PROGRAM TEST METHOD OF DIGITAL CONTROLLER

摘要

PURPOSE:To confirm easily a range of variation when a program is changed by designating a terminal at an input/output data part of an arithmetic module and selecting and displaying the terminals of other arithmetic modules connected to the terminal of the input/output data part with reference to a connection table. CONSTITUTION:An operator designates a terminal number of an output data part of an arithmetic module to be changed and then pushes a 18. Then a terminal of an input data of an arithmetic module to which the designated terminal of the output data part is selected with reference to a connection table within a main memory 3 in the form of the processing of the device 18. These selected terminal numbers are displayed to a CRT display device 19. Thus it is possible to confirm easily the range of variation and the effect when a program is changed.
