    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.
  3. 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
  4. 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!

  5. 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?
  6. 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.
  7. 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.
  8. 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.
  9. 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?
  10. 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!
  13. 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,
  14. 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...
  16. 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.

    Ladder Logic Separation

    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!
  18. What the main goal is: To download a CSV file from an external source and then transfer that data into an array which will be used throughout the program. I assumed my first step was to convert a CSV file to a udtf file and then use the function "Copy column to array". However, when I try and use the CSV to UDTF my status bar always shows "-1", I have a micro SD card in the slot and a USB in another slot with the required CSV file. I also tried just putting the file onto the micro sd card but that also didn't seem to work... Am I using the function properly? Any advice would be helpful as this is my first time using Unitronics Thank you
  19. 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
  20. Hello all, I just recently began my job programming PLCs for a custom welding manufacturer, so there will be many different types of programs to brainstorm and create. I am VERY new to programming itself let alone Visilogic and PLCs in general, no past experience aside from a few linux classes before coming into this job(unrelated just my only programming experience prior). That being said, I'm learning ladder logic and Visilogic from the ground up and was hoping a few of you gurus could point me in the right direction to make my learning process a bit smoother than it'd be with just google and I. To familiarize myself and experiment with the program I am using a Unitronics v350-35-ta24(B) with the 4.3 O/S. Attached to my PLC are a few digital inputs and outputs as well as an analog input and output. I have watched all the webinars on the website 5 times through, even the ones I don't understand. It seems there is a void in tutorials between the basic introductory buttons/timers videos and the complicated vectors, strings, etc. I have somebody nearby to tell me how to do what I want, but the resources to teach myself and learn in my own way seem to be lacking somewhat unless I am missing the right videos somewhere on the internet, though I have searched far and wide, to infinity and beyond, etc. At this point I can do the basics as far as buttons, jumps, timers are concerned, my only confusion with contacts at this point is how to incorporate inverted contacts/coils smoothly which I feel will come as I design my programs and find my pace. My purpose of this post was to collect as much research material as possible that I may not know of yet, any relevant videos or forums/posts/documents about ladder logic, programming, or specific Visilogic that would help me better understand the language I am attempting to teach myself. The software is very easy to understand and work with, as well as the videos/forums that I have found so far; and you all do a great job at responding to questions on here. If anything comes to mind that might help a toddler in the Visilogic world mature a little bit it would be greatly appreciated. At this point I am really trying to master using contacts in sequence to perform AND statements, using them "stacked"(for lack of better term) as OR statements, and trying to master my motor and PID instincts. I know this is a vague request and nothing exactly specific, but any examples of simple old code you may have from when you were learning or from simple programs you had to do, websites you refer to in order to refresh your memory or thought process, or ANYTHING informational about basic Visilogic and/or programming would be greatly appreciated. Hope you all have a great weekend, Derek Godown
  21. Good morning, When creating an FTP client in UniStream, and activating the sending from the ladder program I get a response status "-6", general error. The parameters for the FTP server are correct (User, Password etc.). By testing with FileZilla, the FTP server is reachable. Can someone help me? Thank you.

    List of Text Variable

    Hello, I'm programming a table and I would like to have like a drop down menu containing food which, when the type is selected like " bananas" it is wrote in the table. It's like a predefined menu containing predefined types . I'm using UniLogic so is it possible ? ( an other question : is it possible to store a table with a name and then "increment" its name when storing the following table ( Data_Table_01 then Data_Table_02 ... ) Thanks
  23. Hello, I am having trouble understanding how the "Set Coil" and "Reset Coil" work. My understanding is that the Set coil, once energized, stay energised no mater is the RLO goes low. Is that correct? My code seems to switch off the set coil when the RLO goes low. Any ideas on where I am going wrong? Thanks, Adam
  24. Hi, I have a PID function block with an embedded PWM function which should turn a heater on and off with a duty cycle. However it is always set on (1). When I monitor the PID UDFB the output from the PWM is 0 but the main ladder has it as a 1. If i drill down further in the PWM UDFB then that is also 0. I don't understand what is happening. Any help would be great.
  25. Hi Folks, Is there any way to trigger a screenshot within the ladder? I think it would be a good feature to to have a screenshot that is triggered in the event of an alarm or other event. In this way we can put a lot of data on a hidden screen that would be captured to help in diagnosis of a fault. Regards, Denis
