Hi Phil,

A colleague has already responded to your query via support. To ensure we have all the information, I’m adding some additional questions here on the forum as well. We need more details from you:

Has the problem been present since the beginning, or did something change? What has changed? Did the LEDs work well before? What REXYGEN project are you using? Can you try running the "0121-09 Monarco HAT Demo Example" and see if you can trigger the LEDs? What does the system log say?

Best regards,
Jan

@Jan-Reitinger Thank you so much for efficient help. Now it works exactly as I wish.

@Jan-Reitinger Thank you so much for efficient help. So far I have used Inport and Outport blocks for working with subsystems. Now I am able to use them to exchange data between tasks.

@Tourneur

Hello,

All my apologies for this very late replying, and status of my advancement.

Unfortunately, I left completely the idea of using simulation without real target connected.

I tryed to compare the use of Rexygen with Profilab Expert, which is for me a really, and really compfortable software.
Particularly, when you are not familiary with all the complexity of programming environnement.

But yes, now, I see it's completly different, and I must re-see all my vision of Rexygen.

I finally decided to use a real target, and follow the tutorial in the documentation.

I arrived to put in place an interactive comunication with the target and my ethernet devices.

You understand lot of thing when system running, for example, i won't understood the machine interface is a web page.

Now I could, thing a little bit deeper in the working of the rexstudio.
Particularly, with Nextape, for a particular project.
I will put my question in HMI topic.

Have a good end day

@MikeyH Hi Mike,

Please, make sure to tick the "GenerateRexHMI" parameter as well.

Cheers,
Tomas

@MikeyH Hi Mike,

thanks for the report. It seems that the Archive viewer in Diagnostics is limited to the 16 signals.

I have prepared a Python script for converting the Archive timezone - find it attached.

How to use the script:

export the REXYGEN archive using the RexArc command line utility. For details execute command RexArc --help put the exported file in the same directory as the Python conversion script run the conversion script using the following command: python archive_timezone_converter.py input.csv output.csv offset

Parameters meaning:

input.csv - original file exported using RexArc output.csv - output file offset - The timezone offset to apply (in hours).

Script file: archive_timezone_converter.py

Let me know if it helps.

Cheers, Tomas

@MikeyH Hi Mike,

you are right - this is new in v3. The parameter SigNames is passed to the TRND block and can be read in Watch Mode in REXYGEN Studio (just double-click the TRND block) - see the signal annotation in the right part of a window.
It is also read by HMI component TRND which displays the information directly to the HMI (you can override the information by editing the HMI component parameters).

Cheers,
Tomas

@MikeyH Hi Mike,

I'm glad it works for you 😉

For the "variable decimal point" I would use blocks MUL and CNDR. CNDR configure so it reflects the changing of the gain according to the value.

You will probably find many other solutions which will lead you to the desired behaviour (e.g. SSW for switching gain according to the value)

Hope it helps.

Cheers,
Tomas

@MikeyH Hi Mike,

Code "-102" stands for Timeout - see Doc: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/BRef_ENGap3.html#x360-359000C

How often do you write the values?

PS: In version 3 we have introduced native support for the PostgreSQL database. Have a look at the documentation if you find it useful: https://download.rexcontrols.cz/partner/testing/rexygen/doc/3.0.0.15811/ENGLISH/MANUALS/PqDrv/PqDrv_ENG.html

Cheers,
Tomas

@mtomek Hi Michal,

if the period of read/write request won't be shorter than a few seconds I would use REXYGEN REST API - see docs: https://www.rexygen.com/doc/ENGLISH/MANUALS/RexRestApi/RexRestApi_ENG.html

Have a look at the "0302 IoT Integrations" examples folder - it contains some examples on using REST API.

Cheers,
Tomas

@cechurat Hi Thomas,

Thanks for the replay.

I'm about to get some pi 5's to run REXYGEN on, so that's good to know. I won't be fitting Monarco HATs to these so no issue there.

But will be getting one once you release the updated design etc

Cheers,
Mike

@martinpies Hello Martin,

Thank you for your feedback. I'm sorry to hear that you are struggling with using REXYGEN Studio. In version 2.50.12 there is a known issue with the closing of diagnostic protocol. The recommended workflow is disconnecting completely from the target (F8) before Compile and Download (F6). In other words - avoid reconnecting to the running target when developing the project.

Please, let me know your findings.

Cheers,
Tomas

@stepan-ozana Hello, yes PWM flags should work as HW PWM on GPIO12, GPIO13, GPIO18, GPIO19 pins. The functionality should be the same as described here: https://www.raspberrypi.com/documentation/computers/raspberry-pi.html

Best regards,

@jarek If the UniPi you are using have RS485 bus it will work.

Hi Istrate,

it seems that the issue is remote access to the Database which is forbidden by default. Have a look at this tutorial: https://webdock.io/en/docs/how-guides/database-guides/remote-access-your-mariadb-mysql-database-ubuntu-focal-mariadb-v106

Kind regards,
Tomas

Hi Mateo,

Thank you for your question. The error you are referring to is not related to the Database connection - it's about the connection between Studio and the target device.

I recommend you start with simple examples 0404-01 MySQL Simple Export and 0404-02 MySQL Simple Import.

The most tricky part is remote access to the Database which is forbidden by default. Have a look at this tutorial: https://webdock.io/en/docs/how-guides/database-guides/remote-access-your-mariadb-mysql-database-ubuntu-focal-mariadb-v106

First, you can try to run the Database on the same target as the REXYGEN is running. Send data locally from REXYGEN to MySQL DB should be done without any issues.

Let me know if it helped.

Cheers, Tomas
