Topology information
The Link Layer Discovery Protocol (LLDP) is used to detect the network neighborhood and thus
also to determine topology information. The status of individual connections can be read out at
any time.
Network diagnostics
The Simple Network Management Protocol (SNMP) is used to support network diagnostics. The
ATD430W IO device supports MIB-II for TCP/IP in accordance with RFC1213.
Port-related statistics
The topology presentation data is stored in the physical device of the ATD430W IO device. The
PDEV data is addressed as from subslot 0x8000. From a communication perspective, the
ATD430W IO device always consists of the interface and the ports 1 and 2.
The PDEV is represented by the following submodules of the device access point (DAP):
• Submodule 0x8000 → Interface
• Submodule 0x8001 → Port1
• Submodule 0x8002 → Port 2
Automatic addressing
The Discovery and basic Conguration Protocol (DCP) is compulsory for the automatic
assignment of IP addresses.
Media redundancy
In the case of PROFINET, the Media Redundancy Protocol (MRP) is used for the media redundancy
of ring topologies. The ATD430W IO device assumes the role of an MRP client. The MRP manager
function is not supported.
