Settings are managed via the host system configuration software.\u003c\/p\u003e\n\u003cp\u003eQ: Does the dual-port architecture support bumpless redundancy transfer?\u003c\/p\u003e\n\u003cp\u003eA: The dual-port design facilitates redundant network pathing. Switchover logic is governed by the host controller's redundancy algorithms, ensuring minimal latency during fault detection and path transition.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the module onto a standard industrial DIN rail.
