B.1 Fatal Error Codes and Messages
Fatal errors cause the CPU to stop the execution of your program. Depending on
the severity of the error, a fatal error can render the CPU incapable of performing
any or all functions. The objective for handling fatal errors is to bring the CPU to a
safe state from which the CPU can respond to interrogations about the existing
error conditions.
The CPU performs the following tasks when a fatal error is detected:
Changes to STOP mode
Turns on both the System Fault LED and the Stop LED
Turns off the outputs
The CPU remains in this condition until the fatal error is corrected. Table B-1
provides a list with descriptions for the fatal error codes that can be read from the
CPU.
