If you just need a 2 hour batch counter, did you look at the other timer types available?

If you choose a "TMRA " accumulating timer, reserve 2 consecutive words for the 8 digit preset and counting areas, you can count for 2,777 hours if needed.

Much less confusing. Will that work for you?

Ok Bob,that will work for me.What will now be an easy way to display on a HMI ____ hours Remaining(V4000) ____ Minutes remaining(V4002)?My code below is not working for me !

Kevin, I didn't import this to try, but these changes might help. Perhaps C0 wasn't on when you wanted to see values. Also, once seconds are converted to minute, you only need to divide by 60 to get hours.

// Rung 9

// Address 43

STR C0 change C0 to sp1, always on

LD V4004

SUB TA2

DIV K600

OUT V4000

// Rung 10

// Address 48

STR C0

LD V4000

DIV K600 change k600 to k60

OUT V4002

Good Luck, Bob

Tanno,

I can't help you because rung # 3 uses binary to real and real to binary instructions both of which are not supported by the DL05. But the good news is. If you post what you need,(are you using an eztouch?)(are you trying to make a 2 hour timer?) maybe somebody smarter than myself can help.

I need a count-down timer that works on the DL05 and the EA7-S6C C-More panel.

I 've tried and tried and tried. I'm new to PLC programming. I'm doing this one from scratch....never done that before.

I 've tried using the UDC in DirectSoft32 4.0 and no luck. It doesn't work like the manual and online instruction say.

So, I tried using a standard timer and subtracting the entered value from the timer value and I get numbers, but not accurate and they are all over the place.

I 've divided it by 10, 100, 60....nothing it getting me what I need.

I'll probably start a new thread asking for this because it doesn't have to do with the 06.

Tanno,

I have only used the EZ-touch panels (not the C-more) but something that you may need to check is the number format.

You say that you are new to PLC programming. Do you understand BCD numbers? If you display BCD numbers as if they were 'binary ' numbers, then it will seem that your subtraction is inaccurate.

The Koyo (Automation Direct) PLCs use BCD for timers, counters and native math. When you create tags for the HMI be sure that you specify that they match the format of the Vmem* that you are looking at. That should be an editable property of tag. (Also make sure that display object in the HMI uses the correct fromat.)

*Vmem is a container only. You can look at/use the value in a particular Vmem (e.g. v2000) as binary, or BCD, or bits, etc. Just make sure that you use it consistently.

Yes, that's what I 've done. I 've made sure that BCD was and is used everywhere.

Exception: Input for time is entered by typing in the number. And I'm unsure of the format that it's using.

The other thing, I finally got a countdown timer to work that's accurate. BUT, I can't seem to get the secs to roll over to mins and visa-versa. And the only way I could think of getting it working is I had to setup a "loading " sequence. This loads the UDC with the value that I want to countdown.

Is there a faster way to load this? I'm using sp5 (.01 secs) as the rate to load it.

At the moment, I only have one input for time and I'm using that for the secs. I haven't yet figured out any more of it.

FYI, I 've been at this for 12-hrs straight for the last three days.

Tanno,

I just remembered a post by Bernie Carlton. At http://forum1.automationdirect.com/board/Forum1/HTML/001746.html

The response from the original poster and others was positive about the outcome.
