Modbus RTU

Jenny

Hi,

Have MangoES supported Modbus RTU ?
If this, how can I enable it.

Make a Modbus serial data source
select Modbus RTU in the dropdown
use the device '/dev/ttyUSB0' as the port and
connect your Modbus RTU device to the RS-485 port on the MangoES.

Jeremyh,
Thank you for kindly reply.
And my device is Modbus RTU over TCP/IP.

Any suggestion?

Mango has two modbus data sources. Modbus RTU and Modbus IP. Just use the one that is appropriate for your connection type. RTU is for serial ports and IP is for Ethernet based devices.

What is your device?

"Modbus TCP" and "Modbus RTU over TCP" are actually two different things.
