ABSTRACT:
A programmable automatic controller for operating machines having a plurality of components which operate in a timed or sequential relationship with one another. The controller includes a timing means for generating cycle clock pulses in synchronism with the operation of the machine, wherein the cycle clock pulses provide an instantaneous indication of the time elapsed in each cycle of operation of the machine. A COM/MOS running storage means stores the relative times during each cycle of machine operation when each of the plurality of machine components are to be enabled and/or inhibited. When the time elapsed in a cycle corresponds to a component actuating time stored in the running storage, an actuating signal is generated by a comparator. This signal is coupled to a machine component addressing arrangement which provides a component enable or inhibit command signal to the addressed component whose actuating time compared to the cycle time lapsed. Accordingly, in a cycle of operation a plurality of component operating command signals are generated which command the respective machine components to initiate and terminate operation at preselected time intervals.
An up-down counter is provided for selectively varying the component machine actuating times stored in the running means while the machine is in operation. In addition, means are provided for initiating a machine starting or stopping sequence at any time during the machine cycle. The machine starting and stopping sequences are predetermined and can be varied at any time before the operation of the machine.
