  1. Hi all, This is an open invitation for you to suggest new ideas and thoughts for Unilogic UDFB's. It is very important for us to keep track of our customers needs. As part of this agenda we want to create and develop useful tools for your benefit. These UDFB's will be attached to the next releases of Unilogic. Please feel free to suggest any idea that seems useful. Thank you
  2. Hi, I am using several 0808THS cards and on one of them I have both blocks 1 & 2 set to PWM. So output O0, O1, O4 and O5 are normal PWM outputs. O1 & O2 are working great, f = 3 kHz Duty Cycle at 50 the control is very smooth. On O4 & O5 with the same settings the motors are spasmodic in starting and stopping. (I mean too fast motor operation). Why on the first set of outputs the Duty Cycle at 50 is so smooth (slow motor speed) and on the second set the same Duty Cycle does not work out the same? Anyone faced a similar problem? thanks

  4. This has come up in the forum before - adding some of the Vision functionality to the UniStream. I'm working on a project that will be using UniStream PLCs as data concentrators / SQL gateways for many existing Vision series controllers via Modbus TCP. I will be talking to existing and yet-to-be-installed Vision controllers - probably 30 nodes on each network. The IP addresses I'm using on my test network are not the same as what will be installed, so when I take this over there I'll have to open UniLogic to manually re-enter the Modbus Slave addresses as part of the program. I (or the end user) can use Uni-Apps to change the Panel and CPU IP addresses in the field. UniStream has an IP data type. Is it possible to put an IP tag in the Modbus TCP Slave configuration table?

  5. Good morning people! I'm experiencing a problem sending emails with an UniStream USP-070-B10 programmed with UniLogic v1.28.26. When I request to send an email, the email is correctly sent, but the content of it (body), appears as an attached file. This started happening some months ago, and we don't know why, because before it was working perfectly. Does anyone know what could be going on? @Cara Bereck Levy Thanks in advance, Gonzalo!
  6. Hi, Any alternative to the vision series essential app "SD Card Explorer"? This PC application allow explore and download files stored on the SD card from remote, and I cant figure out how Unistream SD Card filed can be approached remotely. I was tinkling of sending files to FTP server, but how can I browse SD card from Unistream panel / (VNC) and select a file to send on FTP server? it seems that HMI element "Sd Browser" can only be use to transfer files to a local DOK. I believe that If it had the option of coping a selected file name to global tag (string) then it could be used with "FTP Send" function. For now the only solution I found is to use pen and paper to copy a file name from the list, and retyping file name somewhere else on the HMI, but there must be a better way... Thanks in advance to the appliers. Ofer
  7. Hi, I consider few ways to get 100 variables every second from USC-B10-TR22: 1. Create DataTable on SD card, and then get it through FTP server 2. Get data via MODBUS 3. Use any OPC client When I tested first way, there was problems with accurate timming. I forced creating line in SD file with data every 0.8s, and average time was around 0.8s, but varied between 0.6 and 1.4s Second way seems to be ok, but using Python's modbus library also occured some timming mismatch. Average was also ok, but again varied between similiar values. I'm not sure, but it also can be Python's library problem, because it is me first time with this library. So far I don't have any experience with OPC and I would like to know is it right way or not. I also tried DataSampler, but it is limited by amount of variables saved with one DataSampler, so I discontinued this way.
  8. Hey guys, I have a UniStream 7" PLC connected with EX-RC1 expansion module via CANBUS. The CANBUS is connected according to the info in the datasheet with 120 ohm resistors and everything. The complete configuration that the PLC communicates with from left to right is as follows: EX-RC1, 3 x IO_D16A3_RO16, 2 x IO_ATC8/AI8, IO_D16_A3_RO16. The PLC and the EX-RC1 is grounded and connected as it should. EX-RC1 is programmed (initialized UniCAN) and the LEDS are all working propperly (PWR ON, I/O COMM ON, BUS COMM ON). Accordingly I am able to read/write all the inputs/outputs. So, the whole system and configuration is working propperly. A few (2-3) months later EX-RC1 dies (only PWR LED is ON). I can't read/write any of the inputs/outputs and the IO modules I mentioned earlier all blink ( no communication established). I tried restarting the whole configuration by turning the power supply OFF and then ON. Tried to reprogram the EX-RC1 but when the download starts it shows an error that the device is not available (not sure what the error said). So I thought to myself what the heck. It died, it happens and I replaced the module with a brand new one and installed a separate power supply used only for the EX-RC1. The whole configuration started working again, the comm was up and the PLC software was fully functional (able to read/write and execute). However a few months later ... surprise ... EX-RC1 dies again. The exact same circumstances. Is this a compatibility issue or? Thanks in advance for your help. Any suggestions/ideas are really appreciated.
  9. Working with a new but older Unistream 10. Had to update firmware to be able to download a sample project. Successfully did one go around, apparently had to do it again according to the error message. Was using USB stick to do it. Worked fine the first time, but the second, after reboot, screen is blank and can't communicate via Ethernet or USB. Can't get into the back screen utility either. Suggestions? TIA
  10. Hi, I'm not sure about phrase in manual of URB-TCP, which says: "The adapter is limited to process 192 data bytes for inputs and 192 data bytes for outputs." Does it mean thah when I use 192 bytes as inputs, I can still use 192 bytes for outputs? Please let me understand it well, Greets, Damian
  11. Hi people, In the here and now, engineers save lives. Medicavent rose to the challenge of COVID-19—ventilators. They did it using a UniStream Built-in, model US7-B10-TA30l. As they tell it: > Our team, composed of aeronautic, mechanical and systems engineers, whose day jobs are working on classified defense contracts, have decided to rise to the occasion, working around the clock and under the radar to develop a semi-professional ventilator. The criteria selected were rapid development, production scalability, reasonable cost, meeting the strictest standards and most of all – that any one of us would feel safe using the device on a family member if, heaven forbid, they would require a ventilator.< Read the whole story here: https://medicavent.com/#story Watch the video below:
  12. Hello, I have Unistream 7 and I have problem with configuration of high-speed output of module UIS-WCB2. The high speed output 0O should be able to be configured up to 250 kHz using PWM mode. According to help, I have configured in properties windows HS Block 1 to PWM - see screenshot. Then I have configured the struct B1 according to the screenshot, but it still does not work. The classical "slow" output using function PWM worked, however I can not get to work the high-speed 100 Khz+ output mode. Thank you very much for any tips. Best regards, Martin Sirovy.
  13. Hello to all, I am working on a new system where a Unistream B5 TR22 is a Modbus TCP master to 11 Samba PLC's Nothing to exciting but my biggest problem is a lack of knowledge. This is only my second project with a unistream PLC, with the first being a very straight forward ladder program without anything special. i do have a few years of experience with visilogic so that side is not a problem. What i already figured out is how to make the set-up on the master and slave side. the thing i don't get is addressing between the devices. In visilogic i could literally select which mb,mi,ml i wanted to read or write. Now i don't see that option. how does addressing work between these devices? At the moment i am still waiting on the unistream plc to arrive, so that i can try some stuff out, butt before it arrives i would like to make a little headway before that. kind regard's Leon Mötter

