  1. Dear,

     

    We are starting up our second project with UniStream and are facing for the 2nd time problems with analog Input Cards type UIA-0800N: from 8 Cards (used in the 2 Projects) 4 are giving strange results with too low measured values:

     

    Although the cards are configured in between 0 (0 mA) to 2000 (20 mA), some of them are showing surprisingly low values like 350, when receiving a 4 mA Signal (using this loop calibrator https://www.instrumart.com/products/19584/ge-druck-ups-ii-loop-calibrator). The channels affected are also not showing the correct value for 20 mA (2000), but something significantly lower like 1650.

     

    On 2 Cards this is only happening on 3 of the 8 channels, while two other cards are showing it on all channels.

     

    Since this effect is occuring also with the loop calibrator directly on the channels, and since the other cards (or channels) are working correctly, I would like to exclude cabling issues.

     

    Is there somewhere a problem with these cards in general (although: 50% trouble would be a very high ratio), does someone made a similar experience, or knows about a Workaround - like a different arrangement of the cards?

     

    I have attached screenshots of the hardware setup of the two projects.

     

    Thanks for suggestions or feedback!

  2. I have been using under Visilogic the feature to "Hide" and "Marking" screen buttons. Like this I could hide the button, if its function should not be active (not only disabled, but really "gone") - display it again, when its usage was alllowed and even use the "marked" button as feedback, if for example its initiated function was active. 1 button - 3 functions.

     

    In Unilogic I am now at the point to use binary image elements, but I am only managing to get one of the two functions implemented at once: hiding the button using two images (one blank images), but then without the marking view, while a "marked" binary image cannot be hidden anymore.

     

    Question: is there a combined "mark" and "hide" function existing in Unilogic?

     

    Thanks a lot in advance!

  3. Dear All,

     

    Does someone knows which protocol is implemented in the UniOPC package: UA (Unified Architecture) or DA (Data Access)?

     

    For one of our test installations we need to connect a V1040 PLC via OPC UA to a fuzzy logic controller that generates variable setpoints we need for our process.

     

    Thanks a lot.

  4. Hello,

    I included into the software the condition of not writing into the SD file, while the mail sending is in progress. Still: the same problems occurs: two files are attached,

    • an empty file with the name of the SD file (size on the SD card is about 450 kb)
    • the Attachment validity.txt file

    The status integer of sending the mail is 521, a number that is not explained in the help file of the VisiLogic software.

    For the hack, I have changed the value in SI58 from 10 to 1000 and the following mail left correctly, with the SD card file attached to it. I could only try it once and will send in the following days, if it solved now.

    I am a bit confused by the description of the SI58: "email file attachment size, where 1=1024 bytes ( power-up default is 1) Maximum = 10 (10 MB)"....hope that my 1000 value in SI58 is not causing a different problem

  5. Dear all,

    I have a strange problem with sending out txt files from an SD card (vision 1040, connection via ethernet to SMTP server):

    We are writing data into a txt file on an SD card that should then be send out once per week (day....) by mail. This is in principle working fine, has been tested and found to be working.

    We still get the mails, but with two attachments:

    • the txt file that should be send is empty
    • an extra txt file called "Attachment Validity.txt" is attached with the following content "1) WEEK.txt X ", where WEEK.txt is the name of the original txt file.

    The file size is less than 2 MB, SI58 is set to 10 (= 10 MB).

    Is there someone having an idea, what the reason for this problem is? I am a bit lost with this, and our client is expecting more than only empty txt files.

    So: any idea and help is very welcome!

    Olaf


  6. Dear all,

    I have a strange problem when trying to import txt files generated by a V1040. It is clearly not related to Visilogic, but maybe someone has faced and solved already the same phenomena and can help me now?

    I am generating a comma separated file (see attached CSV_FILE.jpg) with the create delimited line function. The file containes data logs of an installation that should be send by mail on a daily basis. The send file should be imported into an MS ACCESS database for all the necessary data evaluation and manipulation. (Each new data is added within access to a table with all previous data. Like this I am able to store data of years....).

    My problem is the following:

    • Importing the file in MS EXCEL is running smooth...without problem....everything correct (see EXCEL.jpg)
    • Importing the same file in MS ACCESS (see ACCESS.jgp) is making a mess out of it...adding a fleet of @@@@@ starting from row 2.

    I have no idea at all, why EXCEL is importing the file different than ACCESS....and what I can do to solve it.

    Does someone has an idea, what to do to get these @@@@@@@ out of the Access import?

    Thanks for your help!!

  7. Dear all,

    I have a major problem with two of our V1040 OPLC's: from time to time the screen "freezes". The last shown screen remains active, pushbuttons (F buttons, or on screen touchfunctions) do not have any function anymore.

    The software seems to run normal, Canbus communication is working, but the checking the Canbus network via "Communication - PC settings" is indicating two remote IO's as not reachable ?!?

    Using the Remote Operator version screen navigation and pushbuttons functions are all working (remotely...not on the screen directly).

    I am not sure, but maybe there is a link between the freeze and the use of the Remote Operator software. The PLC's are connected via Ethernet to a PC.

    The only way out is to initialise and reset the PLC...which is an quite inconvinient solution.

    When the screen is frozen I get the following status info:

    Run\Stop: Run

    Flash status: erasing

    Memory status: Idle

    Complier status: Ready

    Compiler: No Error

    After PLC init and reset, the values are changing to the following:

    Run\Stop: Run

    Flash status: Idle

    Memory status: Idle

    Complier status: Ready

    Compiler: No Error

    Any idea, what can cause the problem, and how to solve it?

    Thanks.

    Olaf

    Visilogic is : 9.3.0

    Remote Operator: 1.0.30.0


  8. Hello Simon,

    Thanks for your feedback.

    I have deleted all my displays, have only left the integers and one ASCII on the screen, have linked the refresh bit to a key, and still have the same problem.

    So I deleted also the last ASCII string, and now I have the funny effect that on one screen one integer is not shown. If I copy it to another screen, it is working, but not on the original screen: really strange ?!?!

    I have been checking with the "Display Summarize" function what may be wrong, but the feature always crashes with the message "prvShowHmiElements Automisation fault".

    Does this maybe mean something?

    Thanks!

    Olaf


  9. Hello Simon,

    Thanks for your detailed answer.

    Allow me two comments:

    1) We do have a very reasonable (!) distributor for Unitronics here, but they are also distributing lots of other products. They are capabable of solving hardware issues, but are not the correct adress for software related problems.

    2) I see the main advantage of such a forum in open discussions, open to everyone that may be in the same situation, even months later. I have already been spending hours in front of the old forum and found solutions in posts that were years old.

    Olaf

    P.S.: What is FWIW standing for?


  10. Hello,

    Not to complain, but is there a reason why upates of posts are taking so extremely long?

    I make a post when I am in sh*t, have then to wait almost 1 day before my own post is online, another day for the first answer....this is getting a bit tough, cause - tja - I am still in sh*t with my problem.

    Is there a way to make this all a bit more fluent?

    Thanks!

    Olaf
