The Device ID (also often called the unit ID) of the remote device must be
unique. The Device ID range is 1-255. 0 means that it is not configured.
IP address of the Modbus/TCP device. All 0s means that it is not configured.
Note: The IP address of the DeviceMaster EIP-MOD will not be accepted as
valid configuration data.
The TCP/IP port (1-65535) to connect to on the remote device.
The maximum allowable time (0 to 65535 msec) for a slave device to respond to
a message before the message is considered timed out.
If selected, a dedicated Modbus/TCP connection will be used to connect to this
remote device.
Note: This is most commonly used when connecting to another gateway,
multiple devices are being accessed, and maximum bandwidth is desired.
If selected, will forward write messages before forwarding any pending read
messages.
Note: This is most commonly used when multiple messages may be outstanding
for the remote device(s) and low latency for write messages is desired.
