Abstract
A sequence controller for an automatic grinding machine or the like for controlling a sequence of machine functions and for providing a display of digital information which explicitly directs an operator through manual or semi-manual functions and which also provides diagnostic information. Diagnostic information is displayed on two levels, the first level is defined as 'input code' which represents signals generated by a programmable controller to define the machine requirements due at any given time. These signals are normally compared with 'requirements met' signals from input devices to determine whether or not the sequence should be advanced. The second level of signals are termed 'cycle step commands' which represent signals sequentially generated in the controller to actuate specific machine functions. The controller may advance sequentially or non-sequentially. Circuit boards are correlated in physical location to cycle step command codes.
