An equipment unit state controlling method and device, and an equipment unit. After receiving control data transmitted from a state controller, a unit controller detects whether the unit controller communicates with a display panel controller, in which the state controller transmits the control data to the unit controller and the display panel controller simultaneously. If the unit controller communicates with the display panel controller, the unit controller performs an operation on the equipment unit corresponding to instruction information transmitted from the display panel controller, and if the unit controller does not communicate with the display panel controller, the unit controller parses the control data by itself to obtain the parsing result and performs the operation on the equipment unit corresponding to the parsing result.

An apparatus and method for establishing triggers for the opening of one or multiple gates to a mold cavity of an injection molding system, followed by a sequence of predetermined valve pin movements over the course on an injection cycle. In one embodiment, the invention provides a graphical user interface and control system enabling a user to select from and arrange a plurality of virtual icons into a user-defined virtual sequence that define associated triggering events and actuator controlled pin movements over the course of an injection cycle. In various embodiments, the apparatus and method allows the system operator to view a simulated profile of such triggers and movements and to compare the simulated profile to an actual profile to access differences and make adjustments to the triggers and sequencing more quickly and efficiently. This is particularly useful in sequential molding systems where multiple gates need to be programmed and adjusted to compensate for variations from a predetermined sequence.
