NOTICE
The warning threshold for CPU load is 70%, the switch-off threshold is 90%. If
the 90% CPU load is exceeded, the safety CPU switches off.
■
The following table describes the information of the bits (0 ... 15) in the diagnostic
status register (SPLC.DIAG.STATUS_REG.xxx).
Type - description
SPNSV2_TYPE - Data structure
BOOL - Non-safe debug operation of the safety CPU.
■
BOOL - There is an entry in the error memory of the safe oper-
ating system (error stack) of the safety CPU. Diagnostic and error
messages from the safe operating system of the safety CPU are
available.
■
■
■
BOOL - Failure state of the safety CPU.
■
■
BOOL - Initialization of the safety CPU.
■
BOOL - Initialization of the safety I/O channel communication.
■
BOOL - PowerON process.
■
BOOL - PowerON self-test of the safety CPU (POWER ON SELF
TEST).
■
BOOL - Load and start the safety application program.
■
The safety CPU is in one of the two DEBUG states (DEBUG-
RUN or DEBUG-STOP/DEBUG-HALT).
These messages can be read and analyzed via iCube Engineer.
The variable always has the value TRUE if at least one entry is
contained in the error memory of the safety operating system.
As soon as the error memory was read via iCube Engineer and
thus cleared, the value of the variable changes to FALSE.
An error was detected that puts the safety CPU in fail safe state.
⮫ 'Fail safe states'...page 130
In this state, the associated, more detailed error code is con-
tained in the diagnostic parameter registers of the safety CPU
(SPLC.DIAG.PARAM_REG and SPLC.DIAG.PARAM_2_REG).
The initialization of the safety CPU firmware (safe operating
system) was completed without errors.
The initialization of the FSoE communication to the I/O devices
was completed without errors.
The safety CPU is powered. The firmware was loaded into the
RAM memory of the safety CPU and booted up. The self-test
routines of the safety CPU were completed without errors.
Self-test of the safety CPU active after PowerON.
The safety-related application programme created with iCube
Engineer was loaded into the safety operating system of the
safety CPU and started without errors.
