Fragmentation
Error
Error detected in sequence of
fragmented I/O messages from
device.
Check scan list 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.
85
Receive Buffer
Overflow
Data size returned is larger than
expected.
Configure the slave
device for a smaller
data size.
86
Device Went
Idle
Device is producing Idle state.
Check the device configuration and
slave node status.
89
Auto Device
Replacement
(ADR) Error
Slave device responded with an
error to the initialization data sent
to it by the scanner; or the
configuration table in the scanner’s
flash memory is not valid for a slave
node.
Try the ADR download again. If it still
fails, try clearing the ADR flash by
downloading an empty ADR
configuration to the scanner and then
try the ADR configuration again.
90
Disabled
Network
DeviceNet Port is Disabled
Check for the disable being set in the
module command array.
91
Bus Off
Bus off condition detected on
integral DeviceNet port.
Check the DeviceNet connections and
physical media integrity. Check system
for failed slave devices or other
possible sources of network
interference. Check the Baud Rate.
92
No DeviceNet
Power
No network power detected on
DeviceNet port.
Provide network power. Make sure the
module drop cable is providing the
proper power to the DeviceNet port.
95
FLASH Update
Flash Update In Progress
None.
DO NOT
disconnect the module
from the network while a flash update
is in progress.
