a ControlLogix tag that does not
exist.
The PLC-5C does not support
ControlNet hot backup. Refer to
publication 1785-6.5.24 for more
information.
The target node does not support
ControlNet Hot Backup.
The target node/module does not
match the node/module entered in
the map table.
The originating node attempted to
open a listen-only connection before
the owner connection was opened.
The CIO instruction failed because
the 1771 discrete rack has no
owner.
The ControlNet cable from the
controlling node to the target node is
broken or disconnected.
The controlling node is not powered.
The target 1771 adapter is in
Processor Restart Lockout.
The maximum number of
connections to/from this node has
been exceeded.
The ControlNet cable from the
originating node to the target node is
broken or disconnected.
The target node is not powered.
Possible Corrective Action(s)
Change the PLC-5C I/O map entry to
use the correct tag.
Change or add the tag to the
ControlLogix processor.
Verify that the PLC-5C is a Series F
PLC-5/40C or -5/80C.
Verify that the 1785-CHBM Hot
Backup module is properly installed.
Replace the target node with one
that supports ControlNet Hot
Backup.
Replace the target node/module
with the correct node/module.
Verify that the target node/module is
powered up.
Correct the map table.
Correct any connection errors
associated with the owner
connection.
In the I/O map table, add a discrete
connection for the 1771 I/O rack.
Fix and/or reconnect the ControlNet
cable.
Supply power to the controlling
node.
Press the reset button on the target
1771 adapter.

• If this is an I/O connection, reduce
the number of I/O connections.
• If this is a MSG instruction,
reduce the number of MSG
instructions.
• If this is a CIO instruction, reduce
the number of CIO instructions.
Fix and/or reconnect the ControlNet
