RSlogix500 B3 file bit number

[unsaint33]

In RSLogix500, is there a way to make B3:1/1 to show as B3:0/16? In the below drawing with keyboard letters, --II-- is a rung with a normally open contact.

From this

B3:1
--II--
1



to this

B3
--II--
16

Sure, change the binary bit display mode to /bit instead of word/bit.

Right click in the ladder, properties, and go to the address display tab.

You will not see B3:0/16 but you can see (using Dravik's configuration) B3/16 (word 0 only has 16 bits 0-15 B3:0/16 is not a valid address)
which is the same a B3:1/0

B3:1/1 is B3/17

 

[drbitboy]

I am pretty sure that B3:1/1 is actually B3:0/17, and it will display as B3/17, but assuming that [B3:0/16] is a typo on the OP's part, Dravik's answer still stands:

Got it. Thank you.

Is there a way to do the same for timers?

Is there a way to do the same for timers?

Not that I'm aware of.

Timer data structure is actually three words.
One for the .EN (enabled bit) .TT (timing bit) .DN ( done bit)
T4:0.EN T4:0.TT T4:0.DN

One for the Preset .PRE
T4:0.PRE

One for the Accumulated Value .ACC
T4:0.ACC