  15. Dear colleagues, I'd like to share my first project using Unistream. It consists in a test bench for an important manufacturer of industrial HVAC systems and compressors in a new factory in Spain. When a new compressor is finished in the production line, it has to pass the test bench in order to be suitable for selling. These compressors can reach up to 250 KVA of power in 50 or 60 Hz and there are three independent lines: - The first line is for machines from 200 to 460 volts in 50 and 60 Hz and up to 250 KVA. - The second line is for machines from 12 to 48 volts in 50 and 60 Hz - The third line is for machines from 12 to 48 volts in DC. I used Unistream mainly for three reasons: - I needed to communicate with 5 Modbus RTU slaves (Power meters). Comms are quite easy with Unilogic. - I needed to use function blocks to control the great amount of contactors during the commutations. I can also manage them individually in manual mode with a unique faceplate indexing the data of the instance based on the object pressed in the screen. I wanted to integrate also interlock management and the fail-to-start alarms so the function block was almost mandatory. - I had a big datalogging requirement with the test results with the powers, currents, voltages, power factor from all the power meters to allow the operator to analyze the data from the test. There was requirements for trends and for exporting the data to CSV files. So the control consists in a sequence of steps which also requires intervention of the operator to select the frequency, and voltage. Once this is selected, the PLC will close the contactor with the 50 Hz or will start the speed drive with 60 Hz. It will also close the correspondent output of the transformer with the selected voltage and then it will start the fine tuning by regulating a variac up or down acting as a voltage stabilizer. I tried to do this with a PID but it’s quiet complicate since the variac is not analogic. You have to increase or decrease the voltage on it through two digital outputs (up and down). Trying to tune this PID resulted into impossible or not reaching a minimum error between the setpoint and the output or continuously oscillating. So I created my own PID where I sent a continuous pulse or small pulses depending on the distance between SP and MV. With this and a configurable minimum error I could set the MV with less than 0.5 volt error. The part with the communications was quite tricky as I couldn’t communicate with the 5 Modbus RTU slaves at the speed I needed and I had continuous congestions making the RS485 network to crash. Since the values from the power meters were used as the MV for my PID, I needed more speed so we added the TCP module to three of them. Then I had Modbus TCP and RTU but the change in the network performance was very important. The datalogging part was also challenging, because of the amount of data. I added a “record” mode on each line to start the datalogging, create a new CSV and close it once the test was completed. I’d like to thank to my colleagues in Grupo Galiana (Spain) for developing and building this amazing machine and the Unitronics forum people for the help. It was really challenging but the effort was well worthwhile. Thanks to everyone. Best Regards
  16. Hi all, Question: Is it possible to turn the backlight completely OFF in Unilogic by ladder?If I try to control the brightness by ladder; Actions - > "Change Brightness" and link a UINTThe help-file states: So this seems to be normal behavior. But if I use Uniapps -> Display & Audio; Sliding the brightness-slider to zero, does turn the display completely off!According to Version Changes, this is the case since Unilogic 1.8.51, Unistream OS 1.8.9, October 2014 Nevertheless, it would be ideal (for me and others too I think ) if we could get complete control over the backlight, from 0-100%, by ladder. In my application, the PLC will be present in a livingroom, controlling lights, heating, etc. Even at a percentage of 10%, the display is still quite lit up in a dark environment. To avoid being distracted by the lighted backlight watching tv eg.. and to save the precious backlight for prolonged life, I would like the possibility to completely turn of the backlight by ladder if the display hasn't been touched for a predefined time. => Is there a work-around without the need to open Uniapps or am I still missing something? PS. Updated the PLC and Unilogic software to latest releases, being OS 1.15.11 and V1.15.70 at the moment. Thanx in advance, Steven
  17. Hello! I have a problem with COM-ports on UniStream. After simplified configuration MODBUS on RS232 function COM-ports RS-232 modules UAC-02RS2 not activated. What is the problem?
  18. I use Com port 2 to Modbus, Com port 1 i want to use to a modem. But as son as i change Tx/Rx to Modem the Modbus communication at Com 2 stop, when change back to Tx/Rx and repower, Modbus work again. Should this work?
  19. I am working on a Unistream Project that will use an EX-RC1 module with an IO-AI4AO2. Does anybody happen to have a Visilogic example File for this configuration?

  22. Hello I am using modbus RTU Reading two sensors. Modbus ID = 1 & 2 respectively. From each sensor i read two values, one 16bit and one 32bit float. Baudrate = 9600. When I activate communication using "Active periodic" bit any one of the sensors (only) I can set my update interval at 100ms without having failures. The "funny" things occur when when i activate both: If I set my update interval at 400ms: It updates values from both sensor for a few Seconds (at 400ms rate), then it stops completely updating the reading/values from ID2. But the "success" Counter continues to count. And the values from ID1 continues to at 400ms rate. If I set my update interval at 500ms: It updates values from both sensor for a few Seconds (at 500ms rate), After a few second the ID2 values are updated at 50% rate (1s). ID1 continues to update 500ms. If I set my update interval at 1000ms: It updates values from both sensor at 1000ms without any problem. Any tips on why this happens and how to solve it? In my Application I need as fast update rates and would have thougt that beeing able to read one sensor at 100ms, I should be able to read 2 sensors at 200-250ms. Thanks for a super Product! Meeg
  23. Eurotech had previously used Unitronics Vision series all-in-one PLCs to control their extrusion equipment, but had started using a competitor’s product. However, they switched back to Unitronics products following the launch of the UniStream line; these modular, all-in-one PLCs offer a flexible, easy to use control platform. Eurotech uses UniStream line, 7, 10, and 15" models . Read all about it here: https://unitronicsplc.com/testemonials-category-carrousel/?category=miscellaneous&tid=10406

  25. Intro A UniLogic application writer need to keep on some ground rules in order to get the best performance from his UniStream. That’s because a GIF size in is calculated in the next manner: "Size in memory" = Width * Height * Frames * Bit depth Meaning that using a GIF without considering it dimensions can affected badly on the UniStream. ?How do I manage my GIFs Let's move on any of the equation elements and see how we can reduce them. Our start point is the "Damper.GIF" which dimensions are: - By right clicking on the GIF and choosing "Properties" -> "Details" Width – 1000 Height – 1000 Bit depth – 8 :By entering this link (ezgif.com) and choosing the GIF with "Choose file" and then "Upload". In the page that opened you can use - To resize the GIF Width & Height. The values that you want to resize to them are the size of the widget linked to the GIF in UniLogic.Enter the values and press "Resize it!". When it's done in the frame below you can press on "Save" to download it to your PC :(Frames – You can use the same website to remove some unneeded frames (less animated GIFs). In the next tab (1 Pressing on "skip" (2 or 3) can remove the frame (first or fifth). After any change you can use "Animate it!" and see your editing result :If we edit the example GIF to, let's say 100x100 with 5 frames (the application user can hardly tell) we save Old 1000 * 1000 * 7 * 8 = 56,000,000 bits New 100 * 100 * 5 * 8 = 400,000 bits .That's 55,600,000 bits or 6.95M bytes of memory ?To what values do I need to aim A user needs to aim as lower as possible because the memory divides between his other application features and it depends on the number of images/GIFs on the current screen. As a rule always aim to a GIF that is size is no higher than 50k
