Allen Bradley PLC Sequence Programming Tutorial. MOV Decimal Part 1

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.

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.

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.

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.

Good morning sir
I'm watch first time your you tube channel nice sir

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".

This method works great with non-linear sequences

Many thanks Tim. This helped me a lot.

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,

[spudmonken]

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!

[gilbert-plclearningchannel]

can i have a software, or can you please give a link to download that soft ware. thanks appreciated in advance..

[chriswipatothai]

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?

What Lab-top would you recommend for beginners to inter act with PLC ees ?

[danieltf]

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

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
