Abstract
A computer system for generating a cause effect matrix as a user interface to develop a control program based on the cause effect matrix and to compile and download the resulting program into a programmable controller. A cause effect matrix diagram is used to develop a function block diagram program which is a standard IEC 1131-3 language. The function block diagram is translated into structured text which is compiled into intermediate code. The intermediate code is translated into the native code for the micro-processor of the target control system, including but not necessarily limited to the Motorola processor MPC-860. The automation of a cause effect matrix diagram to generate a function block diagram permits additional capability by allowing functions for causes, intersections, and effects. Because special functions may be included, the results of a cause generate timing functions or other computations before initiating the effect.
