This whitepaper provides a concise overview of selecting and utilizing network switches in industrial automation and machinery operations. In the face of increasing digitalization, reliable and secure data communication solutions are critical. Managed switches offer extensive configuration options for medium to large networks, while smart switches provide controlled flexibility, and unmanaged switches offer simple plug-and-play solutions for smaller networks.

Key factors in selecting switches include compatibility with various protocols, resilience to harsh environments (IP67), security features such as firewalls and encryption, and the scalability of the devices. Diagnostic and monitoring capabilities, like continuous physical monitoring of data lines or EMI influences, aid in error detection and resolution. A cost-benefit analysis is essential to ensure economical investments.

Network switches are crucial components for the reliability and performance of industrial networks. This whitepaper supports professionals in network planning, maintenance, project planning, and procurement in selecting and implementing efficient, secure, and scalable network solutions.
