3.2.5. CONNECTION OF THE WIRELESS SERIAL SERVER TO FUNCTIONING IN MODBUS
GATEWAY MODE
Figure below shows the correct connection of the ADA-14110 to wireless network Wi-Fi (WLAN) to operating in
Industrial
Automation Mode
(
MODBUS Gateway
). This type of connection allows to integrate the MODBUS-TCP devices and the MODBUS-
RTU/ASCII devices in one network.
