requests to the target node.
• 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.
Edit the I/O map table to reduce the
number of scheduled words.
Increase the network update time
(NUT).
Reconfigure the ControlNet network
so that the originator's and target's
node numbers are less than or equal
to SMAX.
Fix and/or reconnect the ControlNet

network.
Supply power to the keeper and
reconfigure the ControlNet network.
Edit the I/O map table of the
originating and/or target nodes to
send scheduled data.
