ControlNet I/O Map-Entry Status Words and Error Codes D-7
516 0x0204 UNCONNECTED REQUEST
TIMED OUT The ControlNet cable from the
originating node to the target node is
broken or disconnected. Fix and/or reconnect the ControlNet
cable.
The target node is not powered. Supply power to the target node.
The originator’s and/or the target’s
node number is greater than UMAX. Reconfigure the ControlNet network
so that the originator’s and target’s
node numbers are less than or equal
to UMAX.
The target node is too busy to
respond. Reduce the number of unconnected
requests to the target node.
769 0x0301 OUT OF BUFFER MEMORY The maximum number of
connections to/from this node has
been exceeded. • 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.
770 0x0302 SCHEDULED BANDWIDTH NOT
AVAILABLE There are too many words
scheduled for transmission. Edit the I/O map table to reduce the
number of scheduled words.
The network update time (NUT) is
too small. Increase the network update time
(NUT).
The originator’s and/or the target’s
node number is greater than SMAX. Reconfigure the ControlNet network
so that the originator’s and target’s
node numbers are less than or equal
to SMAX.
772 0x0304 NO SCHEDULED
CONFIGURATION The ControlNet cable from the
originating node to the keeper was
broken or disconnected when the
ControlNet network was configured. Fix and/or reconnect the ControlNet

network.
The keeper was not powered when
the ControlNet network was
configured. Supply power to the keeper and
reconfigure the ControlNet network.
The originating and/or target node is
not properly configured to send
scheduled data. Edit the I/O map table of the
originating and/or target nodes to
send scheduled data.
773 0x0305 SCANNER SIGNATURE
MISMATCH The ControlNet cable from the
originating node to the keeper was
broken or disconnected when the
ControlNet network was configured. Fix and/or reconnect the ControlNet
cable. Reconfigure the ControlNet
network by enabling and accepting
edits with RSNetWorx.
The ControlNet processor was not
configured on the current network. Reconfigure the ControlNet network
by enabling and accepting edits with
RSNetWorx.
The ControlNet network was formed
by joining two existing ControlNet
networks. Reconfigure the new ControlNet
network by enabling and accepting
edits with RSNetWorx.
