatabase and analysis platform (400) compares the acquired transmitted secondary environmental variables (201-205) with comparative environmental variables (211-215) which represent a usual state ofthe automation system (500)
