N30 - Modbus-TCP

[GWS]

Hi,

I am trying to get the N30 to work as a modbus device that I can read from via TCP on port 502. Could not get it to work on the IP address of the N30

Hooked up a Hi-Flying EW11 TCP to modbus converter to the RS485 port in modbus mode and that does work. Can see all the registers for chips on address 100/200/300
I was assuming that the setting

TCP Server: enable
Protocol:     Modbus
local port:   502
modbus local addr 1

Would be sufficient to read the registers via the N30 IP address on port 502

Whatever I try I do get a time-out

Port 502 is open if I test with ModbusDoctor or Powershell I get connected but no readings at the expected adresses.

Also tried with setting Modbus-RTU-v2 and a virtual COM port without any responce. Please provide instructions if this should work and if so how?

Thanks,
GWS

you can read N30 by RS485 modbus protocol, not support TCP modbus by network.
