Indirect Addressing in Studio 5000 to Store and Retrieve Data

Storing and retrieving numbers in arrays with indirect addressing in Studio 5000 / RsLogix 5000 is an important step in taking you from a basic bit PLC programmer to more intermediate task. We could use a FIFO to load and unload data but we can learn a lot about arrays and indirect addressing by doing this with some basic ladder logic.

This is great. I was confused at the index function but I could adapt this to logging multiple alarms being triggered which one activated first

Even though allot of this is hard for me to fully fallow it's cool to see how much of it i do understand and I'm growing to understand thanks for the videos

While OTL's and OTU's are the devil, my main feedback is using the same CTU in multiple locations. In situations where you have multiple things that can increment a counter, it is usually better (in several different resepects), to use either several booleans "or'd" leading to the counter, or (my preferred method) use ADD(1,index,index) in place of the CTU's. Then use MOV(0,index) to reset. It saves memory, scan time, and you don't need to deal with unused flags. Looking forward to future videos!

Thanks! this helped me understand a little bit more than i did before hand

Tim I love you, I applied this technique to grabbing and storing a analog value, and this helped a ton and much cleaner than the other example I found used by the SI's that built the equipment

Very nice I like how you do it on the fly and give us the chance to see how you fix these bugs as you develop code.👍👍

Hello Mr Wilborne , thank you very much for the answer to this Quiz , I have being traying to implement it on CCW Micro810 I hope I can get it right

Loved the video, very helpfulll...could you explain how to use a indirect value in compare routines? Old logix use a different way. Like N[N10_2]:[N10_4] but not sure how new logix works now.

@TimWilborne Жыл бұрын

You would replace that with a 2 dimensional array. Here is a video in that. kzfaq.info/get/bejne/iNJpobdhl5--o5c.html

How important are subroutines? I see them in my plants program. But dont understand why a program would use them.

@TimWilborne 9 ай бұрын

Great question. The main reason is for organization. Typically, all alarms will be in one routine, all outputs on another... It makes it easier to figure out where to go when you're looking for the problem.

@Jrjulio95 Жыл бұрын

Tim, is there is a way to generate a random numbers from 1-4 so we can do this problem backwards

@TimWilborne Жыл бұрын

Yes, you can make one that at least appears random enough for human eyes :)

@Jrjulio95 Жыл бұрын

@@TimWilborne how would you do this? I tried to do this with a timer but didn't got a random, after a couple seconds i start getting a pattern instead of random numbers
