Abstract
The controller system includes a control logic device and a controller arranged between a processor and the control logic device. The control logic device includes a stored initiation value for initiating a task activated by the control logic device, a device for making a comparison between the stored initiation value residing in the control logic device and an incrementally changing time value and a device for initiating the task when the stored initiation value therein corresponds to the incrementally changing time value. The controller advantageously includes a device for making a comparison of the new initiation value transferred from the processor, the stored initiation value and the time value with each other to obtain additional information; a device for transferring the new initiation value to the control logic device for storage as the stored initiation value after the comparison in the controller and a device for transmitting the additional information to the control logic device according to results of the comparison in the controller.
