(Modbus TCP)
Port Number Which port to use for Modbus TCP communication. Default: 502
Gateway Registers The address offset to the gateway internal registers (if enabled). See page 2-7 "Internal Regis-
ters" for details.
Server Idle Time out Idle time out in seconds for the Modbus/TCP connection. If the gateway doesn't receive any
Modbus/TCP query within this time the connection sill be closed. Default: 60 s.
IP Authentication Defines the IP-number of the device that is allowed to connect to the gateway.
Note: To ensure that the Modbus master can communicate with all slaves present on the bus, do not
assign the same address to more than one Modbus device.

RTU or ASCII
Default value 200ms
EIA-485 or EIA-232
300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 or 115200 bps
Select number of stop bits and if parity should be enabled (odd or even)
Some nodes on the network may need extra time to finish handling one mes-
sage before they can receive the next message.
Specifies the time (in ms) that separates two messages. If set to 0 (zero), the
gateway will use the standard Modbus delimiter of 3.5 characters (the actual
number of ms will be calculated automatically based on the currently used
communication settings).
