Chapter 7 Diagnostic Web Pages
Idle Nodes
The Idle Nodes page indicates which DeviceNet nodes are currently in the Idle
state. If a node is Idle, the page displays ‘Idle’ next to the node’s MAC ID. Note
that only nodes configured as slaves to the linking device and the linking device
itself are updated on this page.
Faulted Nodes
The Faulted Nodes page indicates which DeviceNet nodes are currently in a
faulted state. If a node is faulted, the page displays ‘Faulted’ next to the node’s
MAC ID. Note that only nodes configured as slaves to the linking device and the
linking device itself are updated on this page.
A node is considered faulted if the linking device has lost communication or is
unable to establish communication with the node. The actual problem can be
determined by viewing the Node Status web page.
Invalid Nodes
The Invalid Nodes page indicates which DeviceNet nodes are not the correct
device type. If a node’s device type is different than that configured in the scan
list, the page displays ‘Invalid’ next to the node’s MAC ID. Note that only nodes
configured as slaves to the linking device are updated on this page.
Node Status
The Node Status page displays the current status of all DeviceNet nodes that are
configured as slaves to the linking device and the linking device itself. The status
of each node is displayed next to the node’s MAC ID. Note that only nodes
configured as slaves to the linking device and the linking device itself are updated
on this page.
The page displays the status textually for many of the common status values.
However, to save web page size, many of the status values are displayed only
numerically. This table describes the meaning of each status value.
Status Code Description Action
0 OK Do nothing.
60 Duplicate MAC ID test in progress Do nothing.
65 Autoscan active Do nothing. The scanner’s autoscan
functionality is active.
70 Module failed Duplicate Node Address check Change the module address to another
available one. The node address you
selected is already in use on that network.
