@martijnperdaan said in Database: Schakelaars the input SwitchOn is variable sometimes it is Switch1On and sometimes Switch2On and sometimes Switch3On so he has to read the value of for example Switch1On from the tablet Switches for example, he should get back 01101010 as answer because it is stored underneath but he returns Switch1On in response the system does not log an error because the SQL command line must be normal

Hi Martijn, this functionality is often called Radio button. This feature is not supported in REXYGEN now. As a workaround you can use ComboBox component which does the same with only different representation. Regards Tomas

Hi Martijn, thank you for your question. In current REXYGEN version (2.50.9) there is no such feature as popup window. However it can be done by using "hide_by" parameter in HMI component. The background rectangle can be drawn in REXYGEN HMI Designer and animated using "Group Animation - Opacity" (Ctrl + J). Regards Tomas

I solved it with a REXLANG block

@enovikoff Thank you, I'll see what can be done in this direction. Jaroslav

Hello, thanks for sharing your experience and findings. There's nothing to add, only that from the nearest release the REXYGEN compiler will issue a warning when two drivers use the same configuration .rio file. Jaroslav

Hello, thanks for another contribution! Why not use the MP block for starting the calibration procedure? Minor note: We always recommend keeping the block name for clarity and "readability" of the algorithm. I'd go for "REXLANG_MHZ16" in this case. Thanks again, Jaroslav

Can you give me an example how to do that with that function block I can't figure it out myself?

Hello, I do not have any better advice than to add this line to your code, which will make the compiler believe that the variable dateInterval is used. dateInterval = dateInterval; Can you share or send your code leading to such a false warning? Thank you. Jaroslav

Hi Eric, thank you for sharing your work! Jaroslav

Hi, how about running Python code alongside REXYGEN and pushing the data to running task(s) via REST API of REXYGEN? This is shown in example project 0302-03 which is included in REXYGEN Studio. Both RS-232 and CAN bus are also an option, but in that case you'll only get raw data and you'll have to parse it yourself to get useful information. Hope this helps, let me know. Jaroslav

@RexPeter said in Automatic keeping track of project revision: Software is in my point of view never "finished" Tell us about it Your recommendation regarding revision identifier is in our pipeline. Since Monday already. Thanks! Jaroslav

Please start a new topic for questions not directly related to the original question. There is no such block, you must combine the existing blocks to achieve this. Jaroslav

See example 0122-12: Best regards Jaroslav

Hello Martijn, here is an example with one CNR and 2 CNB constants which are controlled from web HMI via REST API: 0301-21_REST_API_Webpage_Javascript.zip I believe that's all you need. Now it's on you to build upon this concept. Btw, what is your motivation for building your very own HMI? From your questions I guess that using the HMI Designer and building the HMI without any hand coding would be much easier and more straightforward for you. Let me know. Jaroslav

@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.
