i have an auxiliary encoder for my x and y axis ,i need to write a macro to divide the count by 0.25 to get my correct ratio to display my position where and how do i do this

I've never used encoder counts for anything, but I would try putting the information in the PLC Script.  EncoderCounts / .25
Not sure if this will work, but I've got stuff running in the PLC script and it updates VERY quickly.
