Once Modbus is selected, the user would select the '+' and then "New Modbus" or Add button to create a new Modbus connector.
The user will be prompted with the above popup and the properties to fill out are:
Dis: the name of the connector
ModbusSlave: this would be the slave of the modbus device being connected (default is 1)
Existing Register Map: If the user already configured a Modbus connector, they would see available registers here to choose from or create a new one with the next property ModbusRegMapUri.
ModbusRegMapUri: this is where the user would specify the name of the register map to link with this connector. Replace "xxx" with whatever the name of the register map is.
Uri: this is where the uri of the modbus connector would be specified.
For more details on uri formatting, see Supported Protocols.
In our example, we specified "test" as our register map. Then added our IP to the device in the Uri.
Once the connector is configured, the user would need to create a register map. (The register map could be created first and then chosen when creating the connector. No particular order needed here)
