Description

0 4 UDINT Scan Counter The number of DeviceNet I/O scans

that have taken place since power

was applied to the linking device.

4864-bit

Bitstring

Device Failure Register Indicates which DeviceNet slaves are

faulted. Each bit represents the status

of the slave at the corresponding MAC

ID.

12 8 64-bit

Bitstring

Auto Verify Failure

Indicates which DeviceNet slaves are

the incorrect device type. Each bit

represents the status of the slave at

the corresponding MAC ID.

20 8 64-bit

Bitstring

Device Idle Register Indicates which DeviceNet slaves are

in Idle mode. Each bit represents the

status of the slave at the

corresponding MAC ID.

28 8 64-bit

Bitstring

Active Node Register Indicates which DeviceNet nodes are

configured in the 1788-EN2DN’s scan

list. Each bit represents the status of

the slave at the corresponding MAC

ID.

36 4 ASCII[4] Status Display Mimics a 4-character alpha-numeric

MAC ID and its Run/Idle status.

If there are faults, the display will

scroll through the MAC IDs of the

faulted nodes and display the error

code associated with each.

40 1 USINT Scanner Address The DeviceNet MAC ID of the linking

device.

41 1 USINT Scanner Status The current status of the DeviceNet

scanner.
