Abstract: A programmable controller 1, capable of programming the whole operations of the factory cell 3 including a robot, is provided with a program input device 11 and comprises: a memory for storing the program, a discrimination means 13 for discriminating the blocks within the program which define the movements of the robot; an information generation circuit 14 for generating information relative to the movement of the robot, which is transmitted to the robot controller 2 via a communication means 16a; and an instruction processing circuit 15 which executes via the contact input and output circuits 17 and 18 the instructions other than those of the robot defining blocks, relative to the states of contacts and relays of the factory cell 3, in parallel with the movements of the robot controlled by the robot controller 2.
