Detailed explanation-1: -Gateway. A gateway is a network node that connects discrete networks or systems that use different protocols, enabling data to flow between the networks. Gateways use multiple protocols and translate an incoming packet’s information and protocol to make it compatible with the destination environment.
Detailed explanation-2: -A router is a networking device that sends data packets from one computer network to another.
Detailed explanation-3: -Gateway. Gateway is a network device used to connect two or more dissimilar networks. In networking parlance, networks that use different protocols are dissimilar networks. A gateway usually is a computer with multiple NICs connected to different networks.
Detailed explanation-4: -Being in different networks, the HMI and other devices use different protocols (Modbus TCP and Modbust RTU, respectively). These protocols are bridged by the protocol gateway, allowing the devices to communicate information to the HMI and the HMI to send commands by engineers or operators to different machinery.
