  1. I would suggest to contact Support. I had an issue once with a new UniStream that gave me "Invalid MAC Address" msg on power-up.  Same thing with the CPU being in stop mode. Tech support had to do a remote connection through my laptop to fix the issue. It was quite involved and not something that could have been solved simply by providing instructions to follow.

  2. Possible Cause 1:  the CPU might be in STOP mode, not RUN. You can check/change the status using UniApps | System | Control.

                                              you can also use Unilogic to change the run/stop status of the PLC using "PLC Control", under "Unistream Management" on the PLC tab of the ribbon.

    Possible Cause 2: you may have your ladder logic in a function, other than the Main function, that is not being called. If this is the case, you will get a warning when you compile/download your project.

     

  3. OK. thanks.

    This brings up a new topic now...Combo Box list of text source

    I was hoping I could utilize the "Lists" with combo boxes somehow...I would like to have the "Options: List" collection of a combo box be sourced from a dynamic list, or data table column of strings. 

    Currently, the list for the combo box is fixed and can't be changed thru program code or operator entry. 

    I wonder if it's possible to somehow link a data table column of strings, or a list of strings to a Combo Box or "List of Text Variable"

  4. Can someone help me out to understand how to use the Lists feature found in the solution explorer. I don't see anything in the help files. I can see that there are many types of Lists available, and I can easily create Lists, but I don't see where/how to actually use or reference the List(s), once created.

  5. I have had this issue right from the start with UniLogic...on multiple PC's and laptops. Even with VisiLogic, but there I can check the "transparent background" check box to easily eliminate it.

    In UniLogic, I set the background fill to transparent and it does nothing. I was just putting up with it  up until now, but it would be nice to get to the bottom of it. 

    As for image programs, I think all I have is what ever comes standard with Windows, but I'll double check that this weekend. Currently, I am running Windows 10

  6. "Btw, can you download the following image?"

     

    I downloaded the image and it did indeed have a transparent background. Unipics from the folder, "Unitronics \ Unitronics Visilogic_C\ Data \ ImagesC \ UniPics \ Large \ Switches \ Indexed Large" all still display a white background. :( 

    I tried the "onlinepngtools" app, and it worked to make the background transparent, but now I have the diagonal lines across the image. Also, I had to save it to a word doc first, then "save as picture" in order to be able to use it with UniLogic.

  7. Hi Saragani.

    So far, all of the unipics that I have used display the white background...but I have mostly only used the lamps. I will check some others though, just to see. The few .png images that I have downloaded from the web are the same, but usually darker background.

    Pascal, thanks for the link. That looks like a very useful tool. I will try it out 

  8. Does anyone know of a way to make the background of UniPic images  invisible? For example, I have used the "UniPics-Lights & Lamps-074.png" image. It is a green circle but has a white square background. If I use it on a screen with a white background, the square is not visible, but if I use it on any other colour background, the white square is visible. I could save them as a bitmap and edit the background out, but that is a lot of work to do for every image. I saw another image, almost identical, in a sample PID program, "UniPics-Leds-Green-04-On.Png" . This image has a transparent square background, but I can't find the source for this image, and I don't see any property that I can set the background to transparent.

     

  9. Now that you have EtherCAT capabilities, it would be great to add safety controllers and I/O to the Unistream line up. Safety over EtherCAT ( fsoe )

    Also, with the servo drive line-up, it would be great to have "Safe Torque OFF" ( STO ) inputs built in. I think you have them on the VFD's already.

    Looking forward to new releases, whatever they may be.

  10. I had a client's USP-070-B10 / USC-P-B10 that was stuck "spinning" during boot-up. After some swapping of HMI, then CPU, I discovered that the SD card was corrupted. There was a folder created, named "System", and this folder was filled with 8GB (full capacity of the card) of "jibberish". Tech support told me that the system folder is only  created/used when the CPU reports a major event.  I, nor the client know of any event that might fit that description. I re-formatted the SD card, and everything worked fine, and has been for a few weeks now....and no "system" folder exists on the card.

    Just thought I would throw this out there in case anybody else comes up against the same problem.

  11. Hi.

    I want to use an M91 to dynamically linearize two analog inputs, perform some math on the results and then use those results to linearize one analog output.

    I have seen the sample ladder code, using SI 80 thru SI84, and the trigger bit SB80. 

    I don't have an M91 handy to test this so my question is...

    If I set all the values into SI80-SI84, then set bit SB80, then store the SI85 value to an MI, immediately after setting the SB80 bit, will it actually store the linearized value, or does the program need to complete another scan after setting the SB80 bit, before performing the linearization?

     

  12. Hi Akash.

    I used an SR-1000 with a Unistream 15.6. I have attached the exported ladder function, related to the bar code(in my case, QR code) reader. I used Ethernet IP to communicate and have also attached a screen shot of the Ethernet IP settings used.

    It was 6 years ago and I was just learning Unilogic, so I am guessing there may be an easier solution, but this one has been running perfectly since installation.

    I can't send you the entire program for proprietary reasons.  The logic is a bit involved, but I have commented extensively, so you should be able to sort things out with what I can provide.

    The Unistream was programmed with Unilogic version 1.26.90.0

    I have also attached a configuration file for the scanner. You will need the Keyence software (Auto ID Network Navigator v6.5, is what I used)

    Hope this helps.

  13. I create a duplicate of my start screen, but with a full screen "invisible" button with a "Last Screen" action. Then I use the system tag "General.Touched Bit" with a timer to trigger a project level action that loads my duplicate start screen ( "screen saver" ) and reduces the screen brightness, after 5 minutes with no touch screen activity. 

    About the brightness...the change from 100% to 10% is barely noticeable. I wish it could be even dimmer

  14. You do not need the Scanner Node1 for the URB. If your URB has the same IP address as that scanner node, that may be causing a problem. Get rid of the scanner node 1 in the configuration and then monitor the I/O. In your photo, the Unilogic is not online, so I can't see if the input is on or not.

  15. Disregard my previous question...I found that the User Access Control in the PLC was not being overwritten when I did a Full Download, or Full Download w/Upload and selected the "Download" button. I had to select the "Download/Reset" option (even though the differences dialog box showed that a reset wasn't required), in order to get the "overwrite user access control?" check box option. After I did that, everything checks out just fine.
