3．Siemens S7 Ethernet to Modbus-TCP and MQTT protocols 3.1 Create a configuration acquisition channel Please open "Odot Configuration Software" and select Tool →Scan Device Click Scan device in the device Search dialog box, and click OK when finished. Lighting tests could be performed on modules; this could distinguish multiple MG-IOT03 modules in the same network. Double-click "MG-IOT03-S7" in the project bar, and the "Network Port" window and parameters of the gateway pop up on the right side. http:// www.odotautomation.com

The main parameters have the following meanings: IP address: Gateway IP, the gateway creates Modbus TCP server IP, and the user accesses this IP address and port 502 to log in Modbus TCP server. Right-click "Collection channel" in the project bar and select Add S7(Ethernet) protocol. Under the drop-down menu, appear "S7(Ethernet)_1." http:// www.odotautomation.com

Click "S7(Ethemet)_1" and the configuration channel parameters and configuration collection point window will pop up on the right. In the configuration channel parameters window, PLC IP is the IP address of the actual PLC, and the port number is fixed as 102. Click "Configure collection point" and add read or write commands in the "Add Collection Point" column.
