Instance attribute "Status" (attribute 1)
8 Get / Set TTL Value USINT TTL value (C13019 / C14019) for EtherNet/IP
multicast data packets
(value range: 1 ... 255)
9 Get / Set Mcast Config: STRUCT of: Configuration of the multicast IP addressing
Alloc Control USINT Control word (C13018
/ C14018) for
addressing:
• 0: The multicast IP addresses are
generated with the standard assignment
algorithm.
• 1: The multicast IP addresses are assigned
via the values in "Num Mcast" and "Mcast
Start Addr" (C13006
/ C14006)
•2: Reserved
Reserved USINT 0 (0x0000)
Num Mcast UINT Total number of multicast IP addresses
assigned (C13020
/ C14020)
Mcast Start Addr UDINT Active multicast IP start address (C13016
/
C14016
)
10 Set SelectAcd BOOL Activation of address conflict detection (ACD,
C13846
/ C14846)
•0: Disable ACD
•1: Enable ACD
Changing this value requires a reset of the
device ("power off/on" or "type 0 reset").
11 Get / Set LastConflictDetected: STRUCT of: ACD diagnostics information about the last
occurred address conflict
AcdActivity USINT Status of the ACD algorithm when the last
address conflict occurred:
• 0: NoConflictDetected (default)
• 1: ProbeIpv4Address
• 2: OngoingDetection
•3: SemiActiveProbe
RemoteMAC ARRAY of
USINT[6]
MAC address of the device with the last
address conflict
ArpPdu ARRAY of
USINT[28]
Reproduction of the ARP message with
information about the address conflict

Bits Name Description
0 ... 3 Interface Configuration
Status
• 0000: No TCP/IP configuration available (attribute 5)
• 0001: Valid TCP/IP configuration (attribute 5) via BOOTP, DHCP or
static/permanent storage
• 0010 ... 1111: Reserved
4 Mcast Pending This bit indicates a pending change of the multicast configuration in
attribute 9 (Mcast Config) and/or the TTL value (C13019
/ C14019). It is
set to ’1’ if either a multicast attribute or the TTL value is set.
The pending change will only take effect after a reset of the device
("power off/on" or "type 0 reset"). This bit is then reset to ’0’.
5 Interface Configuration
Pending
This bit indicates a pending change of the TCP/IP configuration in
attribute 5 (Interface Configuration). It is set to ’1’ if an attribute is set.
The pending change will only take effect after a reset of the device
("power off/on" or "type 0 reset").
