- Goal is to combine REAL Time control and ethernet.
- take advantage of the improvements of Ethernet networks in terms of transmission bandwidth and network span.
- provide more predictable and reliable real-time data transfer and means for support of precise synchronization of automation equipment.
- real-time,
- synchronized actions between field devices like drives,
- efficient, frequent exchange of very small data records.
- RT - Real-Time: Factory Automation (5-10ms) TCP
IRT - Isochronous Real-Time: drive control , HW support (<1ms)+ Vlan-Tag
