yes i have seen that and that is a nice example only can you help me a bit on how to use a slider and 3 switches and how the javascript code should look like from a REXYGEN REST API.

@cechurat I wanted to add that it just works on the correct size sometimes, so I'm still glad and waiting for the fixes in the future version.

Hi Eric, you can use CANbus. See the blocks CanSend and CanRecv. There is also an example project 0406-01 included in REXYGEN Studio. For your experiments, you can use the 2-hour demo licence which covers CAN. The CANbus driver must be supported in the OS. As soon as the CAN device appears in the output of "ip link show", typically as can0, you should be fine. The baudrate is configured in /etc/rexcore/rexcore.env.d/80-candrvt.sh (uncomment the 2 lines) on your target device. Hope this helps, let me know. Jaroslav

Hi Eric, thank you for sharing your subsystem. How about turning it into a library? See Chapter 4 of REXYGEN Studio User Guide. Minor personal note: I'd use the REL block instead of the CMP block in this case. Thanks again! Best regards Jaroslav

Hi Ivan, thank you for your question. Using REXLANG function block you can manage Ethernet communication - see REXLANG documentation - part Communication functions: https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=447 Have a look also at "0504-01 Generic UDP Sender Receiver" example which can help you to start with the implementation. Regards, Tomas

@sadilekivan We always recommend to upgrade both Development Tools and REXYGEN Runtime Core. However, wait for the release of version 2.50.10 first. Thank you for understanding. Regards, Tomas

@jaroslav_sobota Hello, Selecting the HW clock seems to fix the problem, I did try this as my first solution because it was obvious to try and get the time from the Real-time circuit, but I could swear it had some issues. Must have been some other mistake I fixed along the way. Anyway, everything works as intended, thanks for the swift support with the command, it proved the time was set correctly just read from the wrong source.

Hi Ivan, thanks for question. You are right - there is more simple way to center a string than adding variable prefix and suffix. All you need is: Add a DisplayString into .svg file (Ctrl + L -> GENERAL -> Drag & Drop "DisplayString.svg") Hit F8 (or select Text Tool) Select the DisplayString and center the string: Let me know if I can be of any assistance. Regards, Tomas

Hi Martijn, here is an example project which includes a custom Javascript file: 0101-51_Custom_js.zip The main trick is to add the CUSTOM "library" in Expert settings in HMI Designer. The GENERAL library must be added as well: The "library" CUSTOM is located in the hmisrc folder and it has to have a "js" subfolder which contains your Javascript files. These are then included in the generated HMI files. Hope this helps, let me know. Best regards Jaroslav

Hi Martijn, if you mean 2 separate Raspberry Pi with Unipi 1.1 on top of each other, then yes, it is possible. It is a question of getting data from one device to the other. For this purpose you can use: RDC function block (see example 0202-12) REST API of REXYGEN (see example 0302-01) Modbus TCP connection (see example 0402-01) Hope this helps, let me know. Best regards Jaroslav

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
