1) The variables reflect the startup status of the safety CPU. The start-up sequence is as follows:
–
PowerON process
–
Initialization of the safety CPU.
–
Loading and starting the safety application program.
–
Synchronization of safety and standard components within the safety CPU.
–
Initialization of safety I/O channel communication.
■
2) The variables indicate the RUN and DEBUG safety CPU operating states.

The diagnostic status register SPLC.DIAG.STATUS_REG contains the status informa-
tion of the safety CPU. It reflects the status of the safety CPU including any error
states of the safety CPU that may have occurred at any time. Additional information
and error parameters, especially in the fail safe (FS) state, are contained in the asso-
ciated diagnostic parameter registers of the safety CPU (SPLC.DIAG.PARAM_REG
and SPLC.DIAG.PARAM_2_REG) and in the extended diagnostic parameter register
(SPLC.DIAG.EXT_PARAM_REG).

Bit 4 ... 0: Start-up status of the safety CPU.
–
PON - Power ON process completed.
This bit is set as soon as 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 successfully completed.
–
INIT - Initialization of the safety CPU completed.
This bit is set as soon as the initialization of the safety CPU firmware (safe oper-
ating system) was completed without errors.
–
PRO - Safety user program loaded and started.
This bit is set as soon as the safety user program, which was created with iCube
Engineer, was loaded into the safety operating system of the safety CPU and
started without errors.
–
SYN - Synchronization of safety and standard components of the safety CPU.
The bit is set when the safety and standard components of the safety CPU are
synchronized.
–
I/O - I/O channel communication initialized.
This bit is set as soon as the initialization of the safety CPU firmware (safety
operating system) was completed without errors.
■
Bit 6, 5: Operating status of the safety CPU:
–
RUN - RUN operation of the safety CPU.
This bit is set if the safety CPU is executing the safety user program and is in one
of the two RUN states (SAFE-RUN or DEBUG-RUN).
–
DBG - Non-safe debug operation of the safety CPU.

BOOL - Execution of the safety application program (RUN).
■
The safety CPU executes the safety application program and is
in one of the two RUN states (SAFE-RUN or DEBUG-RUN).
BOOL - Synchronization of safety and standard components within
the safety CPU.
■
The synchronization of the safety and standard components
within the safety CPU was successfully completed.
BOOL - Safety CPU warning.
■
There is a collective warning message from the safety CPU.
