- Advanced-level topic in Communication Protocols
Detailed Definition
Full-duplex communication protocol over TCP for real-time web-based HMI applications. This term is essential for understanding communication protocols in industrial automation and PLC programming.
WebSocket is one of the protocol or networking concepts an automation engineer encounters as soon as a plant has more than one controller talking to a shared device. Full-duplex communication protocol over TCP for real-time web-based HMI applications.
In practice, WebSocket interacts with the rest of the protocol stack — physical wiring, switch behaviour, controller scan cycle, and the vendor IDE that configures it. A change at one layer often forces a rethink at another.
When commissioning systems involving WebSocket, engineers usually begin with manufacturer-provided diagnostic utilities, then use Wireshark or a protocol-specific analyzer when the vendor tool runs out. Knowing which layer your problem lives on saves hours.
