Abstract: A system and a method are provided for monitoring an exhaust gas purification system that is functionally connected to an emission source. An emission sensor acquires an emission signal that indicates emissions of the emission source on the exiting from the exhaust gas purification system. In addition, measurement signals that are each related to the exhaust gas purification system are acquired by a plurality of further sensors. A process state of the exhaust gas purification system is determined based on the measurement signals of the further sensors. Then, the emission signal and the process state are assessed with respect to an anomaly in each case.

Abstract: The invention relates to a method of offline instrument simulation of a field instrument, wherein at least one parameter of the field instrument is visualized and a parameterization of the field instrument is made possible and the instrument simulation is generated on the basis of an instrument description file, and wherein the instrument simulation is performed in a browser.
