0 4 UDINT Scan Counter The number of DeviceNet I/O scans
that have taken place since power
was applied to the linking device.
4 8 64-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
Register 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
display. If there are no faults, the
display shows the linking device’s
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.
