For a single fault deemed by the system to be a "critical failure" the processor
module enters the Recovery Mode.
Recovery Mode
Recovery Mode is a shutdown mode and uses a base level firmware. It is
entered automatically when a critical firmware failure occurs or it can be
entered manually by pressing the processor Fault Reset button immediately
after the module has booted up.
As an alternative firmware version it allows the following maintenance
activities:
 Update the firmware using the ControlFLASH utility
 Program the processor IP Address with the AADvance Discover utility
 Extract diagnostic information
In Recovery Mode the Ready, Run, Force and Aux LEDs go Amber and the
Healthy and System Healthy LEDs stay Green. The System Healthy and
Healthy LEDs may go Red if a fault is detected while in the Recovery Mode.
Note: When in Recovery Mode the I/O communications are disabled and the
Application code is not running.
Processor Module Locking Screw safety Function
The module locking screw acts as a module retaining device and also as a
switch that controls the module's operation. For the module to be fully
operational the locking screw must be turned to the locked position. If the
screw is turned to the unlocked position when a module is operational it will
initiate a fault indication and the module will become non-operational.
Processor modules can be replaced or installed on-line without affecting the
controller operation provided at least one is fitted and is fully operational.
However, each module must be installed one at a time and allowed to educate
before the next module is installed.
Processor Module Access Port
The front panel of the T9110 Processor Module has a concealed PS/2 style
connector on the front panel behind a plastic cover. This connector is for
Rockwell Automation use only and is used for factory settings during
manufacturing. However, the plastic cover can be removed to replace the
processor battery.
