ABSTRACT:
An elevator control utilizing a data processor and which is sequentially responsive to independent program blocks. The control includes a central processing unit, programed read only memory and random access memory, with input and output circuits for interconnection between the control, the elevator, elevator drive and the structure in which the elevator operates. The memory has a capacity to store information for elevator systems and structures with a wide variety of parameters. Specific addresses in the memory are assigned for the input information and for elements of status information which provide for interaction between different portions of the program. The assigned addresses are common to all elevator controls, enabling use of standard program blocks and minimizing the original design work required for each control.
