  1. Dear Sir, I am using V1210 PLC How to convert MF (Memory Float) Value into MI (Memory Integer)? My MF values will be like -0.0023, i have to use this value for plotting graph Trends. But the trends having only option to link vector operant MI only. Here, i dont know how to convert my MF value -0.0023 into MI. Or do you know any other option is there to use my MF value to plot Trends? Kindly help me please.
  2. While watching the online tutorial for trends, I have noticed in my software an additional field required for setting up a trend, which is not included in the tutorial. I am being asked for a "trend description operand". I've already entered a description, what is the use of "trend description operand"?
  3. I use trends and they fill up the SD card on the UniStream. I tried to use the file browser object to manage the SD card. Specifically I'm trying to delete the 'samples' folder created by the trends. When I try using the file browser and UniStream SD Delete (or the one in UniApps) after selecting the 'samples' folder I get an error Any ideas on how to do this correctly? Is something writing to the disk or not properly stopped? Right now I have to pull the SD card and delete it on my laptop then put it back into the PLC. Not very elegant and difficult to do remotely... Thanks!
  4. Trends Scaling

    Hi - I was wondering if there is a way to auto-scale the trends, instead of min value and max value you would set it it auto and it would automatically scale based on the data set when displayed. Thanks.
  5. Dear Community, How do I see two (or three) trend curves at the same time as seen in Visilogic? Thanks All! Sincerely, Hotwires
  6. Hi I have a project with USP-104-B10 (UniStream 10 inch) ַַ& Unilogic 1.15.70 and in the project I build a trend screen. Now I have to save the data into the SD card ,transfer the data to my computer and convert the data to csv and generate a graph. It's a very long process. how can I shorten it? can I save the data straight to csv? is there a software that can take the data format of the trend file and make a graph?
  7. hello, i need to monitor a square wave of 3V amplitude and 190 Hz. can i display this signal on HMI trend graph? what extantion do i need ? analog input ? i am using V570. thanks.
  8. Iv'e set up email and it seems to be working OK but attachments aren't being received in the emails.. I've taken some screenshots from the trends button.. the attachments show in the file browser but they aren't being emailed for some reason. Any suggestions?
  9. Export Trend File to CSV

    Hello, (Unistream PLC and 10.4 Inch screen) I Try to export the trend data from a Datasampler to a CSV (EXEL) File I get it from the SD-card with filezilla. Sometimes the file will be generated and sometimes it won't I stop the data sampling and then i set the create CSV bit. in ladder function. But it not always generate the file (.ZIP) Is there an example how this file must be generated. I use Unilogic version 1.9 rev 19 I have tried a full download and so on but sometimes it works sometimes it won't Is there any example how this works. Thanks René
  10. Hello, I want to use in my application controller HMI touch panel UniStream. I want to measure the three analog values, and visualize it on a graph. I want to connect the printer to panel. Can I print these trends? What functions to use to print my trends? Marcin
  11. Hello, I am working on a project that requires recording the trending data from 4 separate trends to the SD Card. They want to record the data "no less than once every 5 minutes". I based my code off of the program in the examples file in the help menu and was able to get a single trend screen to record (I did it on the v570 for testing) based on a series of timers. The code worked fine however when I used the identicle code for the v1210 (setting up a single trend screen for recording) my start->trend SD Status message reads 256 which I assume is "failed to open file". Does anybody have any pointers on getting the trends to record to the SD card for a v1210? I would export the subroutine and attach it to this post but it won't let me export due to "elements that refernce Named Constants"
