Abstract
A system and process for generating a control program for execution by a programmable logic control unit including the steps of: providing a variable editing user interface allowing a user to define and edit variables including input variables and output variables; providing a program level editing user interface allowing the user to edit a program level; providing a state editing user interface allowing a user to define and edit a plurality of states of the control program; providing a condition editing user interface allowing a user to define and edit at least one condition for each of the states of the control program; and generating the control program as a function of associative relationships of the variables, states, and conditions.
