This paper proposes a modification to the dynamic causal digraph (DCDG) method in order to address the detection and isolation of oscillations in a process. The proposed detection method takes advantage of the properties of residual signals generated by the DCDG method by studying their zerocrossings. The method is tested in an application to a board making process and the results are presented and discussed.
