  1. Dear all i have a problem in HMI it gives an error of stop mode plc how can i reset it or jump to run mode
  2. Hi. How can i change a data table fields using c function? Can you please send me an example?
  3. 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
  4. 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?
  5. 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
  6. 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
  7. The majority of my current applications involve Load Cells. I currently use V350 and/or V560 with an EX-A2X expansion adapter to an LC1/LC3. I originally used EX-RC1 but deviated from it and use exclusively EX-A2X because I can email and explain to any customer how to upload clones for any specialized changes I make to the V350 and V560. Since you need to be physically plugged into the EX-RC1 to do any upgrades its usefulness has its limits. So My question is what is the easiest way to utilize load cells if we do make the jump to Unistream line of PLCs? I'm really hoping my options are not limited to CanBus to EX-RC1. At least it is an option, but I would likely add more Analog I/O to the same location, which goes back to making changes a bit more difficult. I know there are other ways to upload a program to the EX-RC1 but Internet connection is not readily available at all machine locations, and having a guy on the other end of the phone with any amount of programming knowledge never happens, so the less I need to walk someone through how to use a computer the better. Plus the machinery moves and most plants don't want to take the time to plug the system into their router, let alone properly set up a network.
  8. 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.
  9. 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
  10. 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!

  11. 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?
  12. 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.
  13. 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.
  14. 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.
  15. 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?
  16. 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.
  17. 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
  18. 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.
  19. 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!
  20. 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,
  21. 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
  22. 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...
  23. Hi, I was just wondering is there any way to separate my code like an "if else" statement in C. For example. If a condition is met, I would like to run only a selection of 10 lines of code and if the same condition is not met, I want to run a different 10 lines of code. Thanks in advance!
  24. Hello I am fairly new in UniStream and still can't find my footing. What I want to do is to store file first into CSV on SD, then to UDTF and later to read the UDTF file on a Data Table. But, when i try to convert the CSV into UDTF I keep getting "-4" as status. I tried this function on the example for Data Table, with me first making a csv file with "Store DTI to File", next trying to convert the made file into UDTF, but the end status is "-4". I have read the CSV file on the computer, and it has what the original UDTF table has, so that should not be the problem. Is there something I am doing wrongly? It would be great if someone could advise me on this. Also, after rereading many times the help file, I have this question: why can't one write '0' for "Parameter E"? I agree, that if one converts the csv from a created file with "Store DTI to File", one should for sure delete the first column, so that the table could read the new UDTF. But what about if one makes a CSV file like the one in the "Log to File" example in the "UserLogs" folder? I have attached the added rungs on the "Indexed Data Table" example I made. I am using USP-156-B10. On the example HMI, I have added 2 buttons: 1st for Storing as CSV, 2nd for converting CSV into UDTF.
  25. Hi everyone! Is there any way to set the PLC to RUN/STOP mode via ladder code? I want to have a button (it could be a physical one using one input) that once you press it, the PLC goes to STOP mode (every output turns off), and if you press it again the PLC goes to RUN mode and keeps on working like it was before stopping it. Thanks in advance, Gonzalo
