Modbus communication between freelance 800F and infi90
How to configure and communicate between master 800F modbus with infi90 modbus through TCP/IP
what is the parameter to be used , use RTU or Ascii protocol , parity ,physics ....etc.?
what the suitable converter to convert Modbus to modbus tcp/Ip?
If you cannot update your Freelance system and your infi 90 controller does not support modbus serial (RS232 or RS485) you need to use an off-the-shelf gateway that connects with serial modbus to AC 800F and with Modbus TCP to your Infi90 controller.
In that case the gateway would typically be a modbus slave on the serial bus. You would need to configure AC 800F as the Modbus master and use the modbus parameters as given by the gateway.
Maybe the community can recommend a Modbus serial to TCP gateway? Otherwise just google for Modbus TCP gateways.
