Log on to the Gateway and go to the Device discovery page. Click Discovering a Modbus device?
To discover Modbus devices manually, enter the Device type, Device vendor, Device family, and Slave ID. For TCP, specify the IP address and Port (502 is default). For Serial (RTU), enter the Port, Baud rate, Data bits, Parity, Stop bits, and Flow control.
Importing a device list
You can import a device list that contains the IP addresses and slave IDs for multiple Modbus TCP devices of the same type, vendor, and family. Each line must have both the IP address and slave address.
IMPORTANT: When you import a device list, you must also specify the Device type, Device vendor, and Device family, and the Port (502 is default), on the Gateway Discover devices page.
