Project description

OPC-UA has existed since 2008. It is a server architecture that supports multiplatform applications.The simplest implementation is connecting clients to a web server that responds to client queries and receives GET data with a request.Architecture is used in microprocessor communication, automation systems with PLC, simple sensor networks.In an advanced implementation, it is also possible to use an HTTPS connection to verify the WebServer / Client / Server certificate.Demonstration implementation shows easy connectivity between boards on the ESP8266 platform using an HTTP web server.In this…
