My first program in the real world has reared a couple of issues. I spent all day trying to figure out what I have wrong. Both sets of Pumps (DA & HW) are suppose to rotate every seven days. This is not happening. My hours are displaying on the Cmore correctly. One issue thats making things difficult is on the DL06 I have to unplug the Cmore to plug in the laptop, this obviously kills my ability to make changes thru the Cmore while monitoring the program. One other problem since I started the pumps. We have had several power outages (storms). After the emergency generators come online the pumps have to be started back up. It would be nice for them to go back to pre power outage position. I have no idea how to accomplish this. Thanks to all David

The 06 has a built in clock, with Day of Week in V7771, you should just cycle your pumps every time it rolls over to 0. That will eliminate your entire week timer logic. You should keep track of your selected pump in a V Memory location that is set to retentive, or even better in NV memory. As for your Programming and HMI at the same time issue, you should invest in a D0-DCM card, which will give you a second RJ12 port. Also, I suggest getting into the practice of documenting your program thoroughly, meaning every element you use. You may understand it all perfectly right now, but in six months when you go to troubleshoot you may not.

I agree with JoeW. Documenting the project is key for any project and good for repeat business. Look at the attachment for a program I wrote to control 6 2,000 Ton Hydraulic Presses. Each of the 6 presses has a C-More operator interface. I connected two HMI's to a hub, then to a ECOM card. But, I'm sure anyone can open my logic and understand the flow and see what I was thinking by the doc's.

I have a mistake in my pump rotation and I am unable to find what is wrong. The Pumps rotate from #1 to #2 on the seven day count but do not rotate back. I would appreciate it if some one could point out my mistake that i cannot find.

David,
I could not download the PDF. I'm presuming the attachments problem still exists (see the sticky post at the top of this sub forum). Perhaps you can export the program as a txt. file and paste it to your next post.

David and other forum members,
I was able to download the PDF. Sadly I will not be able to reply with diagnostic information before Saturday. Anyone else care to help him out in the mean time?

Without the actual program to look at, what I see is that Week FF DA is used in rung #1 and rung #8 as an output. Output coils can only be used once in a program in order to work correctly.

Email it to me at billf@clarkpulley.com . Please zip all the files together. I'll look at it and see what I can do. I have a simulator here on my desk.

Also CC a copy of it to billfloyd806@yahoo.com in the event the IT department (Our Stereo Techs) block it.

The easy way is to go into Directsoft with your project open, select File -> Export -> Program. Then take the text file that it creates and post it here.
