balazs.tarro-HUN Posted July 20, 2020 Report Share Posted July 20, 2020 Hi! First of all I'm attaching a photo: Why are the max values equals to 1? All the curves format settings are equal and all of these are INT16. What a hack am I doing wrong??? Please let me know before I freaking out 🙂 Link to comment Share on other sites More sharing options...
Saragani Posted July 20, 2020 Report Share Posted July 20, 2020 Look for the Trend's min/max Link to comment Share on other sites More sharing options...
balazs.tarro-HUN Posted July 20, 2020 Author Report Share Posted July 20, 2020 As you can see MIN value is 0, MAX value is 1000 Link to comment Share on other sites More sharing options...
Saragani Posted July 20, 2020 Report Share Posted July 20, 2020 Can I have the project for testing? Which version of UniLogic you are using? Link to comment Share on other sites More sharing options...
balazs.tarro-HUN Posted July 21, 2020 Author Report Share Posted July 21, 2020 UniLogic V1.29.111 USP-156-B10  I'm sorry it is not allowed to send my project file. However I've some USP-070 PLC in stock, I'll try trends on it and send some news Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted July 21, 2020 MVP 2023 Report Share Posted July 21, 2020 balazs, in your screenshot your item #2 (linked to TB1) is not 1000, it is 1500. Does changing it to 1000 make a difference? Also, have you actually got some values in the plc for it to work with? cheers, Aus Link to comment Share on other sites More sharing options...
balazs.tarro-HUN Posted July 21, 2020 Author Report Share Posted July 21, 2020 I've tried severel values without any differences. °C units = Thermocouple with current transmitter 0-1000 °C 4-20mA Pa units = Differencial pressure transmitter 0-1500Pa 4-20mA Yes, the values are linked to analog inputs with live values. It is a working system and I still don't understand why it happens 🙂 despite of I've done severel unistream projects with trends, data tables, email and so on. I am confused now  Link to comment Share on other sites More sharing options...
Saragani Posted July 22, 2020 Report Share Posted July 22, 2020 Can you save-as the project, then delete all ladder code, and all other HMI Screens (and all the things that are irrelevant), and leave only the Data Sampler? Then you could share the project because it does not contain anything secret. Link to comment Share on other sites More sharing options...
Daniel_EWW Posted July 23, 2020 Report Share Posted July 23, 2020 Do you have an SD Card inserted? Each Data Sampler has a global data struct. You can look at the status integer of the data sampler if there is an error. (Enlosed a trend printscreen without inserted SD card) Link to comment Share on other sites More sharing options...

There's a reason we ask for the project file. It's difficult to troubleshoot a more complex object like a Trend without it. This thread has been going since Monday, and I'm sure you're frustrated. Post your Data Sampler information for the Trend. Joe T. Link to comment Share on other sites More sharing options...

I was on a new project launch and I didn't have any freetime either energy to reply 🙂 Yes, I've inserted SD card. This is the first step after unboxing (it is necessary to update firmware what is my step 2) By the way I've just noticed a strange thing: is that normal if Sample Interval value equel to 0 in spite of that I set it to 10 seconds at the data sampler preferences? You can check it in this print screen: (You can also see the live values of the analog inputs)  On 7/23/2020 at 11:43 PM, Joe Tauser said: There's a reason we ask for the project file. It's difficult to troubleshoot a more complex object like a Trend without it. This thread has been going since Monday, and I'm sure you're frustrated.

How do you mean to forcing an update? Need to start the procedure again? I'm just doing some logic to send emails. What are the issues? Link to comment Share on other sites More sharing options...
louisgermain6 Posted August 3, 2020 Report Share Posted August 3, 2020 Hey @balazs.tarro-HUN Last week I had the same issue with the trends and another one sending mails. I contact the support to have some informations about it. Figured out that they didn't knew why I the sending mail status was always remaining to 0. But then they suggested me to force the update of the PLC. You can force an update going to unistream management in Unilogic and by clicking on remote update. I'm not 100% sure that it will resolve your problem, but it resolved both of mine. Â 1 Link to comment Share on other sites More sharing options...
