Thank you Jaroslav, you learn something every day! That will help more than you know with all of my projects. especially ones with process models Cheers Mike

Hi Mike, glad I could help. A "good execution rate" always depends on the project. 20 milliseconds might be too long (controlling RPM of a motor or detecting pushbutton presses or counting pulses from a flowmeter) or way too short (temperature control). It's the responsibility of the system engineer/designer to find the appropriate timing. As for Modbus, we typically use twice the rate of the task which is using the data provided by the Modbus driver. Best regards Jaroslav

You are right, I am sorry for my mistake. According documentation https://www.rexcontrols.cz/media/2.50.5/doc/PDF/CZECH/BRef_CZ.pdf it seemed it was in basic installation. So it would be appropriate to modify my question: DO you consider embedding FMUCS to MODEL library in future? Thank you Stepan

Hi Emmanuel, thanks for the links, now I understand. You are right, for local HMI you can simply kill Chromium and reload it with a different starting page. For me, this is not appealing at all, but that's not important. You can always run a bash script from REXYGEN using the EPC function block, killing and restarting Chromium in case of an event. See example 0202-11 for inspiration. Best regards Jaroslav

Thanks Thomas I'll try these parameters. PS : later, cause a collegue take my device...

Hi Hubert, thank you for your question. It would be much more easier to answer if you can share project files which shows the example of such JSON string and function block settings. If you want to access JSON array, just use "[x]" notation, i.e. weather[0].main (means field "main" in 1st item of "weather" array) - see "0302-04 OpenWeatherMap API" example. Hope it helps. Regards, Tomas

Hello Martijn, this will save the total number of run-minutes to database everytime the RUN input drops to OFF (FALSE): See example 0404-01 and Database connection driver manual for details. Hope it helps. Jaroslav

Hello Juan, please have a look at example project 0301-07 which is included in REXYGEN Studio. It includes an application with 3 HMI screens. You simply create 3 separate .hmi.svg files in the hmisrc subfolder and create hyperlinks between them. Hope this helps, let me know. Jaroslav

Hi Emmanuel, glad you like the Monarco HAT. Monarco HAT + REXYGEN => use this forum Monarco HAT + other programming language => please use direct e-mail support Thank you. Best regards Jaroslav

Hi Emmanuel, you are right, I can replicate the problem. I'll forward this to our developers. Thanks for reporting the issue and the workaround! Best regards Jaroslav

Hi, this is possible. Put the PROJECT block into your project main file (the one with EXEC block) and tick the SourcesOnTarget parameter. Hope this helps, let me know. Jaroslav

Hi Kris, you are right, it is necessary to force the valve to fully closed position once in a while. The SRTF function block is not the best one for your needs. I'd go for the ATMT state machine or simply use an ISSW switch to send logic 1 to the DN (CLOSE) input. Jaroslav

Hi Kris, the SFCE editor should be in English by default. If this is not the case, you can switch it to English in the bottom part of the window: As for the manual, it is only in Czech at the moment: https://www.rexygen.com/doc/PDF/CZECH/SFCEditor_CZ.pdf Copy-pasting the contents into Google translate might help. In general, this tool generates the STT transition table and touts array for the ATMT or EATMT function blocks. Hope this helps at least a bit. Kind regards Jaroslav

Hi George, if I understand correctly you are trying to write (change) parameter inside function block (TIMER_:pt) from the running project, right? Have a look at function block called SETP*: https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=307 This group of blocks enables you to remotely change parameters (Real, Integer, Bool) of function blocks. If this is not answering your question, please, let me know Regards, Tomas

Hi Günther, thanks for your question. There will be available linux command line utility called RexArc in upcoming REXYGEN release version, which you can use for converting archive files to CSV/JSON files. Would that be interesting for you? Currently there is no other way how you can export the archive data. Regards, Tomas

Dear Michal, did you run Extensions->REXYGEN HMI->Update components in REXYGEN HMI Designer for your source SVG file? After that, the charts should be transparent again. If not, please share your SVG file(s) or send them via e-mail for further analysis. Kind regards Jaroslav

Dear Stepan, interesting question. When switched to flight mode, the hardware footprint (SiteID) of your laptop changes because wifi adapters disappear completely. The solution is to obtain demo licence keys for both normal and flight mode at https://licensing.rexygen.com/homepage/demo-licence and add both of them manually to C:\ProgramData\REX Controls\REX_2_50_9_10649\RexCore\licence.txt. That way you'll always have a valid licence for your laptop. Hope this helps, let me know. Best regards Jaroslav

@ryanastiefes Dear Ryan, I have used PID Control Laboratory at www.pidlab.com. Hope this helps. Best regards Jaroslav

Hi Mike, I see. In that case the simplest approach is to use the TSE block (three state element), which moreorless combines two comparators with hysteresis. Kind regards Jaroslav

Glad I could help! Best regards Jaroslav
