Hello, I have an issue and I cannot figure it out. The program I created has a memory bit %Mx that stores the state of the Automatic mode of the program: when 0, it is off; when 1, it is in automatic mode. I hooked up a Safety Stop to input %IO23 and set it up as RUN/STOP logic.
Now the question: How can I change %Mx to 0 every time the program changes state from STOP to RUN( basacly wen emergency stop is lifted)? I do not want the machine to start on its own when coming back from an emergency stop.

I figured out how to do it i use the RESETE COIL function wen %IO23 is activated and it resets the Memmory bits to 0 and all functions are off.

I really wish that Machine Expert Basic supported arrays better. Then you could just iterate through all the %M bits on startup and reset them.
That's what I would try however, see if you can get an array to work in a for loop.
