  1. Hello all, this is the first time I am writing to this forum. We were using vision plcs and now is the first time we are using unistream. We have connected the cards through USP-TCP. For the analogue input we are using the card URA-0800O and we set the input 4-20mA. The sensor we are using is 4-20mA 0-150oC. We tried linearization but the output value is wrong. In X1 we entered the value 818 and X2=4092. in Y1 we entered the value 0 and Y2=1500 but the output value is 0 and does not change. When we change the Axis values (y1=818,y2=4092,x1=0,x2=1500) in linearization, shows an output value but is 10-15 degrees less than the actual temperature. Are we doing something wrong? Thanks
  2. Hi guys. I try use local integer variable in UDFB with inc block, but not work. I know not possible monitoring a value on line, but i connect in function out in the block and not change values outside . The inc function not work in blocks with local variables? Regards
  3. Hi! I'm programming an UniStream Modular USP-070-B08 + CPU USC-P-B10 with UniLogic v1.25.61. I want to create an array of INT16, which its length, will be set by the user through the HMI. Is it possible? Because when I create the array in Ladder, I can only set a constant value for the array's length. I want to try something similar with the number of rows for a table. Thanks in advance!
  4. I have used the UniStream in 2 applications and I am a fan. I would like to know if you can edit your ladder and do a download while the PLC is still running.
  5. I need to calculate the difference between the current tag value and its value during the previous scan. The tag value originates from a Formula using analogue data from a UIA-0402N Analog input and stores a Real value. Is there a easy way to do this without using a Data Table or other FB that uses the SD card memory?
  6. I would like to clear all the data in a certain struct. I thought I was able to do that using the Reset Numeric function. I entered the name of the struct in the function box tag and then erased the period. For some reason, however, the data is not being cleared in the struct. Am I wrong in how I set this up, or am I overlooking something?
  7. 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!
  8. 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?
  9. 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.
  10. 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
  11. 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!
  12. 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
  13. Hi. How can i change a data table fields using c function? Can you please send me an example?
  14. 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
  15. 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?
  16. 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
  17. 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
  18. 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.
  19. 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.
  20. 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
  21. 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!

  22. 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?
  23. 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.
  24. 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.
  25. 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.
