Context Management by CL-RPC
Supported
Identification & Maintenance
Read and write of I&M1-4
Minimum cycle time
1 ms for RTC1 and RTC2
250 µs for RTC3
Baud rate
100 MBit/s
Data transport layer
Ethernet II, IEEE 802.3
Limitations
RT over UDP not supported
Multicast communication not supported
Only one device instance is supported
DHCP is not supported
IRT “flex” (synchronized RT Class 2) is not supported
FastStartUp is not supported.
Media Redundancy (except MRP client) is not supported
Access to the submodule granular status bytes (IOCS) is not supported.
The amount of configured IO-data influences the minimum cycle time
that can be reached.
Supervisor-AR is not supported, Supervisor-DA-AR is supported
Only 1 Input-CR and 1 Output-CR are supported
Multiple WriteRequests are not supported
Using little endian (LSB-MSB) byte order for cyclic process data instead
of default big endian (MSB-LSB) byte order may have an negative impact
on minimum reachable cycle time
