71 Illegal data in scan list table Reconfigure the scan list table and remove
any illegal data.
72 Slave device stopped communicating Inspect the field devices and verify
connections.
73 Device’s identity information does not match
electronic key in scan list table entry Verify that the correct device is at this node
number. Make sure that the device at the
scrolling node address matches the desired
electronic key (such as vendor, product code,
and product type).
74 Data overrun on port detected Modify your configuration and check for
invalid data. Check network communication
traffic.
75 No traffic detected on the network Check the network configuration.
76 No direct network traffic for module detected None. The module hears other network
communication.
77 Data size expected by the device does not
match scan list entry Reconfigure your module for the correct
transmit and receive data sizes.
78 Slave device in scan list table does not exist Add the device to the network, or delete the
scan list entry for that device.
79 Module has failed to transmit a message Make sure that your module is connected to
a valid network.
Check for disconnected cables.
80 Module is in IDLE mode Put controller in RUN mode. Enable RUN bit
in module command register.
81 Module is in FAULT mode Check Module Command Register for fault
bit set.
82 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 device is returning error responses when
module attempts to communicate with it Check accuracy of scan list table entry. Check
slave device configuration. Slave device can
be in another master’s scan list. Reboot slave
device.
84 Module is initializing the DeviceNet network None. This code clears itself once module
attempts to initialize all slave devices on the
network.
85 Data size was incorrect for this device at
runtime Slave device is transmitting incorrect length
data. Try replacing the device.
86 Device is producing zero length data (idle
state) while module is in Run mode Check device configuration and slave node
status.
87 The primary owner has not allocated the slave Put the primary owner on line.
88 The connection choices (such as polled or
strobed) between the primary connection and
the shared input only connection do not
match Reconfigure the shared input only
connection's choices to be the same as, or a
subset of, the primary connection's
choice(s).
89 Slave device initialization using Auto Device
Replacement parameters failed Put the slave device into configurable mode.
Check the slave's EDS file, if the slave is
configured offline.
Check to see if the slave device has been
replaced with an incompatible device.
90 User has disabled communication port Check Module Command Register for
DISABLE bit set.
