  1. HI, Please send your request to support@unitronicvs.com B.R.
  2. Hi All, A new 10.1" models required by Vesp123 already at site! Visit and review! B.R.
  3. Please download last UniLogic version from Unitronics site and test. Does it works as you need? B.R.
  4. 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.
  5. Hi vasovas, Dis you deleted your post? Or just by mistake used Strikethrough? B.R.
  6. 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.
  7. 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.
  8. 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
  9. Tech Support VisiLogic Download section there is PCOM protocol description.
  10. 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.
  11. 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.
  12. 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.
  13. Does PLC you refer now connected to real system, or to kind of "simulator"?
  14. 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
  15. 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.
  16. 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.).
  17. Hi Oleh, Why do you need timer resolution 1 msec? PLC scan time will be number of msec, and timer resolution have no meaning in this case. What PLC should do to use 1 msec timer resolution? B.R.
  18. Hi, As this problem happens after PS shortcut, you have to check power supply. 1. Check PC for output voltage, voltage fluctuation and ripple. 2. Check PC for load. Recommended to keep PS loaded not more than 80% of maximum load. *If maximum load is 2.0A, then use PC rated for 2.5A. 3. Replace PS for new/good working one. Best regards,
  19. Hi, Send your request to support@unitronics.com and explain your request. B.R.
  20. orso2p001 Is you link for Linux-like PCs? "#!/usr/bin/env python" damiankk - How about to use SQL database connection? You can create data table and add records with time stamp. Then use this information as you wish. B.R.
  21. Hi In Windows 10 use "Win"+ "Laft/Right Arrov" to move window or pop-up back to Laptop monitor. B.R.
  22. Hi, All outputs are Normal Open. Power-off PLC. If contact stay closed, then contact is welded.
  23. Please show how you set all Input jumpers and how you wired PT100 sensor. Hope it is 3 wires. Use minimum configuration for test - only 2 AI. B.R.
