in Idle mode.
Each bit represents the status of the

271 4 64-bit Bit-
string
Active Node
Table
Indicates which DeviceNet nodes are
configured in the BridgeWay’s scan
list. Each bit represents a device at the
corresponding MAC ID. If the bit is
set, that device is being actively
scanned by the BridgeWay’s
DeviceNet master.
275 2 ASCII[4] Status Display Mimics a 4-character alpha-numeric
display.
If there are no faults, the display indi-
cates the BridgeWay 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. See
Table 10-6, “Node Status Codes,” on
page 6 for a list of error codes.
