ABSTRACT:
An apparatus and method for controlling the operation of a system are provided. The overall system operation is described by a plurality of mechanism cycles of operation each defined by a sequence of instructions relating sensed conditions of input devices, selectable conditions of output devices and variable values. Instruction signals representing the instructions of the sequences are stored together with mechanism cycle status signals each representing the executability of the associated mechanism cycle. Only instructions associated with cycles for which the status signal represent an executable condition are executed. Instructions for cycles for which the status signals represent a nonexecutable condition are modifiable during execution of the other instruction sequence. The instruction signals include variable name signals associated with unique interface circuits connected to the input and output devices. The assignment of interface circuits to variable names is accomplished independently of the basic program generation and reassignment is accommodated during cycle execution irrespective of the condition represented by the status signal.
