  • Patent number: 10363645
    Abstract: A workpiece simulation part estimates the amount of movement of the workpiece from drive information and estimates the current position of the workpiece by adding the amount of movement to the previous position of the workpiece, the drive information being generated for, among at least one actuator, an actuator that is assumed to constrain the workpiece under the constraint conditions. A sensor simulation part uses the current position of the workpiece to generate sensor simulation information. An input/output switching part transmits the drive information to the workpiece simulation part and transmits the sensor simulation information as alternate information of the sensor information to the control-program execution part.

  • Patent number: 10126726
    Abstract: A technique for enabling reduction in user operations. A program generating apparatus includes a control distribution unit and a communication function adding unit. The control distribution unit allocates respective control blocks of a control model to controllers, based on the control model received by a control model input unit, and setting information and connection information received by a setting information input unit. The communication function adding unit adds, when first and second ones of the control blocks are connected to each other, a communication control block to a connected part between the first and second control blocks, the first and second control blocks being allocated to different ones of the controllers in the allocated control model.

  • Patent number: 9720400
    Abstract: When change amount information calculated by a change amount information calculating unit satisfies a start condition and a signal condition is true for an operation instruction the start condition and the signal condition of which are defined, an operation instruction execution control unit determines a start of the corresponding operation instruction and determines operation completion based on a completion condition determined in advance of the operation instruction. An operation instruction executing unit executes the operation instruction the start of which is determined by the operation instruction execution control unit and stops the operation instruction when the operation completion is determined by the operation instruction execution control unit.

  • Publication number: 20160231733
    Abstract: A program creation device includes a processing unit that displays, on a display device, an edit screen on which respective timing charts of controlled units are arrayed in the vertical direction. Upon reception of a first input for designating an arrangement position of a display object on the timing charts to arrange the display object at the arrangement position, the processing unit displays the display object at the arrangement position designated by the first input on the timing charts. After displaying the display object, the processing unit receives a second input including a designation of a type and an input of a parameter. The processing unit then generates an operation program for executing an operation command of the type designated by the second input, to which the parameter input by the second input is applied, at an execution timing according to the arrangement position designated by the first input.

  • Patent number: 8415610
    Abstract: Present invention provides an optical encoder capable of improving the precision of an interpolation angle in a single signal track, in an encoder of sine-wave angle interpolation type. The optical encoder includes a waveform, in which a phase-modulated wave is superimposed in a predetermined period over a sine-wave of a fundamental period, as a signal track (103), and an optical detector (104) for extracting the sine signal and the cosine signal of the phase-modulated wave. An operation unit (106) operates electric angles individually from the output signals of a first optical detector pair and a second optical detector pair belonging to the optical detector, and determines the sum and difference of the electric angles, thereby acquiring the electric angle and the phase-modulated wave of the fundamental period.
