Key ratings
Controller processing time is stated at 0.00001 ms — fast enough for high-speed logic and communication tasks. The 80 MB RAM (RAM type) is volatile; user data is held only while power is applied. Dual Ethernet interfaces (2 hardware ports) enable network redundancy or daisy-chain topologies without an external switch.
