  1. I may add to what @DanT say - USB cable should be certified for USB 2.0. USB cables, supplied by Unitronics, are carefully tested, and tests include download of large projects, taking near 30 min or more, long test in online mode, and other tests. Other cables may have NOT SCHIELDED, BAD SCHIELD, NOT TWISTED USB wires. So if there are EMI or Ground Loop between PC/Laptop and PLC/Cabinet, you may face communication disconnects. If you are working with Laptop - check if disconnecting power supply improve communication.
  2. There is working Unitronics solution with Unitronics Router UCR-ST-B8. Jazz PLC connecting to Router's RS232 port. After additional Router configuration Jazz PLC may be used as an external MODBUS RTU device in UniCloud. Open link https://www.unitronicsplc.com/support-technical-library/ Scroll to Accessories->Routers https://www.unitronicsplc.com/wp-content/uploads/2020/06/UCR-ST-B8_INSTAL_GUIDE_DOC01004_A9_06-20-1.pdf https://www.unitronicsplc.com/wp-content/uploads/2020/07/QSG-UCR-ST-B8-EU-v1.0-web.pdf https://www.unitronicsplc.com/Documents/UniStream/Accesories/UCR/UCR_USER_GUIDE.pdf Unitronics use proprietary Firmware to support UniCloud. UniCloud link: https://unitronics.cloud/
  3. You can use one of previous versions for development😉, than convert project to last one.. You will keep number of UniLogic versions at your PC.
  4. I will suggest to close project without saving it (to not store corrupted data), Close VisiLogic. Reboot computer. Run VisiLogic installation file (unblocked!!!) and select Repair Installation. Run and test again. In my case Laptop got BSOD as result of SSD Bad Block (which being replaced during Laptop reboot), Sometime VisiLogic Uninstall than install required. Hope this helps to fix problem. In case of project error attempt to restore it from "Project->Restore".
  5. @ZebioEE As @Joe Tauser commented, number of displays will stay limited to 24. For security reasons it is recommended to use last versions of software and firmware. In this case it is better to re-design displays to have 24, not 26. This will allow to use all new versions of software and firmware with security patches. B.R.
  6. Many of new Windows 11 computers have this problem 1. Open command prompt as Administrator. 2. Add keyr: REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device" /v "ForcedPhysicalSectorSizeInBytes" /t REG_MULTI_SZ 3. Validate that key properly added: REG QUERY "HKLM\SYSTEM\CurrentControlSet\Services\stornvme\Parameters\Device" /v "ForcedPhysicalSectorSizeInBytes"
  7. It depends of PLC model and firmware version. Unitronics added FTDI and Silicon Labs support. Drivers added to use with barcode readers (check "Enable USB for HID Device"). In your case check "Enable USB for Serial Device". Test it and share results.
  8. It is recommended to send project with such problem to support@unitronics.com We will correct it and send back. B.R.
  9. It looks that you did not connected pins p-n to configure inputs as PNP or NPN. Read PLC installation manual https://unitronicsplc.com/wp-content/uploads/2015/12/JZ20-R31_JZ20-J-R31_INSTAL-GUIDE_03-141.pdf
  10. @Meeg, Send PLC serial number to support@unitronics.com to have MAC address.
  11. 1. Battery back-ups Retained Tags. 2. If SD card used - eject it and check if PLC resets or not. 3. Prepare new backup battery CR2032 and replace it. 4. You have to check battery status in Ladder by use of following bits: 5. When bit "Battery Low" is up - Customer have to replace battery in number of days to eliminate loosing retained tags. 6. Minimum battery voltage is 2.8V. 7. Battery life is dependent of number of conditions - temperature, humidity, amount of time when PLC is off (this is a time when battery is supplying power to retained memory).
  12. Hmmmm. May be you should visit Forum less?
  13. Already looks no warning How long you didn't visited forum?
  14. Please send your request to support@unitronics.com Add PLC serial number from Panel and PLC model. Support will send you instructions. *Instructions are not published, as are dependent of number of conditions (PLC model, UniLogic version, Firmware version, etc.).
  15. After converting project you have to replace all "PID" functional blocks to a new "PID Auto-tune".
