INPUT AND OUTPUT SIGNAL PROCESSOR

PURPOSE:To eliminate the need for an interlock board by inputting data from peripheral equipment, etc., directly to a robot control board and processing the data by using mask control words stored in a RAM. CONSTITUTION:An input/output signal processor provided in the robot control board consists of a RAM 12, a ROM 13, a buffer 7, a latch circuit 14, and a chip control circuit 15 which are connected to a CPU 11. Further, the latch circuit 14 and a photocoupler 16 are connected to the buffer 7, and the peripheral equipment 1 and the relay driving circuit 24 of a robot 14 are connected to the latch circuit 14. Then, data on the operation states of the peripheral equipment 1 and robot 4 are inputted to a data input means 20 and a processing means 21 performs mask processing, bit by bit. Further, output data is computed on the basis of the data processed by an arithmetic means 22 and an output data processing means 23 performs mask processing, bit by bit, to drive a relay driving means 24.
