Top of master/main job start?

    Hi again all,

    Does fanuc have a signal to let me know I'm at the top of the main/master job? Or similiar.
    R30iB controller.
    This signal is very helpful with motoman, in the plc I can inhibit starting unless the highlight line is at the very top.
    I know I can reset and abort but this doesn't check that the operator didn't touch the teach pendant.

    You can create this operation in your program without BGLogic. Simply set a bit at the end of your program on. Then turn it off on the first line of your main program. Only of the program made it through to the last line would the bit be on when the PLC goes to start it.

    We always set CIStop to abort and all starts will start at the first line. This will require some checks or special moves to make sure the robot can move to the first position freely. We just create a complex homing routine that does nothing if the robot is in the position that it is expected to be in if the program finished correctly.

    Yes, I may use the option to monitor the teach pendant switch.
    I3ooI3oo,
    This is my main concern is that I have interlocks and registers I'm using within all the subprograms. (Since this is a very compact area, and many DCS zones are not within the time or budget unfortunatly for interlocking. )And at the very beginning they all get reset. So if the operator starts from beginning everything is ok. No matter if they go through and FWD or toggle some IO or registers during manual. I don't care as long as it always starts from the top of master program.. (in the case of setting a bit at the end of the program as mentioned, I worry about someone getting smart and FWD through that line, turning the bit on, then re-starting from some other spot in the program.

    Sorry I don't mean to argue your comment, I appreciate them all! I just want to understand if I am missing something, since I don't work with them all the time.

    Thank you
