This
fault
code:
Indicates this fault:
205
ControlNet configuration exceeds processor bandwidth.
IMPORTANT: Scheduled connections will be closed. You must cycle power, save with RSNetWorx,
or download the program to reopen the connections.
Because the configuration software is unable to accurately predict all the resources that the processor
will require to execute your ControlNet configuration software (based on the relative loading on the
processor), this fault code is used if the processor determines that your configuration (typically when you
accept Channel 2 edits) exceeds the processor's available bandwidth.
Typical causes of this error code include:
• receiving data from the ControlNet network faster than the ControlNet PLC-5 processor can parse it
• performing I/O updates too frequently
• performing immediate ControlNet I/O ladder instructions too frequently
See S:74 and S:75 for additional information.

230
System attempted transition to Run mode with processor in Invalid backup state.

And the fault is:
Recoverable
Reduce the number of
ControlNet I/O map table
entries. Possible ways:
• using a discrete rack
connection instead of
multiple discrete module
connections
• combining multiple I/O
racks into a single I/O
rack
• putting peer-to-peer data
in contiguous blocks in
the data table so that less
send and receive
scheduled messages are
required
Increase your Network
Update Time and/or increase
the Requested Packet
Intervals for scheduled data
transfers in your I/O map
table.
Increase your ladder
program scan by either
adding more logic or by
increasing the
Communications Time Slice
(S:77).
Reduce the number or
frequency of immediate
ControlNet I/O ladder
instructions that are
performed.
Contact your local Rockwell
Automation representative if
you get this message.
Contact your local Rockwell
Automation representative if
you get this message.
Recoverable
Delete one or more I/O map
table entries and reaccept
edits for the ControlNet
configuration.
Change from the Invalid
backup state to the No
Control backup state before
transitioning into Run mode.
Refer to the Invalid backup
state troubleshooting table
later in this chapter.
