Troubleshooting Chapter 8
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
81
Scanner Faulted
The scanner module 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
.
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 communication with its slaves.
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 module 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. See
.
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.
