ControlLogix DeviceNet Scanner Module 31
Publication 1756-IN566D-EN-P - June 2008
78 Device is configured in scan list, but
not communicating. It has failed to
communicate during the scanner’s
second scan, which followed the
display of status error code 72. Verify device’s:
• power.
• communication connections.
If the device is polled, make sure the
interscan delay is long enough for the
device to return its data.
If necessary, use RSNetWorx for
DeviceNet software to do the following.
• Add the device to the DeviceNet
network.
• Delete the device from scanner’s
scan list.
• Inhibit the device in the scanner’s
scan list.
79 Scanner has failed to transmit a
message. The error status usually
displays after the duplicate node
check completes when power is
applied to the module.
• Make sure that your scanner is
connected to a valid network.
• Check for disconnected cables.
• Verify the network communication
rate.
80 Scanner is in Idle mode. 1. Put the controller in Run or
Remote Run mode using the
keyswitch on the controller, or
through RSLogix5000 software.
2. Turn on the bit
O.CommandRegister.Run for the
scanner.
81 Controller has set the scanner to
the faulted mode. The Command bit
also indicates a DeviceNet network
fault state. Bit O.CommandRegister.Fault for the
scanner is on. Correct the condition that
caused controller to set this bit and then
turn this bit off.
