Thanks Alex. Regards, kvj

Hi, And so I went onsite and did verification. Does it mean that the offline project is not the same as the online one? I would appreciate for your clarification.

Hi Flex, Thanks. Yes, I did. My laptop crash and needs to restart everything, and all my infos gone and I repost my question only to realize later. There is also a suggestion called to VERIFY on the menu, from my previous post Compare project file to online program Visilogic - Vision & Samba PLC + HMI Controllers & VisiLogic Software - Unitronics Support Forum: Programmable Controllers (PLC + HMI All-in-One) Regards, kvj

Hi Denis, First off, thanks to Flex for replying the same inquiry on my other post. Brilliant idea Denis, that can be a good option. Yes, I had earlier experienced scope to download the program only to a new system, ended up modifying around 50% of the program. Appreciated much. Thanks. Regards, kvj

Hi Alex, Thanks Alex for the info. Regards, Joel

Hi, I have a situation to troubleshoot V570 because of unexpected behavior on the program. I was given a program file. How can I compare if the program file given is the same as the loaded program to the PLC-HMI ? (the program cannot be uploaded) Is there anyway to do this? Thanks. Regards, kvj

Thanks for the info. How I wish they have this comparison tool and option to download piece of item like routine, as they have a feature CANNOT UPLOAD from the unit. The system is control and I can only depend on the backup file, and they are asking for modification. Anyway to at least tell these online/offline routine are different ? Regards,

Hi, Great day! I'm basically new to Unitronics product and would like to ask something, by the way, I already had one project download and modified the program, fortunately all working fine now. I got another inquiry for modification of a V570 series. The client can hand me over the project file, but not sure if its the same with the online program. Is there anyway that a project file can be compared to an online program, assuming there's no way for me to upload the online program ? Or is there anyway that I can only download a piece of routine only, not the whole program? Apology if I went straight to this forum to ask about this. I would appreciate if you can shed me light, as my client is too urgent in this matter. Regards, kvj

Hi Joe, I thank you for sharing the info. Yes, it simply works on the manual tune. I simply cannot work with auto tune. Much appreciated. Cheers!

Any help? Basically, what I did is to get the parameters from the working auto tune unit, and encoded to the second unit for manual tuning. It works for 24 hours and for some reason client made adjustment on the mechanical side and it trips again. And my question is, is this the right way shown below for V570 forcing it manually for PID ?

Hi, Unfortunately the issue is still there. 1. Adjusted all the ranges. 2. Tried Stage 2 3. The first unit that works only do auto tune in 5 to 10 mins. I would like to try manual PID, how is this done? Thanks

Hi Alex, Thanks for the input. I am yet to see this tomorrow. So far, I have not seen this status during the test. I'll try to follow yours and see how it goes. Much appreciated.

Hi, I am not onsite, and using my simulator unit. I'm checking the consistency of the PID server tool if I can use this one next week onsite. I can't see anything that I have done differently except that I RESET and INITIALIZE and start over. Now the PID server auto tune isn't working too.

Hi, Thanks guys so much for the info. I tried to RESET and INITIALIZE and then do the auto tune again using the PID SERVER, and NOT WORKING. What I am doing wrong in here? Pls advise. REgards, kvj

Hi, I’d like to ask, I’m just trying to do simulation using one of my spare unit and using memory to feed in SP and PV. I can mimic the issue I have and when I try to use the PID SERVER tool to START AUTO TUNE, it forces my program to get pass to STATUS-4. It works fine, but I’m concern when the system powers off and on, does it need to auto tune again? I tried on my unit to power cycle, it still retains the value and its works perfectly now. My main question is, is doing the auto tune using PID SERVER tool will work for good ? What will be of any possible issues later on, if any? Thanks. Regards, kvj
