Chapter 5 Troubleshooting and Rectifying Module Faults
Rectify a Critical Processor
Firmware/Hardware Failure
When a critical firmware failure occurs, such as a software watchdog failure,
or a self-test detects a hardware failure, the processor module will
automatically reboot into Recovery Mode. In Recovery mode the application is
stopped and the following status indications occur:
• Collect the logs from the processor and send them to Rockwell
Automation (http://rockwellautomation.custhelp.com
) for analysis by
technical support.
alternatively,
• Install a new processor module and get an RMA number to return the
faulty module. See Return a Module
on page 12 for more information.
Install a 9110 Processor Module
Do the following:
• Before inserting a new processor module, examine it for damage.
• The identification labels on the sides of the module will be hidden after
the module is installed. Therefore before installation make a record of
the location of the module and the details shown on the label.
• If you are installing more than one processor module make sure they all
have the same firmware build.
Installation
1. Examine the coding pegs on the 9100 processor base unit and make sure
they fit the sockets on the rear of the processor module:
