Allen Bradley PLC Sequence Programming Tutorial. MOV Decimal Part 1
HTML-код
- Опубликовано: 20 июл 2021
- In this lesson we are going to show how to program Allen Bradley PLCs to use the EQU Equals instruction and MOV Move instruction to track machine sequence steps. One key advantage to the PLC programming methods in this series is they work with all Allen Bradley PLCs including the Controllogix and Compactlogix with Studio 5000, formerly RsLogix 5000, RsLogix 500 for the SLC 500 and Micrologix PLC, and Connected Components Workbench for the Micro800 PLC. In fact these methods work with most all major PLC manufacturers.

So glad I came across this video. I was taught this by someone who retired and somewhat understood it but the way you teach it makes it more simple for us noobs to understand. I Like how well this method works when a machine issue issue occurs. Makes troubleshooting a bit easier.
Glad to hear it!
Thanks for this. This is the way I do it, but that is just because I learned from hacking on another guy's PLC to make changes/fixes and that is how he did it.
Keep up the good work.
You are welcome!
THIS IS WHAT I'VE BEEN WAITING FOR ! and now that it is right in front of me I feel stupid, I've done way more complicated stuff than this.
Glad it was helpful John!
Many thanks Tim. This helped me a lot.
Great to hear!
This method works great with non-linear sequences
Hi Tim, great channel, like the way you explain the methodology of what you’re doing and why. with software it’s a team of individuals and we’re always learning so it’s great to get a different perspective for certain things.
Glad to hear it!
This is the same method I use for sequencing, including separating decisions from actions. The only difference is I use a CurrentStep and NextStep. At the start (top) of the sequencer, I move NextStep into CurrentStep. Each rung monitors CurrentStep (EQU) and when the step is satisfied, it fills the NextStep (MOV) value. The output section and anywhere else in the program that is dependent on the step also monitors CurrentStep (EQU). This way, if there is anything in the rest of the program that is dependent on a particular step having to occur but the next step is already true, it will still at least get a "OneShot".
Good morning sir
I'm watch first time your you tube channel nice sir
Thanks and welcome
Good job
Thanks
can i have a software , or can you please give a link to download that soft ware. thanks appreciated in advance..
If you are looking for free software, check out Connected Components Workbench. Here is a live stream I just did talking through downloading and getting started.

This is awesome 👍. Will you be able to make a HMI video that has a message display to let the operator know the next step or what step they are on?
That would be a nice addition. Let me put that on the list. Thanks for the suggestion!
I use this method as well, especially with motion. But, my question is, would it be better to combine the outputs program with your sequence program so that each sequence step would show its related output? If not, why? Thanks in advance!
No, it wouldn't be better to combine them. In a basic program, where only one output is on in one step it would be OK. But in most processes, one output may be on in step 1,2,4, and 6 and another may be on in 4 and 5. At that point, combining them will be be confusing.
What Lab-top would you recommend for beginners to inter act with PLC ees ?
Any basic laptop will work fine.
If you are still doing Micro 800 tutorials I would like to see a recipe program with the PLC and HMI, to the AB documentation is not that clear. Setting up the recipe, ingredients, upload/download etc. Enjoying the videos you have done... thanks,
I don't use the built in Recipes often but let me see if I can put that on the list for the next time we are working with the Panelview.
Tks
You are welcome!
Hi Tim greetings from Bolivia :D, can u help me? , I have a micro 830 and was tryng to update the firmware, but it failed, now I can't establish communication to the PLC, and the fault light is flashing
It's never good when a firmware upgrade fails but I red flashing light is a good sign. I think you'd be best to call Rockwell support on this one.
I only use rs500 I took a class on it at the local college and got good at it I come from old relay logic so it was not bad moving to SLCs and Micrologix but now with the newer stuff I feel like I don’t know anything . I don’t see why AB wouldn’t just keep RSLOGIX 500 and the processors for us older guys , I hear it is being slowing pushed out and at that point I guess I am done programming, I am not good with computers but I can program 500 super simple platform
Hi John, this live stream may help were I walk through converting a RsLogix 500 program to Connected Components Workbench. Once you get the hang of it, it is actually easier than RsLogix 500.
