Hi Philip - I hope all is well. You helped me in this thread to get a PanelView 2711-T10C3 up and running in September and October. At that time, I had one unit that had stopped working and I had a refurbished unit that had been purchased recently . Hoping that it was just the screen that had failed, ...

Thanks Philip, That is a big help! As a side question, would you happen to know if this PF70 (20AD1P1C3AYNNNC0) I'm working with supports a means by which I could upload all of its parameter settings onto my PC? I figure before I make any changes, I'd like to make sure I have a full backup. Im hoping ...

Hi, I have been asked to implement what I hope might be a fairly simple change to the way two PowerFlex 70 drives are controlled. The exactly model I would be working with is 20AD1P1C3AYNNNC0. These PF70 drives are used in a roll-to-roll web handling application for web tension control. The ...

I agree with the advantages of migration. This is similar to something I have run into many times. This is an old PanelView communicating with 10 old MicroLogix 1000 controllers that control an old 10 station UV curing system (no longer supported by the manufacturer) on an old printing press (also no ...

Thanks Fuzzy, I had someone touch and release every touch cell and then restart. We were lucky and at least for now, the issue went away! I recommended that if this is an important machine, they should probably get another refurbished one of these PanelView's on hand. I imagine there is no ...

Thanks Fuzzy, The picture below shows a picture I took 3-4 weeks ago of the failed unit, before we replaced it with a refurbished unit. On this failed unit, the Fault Light was blinking Red and it behaved as though no valid application was present. Regardless, I was still able to upload the original ...

Hi, About 3 or 4 weeks ago, I was trying to help restore an application from a PanelView 2711-T10C3 that had stopped working. I was able to use the WinPFT File Transfer Utility to upload the .PVA file from the failed PanelView and then download the .PVA file to a refurbished PanelView. I was working ...

Hi Philip, I am happy to report that after using the WinPFT File Transfer Utility (using a 3rd party 1747-UIC) to upload the .PVA file (10LAMP.PVA) from the "failed" PanelView (which was showing Error 1110 - No Valid Application), I was able to download this .PVA file to the refurbished PanelView ...

Hi Philip, Please ignore my previous question. I was able to establish communication over DH485 with the PanelView and with all of the MicroLogix controllers on both machines (one on which the PV is working and one on which it isn't). I uploaded from the working PV first, and chose to use the original ...

Thank you Philip, I arrived on site this morning, hoping to try the 1747-UIC with a new 1747-C13 cable I made myself. It turns out that the 1747-UIC that was purchased by my customer is not an authentic AB part. It is a third party "reproduction" from a company called plccable.com. This rather than ...

Thanks Philip, That is a very big help. QA58061 mentions that "PanelView Standard terminals contain a real time clock module. That module contains a battery in a socket for the real time clock and static ram for parameters and configuration information." This makes me think that if the battery did ...

Thank you Philip, I had a chance to visit the site where this PanelView is located. I learned that after their old unit had failed and they had purchased a refurbished unit, the first step they took was moving the control board from the failed unit to the refurbished unit, hoping that if it was ...

Thanks Philip, If I were to buy a 3rd party PCMCIA card, should I be concerned about an upper limit to the storage capacity? Doing an online search makes me think that ones with higher capacity are now more prevalent than those with lower capacity. For example, I found this one that is described ...

Thanks Philip, That sounds promising. I will ask someone on site to look and see if either the working or the the failed unit have a PCMCIA card installed. If they do not and I want to get one, is there anything "Rockwell / Allen-Bradley" specific about the cards that work with these PanelViews? ...

Hi, A company that I am affiliated with has a machine with a PanelView 2711-T10C3. It failed and they purchased a refurbished unit. Obviously, the refurbished unit does not have the application on it that serves as the interface to the machine. They have a more or less identical machine on ...

Thanks Bob, Your point is well-taken. Given my known cyclic (once per revolution) variation of my PV even with a fixed CV, I just can't think of an advantage of having my PIDE chase this variation. I'd be afraid that as soon as my PV indicated an increase in tension, the PV would naturally be on the ...

Thanks Philip, That helps a lot. Let's say data from my customer indicates that CV = 10% results in their desired tension at max diameter and that CV = 5% results in their desired tension at minimum diameter. I would then come up with a formula to control the value of a tag named CV_FF such that CV_FF ...

Thank you Phillip and Keith for your replies, and I apologize for my delay in following-up. As Keith suggested, I think executing my PIDE more slowly and filtering (or averaging) the tension signal to prevent the PIDE from trying to control my once per revolution anomaly will help my cause. ...

Hi Phillip, Will, Pradeep, Chip, and Bob, Thank you all for your helpful replies. I agree with Bob and Phillip that the process as I have described it may not warrant closed loop PID control, and the periodic (once per revolution) variation in my PV even with a fixed CV will likely make tuning a PID ...

Hi, I am trying to use PIDE loops (in a ControlLogix PLC) for tension control on a roll-to-roll web handling machine. This machine has a two unwinds and two rewinds that are used and controlled in different ways, but I will try to simplify my question by limiting it to one particular unwind. ...
