How can standard-display Web-IOs, e.g. those used in building services engineering or automation, be integrated?
In order to be independent of the wide range of standardized and vendor-specific interface protocols, state-of-the-art display systems use the OPC standard (OLE for process control) to communicate
How can digital signals be tunneled through the network with two Web-IOs?
With the aid of two Web-IOs in box-to-box mode. Here, the only prerequisite for this operating mode is a TCP / IP connection (e.g. also via the Internet) between the two local networks.
How can a Web-IO be made accessible via the Internet?
