Device-defined data types

0 = Idle

1 = Run

0 = Connection is active

1 = No connection

0 = No diagnostics active

1 = One or more diagnostics are active or the prognostics threshold is reached

1 through 255

The current value of the Network Status instance attribute of the DLR object for devices with multiple Ethernet ports that support DLR.

0 = Normal

1 = Ring Fault

2 = Unexpected Loop Detected

3 = Partial Network Fault

4 = Rapid Fault/Restore Cycle

The current value of the Ring Supervisor Status instance attribute of the DLR object for devices with multiple Ethernet ports that support DLR.

0 = Device is functioning as a backup

1 = Device is functioning as the active ring supervisor

2 = Device is functioning as a normal ring node

3 = Device is operating in a non-DLR topology

4 = Device cannot support the current ring parameters (Beacon Interval and Beacon Timeout)

Indicates whether the device or port pair is in DLR mode.

0 = Device is not in DLR mode

1 = Device is in DLR mode

0 = Good

1 = Bad

Indicates whether there is a ring fault or linear fault.

0 = Network healthy

1 = Ring or linear fault

0 = Good

1 = Bad

0 = Good

1 = Uncertain

0 = Connection is active

1 = No connection

0 = Half-duplex

1 = Full-duplex

Indicates the status of link auto-negotiation.

0 = Auto-negotiation in progress.

1 = Auto-negotiation and speed detection failed. Using default values for speed and duplex. Default values are product-dependent; recommended defaults are 10 Mbps and half-duplex.

2 = Auto negotiation has failed but detected speed. Duplex was defaulted. Default value is product-dependent; recommended default is half-duplex.

3 = Successfully negotiated speed and duplex.

Indicates network speed.

10 = 10 Mbps

100 = 100 Mbps

1000 = 1000 Mbps

The number of TCP/IP connections currently open to the adapter. This number will change over time, as connections are opened and then closed automatically.

The number of

CIP™

connections currently open to and through the adapter. This tag consists of 1 safety connection plus one connection for each used channel. In addition, a channel with over 24 devices use an additional connection. The max number of expected CIP connections is 7.

A running sum of the number of Sequenced Address Item Sequence Numbers that are skipped in Class 0 and Class 1 connections that the adapter and its children consume.

A running count of the number of connections that time out, both originated and targeted, both to and through the adapter.

The number of Class 3 packets and unconnected packets that the device sends and receives in the previous second.

The number of class 0 and class 1 packets that the adapter transmits and receives in the previous second.

The sum over all ports of the following Ethernet Link object values: In Discards, In Errors, In Unknown Protos, Out Discards, Out Errors, Alignment Errors, FCS Errors, Single Collisions, Multiple Collisions, SQE Test Errors, Deferred Transmissions, Late Collisions, Excessive Collisions, MAC Transmit Errors, Carrier Sense Errors, Frame Too Long, and MAC Receive Errors.

The percentage of the capacity of the compute engine of the product (whether that is a CPU, a core of a CPU, or a thread) most important to the performance of communication of packets by the product. Due to the variations in communication architectures of various products, each product must define this value that is based on its design.
