    Fault Codes This fault code: Indicates this fault: Take this corrective action: ControlNet configuration exceeds processor resources. • Reduce the number of ControlNet I/O map table entries. Possible ways to do this include: IMPORTANT: Scheduled connections will be closed. You must cycle power, save with RSNetWorx, or download the program to reopen - using a discrete rack connection instead of the connections.
