If that slave is not a serial slave but a TCP modbus server on the ethernet
network, the ETIC gateway needs to know what is its IP address.
That IP address table allows to assign an IP address to each modbus
slave address.
?? To assign an IP address to each modbus slave device with which the
serial master device needs to communicate, click the “add a link”
button; Assign an IP address in front of each modbus slave address
with which the serial master device will have to communicate.
4.7.2 "Transparent" menu
The gateway provides solutions to connect serial devices to the IP network
without interpreting the application protocol. That solutions are called
transparent gateways.
4 transparent gateways are available : The raw client or server gateway,
the multicast gateway or the telnet gateway.
4.7.2.1 "Raw client" gateway
That gateway can be used if a serial master device has to send requests
to one slave device (also called server) located on the IP network.
The serial device must be for example a master device in half duplex
protocols.
