Dear sirs.

I want to connect a flowmeter Nivuflow750 with modbus rtu via rs485 to rut955 and then via tcp-ip to wincc SCADA.

How can i do that?

Hello,

Depending on the wincc SCADA configuration you simply need to select rs485 mode as either MODBUS gateway or over IP as a slave device. You can find more details in the following page: https://wiki.teltonika-networks.com/view/RUT955_RS485#RS485_Configuration.

Best regards,

I did that and nothing.

I also put a 116 ohm resistor between r + and r- in rut955 and in vain.

I also tried different settings as in the attached pictures.
