Abstract
Abstract A system and method for addressing a plurality of field points having a group address and a point address including a group register for storing the group address of a selected field point and having counting means included therein for changing the stored group address, a point register for storing the point address of the selected field point and having counting means included therein for changing the stored point address, a field point selection input for entering the group and point addresses for the selected field point, and address changing inputs including an input for changing the stored group address in either a forward or backward manner without changing the stored point address, and an input for changing the stored point address in either a forward or backward manner without changing the stored group address.
