Hello,

I'm a bit of a beginner to this so please bear with ... I have a Fanuc 30i and I'm trying to understand how to implement sub51 to read parameters to an R address which I then want to access in ladder. My issue is I don't understand how to reference each parameter using the window function. Basically I would like to know if anything on the first page of the parameter screen has changed from 0. Would anybody be able to give me an example of a window function setup in R addresses starting at R2600 for instance, for the bits highlighted with red squares in the attached image please.

TIA !!!!!
