  1. Micrologix 1000 Invalid STI Interupt Setpoint Fault

    Thanks for you reply. There is no value for the setpoint, it is 0. The STI looks exactly like your picture. I will try to post the program.
  2. Hello A-B Guru's, I have a small station with a Micrologix 1000 controller in it. Keep getting a "Major Halt Error S:1/13, Invalid STI interrupt set point. Refer to S:30." It is a very simple program, not using the STI instruction. Have a filter on the processor power. Nothing crazy going on, on the station, no big coils, etc. What can I do to prevent this fault from occurring? Can I add a line of code to always unlatch S:30? What should I do? Please help.
