via cellular network. Can we send this data to server as a client (in other words: if something comes from RS485 - convert it to Modbus TCP and send to specified ip address/port)? And if it is possible - what shall we configure on RTU955 (I find nothing about this in manual).

Hello,

Yes, this is possible. Simply navigate to "Services -> RS232/RS485 -> RS485" menu and configure the service:

  • Use "Serial type: Over IP" and "Mode: Client"
  • You can leave "Reconnect interval (s)" value empty or enter e.g. "5" seconds for more aggressive connection

Hi,

Router has Modbus gateway Serial type which allows redirecting TCP data coming to a specified port to RTU specified by the Slave ID. The Slave ID can be specified by the user or be obtained directly from the Modbus header.

Basically request to your device (connected to router RS485) should arrive from server.

Does this also translate the Modbus-RTU data to Modbus-TCP? As I know Modbus-TCP has no checksum in data. So if it's only a transparent connection it will not work with an Modbus-TCP client.
