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

Hi Mike,

I know that @RexPeter use it on his setups with REXYGEN - maybe he can share some experiences with that.

Kind Regards,
Tomas

Hello Mike,

Yes, it's possible to use both RS485 for RTU on the Monarco and the USB on the RPi for RTU simultaneously. Check out the illustrative example "0121-11_Monarco_HAT_Modbus_RTU_Loopback_USB." This example features two distinct Modbus drivers: one for /dev/ttyAMA0 (Monarco HAT) and another for /dev/ttyUSB0.

Cheers,
Jan

@mikeyh You are welcome.
Cheers,
Jan

@reitinge No worries, I was just wondering. Thank you for the reply

Cheers

@reitinge Hi Jan,

Thank you. I've installed it and will try it today.

Hello,
we have released image with the REXYGEN 2.50.10-next (2.50.10.13233) which is available in our official repository.

Hi Bruno,
sorry for a late response. Could you please post here a print screen of your ARC and TRND blocks properties? I assume that you have RexArc installed on your device with command sudo apt install rexarc
and you export data from the archive to CSV using a command in RexArc (please, correct me if you are using different approach). Could you please copy this command as well?

How much difference is there in time stamps? Can't it be caused by a wrong set time zone? In the ARC block, there is a parameter ldaymax. This parameter set the maximum size of archive per day (see doc here. This could be the reason why some data is missing.

Best regards,
Jan

@mikeyh Hi Mike,

thanks for question. This is not about REXYGEN settings but Linux/Raspberry Pi OS settings.

The easiest way is to configure the RPi to have a static IP address.
Other method is to configure RPi to wait for DHCP server and if it won't receive any IP address then use fallback to static IP. This approach combines best from both static and DHCP.

Try to Google the keywords from above to get the up-to-date instructions.

Kind Regards,
Tomas
