Error Codes
The following table describes the Error Codes indicated by the
7-segment numeric display.
Table 8.2 Device Status
Code
(decimal)
Name Description Recommended Action
70 Duplicate Node Controller has Failed Duplicate Node Address
Check. The node address selected is already in
use.
Change the module’s or conflicting device’s
network address (node number) to an
available one.
71 Illegal Scanlist Data Illegal data in scanlist. Reconfigure the scanlist table and remove
any illegal data.
72 Slave Timeout One of the module’s slave devices has stopped
communicating.
Inspect the module’s slave devices and verify
the DeviceNet connections.
73 Electronic Key Mismatch The slave device Vendor ID key parameter does
not match the slave’s configuration in the
module’s scanlist.
Make sure that the device at the flashing
node address matches the desired electronic
key (vendor, product code, product type)
75 No Messages Received No network traffic received by the scanner. 10
seconds have elapsed and no network traffic for
the module or for any other device have been
received by the module.
Verify the scanlist is correctly configured to
scan slave devices. Verify DeviceNet
network connections.
76 No Message For Scanner No direct network traffic for the scanner
detected. 10 seconds elapsed and no DeviceNet
input being screened by the module has been
received.
None. There are other active devices on the
network, initiating messages, but none of
the messages are for the module.
77 Slave Data Size
Mismatch
The data being received from the slave device
does not match the configuration in the scanlist.
Either reconfigure the slave device, or
change the module’s scanlist to match the
slave device.
78 No Such Device Slave device in scanlist does not exist. Either add the device to the DeviceNet
network, or delete the device’s entry in the
scanlist.
79 Transmit Failure The module has failed to transmit a message. Make sure that the module is connected to a
valid network. Check for disconnected
cables.
80 In Idle Mode Module is in IDLE mode. Put the controller into RUN mode and enable
the RUN bit in the Module Command Array.
See page 5-8.
81 Scanner Faulted The Scanner has stopped producing and
consuming I/O data. This condition does not
affect the scanner’s system or messaging modes.
Check the FAULT value in the Module
Command Array. See page 5-8.
82 Fragmentation Error Error detected in sequence of fragmented I/O
messages from device.
Check scanlist table entry for slave device to
make sure that input and output data lengths
are correct. Check slave device
configuration.
83 Slave Init Error Slave device is returning error responses when
the module attempts to communicate with it.
Check slave device’s configuration. Reboot
slave device.
84 Not Yet Initialized Module has not completed its initial attempt to
establish communications with its slaves.
None. This code clears itself once the
module properly initializes all slave devices
on the network.
