Abstract
To provide a controller capable of facilitating changing of the order of robot cells, a control system, and a ladder program. A master PLC includes a master input unit that receives a first input signal indicating the order of operation of robot cells, and a second input signal indicating work completion in the robot cells from each of the plurality of robot cells; a master output unit that outputs an output signal for instruction of operation to the robot cell specified on the basis of combination of the first input signals, and the second input signal according to the ladder program; and a storage unit that stores a plurality of the ladder programs corresponding to a plurality of patterns of the order of operation comprising at least some of the plurality of robot cells.
Claims5
A controller that sequentially operates a plurality of robot cells by a ladder program, the controller comprising:
- an input unit that receives a first input signal indicating the order of operation of the robot cells, and a second input signal indicating work completion in the robot cells from each of the plurality of robot cells;
- an output unit that outputs an output signal for instruction of operation to the robot cell specified on the basis of combination of the first input signals, and the second input signal according to the ladder program;
- and
- a storage unit that stores a plurality of the ladder programs corresponding to a plurality of patterns of the order of operation comprising at least some of the plurality of robot cells.
A control system comprising cell controllers that control each of a plurality of robot cells, and a master controller connected to the plurality of cell controllers, wherein
- each of the cell controllers comprises:
- a first cell output unit that outputs a first cell signal indicating the order of operation of the robot cell that the cell controller controls among the orders of operation of the plurality of robot cells;
- and
- a second cell output unit that outputs a second cell signal indicating work completion in the robot cell that the cell controller controls, and
- the master controller comprises:
- a master input unit that receives a first input signal corresponding to the first cell signal, and a second input signal corresponding to the second cell signal from each of the plurality of robot cells;
- a master output unit, that outputs an output signal for instruction of operation to the robot cell specified on the basis of combination of the first input signals, and the second input signal according to a ladder program;
- and
- a storage unit that stores a plurality of the ladder programs corresponding to a plurality of patterns of the order of operation comprising at least some of the plurality of robot cells.
A non-transitory computer readable medium in which a ladder program is recorded, the ladder program for causing a controller that sequentially operates a plurality of robot cells
- to output an output signal for instruction of operation to the robot cell specified on the basis of combination of first-input signals, and a second input signal
- in response to receiving of the first input signal indicating the order of operation of the robot cells, and the second input signal indicating work completion in the robot cells from each of the plurality of robot cells.
