  1. Is the help topic "LF: Write Value to DTI column" referring to the toolbox item "Set DTI Column Value"?
  2. Hello, i have a question regarding the file name in a store dti to file function. i need to create a new file every time i run the function which is set to happen every day at 6am. is there a character restriction in the target file name string? i would like to utilize the dd/mm/yy string that the RTC to ASCII V2 function creates as my file name if possible. at this point i am pre planning a project and do not have a physical controller to test. thanks ricardo
  3. I like to link different Data Tables (Indexed) to one Function as IN parameter. Has someone done this already? What I'm doing wrong? (Please see example Function1 Rung 1; Direct linking is possible Function1 Rung 2)
  4. Anyone want to attempt to interpret this warning alarm? "Inserting rows to an 'Indexed Data Table' when the insert index in a small number can increase scan time and cause a CPU Watchdog." Is there a typo in the message? This warning didn't exist in an earlier version of UniLogic and I'm not sure what to do about it.
  5. we are trying to use a plc to connect to the network so it can automatically reload a data table periodically to make sure it is up to date. As well as how to have an excel sheet be converted to a udtf format for the plc so that we don't need to manually do that each time. I am currently only finding how to load files from an SD card, and not how to use the Ethernet connection to retrieve files.
  6. Partners, I'm having trouble moving information from one DATA TABLE to another with the same structure. The structure of my data table is as follow: Floor/number/day in/month in/year in/day out/month out/year out/hour in/time in/hour out/time out/money/quarter When a specific event happens, program calls a function that saves date and time (year in, month in, day in, hour in and minite in) in specific place of data table index A (this way I know where this event happened, becouse the first two columns on the table are the reference of the place) In table A the first to co
  7. Hi, I wanted to know if there is a possibility to attach a date table in an email. Please, I would greatly appreciate your response.
  8. Hi Everyone, I'm new in Unilogic and I would like kwon how to export data tables to Excel since a HMI button. The PLC reference is USP-104-B10. Please, it's urgente.
  9. I need to send a DTI Column into array, but UniLogic help is not clear, please could you give me an example of ladder logic ?
  10. Hello all, I'm pretty new to controllers but I have done some research around. I have sensor data, along with real time data that i'd like to store in a data table and transfer it once a day to my PC. The sensor works all the time, so i'd like to store sensor data every 60 seconds inside the table, and one a day (1440 lines) to send it as a .csv file. My local Unitronics supplier suggested my to get USC-B3-T20 for this application. Problem is that the data table stays empty for some reason, information won't push into the table. Please see attached photo of my project and a
  11. Hi, I'm trying to build a log for my system using the Store DTI to File function. This runs after the struct containing the date is inserted into row 0 of a table, which should be appended immediately to the log file. The writes are sufficiently spaced (~30 minutes) that the SD write interval isn't an issue. I've found that when using option 2 "Only CSV" for the "Create CSV" input (F), the file is simply overwritten, and only ever contains 1 row. Option 1 "Create CSV File (All - udtf,csv,csv.zip)" does append correctly. In both cases "Append to File" (E) is set to 1 "Data will
  12. What is the most efficient way to store date and time in an excel table so that it is easily view able in Excel? I converted it to a string, but the strings take up too much PLC memory. Excel can't natively interpret Unix time, so that won't work either. Is there something else Excel can interpret that I can store it as?
