Micrologix 1000?

[kd8cfw]

I am trying to accomplish a program that counts from 1 to 10 in binary by hitting a momentary pushbutton I:0/5 without using the CTU or CTD commands.

Does anyone know how to pull this off? I thought maybe an add instruction but couldn't get that to work either.

Forgive me for asking, but is this a classroom or training exercise of some sort?

What happened when you tried using the ADD instruction?

Here's a hint: Think about how you'd code that in BASIC using "If" statements. Consider what state changes are happening between your two numbers. The ladder code should be very simple from there.

You should be able to use the ADD instruction with a one-shot between the input and the add instruction.
