How to take input and convert to integer?
I am working the Productivity PLC programming software for the first time, learning basic programming. I am trying to recreate a program that use a MOV command (SLC 500) to place a value in a stored integer (0=OFF,1 = ON ,2 =AUTO) for status. This status is then used to set RUN,OFF,AUTO based on what the value is using a compare function. I do not see a command equivalent to the move command in the Productivity suite. I could use the MATH function and just output a constant, but that there may be an easier way. What would be the way to do this?
You're probably looking for the CPD (copy) command. Like MOV but allows up to (50, I think) items to be copied at once.

Another method would be just to set the bit in the output register that you want based on the condition.
Example:
Tag OnOFFAuto = 16 bit unsigned.
You are basically setting the first two bits of the 16 bit word.
OnOFFAuto:1 is the bit of the register tag.
OnOFFAuto:2 is the second bit of the register tag.
When you look at the tag as a whole, you will have a 0, 1 or 2.
I hope this makes sense to you.

As mentioned above several ways to do this. Three options below. The logic below is assuming input 1 & 2 cannot be on at the same time.
Thank you all, I was able to get this to work.
