  1. 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!
  2. 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
  3. Hi. How can i change a data table fields using c function? Can you please send me an example?
  4. Im using a unistream 7 to communicate over serial with a pump. I am able to set settings over using the COM Tx and Message composer, however I am encountering issues with the COM Rx command. I can set rates and volumes without a problem, however I want to also grab the max rate and volume from the pump at the start of the app or when a user pushes a button. I should be able to send "read limit parameter", which then returns the max rate, min rate, max volume, min volume, The following is the return from putty. read limit parameter 29.12145 0.00010 29.31703 0.00269 > However it
  5. 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
  6. 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?
  7. 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
  8. 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 f
  9. 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 n
  10. 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.
  11. 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
  12. 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!

  13. 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?
  14. I'd like to suggest a column to disable or enable the action in pictures when i press. The same way it is done in the alarm group. Regards, MAuro.
  15. 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.
  16. 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.
  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. 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?
  19. 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.
  20. 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
  21. 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
  22. 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 struc
  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
  25. 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...
