In an individual section (IS) glassware forming system (10) that includes a plurality of operating mechanisms for performing cyclic motions, an electronic controller (52, 64) for controlling cyclic motion of at least one (20a) of the operating mechanisms includes an electronic memory (66) for storing a plurality of motion profiles (FIGS. 4C and 5C) for the one operating mechanism, with each of the profiles comprising a set of motion data versus time data. Each of the profiles has a piecewise linear contour determined by a plurality of control points (A to R5), with each of the control points having associated motion and time data values. The operator may selectively display one of the profiles as a table of time values for the control points, with the time values preferably being in units of IS machine degrees. The operator may change the time values associated with one or more of the control points, and the controller automatically recomputes the motion data versus time data for the entire profile as a function of a change in time data by the operator at at least one of the control points, while maintaining the piecewise linear contour of the overall profile. Operation of the operating mechanism is thereafter controlled as a function of the recomputed motion versus time profile data.