  13. Dear All, I am doing as follow: import a CSV file (copied from USB stick in the "data folder") with a single row of 23 Strings (each String is 25 lenght); create a UDTF file from this CSV; upload the UDTF to a DTI; read the DTI row. each of these action is done in a specific ladder rung; each rung check if the previously action was perfomed without problem...then at the end my CSV is converted; the DTI il filled with right values but when I read the DTI row I don't have any error (exist status "0") but the struct variables is not filled (all single field is empty)...I tried to write
  14. I have a 480 Data for every minutes Now I want sum it up and divided by 8 hours average? How to sum up all data from data table and how to sum selected data for example 1st 15 minutes data average
  15. Hello. Am programing Unistream PLC model USP - 070-B10/B08. The program i need to make is User Logs with Data table. With UAC i add needed users also am making Data Table indexed and am writing the logs (log in or out ) into the data table. Also there is a possibility to enter in the HMI the batch number/lot that is later added to the Data Table depending on the user who is logged in at the moment. After that with a button on the hmi i set bit and Store DTI to file block is added. As i can see everything is good and this DTI block does not give me error. After i open the ftp server the
  16. Dear Sir, I'm using UniStream PLC and I have log Data to data table and make data table Retain. i have problem it that Data table row is limited for retain Data because data table save in RAM. How make data table directly into SD Card? And any way to show Data which in SD card directly HMI Data Table?
  17. Hey, Each day we want to start writing data to a new file. Our file name string is updating fine using the rtc to ascii UDFB, but our store DTI to File status turns 1 when the filename is updated with the new date. Then after another full "day" it becomes -35. However if we never change the filename the data recording continues to work fine. I apologize if this is already explained in another forum but I wasn't able to find one. Thanks for any help your willing to give.
  18. Hey, What is the best way to get a column to show the Date and Time information? Right now I have a separate column for each feature like month, day, year, hour, min, second but that's definitely too bulky. I can't seem to find how to create a single string of the date and time information, what would be the best way to solve this? Thanks.
  19. Hello, We are able to log sensor data to the data table, we record it once every 5 seconds. However, after 10 recordings we are trying to write the 10 lines to a csv file. (Ideally appending it) Firstly, appending just doesn't work (when we put the 1), the file doesn't update at all. When we put 0 to override, the values go in but only one and a half rows. Any ideas? Thanks!
  20. Dear All, I have a Struct that have 13 variables (String, Bit, and uint32); I created 4 global variablea to record these datas; I have created a DTI with a single row to take these information and save into a file if some event arise. When the event arise I don't have to record all the informations as these are but I have to modify a litte; then when the event arise I store one of the global struct into a local struct (same struct) , write this in the DTI and copy (append) this DTI in the file (already present). what I have is that if I use a LOCAL struct the data is store with
  21. Hello, I am attempting to create a system in which every time someone rings the wireless door bell, it communicates with the PLC and keeps a log of the time and date at which the button was pressed. I am almost done, and only need assistance when indexing down a row (copying the data from the previous row and writing it to the next). I see there is a indexing row tab on the button, but i need help understanding the function in and out tabs and how to use them successfully within my program. Any help would be appreciated. Thanks, Michael
  22. So I am a beginner when it comes to not only unitronics software, but PLC's in general. I am tasked to connect 2 door bells (one in the front, one in the back) to the PLC and create a program that once one of the buttons has been pressed, it sends a signal to the plc which activates a horn and tower lights (depending on the door). My problem is creating a data table that acts as a log. It is supposed to keep track of - 1. the time when a button is press, and - 2. the date. Also one other question, the timer off command doesn't seem to work in my programming, which is supposed to tu
  23. Dears All When I create a DT I have to referred this at a specific STRUC; when I save this DT to a .csv file the "column" will take the name of the variables; exist a way to change the column name's? I mean...for example...usually my project include Italian, English, French and Dutch languages because who, usually, committed me the jobs has customers in different country...what I need is if I have a struct variable like: myStruct.hello the column in the csv file will be, referred at the language selection, "hello" or "ciao" or "salut" or "hallo"...is possible without create 4 differe
  24. dears All, I will have to modify an old project where I used a lot of retained tags (was my first project and I was not very skilled...for sure worst than now 😁 )...I want to replace the retained tags with a struct referred at a DTI...then save this on the SD. my question is...if I will upload a new project , the same but with more UDFB-tags etc, the retained tags that are used at the moment still contain the same value or will be reset? just to know if I can do this without problem, because I will also update the PLC version, or if I have to think something to save the retained
  25. I'm having a problem with the data tables in a UniStream PLC. Sometimes one column of the data table had been shuffled randomly. Does anyone know about this problem? The data table is retained and battery is OK.
