Hi Bruno,
the Monarco HAT has hardware PWM and therefore does not need to create PWM in software using a PWM block. Documentation to the PWM on Monarco HAT can be found on page 16 in Monarco technical specification https://www.monarco.io/docs/Monarco-HAT-Hardware-Reference-Manual.pdf.
All you need to do is set the PWM frequency (in your case to 50 Hz) and calculate the actual duty cycle for one channel according to the equation:

Duty_cycle = pulse_width/period_length

Take a look at example 0121-05_Monarco_HAT_PWM_output to find out how to set the frequency and duty cycle for PWM1 (for example).

Hope, this will be helpfull.
Cheers
Jan.

Hi Pedro, as far as I know, IEC 61850 in Rexygen is not supported in any way. If there is some Python library, it would be possible to use a Python block (documentation here: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/PYTHON.html#x276-27500016).

Cheers,
Jan

@relaxc Hello,

• C code has certain limitations in the REXLANG block. A detailed description of the block is available here: https://www.rexygen.com/doc/ENGLISH/MANUALS/BRef/REXLANG.html#x274-27300015.
• Examples for using the REXLANG block are available in the installation. By default on the C:\Program Files\REX Controls\REXYGEN 2.50.10.13491\Examples\0203_Function_Blocks_REXLANG path.
• Compilation takes place only when translating the whole project in Rexygen Studio.
• Unfortunately, .so or .dll files are not supported in REXLANG .
• In REXYGEN, it is possible to call standard C language scripts with linked .so or .dll files. Scripts can be executed using the EPC block (documentation here).
• If you can use Python instead of C, take a look at the Python block (documentation here).

Cheers,
Jan

@mtomek Hi Michal,
according to REXduino_slave.ino, the errors mean:

49 52 - Error command - wrong pin number
51 49 - Serial bus buffer is full
49 50 - Error command - unknown command

Unfortunately, I can't say remotely what happened. Have this errors been repeated? Has there been an error 52 51 since the last time?

Cheers,
Jan

@pedrowirya Dear Pedro,
thank you for information. I'm glad, everything is working now.

Best regards,
Jan

@pedrowirya Dear Pedro,
please download the latest version of REXduino block library from git repository. You need to upload a new version of REXduino_slave.ino to your Arduino. Next, please copy the new version of the Arduino_UNO block into your REXYGEN project. The error should disappear. Also look at this thread, where a similar problem was solved.

Cheers,
Jan

@mikeyh Dear Mike,
we have published new REXYGEN pre-release version 2.50-next (2.50.10-13491) which is now available for testing. This version contains fix for the archive bug.

If you want to update your older REXYGEN-next version, just update and upgrade with

sudo apt update
sudo apt upgrade rexygen-runtime

Best regards,
Jan

@mikeyh Hi Mike,
I'm sorry, I tested deleting archives on our working version of REXYGEN, where this problem has already been fixed. I have now spoken to the main developer, who should publish a new version of REXYGEN-next in a few days.

I'll let you know when the new -next version is released. There, the problem with writing to the deleted archive will be solved.

Cheers,
Jan

@mikeyh Hi Mike,
yes the version v0.5.0-543 is the last official version. So it's weird that it didn't work for you and it did for me. I'll try to find out the cause. Anyway, it's good that you solved it.

To restart after deleting the archive: Could you please post the ARC block settings here?

Cheers,
Jan

@mikeyh Hi Mike,
what is your DWM version? You can find it by clicking on the menu icon in the upper right corner (see image below).

I have tested RTC changing in versions v0.5.0-543 and v0.5.0-552 and it works for me.

Please, try to update your DWM using Terminal:

sudo apt update
sudo apt upgrade rex-dwm

Deleting an archive from the File browser can be set, but it is not completely straightforward. It is easier to do it manually from terminal or create an event_log class in DWM with the allowDeleting option. Please take a look at Chapter 4 in DWM.

Add following code part into /rex/dwm/config.js. Attention: For security reasons, this file cannot be edited directly using REXYGEN DWM.

    {
      class: 'event_log',
      archive: 'ARC',
      allowDeleting: true
    },

After refreshing the DWM page, there should be new tab called Event log with Delete archive icon (see figure below).

Cheers,
Jan

Hi Michal, we've been thinking about your problem and come to the conclusion that the 1-Wire bus may still be overloaded. After all, you have a lot of those temperature sensors there. Please try to increase the task period from 1 s to 1.5 s or disconnect a few sensors. If both errors and peaks disappear, there is a problem with 1-Wire.

Best regards,
Jan
