Afi

Hi Guys,

New to PLC's. RSLogix 5 has a instruction AFI that disables the rung.

Is there one for RSLogix 500 ???

Thanks

NOPE, just make your own. Use a bit from a word in your "B" file. Myself, I use B3:3/3, it's just easy for me to remember.

Yo, Les L,

You might want to take a look at this link from an earlier thread:

more than you ever wanted to know about AFI

The stuff about the AFI starts about post #23 - but the whole thread is pretty good info.

Preview: It turns out that the AFI doesn't really "disable" the rung like the book says - the AFI simply executes like any other false condition.

Did the same thing, as using a bit address, with the symbol name of "AFI". To add it to a rung, just add a XIC contact and type in "AFI", for the address. It automaticly uses the same bit address.
