Status

Get

DWORD

-

Bit:

Meaning:

(reserved, set to 0)

0–3

When set to h, attribute #5 contains valid configuration from DHCP or non-volatile storage. When set to 2h, attribute #5 contains valid configuration from hardware settings. Remaining values are reserved for future use.

4

Multicast pending if set to 1.

5

Interface configuration pending if set to 1. A new configuration will be loaded at the next reset.

6

AcdStatus. Set to 1 if an address conflict is detected. Address conflict detection is enabled/disabled in attribute #10.

7

AcdFault

8–31

(reserved, set to 0)

2

Configuration Capability

Get

DWORD

-

Bit:

Meaning:

0-1:

Always 0. For more information, consult the CIP specifications.

2

If set to 1, the device is capable of acting as a DHCP client. The bit is set to 0 if attribute #24 (Enable DHCP Client) is disabled in the Ethernet Host Object (F9h)

3

Always 0. For more information, consult the CIP specifications.

4

The ‘Configuration Settable’-bit reflects the value of instance attribute #9 in the EtherNet/IP Host Object (F8h).

5

The module is hardware configurable when this bit is set to 1. The bit will be set if any of the address attributes is set in the Network Configuration Object (04h) during setup or if attribute #6 (Hardware configurable address) in the Application Object (FFh) is set.

6

Always 0. For more information, consult the CIP specifications.

7

If set to 1, the device is capable of detecting address conflicts. The bit is set to 0 if address conflict detection is disabled in the Ethernet Host Object, see page Ethernet Host Object (F9h)

8 - 31:

(reserved, set to 0)

3

Configuration Control

Get/Set

DWORD

-

Value:

Meaning:

0:

Configuration from non-volatile memory

2:

Configuration from DHCP

8

TTL Value

Get/Set

USINT

1

TTL value for EtherNet/IP multicast packets

9

Mcast Config

Set

Struct of:

IP multicast configuration.

Alloc Control

USINT

0

Value:

Meaning:

0:

Use default allocation algorithm to generate multicast addresses

1:

(reserved)

USINT

0

Set to zero. Do not change.

Num Mcast

UINT

-1

Number of multicast addresses to allocate for EtherNet/IP

Mcast Start Addr

UDINT

-

Starting multicast address from which to begin allocation

10

SelectAcd

Value:

Meaning:

0:

Disable ACD

1:

Enable ACD (Default). If ACD (address conflict detection) is enabled, bit 6 in attribute #1 will be set if an ACD conflict is detected. The Network Status LED will also indicate a detected conflict, see Front View.

11

LastConflictDetected

Set

Struct of:

ACD Diagnostic parameters related to the last conflict detected.

AcdActivity

USINT

-

State of ACD activity when last conflict detected.

RemoteMAC

ARRAY of 6 USINT

-

MAC address of remote node form the ARP PDU in which a conflict was detected.

ArpPdu

ARRAY of 28 USINT

-

Copy of the raw ARP PDU in which a conflict was detected.

12

EIP QuickConnect

Encapsulation inactivity timeout

Set

UINT

0 - 3600

Number of seconds of inactivity before a TCP connection is closed. 0: Disabled

  • Support for configuring network settings (attributes #3 and #5) from the network can be disabled by implementing attribute #9 in the EtherNet/IP Host Object, see EtherNet/IP Host Object (F8h)

  • Attributes #10 and #11 will not be available if ACD is disabled using attribute #11 in the Ethernet Host Object (F9h).

  • Attribute #12:

    • If the module is configured to use EIP QuickConnect functionality, the EDS file has to be changed. As the EDS file is changed, the identity of the module has to be changed and the module will require certification.

    • This attribute exists if attribute #26 in the EtherNet/IP Host Object is implemented, see EtherNet/IP Host Object (F8h).
