Fully compatible with standard Ethernet, the Harting's Fast Track Switches guarantee deterministic data transmission at the fi eld level. This makes it possible to meet high real-time requirements in automation without changing the standard Ethernet. No special hardware is required in the terminal units. The switches guarantee on-time data transport. This works for various automation profi les, such as Profi lnet RT, Ethernet/IP, ModbusTCP and all other.
