  1. 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!
  2. HI everyone. I have a Unitronics PLC with HMI USP-104-B10 I have a Flow meter connected to one of the Analog input cards and it sends out a flow rate, I want to calculate the total flow in cubic meters and display it on the HMI, I also want another display with Weekly Flow ( so it uses the same logic and calculations of the total flow but should reset every time the operator pushes a reset button after he takes his readings). Both The Calculations are the Exact same logic the difference is they are assigned to different tags. But the readings are completely different and random.
  3. Dear All, I am having a strange issue...I try to explain, I am checking the serial communication between a master and a slave (modbus rtu...like a sniffer) and I am using the Unistream to catch the exchanged data...at the beginning, as first test, I record every 10 bytes and save the buffer in a DTI...and all has works fine...now I want to take the exact request/answer between master and slave....then the first record is checking the 8 bytes...the data will be, for example, 1-3-0-216-0-3-134-56 (the CRC is not calculated...I wrote only as example)...then I want check the position 5 in the buffer (3) to know how many bytes will be the answer...in this case will be (3 *2)+2 =11 bytes...I am using the function block buffer to tag to store the buffer[5] and do the calculation...I tried to save the specific buffer position to a single tag and all the buffer in an array...both UINT8 and UINT16 but...but this never works....in the position C of the function block is wrote that if the end tag has not enough space the function will not execute...but I don't think that is the problem...what cna be the cause? What I am wrong?
  4. 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
  5. I am working on a project that requires an operator to enter a field (on the HMI Screen) by scanning a bar code. I want to be able to confirm that the scanned field has a specific number of characters. The field is linked to a tag that is an ASCII string. It will be an alphanumeric string 25 characters long, and I want to confirm that the scan in fact inputs all 25 characters. Any thoughts on how to do that would be much appreciated!
  6. Hi. How can i change a data table fields using c function? Can you please send me an example?
  7. I'm with this UniStream 15" , where is with one routine and i declare bit initial cycle. The problem is he is blink after power on , during all time. I do not know what else to do. WhatsApp Video 2018-10-30 at 06.14.44.mp4
  8. Hi, I have a UniStream application where I would like to disable the alarms for ~10 sec or so after a power up. Currently I get nuisance alarms after a power up, since the UniStream application seems to check for alarms before the transmitters have fully powered up. Is there something like a "first scan" bit and a disable alarms bit?
  9. Hello, We have decided to swap our PLCs from Vision (VisiLogic) to UniStream (UniLogic). And so i've stumbled upon a challenge. I want to load a timer which is a timer from the HMI (keypad entry) and store a timer from ladder to HMI. In VisiLogic I were able to load a timer to an memory integer (like shown on the picture). But how am i suppose to do this when I don't have this function available? Regards Sander
  10. Hello, I'm new to Unistream so forgive me if I misunderstood something simple (I use latest UL version and latest firmware on PLC). I wanted to convert number in string and found out that UniLogic doesn't have Num to ascii function. Not happy, but OK, I found UDFB in samples library and set it up according to my needs. Then I encountered problem : I want to set output string to be 4 characters long, show +/- sign and pad zeroes to fit 4-char format ('+007' for example) UDFB works fine until I switch PLC off and then ON again. I noticed that in my ladder progrem UniLogic CHANGES UDFB format (padding) selection from 2 (pad with zeroes) to 1 (pad with spaces) I cant figure out why UniLogic changes UDFB input parameter by itself??? Even stranger is that downloaded program "works" until power off. After power On PLC start to pad "spaces" instead "zeroes" and when I open Unilogic program there is also format in UDFB set back to "1" -pad with spaces. attached pic. UDFB input parameter D should be "#2" for my needs but somehow it comes back to "#1' Thanks for help, Regards, Marko Kocijan

    ML value to a String

    Hi All, I want to take a value from ML[1] which is 70,511 and make that into a string, how do I do this in UniLogic? Thanks, Don

