  1. 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 "wrong value" (strange characters) and also the last value that is a BIT is stored in a 14th column in the csv file that don't exist; if I use a global Struct (convert the local to global) all works. I don't tried to "reset" the local Struct, to inizialized, before populate it...but until now (other projects), if I well remember, was not necessary. I am using last version of Unilogic 1.26.
  2. 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
  3. 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 turn off the outputs after 5 seconds. of being activated, Thanks, I know it is a lot but any help would be appreciated.
  4. 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 different struct?
  5. 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 tags and upload these later. thanks
  6. 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.
  7. Hi all, I could not find a clear answer to my question in help files and the forum so I will ask it in here :] I'm trying to use "Recipe table" for a first time. This is probably a simple thing but could you explain me, please, what is the difference between a "Recipe table" and a "Indexed data table"? Can I load information from recipe file directly to variables (with struct), or is it necessary to load recipe data to indexed data table first and then read the values (Read Row from DTI) from data table? In what cases recipe table has advantages against indexed data table? When is it better to store the information in DTI file and when is it better to use recipe file?
  8. I'm recording daily rainfall in mm to a datatable. How might I go about setting the decimal place in the data table to a resolution of xxx.x mm? Is it also possible to hide the # on the HMI data table display? Developers: It would also be nice if we could adjust the Row Heights as well... TIA
  9. This is my first unitronics program. I want to control 6 motors to multiple sets of pre-set data (probably 50 data sets). My idea is to have all pre-set data stored in the Data Table Recipe. Once a data set is selected then got assigned to Data tables to execute the program. I am struggling with the data set selecting GUI. I don't know how to create either a list box or what which can display all data set saved in the Data Table Recipe. Any suggestion or example I can look into. Appreciated.
  10. Hi, Where do I find how to change the data table font size appears in the HMI screen?
  11. Hi All, I have a Data Table with fixed values that by reading a row and a column I can load a certain value into a program. I have set the Data Table to be retained and when I power down and back up all values are still there. - What happens when the PLC battery dies? Are values in the Data Table still retained? - There is the option to save the Data Table to SD card. Is it possible to load a Data Table, complete with values, from an SD card into the PLC on power up? Regards, Denis
  12. Hi people! I'm developing a project with UniLogic v1.25.61 for the UniStream USP-104-B10. I need to sort an entire Data Table (2 columns, A and B), sorting just one column (A), has anyone ever try this? The other option is to have 2 arrays (A and B), sort one (A) of them and then I need to sort the other one (B) the same way I sorted the first one (A). I don't know if I'm being clear enough so here you have an example: Before sorting: A={1,4,2,3} B={Q,W,E,R} After sorting just column A or array A: A={1,2,3,4} B={Q,E,R,W} Thanks in advance! Cheers, Gonzalo
  13. Hi All, I'm storing data in a Data Table. Once a day I write the data to a file using the "Store DTI to File" instruction. It all works well and a file is created. I'm then using Excel VBA to read the data in one line at a time. The issue I am having is that the CSV file has comma "," separating the lines. How do I get the Unitronics software to install a line break after each row from the data table?
  14. I have a large Data Table (Indexed) that I need to rearrange the columns. According to the online tutorial that can be done, but it doesn't explain how. It also doesn't seem to be addressed in the Help file. None of the common sense ways seem to work. Anyone know how to do this in UniLogic?
  15. Dear Sir, Please help on following DTI usage. I am using EXCEL sheet as attached for showing volume of tank. We have 2 conditions. 1. NEGATIVE TRIM 2. POSITIVE TRIM. trim is calculated by our sensor. The height of the liquid is also calculated by pressure sensor. From the liquid height according to positive or negative trim, select the volume from the cell. This value want show in a numeric box. For example, I know my tank list is positive and sounding is 0.25 and trim of 1.5, as per excel sheet my volume will be 5.12 Metric cube. Want to pick this 5.12 value and show in numeric box. if in negative trim, at 0.25 depth and negative trim of 1 my volume will be -0.67 metric cube. From excel sheet how I can select using DTI I marked it red for ease of reading. Can you help on this please. I have limited access to internet. cannot search and study the examples. This will be great help for me. With regards Attachments area NO1TSWBP.xls
  16. I have a DTI in which I want to search a column for a string with a specific prefix. The column contains strings of 25 characters each with a unique 3 letter prefix. How can I perform a search returning a match for a given prefix? In other words, I want to return the string with prefix "ABC". Thanks in advance!
  17. Hi, I'm using the PLC usp-070 and trying to use data table. I have an SD card in the PLC and: when I use the function "store DTI to file" I get error status '-31' when I use "load DTI from file" i get error status '-4' the SD card is FAT32. I'm new with UniLogic and every help will be appreciated. thanks, Moran
  18. Hello, I want to change the number of digits that display after the prescription point on real value displayed on data table all the real values prescription points displayed with 6 digit and take lot of area in the Data table
  19. Hello, I'm working on a program that save multiple values in a data table and at the same time in a CSV file every 200ms. Every thing is fine when I look at my data table in Unilogic, every value is saved there every 200ms but for some reason, on the CSV file, the data from row 0 to the current row is appended again every 8 seconds or so. I can add my program if anyone can look at it. Thank you
  20. Hi, My application Ladder code writing to an "Indexed Data Table" (DTI). I'm getting in the writing "Store DTI to File" Ladder function the status (-6) which means "Write file error". I think that issue is coming from the speed of "Store DTI to File" calls. I use a timer to put a delay between every row, maybe i don't know how to use them, but it doesn't work for me when i put a timer and try it online, it doesn't work.
  21. Hey guys, I need to store files through the "Store DTI to File" Ladder function, but the more complicated is we need to generate them everyday ( everyday we have a new file ) named with the Date and Time it were created, and same for files that contains information for a month. To make it brief, at the end of the month, the SD should contain about 30 files for the daily information, and 1 file for the month. Do we really need to use the "Schedule" Ladder function?
  22. Any help on using the block for reading the data from data table into SQL rows would be appreciated. I could not find enough document on using this ladder element in the help section. I can read successfully execute the query and read the data from the database to the data table.
  23. Hello all, I'm working on Unilogic with a US5-B5-RA28 on version 1.23.25 My overall task is to monitor water usage from a pump house to an entire industrial complex. Part of this involves taking readings by time increments. The user would like two different displays, one every 6 minutes with 10 readings per hour. As well as one every hour, with 24 readings per day. I have two questions about different aspects of data tables, an answer to any part of this post would help tremendously. First, how would one construct a looped timer to trigger a push and/or pop function every x minutes depending on my reading? I will attach my logic below with my attempt. Lastly, is there a way to add the values that are in my data table? For example, the user would like the sum of all 24 hourly readings displayed, and on the new hour, pop a value and push the next value, affecting the sum however it may with the new value. That way, no matter what hour he looks at it, he has his last 24 hours of water use in front of him, same idea for the hourly sum, adjusted every 6 minutes. I am still very novice so please excuse my poor labeling or obvious oversights if there are any. I watched the webinar and read through the help files a few times, but could not find specific enough examples to finish my attempt.
  24. Hi, I change a battery without saving table date. How can I restore the table date?
  25. Hello, Is there a way to add in one file a screenshot from the Data Sampling with the data from table? I know there is a function of Data Sampling creating a CSV file, but I need the information of the CSV file to be together with the graph/s, ready for printing. How can I implement that? Do I need to make it into text file, or should I use the "C function" option, or is there something else? I would be grateful if someone answers, even if it is a negative answer.
