Abstract
A programming interface for a control system comprises a display region that provides a representation of a plurality of output cam profiles. The representation provides information concerning latch/unlatch operations of a plurality of cam elements that control on/off states of a plurality of output devices and that form the plurality of output cam profiles.
Claims21
A control system, comprising:
- a processor that executes computer executable instructions to generate a plurality of output cam profiles that define latch and unlatch operations for a plurality of cam elements that control on operations and off operations of a plurality of output devices;
- and
- a programming interface, comprising:
- a first display region that provides a graphical representation of the plurality of output cam profiles, comprising a plurality of views of the plurality of output cam profiles, including:
- a first view, wherein the first view provides a graphical representation of the plurality of output cam profiles, wherein the graphical representation displays the latch and unlatch operations for the plurality of output cam profiles as line graphs ordered by output bit which changes state based on a selected latch condition and depicts the latch and unlatch operations as rising and falling edges of a line graph corresponding to the latch and unlatch operations of individual cam elements as a function of position or time;
- and
- a second display region that provides a tabular representation of the plurality of output cam profiles, wherein the tabular representation displays a grid of data values associated with the plurality of cam elements that describe the latch and unlatch operations associated with the plurality of cam elements.

A control system, comprising:
- a motion control axis, comprising a microprocessor-based control unit coupled to a motor;
- an output device coupled to receive position feedback from the motion control access, the output device comprising a microprocessor and a memory having control logic stored therein, wherein the control logic controls an on/off state of the output device in response to the position of the motion control axis;
- and
- a programming interface usable to program at least one of:
- the state of the output device via an output cam instruction or the position of the motion control axis via an output motion control instruction, the programming interface comprising an axis motion control instruction executable to control movement of the motion control axis and an output cam instruction executable to control the on/off state of an output device responsive to a position of the motion control axis;
- wherein the programming interface provides a graphical representation of a plurality of output cam profiles as line graphs ordered by output bit and depicts latch and unlatch operations of individual cam elements as rising and falling edges of a line graph as a function of position and time;
- wherein the programming interface permits a user to redefine at least one of a plurality of cam profiles by manipulating the rising and falling edges of the corresponding at least one line graph;
- wherein the programming interface provides a tabular representation of the plurality of output cam profiles that displays a grid of data values that represent the latch and unlatch operations associated with the plurality of individual cam elements;
- and
- wherein the output cam instruction is configurable to utilize at least one of control logic stored in a controller module or control logic stored in an output cam module.

A system for programming a control system, comprising:
- a processor;
- an axis motion control instruction executed by the processor that controls movement of a motion control axis;
- an output cam instruction executed by the processor that controls a state of an output device, wherein the state of the output device is either an on state or an off state, wherein the output cam instruction controls the on state of the output device by latching a cam element that controls the output device in response to the position of the motion control axis and controls the off state of the output device by unlatching the cam element that controls the output device in response to the position of the motion control axis;
- and
- a programming interface depicting a graphical view of a plurality of output cam profiles as line graphs ordered by output bit that represent the latching and unlatching operations as rising and falling edges, and depicting a tabular representation of the plurality of output cam profiles that includes data values describing the latching and unlatching operations.
