The present method is a method to automate the repeatable process of application engineering microprocessor based control systems and creating the related documentation to submit for engineer approval and construct the control system. Prior to this method engineering every decision about point assignment, part selection, controller addressing et al was either made and only recorded upon the engineering documents or made in the field and either recorded manually or not at all. As the result when those engineering decisions were required elsewhere in the engineering documents individuals could only refer to those documents when retabulating the information. The present method allows a user to record all most all of the engineering decisions in a soft environment allowing the decisions to be repeatably used in every engineer document. As the result efficiency in the task of application engineering is increased and errors created as information is transferred are eliminated.
