Please download last UniLogic version from Unitronics site and test. Does it works as you need? B.R.

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.

Hi vasovas, Dis you deleted your post? Or just by mistake used Strikethrough? B.R.

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.

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.

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

Tech Support VisiLogic Download section there is PCOM protocol description.

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.

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.

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.

Does PLC you refer now connected to real system, or to kind of "simulator"?

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

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.

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.).

Rename it to .u90 abc.bak -> abc.u90
