Abstract
An apparatus having a programmable processor and a memory for performing a plurality of user-selectable control functions includes a database for storing a plurality of items associated with each of the control functions. The items include, for each function, at least one procedure for performing an action associated with the control function and a specification of at least one state associated with the control function. The apparatus further includes software routines stored on the memory and adapted to be executed by the processor that facilitate selection of a procedure in the database, that access the database and cause performance of the selected procedure to achieve the state specified therein, and that monitor at least one resource associated with the action of the procedure and, based thereon, determine whether the specified state has been achieved.
