Function Description

This function block writes an I/O output signal of robot controller.

Robot controller's port number corresponding to the bit number will be turned ON/OFF. For example, to turn ON the port number 20 of the robot controller, specify IoType : 1, IoBitNo : 4, and Value :TRUE.

The following tables show the correspondence between robot controller port number and bit number.

  • Hand I/O
    IoBitNo Robot controller port number Robot controller I/O name
    0 64 Hand output
    1 65 Hand output
    2 66 Hand output
    3 67 Hand output
    4 68 Hand output
    5 69 Hand output
    6 70 Hand output

    7

    		 71 Hand output
  • Mini I/O
    IoBitNo Robot controller port number Robot controller I/O name
    0 16 CPU Normal
    1 17 User output
    2 18 User output
    3 19 User output
    4 20 User output
    5 21 User output
    6 22 User output

    7

    		 23 User output
    8 24 User output
    9 25 User output
