<p>PROBLEM TO BE SOLVED: To facilitate operation for display on a display means by performing arithmetic operation according to a predetermined arithmetic expression by using the arithmetic result of a processing means which controls a load. SOLUTION: For example, a program which controls a load such as a fuel injection valve 4 of a vehicle internal combustion engine 1 driving an automobile is stored in a program memory M1. Process means 6 and 14 execute the program to control the operation of the load and the control state of the controlled load, e.g. the output of a sensor for the air suction pressure, air suction temperature, etc., of the internal combustion engine 1 and arithmetic results including the fuel injection amount of the fuel injection valve 4 obtained by operation are displayed by a visual display means 13. Specially, the arithmetic expression using the arithmetic results is set by an arithmetic expression setting means and the arithmetic results of the processing means are set by an arithmetic result read means to read the arithmetic results out of the process means. An arithmetic means performs operation based upon the arithmetic expression and arithmetic results to be displayed which are selected by a selecting means are displayed.</p> |
