Additional Information
1.When the serial Modbus device is running in Modbus/RTU Slave mode, the NPort Modbus Gateway is ready to connect automatically to Modbus/TCP Master devices. Up to 7 Modbus/TCP master devices can connect to one serial Modbus slave device.
2.Modbus ASCII Slave mode works the same as Modbus/RTU slave mode, except that the data format is Modbus/ASCII.
3.When the serial Modbus device is running in Modbus/RTU Master mode, the NPort Modbus Gateway is ready to connect automatically to Modbus/TCP slave devices. You will also need to configure the IP address for up to 4 Modbus/TCP slave devices that can be connected to over the Ethernet network.
