    Hi Dushyant, Send your request to support@unitronics.com

    Hi Manfred, Look at "Programming tools for developers" section for document "Unitronics PCOM Protocol". Download link: https://unitronicsplc.com/Download/SoftwareUtilities/Unitronics PCOM Protocol.pdf This document explains PCOM, unitronics proprietary protocol. It explains, how to communicate to PLC. I hope this helps. B.R.

    Hi Nikola, If OS is the last, and PLC does not display text with empty project, contact your distributor for further processing. B.R.

    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.

    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.

    Hi, This is an IT problem. You have to contact your IT department to fix this. *You say, that settings resets after PC reboot.

    Hi diogki, Ausman is right about complicated net. 1.Better is to modify it as follows: 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.

    Hi, SB95 is the system bit to change the resolution of the analog input (for Jazz 2 only). It enables 12-bit analog input sampling (0-4095). Turn it ON at power-up. It is OFF by default (10-bit, 0 to 1023) If you don’t see it in the comments, please try restore System Symbols - Menu -> Restore SB default symbols.

    Hi, Look in U90Ladder Help for "Clock Functions", "Indirect Clock Functions: Open "Indirect Clock Function Example" and follow it. 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.

    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.

    Hi, Disconnect USB cable from PLC. Use "Install USB Driver" from "PC Communication Port Settings". Connect USB cable to PLC. Wait until required driver be installed. Check what COM port is linked, then use it to connect to PLC.

    Hi, To help you better, please provide more information: -Model of PLC you use. -What exactly you wish to achieve - min/max speed, distance, etc. - Stepper motor model. - Stepper motor driver model. *You cannot connect stepper motor to PLC direct. B.R.

    Hi, It will be better to review your project. Please send your project with more detailed explanation to support@unitronics.com B.R.
  14. AlexUT
    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.

    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.

    Hi ERHunt and Joe, It is not a Creator (VisiLogic creator) problem. This is Microsoft OS problem. As soon as we cannot re-create such situation, we cannot test it, etc. Please run VisiLogic installation and select "Repair". This should repair VisiLogic installation and may fix problem. Tell us if "Repair" option corrected this error or not. B.R.
  17. AlexUT
    If you did Force from VisiLogic, do Cancel Force from VisiLogic as well. The same with Info Mode Force.
  18. AlexUT
    Hi JMorel, Right-click on Set/Reset and select Cancel Force. Does this help?

    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.

    Hi vamalgise, 0-20 and 4-20 mA Analog Outputs require maximum load impedance not more than 500 oHm. If valve you use require some minimal fixed voltage to work, or have dynamic resistance, you have to use current loop repeater to fix this problem. B.R.
  22. AlexUT
    Hi Orr, It seems that you measure voltage at current output with open circuit. V200-18-E46B internal resistance for inputs AN0-AN2 (10-bit) is 500 oHm , and voltage limit is 15 V. For AN3-AN8 (12-14-bit) internal resistance is 37 oHm, and voltage limit is 1.1 V. B.R.

    Hi, Ausman, I not criticized your example. I mentioned that Interrupt Routines should be defined/created to use it. But do not required to call it from any Ladder code.. B.R.
  24. AlexUT
    Hi all, Just remark on Interrupt routines. Newer call it from Ladder. 1.25 mSec and 2.5 mSec interrupt routines are activated from OS. HSI interrupt routines activated, if HSI is configured as HSC with reload, when reload enabled, and when counter being reloaded (reached target). B.R.

    Hi kiatar, Does SB 185 active when SI 180=2? What are COM port parameters from Info mode? B.R.
