  1. Hi, I wanted to know if there is a possibility to attach a date table in an email. Please, I would greatly appreciate your response.
  2. I need to send a DTI Column into array, but UniLogic help is not clear, please could you give me an example of ladder logic ?
  3. Hi everybody, I need to send a email via gmail. I can't to send a mail, this error appears: I'm using DNS: 8.8.8.8 - 8.8.4.4 I will be pending any questions, please helpme.
  4. Trying to use a wildcard in SD Delete function (Timer1.udtf.*) . I can correctly delete the specific files(Timer1.udtf.sig) , but once I add on an * for a wild card, I get an illegal filename. How can I use a wildcard in the filename ? Thanx Allan
  5. Hello, I'm considering what is the scope of the Positive Transition Event in the program. I thought it was supposed to stay on for one pass to the whole - but maybe that's not correct? In this example I'm catching the 100ms frequency and I'm checking it in a function which I call twice with different parameters - but the event only stays on in the first call to the function: and in this case the TestFunc is only: (N is the "Out" parameter) Is this as it is supposed to be? Thanks, Bjarni
  6. Hi, The compiling Ladder step (when I download a program or when I connect "Online") take between 10 to 30 min . Is that normal or there is a problem with the software?
  7. Hello Everyone, New to this software. Many thanks in advance. Question 1, So we've been able to record the data with "Data Sampling". Can someone please tell me how I can control the start and stop of data sampling? Also how may I customized the name of the sampling file, such as in MATLAB people can use the format "date is %d time is %f, DD, TT " Just so the saved data log is more readable. Question 2, How may I save a separated file content just several variables, that each time I hit a button, such as when I hit "start", save the time, date, to a txt file so I can find out when did I hit the button? Thank you very much! Yan
  8. Hi, I'm trying to build a log for my system using the Store DTI to File function. This runs after the struct containing the date is inserted into row 0 of a table, which should be appended immediately to the log file. The writes are sufficiently spaced (~30 minutes) that the SD write interval isn't an issue. I've found that when using option 2 "Only CSV" for the "Create CSV" input (F), the file is simply overwritten, and only ever contains 1 row. Option 1 "Create CSV File (All - udtf,csv,csv.zip)" does append correctly. In both cases "Append to File" (E) is set to 1 "Data will be appended to the file". This looks like a bug to me, and combined with the missing documentation for those options, I've wasted a little more time than I'd like trying to figure that out. Option 1 is an acceptable workaround, so I don't need further support, but this should be fixed. Sandy
  9. Hi, Is it possible to do safe remove of aUSB Stick/DOK from the ladder or a UI element? I'm saving a data row to SD, then the copying it to a DOK, all of which can be done from the ladder, using the status codes to avoid timing issues. I'd like to avoid the "DOK Unsafe Remove" warning that appears. I always get the same warning after using the safe remove button on a File Browser UI element, so this isn't a suitable workaround. Sandy
  10. Hello all, I am using IO remote analogue card URA0400T (16 Bit) and IFM pressure transmitter 4-20mA 0-10Bar. Attached you will find the linearisation but the output value is wrong. What am I doing wrong ?
  11. Hi there, I'm guessing that the FB that you're talking about is in Visilogic rather than Unilogic? I'm having big problems with this in unilogic. I'm trying to concatenate a bunch of strings and I just can't get anything to work reliably. Is this function synchronous or asynchronous? Any ideas why I'm having problems?
  12. What is the most efficient way to store date and time in an excel table so that it is easily view able in Excel? I converted it to a string, but the strings take up too much PLC memory. Excel can't natively interpret Unix time, so that won't work either. Is there something else Excel can interpret that I can store it as?
  13. Dear All, I am doing as follow: import a CSV file (copied from USB stick in the "data folder") with a single row of 23 Strings (each String is 25 lenght); create a UDTF file from this CSV; upload the UDTF to a DTI; read the DTI row. each of these action is done in a specific ladder rung; each rung check if the previously action was perfomed without problem...then at the end my CSV is converted; the DTI il filled with right values but when I read the DTI row I don't have any error (exist status "0") but the struct variables is not filled (all single field is empty)...I tried to write the DTI with the same struct and all works...the DTI take the new value...I forced the action (cvs->udtf->dti->read) then the DTI take the value of the CSV file but nothing change...the struct fields still have the previusly values. what can be wrong?
