Messages, Codes and Self-test Numbers Appendix B
DeviceNet Comm
Status 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 when
I/O polling stops after an I/O poll connection is
running. Check that the network wiring and that the master
device (scanner) is operational.
3 An peer tag cannot be obtained. Occurs if the device
associated with a peer tag is not responding or the
peer tag does not exist at the specified class,
instance, and attribute number. Ensure 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 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 production inhibit
capability on the master.
6 Offline Connection Set Identify Received. An Offline
Connection Set Point-to-Point Identify Message has
been received. Occurs if a Client device on the
network capable of executing the Offline Connection
Set sends a Point-to-Point Identify message to the
terminal while it is in the Offline State. (It failed
Duplicate MAC ID Detection on startup). No action required. The error clears within 500 ms of
the last Identify message sent.
7 A Listen Only connection has timed out. It has not
received a message in at least four times the
expected packet rate value. This occurs if the
message associated with the Listen Only tag is not
occurring or was not identified correctly. Check that the Listen Only tags are properly
configured. Verify that the associated message is
occurring at the expected packet rate. DeviceNet
traffic monitor may be helpful.
10 Autobaud in Progress. Occurs on startup while the
Autobaud process is executing. No action required. The error clears within 10
seconds, the maximum time allowed to detect a
baud rate.
11 No network power detected. Occurs if network 24V
is not present. Check the wiring. This message will clear
automatically when 24V 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
termination resistors. Reset the terminal.
