Hi Shane. In the MAPC.instruction. What's about the inertia of slave axis? I am modifying an application and I can't get the slave to do what the master does. In physical positions. Gracias.

[@ShaneWelcher]

Then you should verify the inertia from the motor name plate. Also, the physical setup. There are a lot of variables when it comes to the use of an MAPC. Like the servo attribute setup by the programmer along with timing of the system just to name a few

What about a physical input where an operator will be pressing a button? If a 0 is written to that input out of the if statement the physical input will overwrite back to a 1 for the next scan right?

[@ShaneWelcher]

It is based on the bit used in the statement of the example I gave in the video. Meaning, if the bit is active then the function will happen then write the active bit back to 0 however, if held then it will one shot again based on scan. Hence being a one shot statement. I hope that answers your question

@@ShaneWelcher I think what he is asking is the physical input will set the bit to a 1 when held. Much like the instruction will set it to a zero... so which one has the priority. Then again Logan, usually you wouldn't use the physical input address directly, you would reference a bit much like Shane has reference it to the IncrementUp bit

@@darthenx2585 I agree, in general use you would use a bit although I have another video in my structured text playlist showing the same example using a real world input.

@@ShaneWelcher Ah I just watched that. Good video. Think I understand what you are after now with all these. Thanks man! Appreciate the videos also, btw.
