  1. Hi Nicola,

    Please send your smallest code having this behavior to support@unitronics.com and explain step-by-step what you doing.

    This will help us to simulate this case.

    Add next information to your email:

    -JZ20 OS version (display snapshot).

    -U90Ladder version.

    -What communication interface do you use - USB, Ethernet, or RS (what is adapter model and driver version).

    -What is a PC OS (XP/7/8/10) and PC model?

    -Does this happens at this PC only, or at others PCs too.

    -Does this happens with other interfaces?

    We will answer you with results.

    B.R.

     

  2. Hi,

    This forum is dedicated for Unitronics PLCs programming.

    If your program information exchange between STM8S103F2, or STM8S105, and Unitronics PLCs, you are welcome.

    Your current topic scope i out of this forum.

    Please Google for "forum programming STM8S103F2 OR STM8S105", and you can find related forums, where forum members can help you  with your question.

    Best regards.

  3. Hi Nikola,

    Save your project.

    Create a new empty project with some text on display.

    Download this project to PLC and observe display. Does it show text?

    Set SB 9 to 1. Do you see backlight?

    If empty project show text on display, PLC works, and you have to review your project to find error.

    Look what you changed in project before having display problem.

    *You may call display at each scan.

    B.R.

  4. Hi diogki,

    Ausman is right about complicated net.

    1.Better is to modify it as follows:

    Y4pWcraDVtwAAAABJRU5ErkJggg==

    2.Snap-in allows to reset HSC, as communication to snap-in module is fast.

    Communication to expansion module is slow, this is why you cannot reset counter, located at expansion module.

    You have to use virtual counter. *MI 0 is linked to HSC in Hardware Configuration.

    I believe, that peaking is result of counter reset, which at next scan overwritten by data, received from expansion module.

    Best regards.

  5. Hi,

    Look in U90Ladder Help for  "Clock Functions", "Indirect Clock Functions:

    AF2SHvf2et0yAAAAAElFTkSuQmCC

    Open "Indirect Clock Function Example" and follow it.

    dOxy4bs4iTqz08j7nA0HfmZSAuJsrhsiZmDa0I5q

    To scroll, use key 3 (Up) and key 6 (down). To mark/unmark selected entry,  press on +/-/. key.

    When finish, press ENTER key. This return field to first value (SUN for  "Day of Week"), etc.

    You can assign key to refresh  display and scroll values for review, or you can add an additional  display with marked days of week, etc.

    "Day of Week",  for example , represented by bits in linked MI. For marked MON and TUE linked MI =6(4+2). And so one.

    I hope this will work for you.

    B.R.

     

  6. Ljuba, please post IP settings for all 3 PLCs.

    As I see, projects are very short. Publish all 3.

    *There are some settings for Jazz 2 PLCs, which is better to see in projects.

    Regarding sockets - Flex is right. When connection to both Jazz 2 is permanent, you have to use 2 sockets at V130. This is TCP/IP.

    With one socket you have to connect to first Jazz 2, send/receive data, disconnect.

    Connect to second Jazz 2, send/receive data, disconnect.

    Etc. in loop.

    Thanks for assistance,

     

    It works now. If anyone else needs it, if you use ladder comm function "V700: Read Socket Status", and compare it with 23 it's the same as SB 147-150.

     

    Just out of curiosity, do I still need CARD INIT and SOCK INIT blocks for V700 to work? I can't test it easily because I use Ethernet to communicate with it from a distance.

    Yes, you have to init Ethernet card.

    It is recommended make init for all 8 sockets to default settings. Change only what you use. See Help for details. Search for "V700" in Help.

    This helps to eliminate most of problems with sockets.

    Hey there,

    I'm trying to set up a PID loop for a fan, and when I run autotune I don't get any control value and I get a status of -13. I have the set point and upper and lower limits set.
    I can't find any reference to a -13 status anywhere, can anyone help me out?

    Thanks in advance!

    Hi all,

    Sorry for delayed reply.

    Please send your project to support@unitronics.com for review.

    Add explanation about process PID controls.

    What is a set point and what output device used (4-20 mA, 0-10V, digital output, SSR, etc.).

    What model of PLC used?

    This will help to understand why this error code appears.

     

  9. Hi,

    You should have backup of project for this PLC. Then continue.

    Power-on PLC with pressed <I> button. This will start PLC with OS stop mode.

    < PROGRAM STOP > message appears.

    Does WD error appears?

    Can you communicate to PLC with MJ20-RS adapter?

    Create empty project and download it to PLC.

    Restart PLC and check, if WD error appears or not.

    If everything is OK - check SB 8 . Is battery low?

    Download ariginal PLC project. Does it works?

    If you continue to have WD problem, contact your distributor.

    Best regards.
