Processor Functional Safety Configuration
The T9110 Processor Module supports a limited set of configuration options;
the system will verify the hardware configuration, such as the module locations
against actual module types.
The processor module process safety time can be specified through the
AADvance Workbench and details are given in theAADvance Configuration
Guide , Rockwell Automation reference 553633
Processor Safety Functions
The processor module is classified as safety critical and is responsible for the
following safety functions:
 solving application logic
 external communication (Ethernet and serial)
 communication with I/O modules such as receiving input values, sending
output values, coordinating diagnostics
 enforcement of system PST
 diagnostics, fault indications and degradation of the processor module
 enforcement of input PST
 diagnostics, fault indications and degradation of input modules
 initiating diagnostics, fault declaration and for some fault conditions the
degradation of output modules
 recovery mode operation
Reaction to faults in the processor module
The processor module reports faults by front panel indicators and fault codes
stored in the System Event log. SYSTEM HEALTHY and HEALTHY
LEDs go RED when a fault is detected in the processor module. Fault
indications are also sent to the user application by variables that you can set up
during the system configuration process. These variables provide the following
information:
 module presence
 module health and status
 channel health and status
 an echo of the front panel indications
