1) I have to convert standard MODBUS TCP packets/requests to a proprietary protocol using a gateway sort of device having an IP address. The proprietary protocol devices are connected to this gateway with a serial line sub-network. Also the same gateway is required to convert the responses from the proprietary devices to MODBUS TCP.
How shall i go about that?. Any ideas?.
2) What will be the value of UNIT IDENTIFIER if more than 1 MODBUS slave ( server) is directly connected to ethernet with a network interface.
I understood from one of the documents that, it is 0xFF for all of them. Is it correct?.
3) How to configure the proprietary protocol devices in MODBUS MASTER (client) so that it can send quieries to the respective devices.
4)If 2 such gateways are there ( with one MODBUS TCP master) then - the value of UNIT IDENTIFIER shall be unique across gateways or not.
