Actually I see that I forgot to add in the math for creating V2000 as the combined hour/minute information. But just grab it from earlier in the thread.

Nice job Bernie!!! And thank you for the note...I am heading up to a Digester conference in NY later this month, still fighting with the USDA over $$$$$...

:site:

I just read Bernie's last couple replies and I am totally amazed, I dont even know what to say right now. I am going to load his brilliant work into my DL04 440cpu and study this masterpiece!!!!!!!!!! got to do a couple backflips first! wow!

gr8benwa · Mar 10, 2012

Well its been a few days and I have been trying to figure out this program Bernie wrote. I also created a very simple program for my personal HMI to try and link it up with bernie's magic.

I'm learning a lil more everyday but still not enough to understand why v2000 only reads 0 and why _sp0 stays false while _sp1 stays true. I haven't got C0 to ever go true either. I tried making a few tweaks to see what would happen but I loaded bernies original monic back in since my tweaks were just an experiment. im going to load a vid to youtube and link it here showing the ladder and hmi in run.

ok here is a vid showing my ladder and hmi running.

hope I'm just missing something simple , but yeah I'm confused.

thanks!!!!!!!!!!!!!!!!!!!!!!

I am concerned that V2000 remains zero. Check your real time clock registers (V7766 through V7771) for correct values. If not try using the Directsoft command to set the date/time.

The cycling of V2020 is correct. It is rapidly cycling through the 40 rooms, checking their entered On and Off times against the current time (which should have been in V2000).

If you have not set up the memory locations for the on and off times for each room for each day of the week (an admittedly long process) you will probably not see C0 turn on.

SP0 and SP1 are behaving exactly correctly. You won't see SP0 as ON since it is ON only for the very first scan. SP1 - note the name 'ON' - is ON.

Otherwise there is a lot of understanding of the memory layout (included as attachment) that I proposed in my posts and the nature of pointers. Just follow the first of my 3 posts. Don't worry about the total program I posted until the very end.

I am concerned that V2000 remains zero.

At the bottom of Rung 3, it seems like if the clock register V7770 is not set properly, then V2000 will always be zero:

LD V7770
MUL K100
ADD V7767
OUT V2000

I might be wrong, but, looking at the video, it looks like you may be trying to use the original file in post #15, not the updated file in post #17.

bernie_carlton · Mar 10, 2012

I think you may be right about the version of the program.

But I had hoped he, or anyone for that matter, would start with the first post (with the added hour/minute logic for V2000) and understand it first before progressing.

gr8benwa · Mar 10, 2012

oh my! faceslap!!! yep... sorry it was 4 in the morning and I loaded up the monic from post 15!

gr8benwa · Mar 10, 2012

OK, v2000 does work correctly . wow staring at a computer screen for hours can make ya batty! lol. Now I have discovered that my c-more HMI and 440 PLC are not communicating with each other. I am not sure what I did. I will make another vid and see who spots my goof this time! lol. I sure have better luck with Allen Bradley.

jrwb4gbm · Mar 10, 2012

I'm glad you got the V2000 working, things go bump in the night sometimes. Take a quick look at this thread.

It is for EZ to AB but maybe it will help. Check all the comms settings and cable connections. Make a simple EZ tag and a test rung in the PLC. You can use an ON-OFF button to watch to see if the bit is going into the PLC

gr8benwa · Mar 11, 2012

since i didnt want to get off topic i started a thread about my hmi/plc comm problem.

put a vid there to see who can spot waldo, i mean my error! lol.
