  1. JosefSVK, You have to follow Data Sheet if you wish to have encoder working for long time. 1. You have to supply 5V to encoder. 2. You have to use TTL (from encoder) to High Level (0...+24V) converter. Such Signal Level Converters are supplied by different companies - DigiKey, Sparkfun, Element14, etc. Hope this information helps. B.R.
  2. Can you explain problem, or it is common question? 1. What you did. 2. What's going wrong. B.R.
  3. Hi, Please provide good detailed explanation of problem. Then Forum members will answer you. B.R.
  4. Hi, It is recommended to use the same VisiLogic version you used to download project. Then you can see result: If you If you use different version of VisiLogic - result may be different. B.R.
  5. John, can you clarify why first swap of modules did not fixed problem? B.R.
  6. Hi, Modem is not embedded to any PLC. 1. You need an external 3G modem to send SMS (GSM-KIT-17J-3G IG). 2. You need one of Routers (2G, 3G, 4G, LTE. Newly introduced by Unitronics) It support sending/receiving SMS by special configuration from Router and UniLogic. See "Accessories" section: https://www.unitronicsplc.com/support-technical-library/ B.R.
  7. Great suggestion, Ness, And follopwing is a link to article about how to use stored procedure: SQL Dynamic Table Name https://support.unitronics.com/index.php?/selfhelp/view-article/sql-dynamic-table-name Tell us if this solve your problem. The only thing - you have to write stored procedure and take care it is always accessible at SQL server. B.R.
  8. Hi, You have to buy modems from Unitronics to use with Unitronics PLCs. This will warrant that modem will be compatible with PLCs. Or Unitronics will clearly state what is not supported. CINTERION EHS6T USB, Firmware is 04.013 is a re-designed modem with some major changes in hardware and software. It is not sold by Unitronics and will not work with Unitronics PLCs. It is recommended to return this modem to dealer. Please review newluy introduced by Unitronicvs Router. This Router is a 2G, 3G, 4G, LTE modem-router and supporting many functions. Links:
  9. HI, Please send your request to support@unitronicvs.com B.R.
  10. Hi All, A new 10.1" models required by Vesp123 already at site! Visit and review! B.R.
  11. Please download last UniLogic version from Unitronics site and test. Does it works as you need? B.R.
  12. Hi soner54. This mean that you are THE FIRST who solved this problem! Congratulation! Can you share your experience with forum members to make this EDS file accessible for peoples who may need the same or similar requests? B.R.
  13. Hi vasovas, Dis you deleted your post? Or just by mistake used Strikethrough? B.R.
  14. Hi, The best solution to prevent PLC display "freeze" - do not play video "for a while". - Run timer to activate Screen Saver. - Make Screen Saver delay (T1). - Show display with some information about company. - Make short delay (T2). - Start play video (enable "Auto Play, disable "Repeat"). - When video playback finished - Show display with some information about company. - Repeat until display will be touched. Realizing this algorithm will eliminate display "freeze". B.R.
  15. Hi, When use mechanical switch, then it's contact(s) "bounce" when fast change it's position. Normal Digital Input has internal filter, which "neutralize" contact(s) bouncing.HSI has no such filters. You can use button on PLC display to start timer and generate fixed length output pulse. Use this pulse as input for high speed counter. Then everything should work as supposed. B.R.
  16. Hi, Please visit unitronics Helpdesk Portal and search for SD word: http://support.unitronics.com/ You can find number of articles. Review next: What brand of SD cards can UniStream PLCs support? What is the SD maximum size? Does it support SDHC? https://support.unitronics.com/index.php?/selfhelp/view-article/what-brand-of-sd-cards-can-unistream-plcs-support-what-is-the-sd-maximum-size-does-it-support-sdhc UniStream SD cards- Must I format an SD card in order to use it with UniStream? https://support.unitronics.com/index.php?/selfhelp/view-article/unistream-sd-car
  17. Tech Support VisiLogic Download section there is PCOM protocol description.
  18. Look at next link: https://www.unitronicsplc.com/Download/SoftwareUtilities/Unitronics Data Table.zip This is in "Programming tools for developers section of VisiLogic Software. B.R.
  19. If it not work with simulator, then control loop does not similar to real one, or PID startup parameters are wrong. First, you have to look for description of status=-2. 1. Clean MI 304, as it calculated by PID Autotune. 2. MI 222 should be 1000, and you can use it to indicate percentage. 3. In linearization swap 4096 and 1000. *4096 is wrong. Should be 4095 (range is 0 to 4095). MI 2000 will be in range 0 to 4095 and you should link it to Analog Output. 4. In PID Autotune select 2 cycles and run it again. Does it work now? B.R.
  20. Yes, You can create UDFB (User Defined Function Block). You can look in UniLogic examples how this works. You can download examples from following link: Visit Unitronics Helpdesk support.unitronics.com and search for "UDFB" word Here you can find information about UDFB. B.R.
  21. Does PLC you refer now connected to real system, or to kind of "simulator"?
  22. Hi kvj, Your question include two different parts. My main question is, (is doing the auto tune using PID SERVER tool will work for good ?)[1] (What will be of any possible issues later on, if any?)[2] Part [1] can be answered: PID Server is running on PC. It can consume much more resources (CPU, memory), and it may make PID Autotune more precise. But it is dependent of other conditions - PID startup parameters, Sensors/Actuators models and phisical location, inertion of sensors/actuators, etc. And good side of PID Server is possibility to save PID parameters graph. You can
  23. kvj, Please provide more details, then community will help you better. 1. Post project file. 2. Publish sensor type, output /actuator type, settings, what kind of device you manage - heater/cooler, etc. 3. Other details. B.R.
  24. Diego7793, 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.).
