inv002_refresh scanlist

[Bobodopalus 2]

Hi all

Can someone please clear the scanlist value up for me which is part of the INV002 function block

the documentation says that whatever nodes you have assigned are what bits you need enabled in the scan list

they give the example of node 1 and node 14 being used from this they get a scan list of #4002, where does this number come from?

for my next job i will be using 3 inverters and am not sure what my scanlist should be

Hex #4002 - each digit is 4 bits.  So, Hex 4002 means 0100 0000 0000 0010 (which would be bit 2 and 14 on).

i think i get it now that is actually bit 2 and 15 right? so do they ignore the first bit for the node value?

so if i want node 1,2 and 3 active i would need 1110 which would be #E right?

The bit numbers start with 0 (bit 0 is far right, least significant).  It is bit 1 and 14 that are on.
