Abstract: A method for anomaly detection in process control environments is provided. The method includes receiving a first information from first field devices located within a process control environment, and transmitting a first vector based on the first information, to a first detector implemented within an edge node that provides gateway access to the environment. The first detector implements a first classifier model. When the first detector detects an anomaly event based on the first vector, a second vector is transmitted to a second detector implemented within a cloud based server. The second vector, different from the first vector, is generated based on second information from second field devices located within the process control environment. The second detector implements a second classifier model different from the first classifier model. An anomaly event alert is generated when one of the first detector and the second detector detects an anomaly event.

Abstract: A tag identification device automatically identifies a correspondence relationship between a tag name arbitrarily set by a user and a process value. The tag identification device includes a processor, in a first process, that obtains first definition information in which the tag name, a type of tag data which is handled using the tag name, an upper limit value, an lower limit value, and an engineering unit are defined for each tag. The processor extracts, from the first definition information, a tag coinciding with at least one of the type of tag, the upper limit value, the lower limit value, and the engineering unit of a predetermined first process value. The processor selects the tag data handled using the tag name defined for the extracted tag, using an actual measurement value of the tag data. The processor identifies the selected tag data as the first process value.
