  1. Hi,

    Please send your request to support@unitronics.com

    Add to your request PLC SN, from what version of firmware to what version of firmware you did upgrade, or what is a UniLogic version you used for firmware upgrade.

    How you did upgrade - Disk on Key, or remote.

    Does USB connection to PLC works?

  2. Hi lukeh,

    Please provide next information for successful troubleshooting:

    1. How many files are in each directory and sub-directory?

    *Review help to see limitations.

    2. What is a size of each file, especially last you are referring.

    *Very long files will make access time unacceptable.

    3. When SB344 stuck - scan and repair file structure at PC.

    4. Make visual check if a file structure is OK (no strange file names and directory names, etc.).

    If there are strange file names and directory names, etc., then backup all data and format SD card again before use.

    Show us results.

    *It is recommended to review next articles at Unitronics Helpdesk Portal:

  3. Raspberry PI serial ports are TTL (unipolar, low level).

    You cannot use it for direct connection to other non-TTL devices.

    Communication to PC use RS232 bipolar signals.

    You have to use any available TTL-to-RS232 converter, either shild, HAT, or other one.

    When hardware interface will be connected, you can continue with PI and PLC programming.

    You can read details at next link:

  4. Download Cashe by use of WiFi.

    If this is not possible - test if you can download cache in Remote Operator (PC) and look if there are errors pointing to specific picture.

    This points to bad picture image at PLC memory (and in project).

    You have to replace damaged image and reload all project, include images, and test cache load by Mobile Remote Operator.

     

  5. Hi Moran,

    Unitronics PLCs are industrial, and wotking with 0V as a '0' signal, and 24V as '1' signal.

    See details in Help.

    Unitronics PLCs does not support SPI and similar proticols, as these protocols use TTL level signals.

    If you have to support SPI protocol, you have to use converter.

  6. Hi,

    One more tricks:

    With a "Windows" key on keyboard - press and hold "Win+Shift" then press on Left/Right arrow.

    This will move active pop-up window between monitors (left, right, left, etc.).

    Hope this is a shortest .trick, which does not clean or change any program settings, or Registry.

    *Sometime you cannot close VisiLogic, and this is an invisible window keeping it open on "virtual" display.

    In this case programmers "kill" VisiLogic task and start it again.

    Now correct this by "Win+Shift" then press on Left/Right arrow.

    Hope many programmers will enjoy this "trick".

    B.R.

    Maybe best solution is to use Ehternet add-on card V200-18-ET2 and URB IO

    Please see new Visilogic 91 version.

    kratmel,

    Why you supply link to France site?

    Original documend will be found at Unitroinics Technical Library.

    It is updated from time to time.
