Hi George,

thank you for this question.
In general the described behaviour is possible. Connection between HMI and signal in REXYGEN is always one-by-one. You have to introduce subsystem with mask and change the mask parameter via HMI, where the connection string will be as follows:

"taskName.SubsystemName:maskParameterName"

The masked parameter can be used on as many places as desired within the specified subsystem.

For more information on defining the subsystem mask see:
https://www.rexygen.com/doc/ENGLISH/MANUALS/RexygenStudio/RexygenStudio_ENG.html#x1-340004.2

If you need additional information, let me know.

@rexpeter You are welcome Glad I could help.

Hi Phil,

let me answer your questions:

ad 1) Yes, in order to count time connect CNI=1 to "ti" input as you proposed.
ad 2) Correct, "Y" should contain time.
ad 3) Exactly.

It also assumes that your boolean signal from pushbutton is connected to input "u".

For more details about the INTE function block see docs: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/INTE.html#x81-800005

Hi Michel,

in order to make multiple HMI pages just create more *.hmi.svg files in the same folder as index.hmi.svg. No more settings is required.

You can navigate between pages using Inkspace "Link" feature. Right-click on any object (e.g. rectangle) -> Create link, right-click again -> Link Properties -> fill in the Href field with:

/hmi/*filename*.html

This object then becomes a hyperlink to another webpage.

There is also example on Multipage HMI available - have a look at "0301-07_Multi-page_HMI" example.

Hope it helps. If you encounter any difficulties, let me know.
Cheers, Tomas

Hi Phil,

for measuring time of pressed pushbutton I would go for integrator (INTE function block) with ti=1.

What is reason for measuring pushbutton pressed time? I'm asking because my proposed solution doesn't have to be the best for your end goal. Let us know.

Cheers, Tomas

Hi Peter,

thanks for interesting question. It is possible to compare two strings comparing their length and position of one substring in the other one - see attached .mdl file.

PS: function block for comparing strings is on our todo list

Hi Guenther,

thank you for your question. Yes, REXYGEN 2.50.9 was tested with Raspbian Buster without any error. Just follow our Getting Started Guide (https://www.rexygen.com/doc/ENGLISH/MANUALS/RexygenGettingStarted_RasPi/RexygenGettingStarted_RasPi_ENG.html).

If you encounter any difficulties, let me know. I will be happy to help.

Hi James,

There is no direct support in REXYGEN for reading the Raspberry Pi System Information.
However I can imagine using Python script to read out the desired information (i.e. http://cagewebdev.com/raspberry-pi-showing-some-system-info-with-a-python-script/) and write it via REST API into REXYGEN algorithm.

Have a look at example 0302-03_REST_API_Python_Bash_etc, which will help you with REXYGEN REST API integration.

Hope the above is useful for you.

Cheers,
Tomas

Hi Mike,

the watchdog for process data channel (PDC) is automated. Default timeout is 100 ms and can be set via Service channel (for more reference see: https://github.com/monarco/monarco-hat-documentation/blob/master/Monarco_HAT_SPI_Protocol.md#service-channel-register-description).

Hope it helps.

Cheers, Tomas

Hi Peter,

for "hide" or "display" any item drawn in REXYGEN HMI Designer we use Group Animation -> Opacity as you proposed. The signal mapping can be afterwards changed in the opacity component so it can be connected to any binary signal within REXYGEN project - see screenshot.

Cheers, Tomas
