Hi Emmanuel,

thanks for your question. Can you share configuration of Modbus in your project (or preferably whole REXYGEN project if possible) so I can have a look at the settings you used?

There is possibility to Swap Bytes or Swap Words at each Modbus item - did you try that?

Regards, Tomas

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

Hi Emmanuel,

there isn't way how to change URL (switch to different page) in case of Alarm.

However you can use "hide_by" datapoint which is part of every HMI component. When the "hide_by" datapoint is ON the specified component won't be visible and vice versa:

It is beneficial to combine this feature with making your component out of standard Inkscape shapes - rectangles, circles, etc. (Extensions -> REXYGEN HMI -> Group Animaton (CTRL + J)).

Note: I recommend to use Layers in REXYGEN HMI Designer - just to keep the overlapping components "readable" and "editable" - https://wiki.inkscape.org/wiki/index.php/Layer_Dialog

There is also "0301-08 HMI Animation DEMO" example available which demonstrates all kinds of Group Animations.

Let me know if I can be of assistance.

PS: manual switching between multiple HMI pages is also possible - see another topic: https://forum.rexygen.com/topic/57/hmi-with-multiple-pages

Hi Kris,

thanks for interesting question.

The behaviour with persistent "y0" parameter can be achieved as follows:

• make MVD parameters persistent:
  

• ensure that y0 will get updated everytime the MVD:y value is changed by adding SETPR function block - see details in following screenshot:
  

Note:
For devices without battery-backed RAM memory (e.g. Raspberry Pi) this approach will produce periodic writes to SD card. The period can be set using RexCore configuration file.

Let me know if it solved your request.

Cheers, Tomas

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

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.

Hi,

it is definitely possible to have the MQTT server on the same Raspberry with REXYGEN. It depends on the expected data load. Just have a look at Raspberry performance and CPU loads.

Hi Geocipo,

thanks for asking. You can send HTTP commands (HTTP GET and HTTP POST) using HTTP2 function block. Have a look at "0302 IoT Integrations" example folder where you can find many examples with HTTP2 function block in various situations.

If you need more information, let me know.

Tomas

Hi Mike,

unfortunately the REXYGEN runtime won't run on an ESP32, however you can integrate it with other REXYGEN enabled device using REST API and exchange data. Have a look at example "0302-11 ESP8266 REST API", which is originally meant for ESP8266 - I believe that the code will work also for ESP32 (with minor tweaks - don't have any ESP32 on my desk available for testing).

Let us know about your progress.

Regards, Tomas

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.
