How to create specific text on Logo display

Hello, I am looking for an idea on how to program something.

I have the following table:

Step   Q1   Q2   Q3   Power

0         0     0     0       0%
1         0     0     1     30%
2         0     1     0     42%
3         0     1     1     53%
4         1     0     0     65%
5         1     0     1     77%
6         1     1     0     88%
7         1     1     1   100%

So, there are 3 outputs and with those I switch power on 7 stages to some device .

I would like to show status of power on Logo display (like Power=30% etc.).

Any idea how to accomplish that?

Hello Frayer

In the attachment a possible solution.

This is extracted from an old program of mine. I currently don't have the time to test it because I am on the road for work. 

If it is not what you need or it doesn't work, please delete it

Maybe Frayer is only asking for a power status display and the program to control Q1, Q2 and Q3 is ready. Then it is an easy way to create power display with two multiplexers and arithmetic block, see file in attachment.

Yes, Scorp, you are right: I already have a working program (but I will check those solutions too…) and I was just asking for a way to display it; sorry if I wasn’t specific enough.

Scorp, your solution is perfect, thank you very much! 

P.S. Step-up and step-down program by others Will also be useful for manual setting of power, which I dont have at the moment. Thanks for that too.

Excuse me: what is this "VM mapping"? I never used Network inputs, can you explain purpose and use?

I tried your program, but lower part for Power% doesn't work for me, did I enter something wrong?

Since I don't know how to use Network inputs, I tried with normal inputs, but simulator gives me wrong number in %.

Can you check program, did I do something wrong?

Thanks, I think I got it now.

BTW, there is one thing which bother me a lot on programming with Logo, compared with other PLCs:

You can use a particular bit/input/output etc. only once in a program.

On other PLCs (by Siemens and others) you can set/reset/enable bit once (or more times) in program and check it several times in your program, the same bit.

For instance, bit "Automatic mode" I normally check several times in different part of program. But in Logo I can use it only once and if I want to check it several times, I have to make a lot of long wires, which is unpractical and not transparent to see a program flow.

Is there a way to bypass this limitation or make program different, more readable?
