Hi gh- r esponse Se rvo Sys t em Ach i eved wi t h SSCNET I I I /H

Three Times Faster Communication Speed

Deterministic and Synchronized Communication

Industry leading levels

Communication speed is increased to 150 Mbps full duplex (equivalent to 300 Mbps half duplex), three times faster than the conventional speed. System response is dramatically improved.

Complete deterministic and synchronized communication is achieved with SSCNET III/H, offering technical advantages in machines such as printing and food processing machines that require synchronous accuracy.

SSCNET III

No Transmission Collision

The fiber-optic cables thoroughly shut out noise that enters from the power cable or external devices. Noise tolerance is dramatically improved as compared to metal cables.
