Abstract:
1. A field mountable dedicated process diagnostic device coupled to a process control loop for use in diagnosing operation of an industrial control or monitoring system of an industrial process, comprising: an input configured to receive at least one process signal related to operation of the industrial process from a diagnostic sensor; a memory in the field mountable dedicated process diagnostic device containing diagnostic program instructions configured to implement a plurality of diagnostic algorithms, using the at least one process signal and wherein the at least one of the plurality of diagnostic algorithms is specific to the industrial process wherein the plurality of diagnostic algorithms include at least two diagnostic algorithms each of which are specific to different industrial processes; a selection input configured to receive diagnostic algorithm selection data indicative of a type of the industrial process and which identifies one of the at least two diagnostic algorithms and thereby selects a diagnostic algorithm; and a microprocessor configured to perform the diagnostic program instructions and responsively diagnose operation of the industrial process based upon the at least one process signal and the selected diagnostic algorithm.
