  1. To solve your problem, you need to determine if the polling speed of one meter is sufficient (that is, if you connect only one). If so, you can add three more RS485 modules to your PLC and communicate with all of them at the same time. This is how a slightly different problem was solved in this way. But this is probably the only way in your case.
  2. Hi. In my opinion, if you need almost instantaneous control of current or voltage and all frequency converters and control panel are installed in one cabinet - it is best to use analog outputs of frequency converters and analog inputs in the PLC. There is at least one analog output on the frequency converter - you can probably program the voltage or current there. If you still need to do it online - Ethernet or CANopen are standard and quick solutions. In Unitronics you can also make a hybrid decision - read information about analog inputs value (voltage on VFD analog output) using the Ethernet extension URB-TCP. P.S. We must state the fact that the Modbus through the two-wire RS485 line is quite slow and at the same time can not work at maximum speed in conditions of interference from the VFD inverter.
  3. Please read this topic If it possible - post DELTA servo nameplate.
  4. I tried to play with different options for replacing the Unitronics (Vision and Unistream) touch screen, but the available on the secondary market (not Unitronics) are only the touch screen for the V1210 (front sticker and touchscreen included). All other non-original touch screens I tested did not match the parameters used in different panels from Unitronics. At the same time, I managed to buy the display screen themselves from third-party manufacturers and use them instead of the original ones. There are also problems with a working temperature range for non original screens. Almost all non-originals do not allow work at sub-zero temperatures. Therefore, the only option for you is to order a front panel with a built-in touchscreen from the Unitronics seller. In my country, I had the opportunity to see the ordered front panel with touch screens for Unistream and successfully replaced the damaged one.
  5. Hi, do you tried to use simple USB mouse for control Unistream? I have Unistream panel with broken touch sensor. For training I use it with the connected mouse without problems for a long time.
  6. Thank you for posting a solution. If possible, say whether the panel was new (you started with open box) or used (with other project present on it).
  7. Question: Is the Unistream panel new out of the box? I encountered a problem when using a not new old version of the panel with a new CPU. The problem was a little different - but I could not overcome this problem. I replaced the panel with a new one from the box and everything started to work.
  8. From manual..... The JZ20 built-in USB port may be used for programming. Add-on Modules are available by separate order for communication and cloning. Note that the USB port and an Add-on (RS232) module cannot be physically connected at the same time Then you must check connection via info mode...
  9. I do not use this type of protocol https://www.ti.com/lit/an/sloa101b/sloa101b.pdf The main problem - find message format for this sensor type in standard hex form.
  10. Hi. Please check OS and boot version in normal PLC and PLC with issue. If it not the same - load "normal" version firmware to bad PLC. If it is the same version - please download blank project, reset and init PLC and reload project.
  11. 1 cubic meter = 1000 liters Then you must devide result by 10. Or if you only use this DW10 for HMI - shift decimal point position from 000000000m3 to 00000000.0m3
  12. Please use Example from folder C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\HSC_ HSO V120_Stepper_motor_with_Acc_and_Dec.vlp
  13. Hi, All available information about the technical characteristics and hardware configurations is available on the unitronics.com website. Information about how the software, routines, and interrupts work can be found in the Visilogic Help. At the same time, the operation of the operating system, circuitry and internal software are the intellectual property of the Unitronics company and it is probably not in open sources.
  14. Please read this topic Second tip - please instal 9.8.65 version and try to load OS firmware from this version.
  15. Please post weight device manual to topic. TX RX pin in DB9 connector pin 2 and 3 must be checked. Samba TX must go to RX pin weight device and Samba RX must be connected to weight device TX.
  16. I think - you have standard problem with TX RX wires crossed on cable. Samba standard wire is crossed for PC connection. Weight sender is crossed for PC connection. And Samba to Weight is not crossed...
  17. Probably the only exact reason for this can be determined by Unitronics support staff - support@unitronics.com. However, I can assume that the version of the software in the panel and the CPU does not match the version that is provided in Unilogic 1.32.98. It is also possible that the real-time clock is not synchronized with the environment.
  18. I don't know if anyone tried this trick ... One of my projects required significant graphic constructions on the V1210 panel. Accordingly, I first started to make the interface with the help of Visilogic and was very behind the schedule. MS Visio came to the rescue. Please see what happened. That is, the essence of the trick is to draw graphics in Visio and use it as a basis (background) for the Vision series panel. After that, I added active components to the interface. That is what I wanted to say. Creating an interface should start with planning on paper. Make a pencil sketch. If you keep an idea in mind, draw it with a simple Visilogic graphics, and then try to redo it into a new (in your opinion better) version - a headache is guaranteed. Coffee time spent creating an interface manually on paper will save you hours of sitting at your computer. And if you write variables on this sketch - the work will go even faster.
  19. Where the battery is installed in the new panel there is an insulating tape that must be pulled out. If it is a used panel, it is necessary to check and, if necessary, replace the discharged battery. I recommend reading the instructions on how to replace the battery, especially if the PLC is loaded with a program that you do not have a project file. P.S. You can also try to set RTC via UniApp panel menu for experiment.
  20. Please post used Unistream hardware. If you use only panel from modular series - you must connect PLC CPU to panel for correct RTC function. Battery for RTC present only on CPU module.
