3.2.4. CONVERTERS CONNECTION AS MODBUS GATEWAY
Figure 8 shows correct connection of ADA-13040MG to ETHERNET network Wi-Fi (LAN) to functioning in
Industrial Automation
Mode (MODBUS Gateway)
. This type of connection allows to integrate MODBUS-TCP devices and MODBUS-RTU/ASCII devices in
one network.
