ModbusTcpGateway is the base container for one or more ModbusTcpGatewayDevice components. This network-level component specifies the TCP/IP address and port used to connect to the Modbus TCP/serial gateway, which has Modbus serial devices (typically Modbus RTU, via RS-485) on its “far side.” Those devices are represented by its child ModbusTcpGatewayDevices.

In addition to standard network components, other Modbus settings are specified in this component. Its primary view is the ModbusTcpGatewayDeviceManager, used to add and manage devices. See About Modbus TCP Gateway networks for additional details.
