Ok, any of you guys who are pros at RSLogix 500, I need some advice.  I
am programming a SLC 5/03.  I have about 60 devicenet valve actuators
that I need to program.  Instead of copying all the rungs over and
over, and then if something changes, I have to redo all of them.  I'd
like to be able to setup one program and pass the addresses of the
valve acutator's inputs/outputs.  I guess what you might call indirect
addressing.  I need some direction on how to approach this programming
method.  Thanks.

proclaimed to the world:


You can have all the rungs set up to control the actuators, look at a
"master" output's state in a rung set up just for this. The logic can
the be changed in just the master rung.

Be well,

indexed offset addressing

create table, send table to valve using a MOV block type command - index
start address - MOV - index etc

Thanks guys, got it working on 12 rungs instead of 200.  I used indexed
addressing, but got to play with the indirect method too.  Both ways
are very efficient.

For a RSLogix ladder logic example of Indirect Addressing and more ...

If your 5/03 is not wired to any real world outputs, or you have an
extra in the shop, you can load this working program in SLC 500 and
study how it works. It is fully discriptored and comes with a printable
PDF copy. It might help you out.
