Hi, I have been using Stratix 8000 switches and also do not like the long boot time. Don’t believe 3 minutes it more like 5+. I discussed this my IT guy he was so what’s the big deal? We use HP switches/routers and that’s normal. If you don’t like the long boot then I’ll get you a UPS he says. So I now have my 8000s fed from two sources so they stay up when the panel power is killed. And then a UPS on the dedicated power circuit feed. Now I know it sounds like I am complaining well, cause I am. But, I do like the switches and they have performed well. We have set up 4 ports on our Plant machinery VLAN and the other are on the machine subnet. As I am the ultimate end user a few bucks up front isn’t as big a deal so I use all pre-made Panduit Cat 6E shielded cables and run all communications in conduit. When in the panels I keep the Enet separated as best as possible and use the metal dividers that Panduit supplies to keep separation. Never had any problems or lost comms has been very robust. As for 755s I have use 3 of them to control some servo motors on a piece of OEM equipment took a bit of time to get all the set up but they work fine. They are only running rolls in a stack so no motion instructions just typical rotary stuff. Being able to keep the servos was a big, big plus. To get the equivalent AC motors would have required much larger physical size and changing gearboxes. So for me they worked well. Also have about 12 753s and those have performed well. Have mainly chose to got the 750series for the Safe off capabilities. Hope this helps?

I cannot see where there are any references to move to the next routine "JSR". Unless i am missing something it seems as if only the "main" routine in each task will execute?

Here is what I finally came up with. My Local vendor PAC specialist headed me in the right direction (thanks Shawn). sum 4 loadcells , divide each loadcell input / sum to calculate % variation, limit test % variation to determine good or bad. I will tweak a bit to convert to full % values and make a bit easier to use in my View project. Rich. Hopper LoadCells_6.pdf Load_Cell_Emu_6.ACD

You are correct I could have done a better job on descriptions and logical arrangement. I have attached V3 but still struggling how to get tolerance working as i see it in my mind. One of my problems is I’m unable to verbalize it to myself so if I can't explain to myself what i want then how can I get what I want??? Load_Cell_Emu_3.ACD

Load_Cell_Emu_2.ACD here is where i am at thus far. still struggling with the tolerance aspect. hope i attached file correctly??? Thoughts Anyone? Hopper LoadCells.pdf

I am having difficulty reasoning through a project so hoping for suggestions. Platform is Control-Logix I have 4 load-cells that are weighing a large vessel. 1) To calibrate? Empty vessel =0 -- add 400 pounds to vessel and lets assuming load-cells are reading equally distributed weight. Should calibrated weight be 100# per cell then a simple sum or, 400# per cell / 4? 2) Now I want to compare each load cell to see if they are all within tolerance of each other so how to best compare 1-2-3 to 4, 2-3-4 to 1, 3-4-1 to 2, 1-2-4 to 3? I am not looking for anyone to write my code just some ideas. Seem to be hitting a wall here.

I had do the same recently to prepare a training manual. I ran the project on my laptop from View Studio. I then captured screen-shots from my laptop. I use a shareware screen capture program Print Key Pro. It allows you to capture only the specific area of your screen where the PV image is running. I save as JPEG files works great.

If you are using the Rockwell USB Dongle then i think all you need to do is copy the activation files from your laptop to your other PC. The activation files are located in document-all users-rockwell automation - activations. Or something close to that. I have Win 7 so the structure is a bit different on win 7 the activations are users-public-public document-rockwell automation-activations. These are the files that tie your dongle to the activation. This is one of the main advantages of the dongle it allows you to have the activations on many computers. The dongle is as i understand it simply a mac address that the activations need to see to run the programs. Hope this helps

Any Ideas
