  1. How can I scroll through the Ladder UI (left and right) ? When I'm working on a small window (not full screen), I can only scroll up and down.
  2. Long compiling Ladder time

    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?
  3. Hi, I have a project (HMI USP-070-B10) with several users and groups. Using 3 access levels into the screen controls. I have a client who would like to have full access without login every time when power on the HMI. Is it possible to make something like auto login or to make default user with full access? Thank you in advance, Ognyan Obretenov
  4. Hi, I'm using UniStream with UniLogic (19.2). I'm unsure on how to use the "SQL Query" function block. the "SQL Query" has 3 fields: Query - Input, SQL query to execute. Parameters - Input, query parameter Outputs - Output , query output When I write the next query: Insert into Agua (Tiempo) Values (T_Agua) How does the PLC knows the direction of the database? What do I put in the Parameters and Outputs fields? Is there any file or webinar that I can check regarding this topic?
  5. I've tried to find a way to load a HMI screen via ladder within UniStream (which I found to be a very useful function within VisiLogic), but so far without success. Is there a way to get things done like: if a condition turns on screen n° xxx will be opened? Thanks for your feedback. Olaf
  6. Hi, What I want to do set and on and off time and date (which are on different dates) but can only get it to work with the time, not the date. I can get it to work using the "From Hour" and "To Hour" tags but I cant get it to work with the "Month" or "Day of the "Month" tags. I'm not sure of the format, I have been trying to write to them from a RTC Date variable using the array functions and a Date input from the HMI which seems to be working but the "Schedule" function doesn't seem to use the information. I have "2017" written to the "From Year" and "To Year". Any help would be great. Adam
  7. Is there any way to remove "Add new subroutine" button? I often click on it when I want to add a new net.
  8. Hi all! I would like to place a local timer in a UDFB, but this option is not available (The timer save key is disable when it is set to local) I guess there is a reason why local timer is not possible... The option I know is to define the timer as a Function-In , but then i have to connect a different global timer on each of the UDFB instances, and in case there are many of them we miss the concept of UDFB somehow. So I was trying another option to count seconds on a Local Counter (Inc function to Local INT16 Tag) . The counter pulse come from a Function-In Bit (One scan every 1 second). The problem with is the counter is not increasing if the tag is local, and it dose very well if the tag is global. This I can see with the latest Unilogic version that support monitoring UDFB online, very helpful! Any help regarding timing and counting within UDFB local tags is welcome. Ofer
  9. Is it possible on initiate a screenshot through ladder logic or is only possible through UniApps?
  10. Dear Community, Is it possible to have a bit trigger a message box? I have some ladder logic that determines if high and low user definable setpoints are equal to each other or inverse to each other. undesirable setpoint conditions make bit named SP> and SP= go true. Right now I have and indexed HMI text element that shows: legal entries, sp = illegal, sp> illegal, both illegal. I don't really want to trigger an alarm (though i could). The message box would be a nice way to signal operator of an illegal entry. I can't use legal entry ranges on numeric elements because legality is conditional to other setpoints. Thanks -dB
  11. How to convert a number to string ?
  12. Dear, Since a few weeks I started working with the Vision PLC 430 J T 2. I have three expansion modules (2 for analog inputs and 1 for load cells). Recently I've started writing down the logic of my final program. Until now I only have experience with the Siemens S7 with associated software. I want to create a sequence where the transition from state to state is based upon conditions. Only one transition can be true at any point and the sequence is always the same. I've always done this with flip flops which set and reset each other. Now I’m searching for the correct way to implement this into the Vision software. Can someone advise me on this? Thank you in advance! Nick Verlooy
  13. "Store" Ladder function does not work

