Hi,

In a grinding machine I notice the axis will move of a quantity if I push E46.4 button.

I'd like to change that behavior, so I went on PLC (Simatic Manager V5.5) and looked for that input. It's linked to an aux memory (M222.0) but from that point I can't see where it's used.

I know the stroke is stored in R28. How can I understand where is has been stored?

Hello.

Do you have the possibility to share the project? 

I understand.

My best guess Is that it might be an interrupt.

And that R28 is used in the Interrupt NC program to define the distance.

So it might not be in the PLC at all.

M222.0 does not show anywhere else if you cross reference it?

I think it's an interrupt but I don't know how it's shaped. 

M222.0 goes nowhere in my understanding, it's only used as a condition for other things

N20 SETINT(5) PRIO=1 RIT_RAP

 And I think this is the part I need to modify. that "5" how is it linked to this interrupt? a PLC's DB?

I've found
