Methods for determining the existence and the source of instability in a mesh of process control, and system for determining the existence of, or a source of.An instability in a mesh of process control.A method and apparatus determine the presence, and the source of instabilities such as limit cycles.In a mesh while the mesh process control process control operates online in a process environment.The method and apparatus for measuring one or more signals within a network of process control, process control, when the mesh is connected in line in a process control environment.Store the signal measured as data signal and then performs one or more statistical analyses on the data of the stored signal to determine if there are instabilities and, if positive,If the source of instability is within a mesh servant or out of a mesh servant, and if it is due to friction, external forces, or mechanical abnormalities.
