Industrial Protocols
Industrial Protocols are specialized communication protocols designed for industrial environments, providing reliable, deterministic, and real-time communication between industrial automation devices.
What are Industrial Protocols?
Industrial protocols are communication standards that enable interoperability between industrial devices, providing specific characteristics such as determinism, reliability, and resistance to interference in hostile industrial environments.
