7-4 Troubleshooting
85 Run time data size returned from slave
device is not the size expected. Check slave device installation and
configuration.
86 Device is producing idle state data
while the scanner is in Run Mode. Check device configuration/slave node
status.
87 Available for allocation. Scanner has
not yet been detected by allocated
master, or slave mode is enabled but
scanner is not allocated to a master. Monitor scanner to determine if error
code clears when master detects
scanner. If error remains, check scanner
slave mode configuration.
88 This is not an error. At power-up and
reset, the module displays all 14
segments of the node address and
status display LEDs. None.
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.

port. Module is detecting
communication errors. Check DeviceNet connections and
physical media integrity. Check system
for failed slave devices or other possible
sources of network interference.
92 No network power detected on comm
port. Provide network power. Make sure that
module drop cable is providing network
power to module comm port.