    Parallel programming

    Hello, I'm looking for a solution to run 1 function multiple times at the same time with different values. I've already made a function with local tags, function in tags and function out tags. Inside the function is a small calculation and a short delay, divided in steps. I think the timer is the biggest problem, how can I solve this? How can I make a timer a local tag? Thank you in advance.
  13. Dear colleagues, I've one project where I need to read from TCP/IP port ASCII string from COGNEX Insight 7200 camera data. We are reading standard ASCII characters but also we have CROATIAN characters which are not represented in ASCII (ČĆĐŽŠ). I decided to use UNISTREAM 7" PLC for this purpose but I'm stucked with the way how to do this, I'm new to the UNISTREAM. I red in forum that we can use function COPY BUFFER TO TAG but when I do that I got ��਍. I can teach COGNEX camera to save font Ž as # for example, so if camera reads PŽ1234, it will send ASCII string P#1234 to PLC. At PLC side I need to convert # to Ž and then compile it to original state PŽ1234 and send it to SERVER. Can anyone help me with this ? Regards, Sasa Jovanic LOGOKOD d.o.o. Croatia
  14. Hi, I have a problem. It's the firt time that I work with Unilogic and I need help. I have to divide two numbers, that gives me a comma value as a result. I do not know how to handle values with commas in Unilogic if I have to set REAL values. On top of that I want to put the result value in a timer. Is it possible with this soft? Thank you!

  15. I'm having a problem with compiling the program. It gives an error because one region does not have rungs. I can't put some rungs in the region and can't delete the region. How can I solve this?
  16. I wold like how to make two interger in single variable , with pointer index ? Example int 1 (bin) = 1010010101010101 int 2 ( bin) = 111111111111111111 start index for 2° int : 16 position result : 111111111111111_ 1010010101010101 In VisiLogic have block for this ( vector fill) . But in unilogic not found this. You can help me. Regards , mauro.
  17. 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.
  18. Hello, is there any way to debug this? On the picture there is function, which went blank. But actually there are rungs with Call Func" commands for another functions in the program. The "Call Func" logic in the program loaded into PLC works, but the function in program is blank, and cannot be deleted or written into.
  19. 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?
  20. 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.

    Data Tables on a Time-Loop

    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.

    Unilogic Schedule

    Hello all, Still working on a program to monitor the park's water system, for one of my actions I believe I need to use a Schedule setup. From the documentation and toying around I believe I did it correctly but wanted to verify if anybody has a moment to let me know. Working with a Unistream 5" RA28. What I'd like to do is... Every Wednesday, between two user-set times, activate a normally closed relay. The times would preferably be retained through the week if possible. A part that I was confused about is that "Wednesday" is specified in the System/RTC Date/Day Of Week struct, however you can not click past the struct shown in my second picture, so I was surprised when it was an option in the logic portion. Did that come from the system struct that I'm assuming it did and was just hiding since it cant be edited by the programmer? Am I on the right track here? Hardware is on site so I cant test it as thoroughly as I'd like until I connect, just did this quickly this morning and wanted a pair of experienced eyes if they're looking. Happy Friday!
  23. Hi, I was a very basic ladder logic question. At the moment I can only force on outputs on from the PLC . My latches do not seem to be working correctly. When I activate the start pushbutton when in online mode the green light output is not activated. I know the output works when forced the output to a 1 the green light turns on. Sorry total new to PLC programming and just trying to get to a handle of it. Any help at all would be great. Thanks,
  24. I have outgrown the Jazz2 and wanting to upgrade to a Vision 130. The Jazz2 Ladder program has become fairly complex over years of development and upgrades. I have only moderate programming skill. Can the Jazz2 Ladder program be easily converted to run on the Vision 130? I realize the the HMI screens would all have to be created for the Vision but could the core ladder program just be copied and pasted? Are the System bits of the Jazz2 compatible with the Vision series or would they need to be cross referenced and changed? Thanks in advance, Rob

    Button color via ladder

    Hi, I am new to this. Is it possible to change button color via ladder? Or after pressing it to change color? (for example I want ON/OFF button to change text and color... or maybe just color to indicate it's on or off) Also is it possible to change attributes at all via ladder? I know there is a way to hide a button and show another one of differnet color, but that's not what I want...
