Status Error
Messages These errors appear as a banner at the top of an application screen (error #634 in
upper left corner) or as Mod/Net LED status on the terminal’s Configuration
screen.
Errors codes 11 or less are minor fault conditions and clear automatically when
corrected. Error codes above 11 require a terminal reset to clear the error.
Message Recommended Action
Too many peer accesses. Only 128 Explicit-Client message channels
are allowed per application. Reduce the number of Explicit-Client Tags in your application.
Translation Failure Contact Allen-Bradley for technical support.
Code Indicates: Recommended Action
1 No connections established. Occurs on power-up until a
device connection is established on the network. Establish a connection over DeviceNet to the PanelView.
2 A connection is in the timed out state. Occurs once I/O
messaging is stopped after an I/O connection has been
running. Check the network wiring and that the master device
(scanner) is operational.
3 An Explicit-Client tag cannot be obtained. Occurs if the
device associated with an Explicit-Client tag is not
responding or the peer tag does not exist at the specified
class, instance, and attribute number. Check the data location is correct and that the end
device is attached and operational. For write tags,
ensure that the appropriate attribute is targeted. If the
targeted device is UCMM capable, ensure it has enough
explicit message connections to allow the PanelView to
take one. If the targeted device is not UCMM capable,
ensure that it is owned by a Master device (scanner).
4 A zero length I/O message was received placing the I/O
application in idle mode. Occurs when the scanner is in
program mode. Error clears when switched back to run. Correct the
problem of the Master sending the I/O idle condition.
5 Message Overrun. Message traffic from the PanelView is
being generated quicker than it is possible to send the
data. Occurs with large I/O sizes when Change-Of-State
is being used and state changes are occurring very
quickly or if polling too fast. Slow down I/O polling or the state changes generating
change of state I/O messages. Use cyclic I/O at a fast
heartbeat rate rather than change-of-state. Use the pro-
duction inhibit capability on the master.
11 No network power detected. Occurs if network 24V is
not present. Check the wiring. Message automatically clears when
24V network power is restored.
12 Dup MAC Failure. Occurs if the PanelView powers up
with the same Node Address present on the network. Change the node address to an unused address and
reset the terminal.
13 Bus-off Interrupt occurred. CAN Chip is held in reset.
Caused by noise on network signal lines or an attempt to
connect to the network at the wrong baud rate. Check baud rate and network wiring, including termina-
tion resistors. Reset the terminal.
