Find set bits and there location in a 16 bit word

[echomayor 0]

I need to search B3:0 and find which bits are set and there location in RSLogix 500 using Micrologix1400.  Using it for part tracking

Thanks for any suggestions.

Scroll down the left side to fing B3 file and double-click it.  Then click usage.

For references to individual bit, then the bit and right click and select Find.

you can test individual bits using XIC and bit address, such as B3:0/3

if word contains several bits that can be set and you need to identify ONE bit that is set, just calculate

A AND (-A)

where "A" is an integer memory location such as N7:0 or B3:0

this is much faster than iterating through all bit positions one by one.

also this is much simpler to program - only two fundamental instructions that are available on any type of controller.