    Hi, I want to store the int16 value of an analog input into a global tag int16. The value of the input is correct but the Store Integer function does not work. The value of the global tag remains 0. I tried to find info on the subject without success. Can anyone help me? This is the view in online mode...
  14. 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
  15. Hello, could you help me please, I have function fill array part, I can not to find in help how can use it. In help are no information about array function. Old VisiLogic was more simple in this, Thank for help
  16. Dear Community, I couldn't find anything in the UniLogic help files about array functions. Is it just me or is the help section grossly incomplete in UniLogic ?! Visilogic seems to be very comprehensive in help topics with examples for every FB in the software. Feel some uncertainty without help topics on select functions, especially with the differences in terminology from Visilogic. Example being: a vector copy of 30 MI's in Visilogic is equivocal to "copy array part to array"?? Failed to find help topic with example. I tried to build a UDFB last night to function like Visilogic's vector linearization function and gave up. Just stacked individual linearization functions instead. I get the feeling the authors of UniLogic were not the same people who composed Visilogic. Old dog learning new tricks, I'll get there.
  17. Hi! I would like to know if in the future (in the short term) you can activate Message Box from ladder?
  18. Tag Name to String

    Hi All - I made a complex function that has used all 10 inputs, so I can't just add another input for this, I just need the name of the tag in the function (call it CBA bit or whatever it is called) that triggers a bad condition, and I need to post that tag name to a string (in a data table struct). I am just looking for the easiest way to get that info into the data table from inside the function without a string input so that I don't have to do it 240 times elsewhere, and I figure getting the tag name( which I know already) into a string would work best, if I can do it. I am using a bunch of UID-0016R's and they have addresses with Alias Names which seem to be strings too but this is in the function output. Any ideas how or any other options? Also, is it possible to see inside a function while in Online mode for troubleshooting - all I seem to be able to see is the inputs and outputs? Thanks!
  19. Toggle bit in vector

    What is the equivalent function in Unilogic to Visilogic's toggle bit in vector function block? Same question on vector fill? Unilogic equivalent?
  20. Hello, can you give me advice how can I find out which language is on at the moment through the ladder? I need to open pdf files according to current language. I can't find system variables, which says this information.
  21. HEX to ASCII

    I have 6 consecutive INT16 type tags that contain 2 characters each of ASCII characters in HEX format. I would like to convert/concactenate them all to a single ASCII type tag. Is there a simple way to do this? I couldn't find any conversion instructions and the sample project I looked at (UniStream_070_Num_To_ASCII) seems to be an incredible amount of code to do a simple conversion.
  22. Dear All, after I have "studying" your example about the alarms management I have created my function with "alarms actual" and "alarms history"; at the beginning I created a loop to check if an alarm is present in "actual" and reset the row after transfered it to "history"...it worked. In the next step I added a BIT check (image 1) to verify if the alarm was reseted by the device that I have to controll with the PLC...and if it still present do as set (reset row and transfer) and add a "note" in other DTI...if it was already reset do only what was set (reset row and transfer). after this modification the loop doesn't work anymore...works only for the first row detected with an alarm...I checked and I found that the BIT highlighted in GREEN, in the immage 2, is set in rung 1 but is not reset in rung 2 (at the end of the row). I done a lot of test and modifications...at the end I had to insert a reset and a timer ON of 15 ms (image 3a) to do the reset action of it...in this way it works....only reset without the timer doesn't work. In this case the BITs that I used are "global" and are used only in this function; are present only in two rungs (set, contact, reset) Some suggestions? thanks
  23. I have to retrieve and import a CSV file to a DTI. There is no problem about the FTP section, but when I try to convert a CSV file to an UDTF file I have got an error if the CSV file has more than 127 lines. Is there a way to resolve this issue ? My final CSV file to import will maybe have near of 500 lines. Thanks for reading
  24. I want to trigger an action in a specific time of the day, that i would define. For that I want to use the schedule function. Can you explain how to use this function, because there is no info in the help files.
  25. Hi all, What is the meaning of "pen icon" appearing in ladder and HMI sections in solution explorer? Because, I save the project - all pen icons disappears, quit Unilogic, start Unilogic, open the same project, and the again I have these "pen icons". Similar issue is: in the same project I have HMI with data table visualisation. In the properties window I have chosen the right table and tag for "Tag:Selected Row". I save the project, guit Unilogic, start Unilogic, open the same project, and "Tag:Selected Row" is empty. Any ideas for this strange behavior, and aren't the two issues connected? Regards
