250 µs for RTC3<br />
Baud rate<br />
100 MBit/s<br />
Data transport layer <strong>Ethernet</strong> II, IEEE 802.3<br />
Limitations<br />
RT over UDP not supported<br />
Multicast communication not supported<br />
Only one device instance is supported<br />
DHCP is not supported<br />
IRT “flex” (synchronized RT Class 2) is not supported<br />
FastStartUp is not supported.<br />
Media Redundancy (except MRP client) is not supported<br />
Access to the submodule granular status bytes (IOCS) is not supported.<br />
The amount of configured IO-data influences the minimum cycle time<br />
that can be reached.<br />
Supervisor-AR is not supported, Supervisor-DA-AR is supported<br />
Only 1 Input-CR and 1 Output-CR are supported<br />
Multiple WriteRequests are not supported<br />
Using little endian (LSB-MSB) byte order for cyclic process data instead<br />
of default big endian (MSB-LSB) byte order may have an negative impact<br />
on minimum reachable cycle time<br />
