main purpose
Used for reflective memory real-time networks, often used for simulation, testing, and high-speed distributed control systems;
Connect multiple reflective memory cards to the same real-time shared memory network to achieve microsecond level data synchronization between multiple controllers;
Not a regular Ethernet switch, it is a dedicated real-time hardware network and cannot be directly connected to a regular PLC Ethernet port.
