Arunrajput Thanks for adding datas here. Could you send a " correct file" I mean Displayed horizontaly for the TNR block. I tried to open it with another "file viewer ", but it is impossible to read it clearly. Also on the rung ( that you posted) output signal, is not clear we cannot...

Ok Looks like I helped/supported you a lot by providing such infos ! BUT you could at least by "courtoisy" try to reply to my post ?? I make effort for supporting people here and some of them are just stonish §!!! Controls Guy25

Carlos Duarte, Thank you so much for this studies results. My first question before to forget is did you find the " lost inertia " finaly? The method you are using, for RoCof Calculation seems quite good. Can you please , tell us how you can disctinguish that frequency is recovering at...

Gopinath, CSA, CSA have pointed a good thing, about an eventual mistake on pressure transmitter designation. Gopinath, Thank you for the datas you added here. My first impression after seen trends and trip/alarm log list is that 2 FSR REFER TEMP ACTIVE are shown in the list at 10:03:56...

Hello All, Gopinath, First could you tell us, the reason why you forced these signals. Did you get the P2 pressure, behaviour trended ?? Are you listed on your post all "alarms /trips" messages? We can try to support, you if you tell us more details on this issue. By better event...

Hello Rizu, We could try to give you some support ! The informations you have provided seems ok! My first comment is that the schematic is not completed?? ( i mean Stepper motor and sensors are not shown??) Did you even check on some videos on the web?? I just have seen some interesting...

Thank you for answering. Well It would be difficult to perform, such troubleshooting remotely from here and without datas/informations . Resetting logic board, without knowing reason/cause of the "Issue", is not good at all! Is that module is coming, with Master fuel trip or over equipment...

Hello Asabula, There is some misunderstanding, of the issue you try to describe. We do not know what kind, of "fault" or "error message" that the system is eventually displaying. Also if you could share, a schematic it would be helpful to get better overview . What are the results after...

From a first impression, it seems that IO2 DIOE module is not properly configured. Did you ever make some kind of modifications/updating /??? last days ( I mean before getting this message)? Without knowing type/model of the controller and HMi, we can not provide better support. Its like...

Hello All, Hochelaga, Quang Doan, Can you provide us some feedback, on the issue you have been faced (dicsussed on this thread). We can try to support you as best as we can! Regards, Controlsguy25.

Hi Labib, When did this problem appeared ( any known reason)??? Also do you got OEM documentation ?? ( user manuals, Opreation&Maintenance manual ....) We will try to solve this issue, as best as we can. Many posts here about Elektonikon, have not get solved but lets try ! However I found...

Check out these two interesting tutorial, for how to modelize fuel pump in matlab . https://fr.mathworks.com/help/physmod/hydro/ref/centrifugalpump.html https://fr.mathworks.com/help/physmod/hydro/ref/centrifugalpump.html After that you have bunch, of videos explaining, how to do frequency...

You can check, on the document that i posted here. It can help for getting a plant model.

Thanks for your reply, Actually I am not sure, if the mentioned PLC have kind of functionnality or extension module, for executing the frequency response. I will keep you updated on it. Also did you check, on Matlab simulink if it can be a solution for your studies?

Hi ILC_H I am not sure of kind of tests you want to do?? Is that for vibrations analysis ?? or other studies??? There can/should be extension modules, which can be connected to plc . You can try to check, if Matlab simulink got PLC interface for that tests . Let me have a look, on the...
