<![CDATA[Modbus over RS485 and USB]]>Hi All,

I use the RS485 for RTU on the Monarco, separately I use the USB on the RPi for RTU, without the HAT. Can I use both at the same time? Can the Modbus driver do that?

Cheers

Mike

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
