  1. Hello, I would ask You for information about reading data from SD card on PLC HMI. Program is done, costumer demand is to have possibility to record and read a trend (with temperature and pressure data) from every machine cycle. My V700 does it well, and costumer read data from SD on one of HMI screens. Problem is with preview of trends, because first what i see is oldest recordings and ofc (depend of number of recorded cycles), we need a lot of time to find newest trends. Is there any system solution for previewing, first from the newest trends (last recorded trend) t
  2. Hello, how to create a folder on the Unistream SD card? I need to dynamically create backup folders. I want to create one file per day. For example : / Archive / 2020/07/31 For today / Archive /2020/07/30 For yesterday Thank you in advance for your help
  3. Please support how remove warning "SD Absence" that comes after every PLC reboot. thanks
  4. Hello, I'm using Unistream 10.4. I Try to export the trend data from a Datasampler to a CSV (EXEL) File, I get it from the SD-card with filezilla. Sometimes the file will be generated and sometimes it won't I stop the data sampling and then i set the create CSV bit. in ladder function. But it not always generate the file (.ZIP) Is there an example how this file must be generated. I use Unilogic version 1.9 rev 19 I have tried a full download and so on but sometimes it works sometimes it won't Is there any example how this works. Thanks René
  5. Hi Have a problem to copy my data table on my dok. First i copy my data table on the sd with the bloc "store dti to file" and after i use the bloc copy/move to transfer the value on my dok. But the statuts stay always at -3 ( invalid dok folder path) And i use the syntax given in help. On location D i write #"DT/" Thanks for help
  6. Hi, Is there any way to load a program into a UniStream controller via a microSD card or USB memory stick? The new software looks great by the way. Is there any thought towards developing the ability for online programming edits?
  7. 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
  8. Sometimes we have problems with SD cards. At the moment we have a machine which indicates the micro SD card is locked. In the unilogic software external storage -> is SD card locked the bit is 1 After removal and inserting it into a pc, files can be deleted. So the PC doesn't see the SD lock. But why does Unitronics say so? After formatting the sd card the problem is solved. Now we have had 3 machines in the field having this problem. This is very unwanted, and needs to be resolved. What can be the reason for this?
  9. Dear Sir Any Softwere available for accessing SD Card via Ethernet cable in Unistream PLC withouting FTP Sever ??????????????????? Please suggest me ??????
  10. 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
  11. Dear Sir, I'm using UniStream PLC and I have log Data to data table and make data table Retain. i have problem it that Data table row is limited for retain Data because data table save in RAM. How make data table directly into SD Card? And any way to show Data which in SD card directly HMI Data Table?
  12. Hey, We have a 128 GB SD card that we are trying to get working with our PLC HMI panel. We want to save csv files of data to the SD card, but the PLC is not recognizing the card. We tried formatting the card using the SD Card Suite but that also didn't fix the problem. Are there any other steps we are missing to get the PLC to recognize the card? Thanks.
  13. Has anyone had success with the new "indirect, External SD, path via tag feature? This functionality is pivotal to one of my upcoming projects. I am not having any luck getting it to work with SD card installed in Unistream (\Docs\example.pdf) . If I put sample file in root directory of DOK (USB flash drive) it will open file from filename in tag no issues. I have not tried root directory on SD card. Project direct puts them in "docs" folder. Help file show syntax when file is in subfolders however I have no success. Help, please and thank you.
  14. Hello, I'm working on a program that save multiple values in a data table and at the same time in a CSV file every 200ms. Every thing is fine when I look at my data table in Unilogic, every value is saved there every 200ms but for some reason, on the CSV file, the data from row 0 to the current row is appended again every 8 seconds or so. I can add my program if anyone can look at it. Thank you
  15. Hi guys, Is it possible to update values of a data table using an USB memory stick with Unistream PLCs?
  16. Working on a project where I need to email a zipped CSV file created from Data Sampling. I can structure and send emails with no problem. I can see the CSV file via file browser, but having difficulty sending the attachment. My goal would be to allow the operator to choose from a list of csv files that updates as the files are generated from Data Sampler tests. I have tried to link a tag where you configure the email so you can type in the file name on a key pad text box. the keypad entry does not have some of the characters needed to match the file name (ie. -_ etc.). Has anyone sent C
  17. Dear all, I am using different data tables in a project, including saving and loading TDI from SD card. Some of the tables are "system" oriented like settings, and some tables are "user" oriented like programs and recipes. User should select a file by using HMI element: File selector browser . For now ALL DTI files are kept in the DT folder and selection is problematic. I need to separate each kind in a different subfolder, so the selection will be user friendly. The "Store DTI to a file" and "Store DTI to a file" ladder blocks is not giving the option for different sub dire
  18. People who see the SD Card Explorer in action usually sometimes wish to have the same functionality in their own application.Some of them contact Unitronics in order to get some details on the protocol, or ways that they can do the same, while others fear from the worst: that it's a lot of work.I know very few people that will be happy to write the whole protocol by themselves.The only guy I can think of in that matter is Ash Nielson... I have no idea where he gets his strength and energy from, but the solution for this problem is actually simpler than you think.You don't have to be energetic
