Background logic - UO[6]

    Hello,


    I am using background program to turn all outputs off when an error occurs:


    Code:


    LBL[1]

    IF UO[6: FAULT] = ON JUMP LBL[2]

    JMP LBL[1]


    LBL[2]

    DO[101] = OFF

    DO[102] = OFF


    However, I get the error: INTP-202.

    How can I fix this simple problem?

    You cannot jump back in BG logic, only forward. Jump labels aren't necessary anyways. Also, use the If statement with parenthesis. BGlogic automatically loops.


    Just use this:


    If (UO[6]) Then

    DO[101] = OFF

    DO[102] = OFF

    End If

    Thank you HawkME .


    When I go to Background Logic: MENU > SETUP > BG Logic, my Program: DEMO_BG got STATUS; Stop. I feel ike it never runs.


    Can you explain why?

    When I manually set RUN.

    The following error occurs: Invalid Item for Mixed Logic..


    I am on a fanuc robot LR 200iC/5L, software version 7.50

    So I can use IF statement, but not IF THEN


    Code:

    --------------------------------------------------------

    Program name: DEMO_BG:


    IF (UO[6: Fault]), CALL DEMO_IO_OFF


    --------------------------------------------------------

    Program name: DEMO_IO_OFF:


    DO[101] = OFF

    DO[102] = OFF