  14. Hello, I noticed that the Unilogic software doesn't provide counters like other software's do. I am having trouble getting out of a loop pulse timer. I am trying to get out after it loops 5 times through. Any ideas?
  15. Hi. Hope someone can help. I've got 2 analog input cards in my system. All configured the same. The one card my temp is stable but the 2nd card the reading fluctuates a lot. from 1 to 35 to 17 and so on. Connected pt100 connected to convertor to 4-20ma directly in panel to see is cable fault. Still the same. Any ideas please. Thanks.
  16. Hi Everyone I am a bit of a newb and using a US57/ -B10-TR22 PLC with the current version of unilogic The short version of my question is: when there is a power off/ on when the PLC reboots does it start the scan from the top of the ladder or does it continue from where it was when the power went off? Is there a way to make it default back to the top of the ladder? My Long explanation / issue is I have a bit that activates a compressor - even though the bit is supposed to default to 0 on startup and i have a initial cycle set bit to 0 condition if i turn the power off when the compressor is running for about one second as the PLC is intialising the compressor will come on for a second I can only assume this is the time it takes the PLC to scan from where it was on power off to the condition that resets the compressor bit... It's for an aerospace application Any help greatly appreciated Kind Regards Tyler White
  17. Hello, I have an Unistream panel and EX-RC1+ D16A3-RO16 + LC3 units hooked to it via CAN bus. I have to read position from an encoder (with A, B and Zero inputs) and wonder if someone here would give me an suggestion regarding hardware for the job? Should I just add an IO unit (and which one) or could I replace the D16A3 unit with another which also supports encoder readings? Thanks, Bjarni
  18. Hi, What is the best solution for converting two 16 bits registers from modbus device to floating point in UniStream? 2x16 bit registers = 32 int to float. (IEEE754 single pr). Is there any FB for this kind of conversion? The device information: I don´t believe I have to do this manually with calculation according to standard IEEE 754. If anybody know any method, it will be appreciated.
  19. So Im now getting my head around unistream, many thanks flex727 for the point to the examples. I have successfully got comms between uni stream and vision and have got most of my control under way and working. Took a while to get used to the new layout and working but im getting there. Question.... How do i send a set time to vision? In the vision plc there is a time entry function that communicates to other vision over modbus. I can't seem to read and write a set time both ways. uni-vis/vis-uni. Temperature settings are fine as i just use a numeric input. Just need hours and mins, is there an input for this. Many thanks, Steve
  20. 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.
  21. Why it is not possible to insert P and N contacts inside a function?
  22. I can find no information on the string function usage. This seems to be not included in the manual. I need to do string manipulation. Sifting thru all of the internet for answers is making me not happy again. Time is money. If someone out there has this information could you please post it. Thank you in advance.
  23. Hello! I am tracking some values in my application thru MQTT and would like to trigger a publish event if for example a value changes for a fixed amount or percentage. What I am using right now is periodic transfer but would like to save some bandwidth if data isn't changing much. Also, I need some kind of general solution to implement it on 50 values. Let me give you an example: we are monitoring an outside temperature. The sensor is quite unstable and changes in tenths every few seconds. It's value table at 10am might look like this: 10:00:01 102 = 10,2 degrees C 10:00:02 102 10:00:03 103 10:00:04 104 10:00:05 104 10:00:06 103 10:00:06 103 ... You get the idea. Now, I do not need to transfer these minor changes to my broker every second or on every change. I would like to detect a change of 5 tenths and only then send the data to my server. And periodically every hour for example to have records with timestamps. What are the possible solutions with UniLogic to achieve this kind of reaction with hysteresis? Regards, Ales
  24. Hello, I'm just starting my first project with UniStream/UniLogic and I have the PLC hooked to a PC via Modbus, PLC as Slave. I haven't found a way to sync the clock in PLC with the PC clock. Is there a way to set the PLC clock via the Modbus ? Thanks, Bjarni
  25. Dear, I'm trying to copy a file from a DOK to the SD; the status stay always at 1 and never change (and the file is not copied). The function is "called" by a HMI button that set a bit...in the same ladder rung this bit is reset...then is called just one time. If something in the UDFB was not set properly I should had a negative value...but this doesn't happens. What can be? thnaks
