 An interesting application is the connection of heterogeneous systems to each other when WebHMI devices are installed in different systems, allowing them to exchange data among themselves. In this case, for example, to read the register using the Modbus / TCP protocol from another WebHMI device, you need to use the address in the format IRxxxxx (where xxxxx is the server address).  An interesting application is the connection of heterogeneous systems to each other when WebHMI devices are installed in different systems, allowing them to exchange data among themselves.
