RS485-ETH-N can be worked as a server or client. Gateway Settings tab is divided into two sub
sections independently from Server or Client Mode.
„
MODBUS Request Side (interface in which information will be requested from RS485-ETH-N).
„

Figura 3.6: Gateway Settings
NOTE:
If the option "Validate MODBUS data" is not active, the data flow is carried out using the communication
protocol of the existing system.
When the "Validate MODBUS data" option is active, data flow is allowed if it communicates with the MODBUS
protocol during data transfer. If the protocol is not MODBUS, communication will not take place.
Default gateway settings of RS485-ETH-N are as follows:
